Playback or Conversion of QNAP Surveillance Video Recordings

Playback or Conversion of QNAP Surveillance Video Recordings
   84

QNAP includes “Surveillance Station” as an application on their NAS devices, which allows you to setup security camera’s throughout your house or business. It supports numerous camera’s, motion detection, alert messages etc.

One problem I did run into however, was that the recordings of my Foscam IP-camera’s could not be played in any of the media players I had on my Mac, only to find out that Windows and Linux users can experience the same problems.

With a simple trick and free software you can either modify the AVI files (very quick!) or convert the videos to another format. The presented tricks work for MacOS X, Linux and Windows.




Playback of QNAP Surveillance Video Recordings

You probably already know this, the recordings of Surveillance Station can be found in the “Recordings” share on your QNAP, where you will find AVI files of the recordings that have been made, depending on your settings of course.

Note : QNAP got the annoying idea to request purchase of licenses for each camera connected to your QNAP. Previous versions did not require the expensive license, and the latest versions come with only one courtesy license.

The recording format capabilities strongly depends on your camera’s capabilities, since the QNAP does not transcode the video’s.

My Foscam 8910 camera’s seem to like Motion JPEG (MJPG), but other camera’s support h264 etc. In this article I’ll focus on the video’s from my Foscam, but as I have seen in numerous forums, this trick will work for most cheaper IP camera’s as well.

When you try to open one of the QNAP Surveillance Video Recordings, you will most likely get an error message, as for example in VideoLAN VLC as seen below. Notice the ‘VLC does not support the audio or video format “qIVG”.‘ message, where qIVG is the so called FourCC of the video stream.

Other media players will give error messages as well, or simply do nothing at all. Often they lack the detailed information we see with VideoLAN VLC.

Option 1 – Patching the AVI file

If you see the “qIVG” message, then changing the FourCC of the AVI file will fix the issue. It appears that “qIVG” can be played with a Motion JPEG (MJPEG or MJPG) codec.

Note that other camera’s might use different format, I unfortunately do not have any other camera’s to test other formats with.

For this we can use several applications like abcAVI and FourCC Changer, but both are only available for Windows. Instead I use a program I created my self: AVI FourCC Fix. You can download it below, or you can look at the article I wrote about how to use this free application.

Please note that the newer MPEG4 files from your QNAP (FourCC: q264) can be converted with AVI FourCC Fix v1.1 as well (to: H264).

AVI FourCC Fix - FourCC changer for most platforms

AVI FourCC Fix – FourCC changer for most platforms

The procedure is simple:

  • Add files to the list (Click “Select Video Files” or use Drag and Drop)
  • Click “Make a Backup“, which is optional but recommended since the original files will be modified.
  • Click the “Fix QNAP Recording” button to set the correct FourCC codes.
  • Finally click “Change FourCC” which fixes all AVI’s in the list rather quickly, even for files on network shares.

 

After this procedure your AVI files will play just fine with for example VideoLAN VLC.

Option 2 – Convert the recording to a different Video Format

The second option is to convert the QNAP Surveillance Video Recordings to a different format, and here the free ffmpeg is very helpful. You can find ffmpeg for several platforms on the ffmpeg homepage. I did however find it rather confusing to find a pre-compiled versions for specific platforms. In short, you can find some builds here:

There are plenty other locations to find pre-compiled ffmpeg builds, some of them you can find on the ffmpeg downloads page.

For this we will use the command line and I’ll show you an example for one file and one for multiple files – conversion is relatively fast, but strongly depending on your computer speed.

ffmpeg Documentation 

For more details, like supported audio and video codecs, quality settings, and other options, please read the ffmpeg Documentation.

One file conversion at a time with ffmpeg

With ffmpeg you can convert one file at a time with the following command line statement. The example below only converts the video, as most recordings do not have audio:


1
ffmpeg -i qnaprecording.avi -vcodec libx264 -an qnaprecording.m4v

If you do have recordings with audio then the following statement can be used (removed the “-an”):


1
ffmpeg -i qnaprecording.avi -vcodec libx264 qnaprecording.mp4

In both examples, you of course have to replace “qnaprecording.avi” with the filename of the AVI file you’d like to convert. “qnaprecording.m4v” or “qnaprecording.mp4” will be the name of the newly created file.

Batch conversion with ffmpeg (Linux/MacOS X)

Below an example of a script (works under MacOS X and Linux) in which I used above statements to convert all AVI’s found in the mentioned directory. The example below uses conversion without audio, but removing the ” -an” (do not remove the double quotes) from the 3rd line will convert audio as well.

Save the code below in a plain text file, for example called “convert”, and use  chmod +x convert   to make it executable. On the commandline type  ./convert  to execute your script.

Don’t forget to change the “MOVIES” variable in line 2 to the location where your recordings are.


1
2
3
4
#!/bin/bash
MOVIES=/Volumes/Recordings/
find "$MOVIES" -name '*.avi' -exec sh -c '~/Desktop/ffmpeg -i "$0" -vcodec libx264 -an "${0%%.mp4}.m4v"' {} \;
exit;

          Your fix has fixed my file from the foscam 8904. My other camera is a foscam 9805. When I try to play those files back I get a similar error but q264 is mentioned. This is trying to play in vlc.

          Got it! 

          You could try the following FourCC code’s (if it’s an AVI):
          – AVC1
          – H264
          – h264
          – X264
          – x264
          – DAVC
          – LMP4
          – SVQ3
          See also: MSDN and FourCC.org
          Please let us know if any of these work … I’m sure others will run into the same issue (specially when I order my own HD Foscam camera)

    Hi Hans, I have the same issue as Andy: Qnap with a Foscam 9805. I tried the FourCC code’s you suggested but I can’t play the video file from VLC on OSX.

    If you still don’t own an h264 cam I can share one of my AVI file so maybe you can help us to solve the issue:

    During playback in VLC, VLC mentions that it can’t handle “q264“.
    Change this to “H264” and your AVI plays just fine.

    In the FourCC Fix, set in the “FourCC Change” box:

    Current: q264
    New: H264

    and press the “Change FourCC” button …

    The AVI now plays in VLC without a problem … (tested with the test file of Franco)

    Hello, I tried manually inputting q264 for the current codec and change it to H264.  The video plays without a hitch on the Mac VLC.  The issue is I lost the audio to the video file.  Is anyone else having the same issue?  Thanks.

      I apologize, I’ve never payed attention to the audio track … 

      If anyone runs into what 4CC needs to be changed to get the audio code right, then please post it here.
      Once I’m back home (traveling at the moment), I’ll try to take a look as well.

        I have to examine the audio track codec. The example from Franco (see link above) does not seem to have an audio track (after applying the FourCC trick), which I just tried …

        @Franco: Can you confirm that there is no Audio in your example?

        If anyone has a recording with audio, then please post a link here so I can check it out (with the limited resources I have at hand while traveling).

            Reading the manual, I’ve just discovered that in order to get audio recording for 9805W you need to use and external mike connected to the yellow female rca connector (and I didn’t just because I don’t care about it…)

          Dear Hans, please find below two files for your consideration.  One is the original video file captured on my QNAP unit.  The other is the altered file using your tool.  The following is what’s happening:

          1. VLC for Mac can play the altered file with no audio.  VLC for Mac CANNOT play the original file.

          2. VLC for PC can play the altered file with audio.  VLC for PC CANNOT play the original file.

            This would suggest that the audio codec might be missing under MacOS X – but I would expect VLC to complain about that (which it doesn’t seem to do) … I’ll take a look and see what I can do – thanks for posting the files!

            Checking the files with ffprobe gives me:

            Duration: 00:05:07.23, start: 0.000000, bitrate: 7239 kb/s
                Stream #0:0: Video: h264 (High) (q264 / 0x34363271), yuvj420p(pc), 1280x720, 30 fps, 30 tbr, 30 tbn, 25 tbc
                Stream #0:1: Audio: none ([38][247][0][0] / 0xF726), 8000 Hz, 1 channels, 8 kb/s
            Unsupported codec with id 0 for input stream 1

            So, on a Mac that Audio format is not even recognized by ffProbe/ffMPEG which would explain why VLC does not see the stream even after doing a FourCC on the video stream … (codec is not defined ie: “none”)

            As soon as I can lay my hands on a Windows machine, I’ll try ffProbe there to see what is says under Windows. Obviously Windows somehow knows what to do with it.

            Hi Quassum,

            I have not found a proper solution for the audio (yet).
            It seems that the used codec is “weird” or non-standard, or simply none existing (see comment of Franco).

            When you convert with ffmpeg, I assume your recordings do have audio.

            In the QNAP Forum I did see a post claiming that the latest (or beta) release of VLC should play the video’s without the need to convert them – it’s worth a try.

            Hi Hans,

            after converting with ffmpeg the file does have audio, VLC identifies the codec as MPEG AAC Audio (mp4a). Maybe this helps?

        • Nov 15, 2015 - 9:21 AM - hans - Author: Comment Link

          @Quassum:

          So the original has Audio.
          Can you see with ffmpeg what the original audio codec is?

          If I recall correctly, ffprobe (which could be included with the ffmpeg you’re using) should be able to list the codecs of the original file:

          ffprobe videofile.avi

            As far as I can find, that codec cannot be “swapped” by simply changing the 4CC.
            Not to mention: I don’t know what the 4CC for “pcm_mulaw” is.

            I’ve looked around with the help of Mr. Google – no dice so far.
            To change the 4CC we would have to determine the 4CC to replace first, so we can experiment.

            Maybe a program like GSpot or abcAVI Tag Editor (both Windows only) could provide an insight.

            4CC though is more geared towards video, so my application might not be able to address this issue.

            What kind of camera are you using? Foscam?

            Hi Quassum!

            I recall your AVI file, and recall having looked at it. Since I didn’t have much time (moving around a lot), I didn’t find a proper for the “none” type Audio. 

            Now that I had another codec question, I wanted to look at yours again to see if there was a trick – but I have no idea where I left your AVI file (I was working with another computer).

            Sounds though that these two might be related. Any chance you can send it again?

          I made some progress (by accident) with your sample video with ffmpeg. It’s not yet perfect so I’ll be toying some more with it.

          When I do this with ffmpeg (which goes relatively fast):

          ffmpeg -i original.avi -vcodec h264 test.avi

          Then video and audio works! However … it seems to drop an awful lot of video frames.
          By the way; audio quality is crappy (not surprising with only 8kbps).

          I’ll keep playing with it some more.

            Yup, that was what I’m doing right now already, only with -vcodec libx264. Was hoping there was a more elegant and fast solution that just patched the files though.

            Well, I’m hoping to find where exactly to “patch” the file to get the file going …
            Is the motion correct? I did see a lot of dropped frames during conversion.

            I also tried just copying the video stream (-c:v copy), but ffmpeg simply fails on that one. Either it will not copy the video or it gives an error message.

          Would you be able to send a test file with a little bit more motion?
          At times it’s very hard to see if the frames actually get dropped or if the video is supposed to be this way?
          Right now I just see a window, and hear music.

            Frames are actually dropped I can tell you from experience, it’s very noticeable. I have to find a suitable scene if it’s really better to have something constantly moving.

            Well, you could just record a few seconds while moving the camera around a bit (just move it left/right – just enough to see that there is motion). And with some effort I can see that it’s dropping frames as well. Just not as obvious, since I cannot play the original file haha

            I just tried this:

            ffmpeg -i original.avi -r 5 -preset ultrafast -b:v 100k test.mp4

            Which results in the same frame dropping, just seemed easier to type

            Just uploaded another sample with audio and a bit more movement, hope it helps.

            I managed to convert the file with ffmpeg – but it really drops a lot of frames, although in the video (good thinking with the iPhone timer!! ) doesn’t show issues with the dropped frames after conversion.

            ffmpeg -i Test_Tweaking4All_2.avi -vb 750k test2.mp4

            The audio track however, remains a weirdo. I fear that there will be no way to make it playable without conversion.
            When using ffmpeg and copy the video anc convert the audio, we only endup with audio, however … 

            After doing this:

            ffmpeg -i Test_Tweaking4All_2.avi -c:v copy test3.avi

            It’s quick (seconds!) and converts audio, but copies video (no video transcoding), and after that apply the Avi FourCC Fix for the new MP4 format, then we suddenly have an AVI that does play!

            So in short:

                1) ffmpeg -i YourFoscam.avi -c:v copy YourFoscamWithAudioConverted.avi
                2) Apply “Fix MP4 (new)” in “Avi FourCC Fix” on the “YourFoscamWithAudioConverted.avi

            And then you have, relatively quickly, a working AVI file! 

            I used ffmpeg 3.0, on a Mac, and playback with VLC. Please try this and see if it work for you.
            If it does, then I could consider building this into Avi FourCC Fix.

            Tested that method and works beautifully for me as well. Although in al fairness I’m testing with almost the same setup, Mac with ffmpeg version 2.8.1. Would be really nice to have this build into your FourCC program.

            Do you have any large recordings? Just to see how slow conversion would be. Right now we’ve tested a small file, and on my MBP the conversion is very fast, so I have no clue about timing with larger recordings.

            hans

          • Apr 5, 2016 - 6:48 AM - Quassum Comment Link

            I believe the maximum is 15 minutes, just a regular recording without movement?

            Would be nice to test:

                1) ffmpeg -i YourFoscam.avi -c:v copy YourFoscamWithAudioConverted.avi

                2) Apply “Fix MP4 (new)” in “Avi FourCC Fix” on the “YourFoscamWithAudioConverted.avi“

            And see how “well” this trick works on longer recordings – I do not need such a recording myself of course.
            Just wanted to know how “bad” things get, and if the result is acceptable, then I could include this in AVI FourCC Fix …

            Yup works perfect, ffmpeg command takes only 3 seconds on a 10 minute file here and “Fix MP4 (new)” is instant of course.

      No problem John 

      I just tested ffprobe under Windows and it basically says the same:

      [avi @ 02ea0d40] Could not find codec parameters for stream 1 (Audio: none ([38][247][0][0] / 0xF726), 8000 Hz, 1 channels, 8 kb/s): unknown codec

      Which means that audio under Windows appears to be working coincidentally? I might be concluding the wrong thing here, but if ffprobe cannot even find a codec, then I just assume that the stream has no [proper] codec definition.

      Note

      1) I examined the file with GSpot as well, which returns the same result for the Audio codec (0xf726(unknown)). GSpot also indicates under Windows that the “codec” is installed and that the audio is 8000Hz 8 kb/s (1 channel). 

      2) Playback under Windows and Mac OS X, using VLC, indicates that there is either no supporting codec (original) or only one strea, (altered file). In the altered file only 4 bytes have been changed for the video codec FourCC, so the Audio stream is unaltered. Windows Media Player does still produce Audio when playing the altered file.

      3) The FourCC Changer (only available for Windows, not from Tweaking4All.com) does not seem to be able to “fix” this either.

      4) Other codec detection tools return the same result … oddly enough.

        Thank you so much for trying.  It’s so frustrating to see QNAP releasing such a wonderful surveillance system only to find out that you can only properly use it on a PC.  On top of that, there’s not a easy way to convert these files for viewing on iPads.  I’ve tried Synology’s system.  The clips work right out of the box on both Mac and PC VLC.  The only downside is the UI, which I find quite confusing to use.  I hope one day QNAP just sticks with the common codecs to save everyone time and effort.

        Couldn’t agree more … it’s sooooo unnecessary to have crippled AVI files – as you can see with both the MPEG and H264 video codecs, changing 4 bytes fixes it. Shame on QNAP for that … not to mention the ridiculous license price for each camera we’d like to use.

    I was looking for this fix in The Internet for a while now. This solve my problem with qotdoor Ip camera called ‘coolcam nip-06’ and qnap server. I thought I would never find fix to this.

    I appreciate Your work toward making Linux version of video decoder.

      Hi Peter,

      I do not have an NVR, but I’ll just carefully assume it’s a QNAP NAS variant.

      Could it be that your QNAP is removing old highres recordings for space (see if you can find the actual file on your QNAP).
      Or maybe it didn’t record highres to begin with?

      I’m just guessing …

    Hi Guys,

    I followed every steps but doesn’t work for me. VLC continues to show up qIVC error.

    Do you have any suggestion?

      Did you try option 1: Avi FourCC Fix, or Option2: Converting?

      If you still get the qIVC error, then something went wrong, as that FourCC code should not appear in the “new” file at all.
      I created Avi FourCC Fix for that purpose. I actually replaces the FourCC code with a valid one.

      Since you have the iQVC error, in the latest version of Avi FourCC Fix (1.1), simply click the “Fix MJPEG (old)” button after you’ve added the file(s).

      As far as I could find info, QV6K is an MPEG4 variant? But what kind of MPEG4 variant?

      I do not have any sample avi’s in that format to test with.
      Did you try replacing “qv6k” with “h264” ? You can type the text “Current” and “New” fields.
      If that didn’t work, try “QV6K” and “h264“? I’ve seen it spelled in all caps elsewhere.

      Or if you can provide a short example file, then I’d be more than happy to test …

        Hi Hans ,

        Thanks. I have both type of recordings , in capitals and without . When I type it in manually and I choose MP4V it works but i loose the audio.

        I have tried others, without any success so far. Im happy with this , great program, but would love to have audio too. 

        Thanks !

        Cool, so did you replace the “QV6K” or the “qv6k” with “MP4V”?

        I’d have to analyze a video sample to know what’s happening to the Audio.
        Any idea where I can get a short example AVI?
