GSpot also indicates under Windows that the “codec” is installed and that the audio is 8000Hz 8 kb/s (1 channel).Ģ) Playback under Windows and Mac OS X, using VLC, indicates that there is either no supporting codec (original) or only one strea, (altered file). 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 codec definition.ġ) I examined the file with GSpot as well, which returns the same result for the Audio codec (0xf726(unknown)). I just tested ffprobe under Windows and it basically says the same: Could not find codec parameters for stream 1 (Audio: none ( / 0xF726), 8000 Hz, 1 channels, 8 kb/s): unknown codec If it does, then I could consider building this into Avi FourCC Fix. Please try this and see if it work for you. I used ffmpeg 3.0, on a Mac, and playback with VLC.

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!ġ) ffmpeg -i YourFoscam.avi -c:v copy YourFoscamWithAudioConverted.aviĢ) Apply “ Fix MP4 (new)” in “Avi FourCC Fix” on the “ YourFoscamWithAudioConverted.avi“Īnd then you have, relatively quickly, a working AVI file! When using ffmpeg and copy the video anc convert the audio, we only endup with audio, however …Īfter doing this: ffmpeg -i Test_Tweaking4All_2.avi -c:v copy test3.avi I fear that there will be no way to make it playable without conversion. The audio track however, remains a weirdo. ffmpeg -i Test_Tweaking4All_2.avi -vb 750k test2.mp4 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. There are plenty other locations to find pre-compiled ffmpeg builds, some of them you can find on the ffmpeg downloads page.įor 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. MacOS X (intel, 32 and 64 bit) – Evermeet.cx.I did however find it rather confusing to find a pre-compiled versions for specific platforms. You can find ffmpeg for several platforms on the ffmpeg homepage.

The second option is to convert the QNAP Surveillance Video Recordings to a different format, and here the free ffmpeg is very helpful.
Option 2 – Convert the recording to a different Video Format
Note : QNAP got the annoying idea to request purchase of licenses for each camera connected to your QNAP.
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. Playback of QNAP Surveillance Video Recordings
