I recorded USB webcam pictures with MJPG_streamer and converted them to mp4 using
ffmeg -r 20 -pattern_type glob -i "*.jpg" -c:v libx264 test.mp4
Firefox complains "video can't be played because the file is corrupt"
Google Chrome and VLC have no problems playing the file.
What options for ffmpeg do I need to create the mp4 files so that firefox can play them?
The firefox web console says:
could not be decoded, error: Error Code: NS_ERROR_DOM_MEDIA_DECODE_ERR (0x806e0004)
Details: RefPtr<MediaDataDecoder::DecodePromise> __cdecl mozilla::WMFMediaDataDecoder::ProcessError(HRESULT, const char *): MFTManager::Output(2):80004005
