Have tried Ffmpeg as above and many other converters as well as vlc and many other video players and editors.

It definitely contains both video and audio.ĭoes anyone have any advice on how to convert these files - I suspect that millions of people have these cameras (mine is made or oem'd by Golbong but I suspect others are using this format too judging by a bit of googling). Just change the audio codec to mp3 (what ever the original codec was) ffmpeg -i input.avi -vcodec copy -acodec mp3 out.avi. Copy the video and audio streams as well as the selected subtitle stream. copies the audio stream without any re-encoding. Use ffprobe to list the subtitle streams in the video.

What I think is going on here is that the format they are using is proprietary (I read somewhere that this could be to avoid licence fees). I want to convert a raw files to mp4 video format using ffmpeg and i want to. Output file #0 does not contain any stream rtsp Download a video file from a web site and convert it to audio or video. Stream #0: not enough frames to estimate rate consider increasing probesize Number of reference frames on output for ffmpeg-qsv is 3 These encoders only. Format h264 detected only with low score of 1, misdetection possible! The following shows the command and relevant output:įfmpeg -i atest.h264 -c:a copy -vn -sn ffatest.m4a I tried the solution above but the audio extraction doesn't work and I get lots of error messages and no output file. I then discovered ffmpeg and found I could convert these files usingįfmpeg -r 12 -i atest.h264 -c copy ffatest.mp4 I also really need a way of batching the conversion of all the files which I am sending to an ftp server. videoconver lacks any documentation and delivers video which runs at double speed.

h264 and until recently, the only way I had found to convert them to a format I could play on Windows was using software they supplied (videoconver.exe) to convert to mp4 (video and sound).

The camera records files with the extension. This command copies the video stream from input.webm into output.mkv and encodes the Vorbis audio stream into a FLAC. FFmpeg can help with this situation: ffmpeg -i input.webm -c:v copy -c:a flac output.mkv. Hi, I am trying to convert files from a Chinese manufactured birdbox camera which also has a microphone. It can be very time consuming to re-encode the correct stream.
