Re-wrapping files in FFmpeg audio problem

[philofarnsworth]

Hi!
I'm currently trying to re-wrap H.264 .mov files using FFmpeg to Mpeg TS without transcoding. I'm basically just trying to copy the audio and video stream into a Mpeg Transport stream. I've gotten the video to copy over fine but the audio won't come over even though FFmpeg is saying that it is. The command I'm using is:

ffmpeg -i original.mov -vbsf h264_mp4toannexb -vcodec copy -acodec copy new.mpeg

Video comes over fine re-wrapped as .mpeg but the audio is either not present (media info corroborates this) or shows up as a 2kb Mpeg audio stream which is basically empty. Any ideas?

[Baldrick]

Any errors in the ffmpeg output?
What is the audio codec in the mov?

You could also try remux with tsmuxer(command line and gui).

[philofarnsworth]

No errors in the output. I'm waiting on another test to finish and i'll post the full output. Audio codec is PCM 48/16. Tried just a straight copy and re-encoding the audio to AAC to no avail.
I can't get tsmuxer to open on my mac. Would I want to run this on my .mov before trying to re-wrap the file?

[Baldrick]

Maybe try "-f mpegts new.ts" instead of new.mpeg

[philofarnsworth]

Tried -f mpegts with the same result. Here's the output log if this gives you any clues:

It's unorthodox, but if the audio stream is ffmpeg compatible, then opening the original video in Audacity will automatically strip the audio for you. From there you can save it off as anything you desire. I do it all the time with mp4's, mov's, and .ts files. Much easier than command line.

I'm using Windows though, with the Ffmpeg Import/export libraries, lame and other plugins.
Not sure how the Mac would handle it but it works fine for me.


Edit: I know it doesn't answer the instruction problem, I mention for convenience only.
