tsMuxer "Invalid Frame" Error

[koberulz]

I created some MP4 files some time ago, with MeGUI. Created a .264 file with MeGUI and an AC3 file with Audacity, then muxed with the MP4 Muxer in MeGUI.

Trying to demux them with tsMuxer and I keep getting "Invalid H.264/AVC frame at position #######" errors. Not on all, but on a few. Why is this happening?

Bump.

maybe you have errors in some of the videos? maybe corrupted for whatever reason

You can try demuxing with something else such as ffmpeg, or mp4box . Do they report errors ?

[koberulz]

How does one demux using ffmpeg?

[poisondeathray]

ffmpeg -i input.mp4 -c:v copy -an output.h264

[koberulz]

Well, yeah. But if I wanted to extract the audio to an ac3 file as well? Is there a one-step way of doing that?

demux all streams mp4box. This is like "wildcard", so everything gets demuxed, including subs, attachments, etc.. You don't have to "guess" extension

MP4Box -raw * INPUT.mp4



or in ffmpeg use -map to specify streams . There is no "wildcard" in ffmpeg, but since you know you have AVC video ,and AC3 audio it should work

ffmpeg -i input.mp4 -map v:0 -c:v copy output.h264 -map a:0 -c:a copy output.ac3

Well, the ffmpeg demux seems to work. Not sure why it tripped up tsMuxer.
