b-frames in mp4

[smitha]

Hi,

When I save an mp4 file from my IP camera with encapsulation MP4 and codec mp4v, it is found that my mp4 files have b-frames in them. My application has an MPEG4 player which plays only the simple profile MPEG4 files, which contains no b-frames. Is there any method to get a Simple profile MPEG4 file using VLC? Any one please help.

Dear Smitha
you may re-transcode stream by vlc with flag --sout-ffmpeg-bframes 0

Code: Select all

vlc source.mp4 --sout-ffmpeg-bframes 0 --sout=#transcode{vcodec=mp4v,venc=ffmpeg,acodec=mp3}:standard{access=file,mux=mp4,dst=destinantion.mp4}

Also you may transcode not only files, but streams too. Modify source.mp4 and standard{...} and have fun
