Not necessarily, but it can, yes. It can also reference data in succeeding

Apologies if this is an FAQ.
I have a video with a fixed frame rate of 59.940 fps. Some of my devices
don't cope with this very well. Thus, I'd like to convert the video to
one with exactly half the frame rate (29.970), but preferably without

Thanks,
Yes I meant h264_mp4toannexb sorry for that.

This filter is called "h264_mp4toannexb" (note the last letter). In
recent ffmpeg releases and with latest git, it is automatic
Hello,
Can anyone help with conversion from mp4 to ts.
ffmpeg -i input.mp4 -c copy -bsf:v h264_mp4toannex output.ts
outpu.ts plays fine in vlc etc. but output.ts isn't compatibilie with
hardware decoders. pcr is rare in output.ts.
