I was told to make mp4 files. I did, but now at the client I find out
that the format is wrong.
My files have the following format:
Stream #0.0(und): Video: mpeg4, yuv420p, 1028x795 [PAR 1:1 DAR 1028:795], 1085 kb/s, 15 fps, 15 tbr, 15 tbn, 15 tbc
but what they need is:
Stream #0.0(eng): Video: h264 (High), yuv420p, 640x480 [PAR 1:1 DAR 4:3], 30 kb/s, 10 fps, 10 tbr, 10k tbn, 20 tbc
I tried several things, but until now with no avail.
I tried for example:
ffmpeg -i afspraak.mp4 -vcodec copy -vbsf h264_mp4toannexb -an of.h264
Which gives:
Output #0, h264, to 'of.h264':

Does anyone have a pointer for me where to find the info I need?
