Hi, I have an mp4 file, that I want to convert to Annex B. The file properties are: Duration: 01:59:59.97, start: 0.000000, bitrate: 1221 kb/s Stream #0:0(und): Video: h264 (Main) (avc1 / 0x31637661), yuvj420p(pc, bt470bg/bt470bg/smpte170m), 1280x720, 1221 kb/s, 15 fps, 15 tbr, 15360 tbn, 60 tbc (default) I am converting to Annex B this way: ffmpeg -i file.mp4 -vcodec copy -vbsf h264_mp4toannexb -an output_file.264 After running ffprobe on the output_file.264: Duration: N/A, bitrate: N/A Stream #0:0: Video: h264 (Main), yuvj420p(pc, bt470bg/bt470bg/smpte170m, progressive), 1280x720, 30 fps, 30 tbr, 1200k tbn, 60 tbc As you can see, the duration information has been lost and fps is now 30 fps. It it possible to retain the original FPS?
