When I do the conversion, like this: ffmpeg -sameq -i empower06.eu -r 30 empower06.eu I get an output AVI that reports itself as 30 fps, but is actually still only 24 fps. Be aware that the frame rate of the output stream is increased through frame duplication. I used these options to convert to the H/empower06.eu4 format for HTML5 playback (I think it may help other guys with this problem in some way). ffmpeg -i empower06.eu -vcodec mpeg4 -acodec aac empower06.eu4 UPDATE. As @LordNeckbeard mentioned, the previous line will produce MPEG-4 Part 2 (back in that worked somehow, I don't remember/understand why). Re-sampling H video to reduce frame rate while maintaining high image quality. Incorrect frame rate in video (Xuggler + MPEG 4 + H) 0. Using ffmpeg to transcode/transmux HLS to RTMP for nginx simulcast not working. 0. A/V out of sync when using ffmpeg from mpeg-ts to dash. 0.

Be aware that the frame rate of the output stream is increased through frame duplication. If you want to input and output to have the same frame rate, then just provide the input frame rate. This example will set a frame rate of / (NTSC video): ffmpeg -framerate / -i input empower06.eu4 Alternatively, in this example, you could use ntsc instead of /, but don't use because that is not accurate or correct. See other frame rate aliases. I used these options to convert to the H/empower06.eu4 format for HTML5 playback (I think it may help other guys with this problem in some way). ffmpeg -i empower06.eu -vcodec mpeg4 -acodec aac empower06.eu4 UPDATE.

Apparently this was because the stream lacked any framerate information at all and this is ffmpeg's default framerate. ffmpeg -i filename will show you the expected FPS but will not calculate the true frame rate for a variable framerate video stream. ffprobe -count_frames is the only way I've found to explicitly count the frames (note, this is slow since it must read the whole file!). Divide its output by the number of seconds in the video to get the true FPS. Re-sampling H video to reduce frame rate while maintaining high image quality. Incorrect frame rate in video (Xuggler + MPEG 4 + H) 0. Using ffmpeg to transcode/transmux HLS to RTMP for nginx simulcast not working. 0. A/V out of sync when using ffmpeg from mpeg-ts to dash. 0. Every H frame starts with four or three bytes sequence header 0x00 0x00 0x01 or 0x00 0x00 0x00 0x The frame is an SPS frame if doing the AND operation with next byte after start headers is equal to 0x E.g. SPS frame 0x00 0x00 0x00 0x01 0x Summary changed from Demuxing raw h from mpegts (and mkv, mp4) fails. to Muxing raw h into mpegts (and mkv) fails.
