You can use -show_frames and do a little parsing yourself or use -count_frames and the native framerate to calculate the duration. Since the correspondence seems so flexible then you'll have to do any final extraction yourself. Fun question btw, you might look at increasing verbosity during the ffmpeg run to get timestamp values as ffmpeg is choosing to duplicate/drop frames. Maybe combine this with ffrobe -show_frames to make your desired correspondence? | |

| Nov 18, 2014 at 21:41 | comment | added | dstob | ffprobe can give you the timestamp information from the mp4 video stream. Are you asking as if frames may be duplicated or dropped then what is the correspondence to the original mp4 timestamps? In that case I would explore increasing the verbosity settings to see if you can get the frame by frame during execution. Could you expand on what you mean by "timestamps associated with frames". | |

Please include the complete ffmpeg console output from your command.

As what? AFAIK jpeg has no such metadata. The EXIF timestamp is for capture time.
