I have a H264 video source that was recorded with variable framerate (VFR) and a text file with frame ID, timestamp pairs that looks like this:
frameId,timestamp 1890413473,13792093 1890413474,13792106 1890413475,13792123 1890413476,13792139 ...
If I try to playback as is, it defaults to the 25 constant framerate (CFR)
ffmpeg -i stream.h264 -c copy stream.mkv
How do I combine the timestamp data to make a .mkv playing at the appropriate rate? The docs have
-vsync vfr which looks related, but not sure about the input format for the times to sync with.
