Some files not only use rounded timestamps, but they also do it incorrectly. They may jitter between up to 4 specific frame durations. In this case, I found a file that mostly used 41ms and 42ms, but also had 40ms and 43ms outliers (often but not always following each other). This breaks the assumption of the framerate estimation code that the frame duration can deviate up to 1ms. If it jitters around 4 possible frame durations, the maximum deviation is 3ms. Increase it accordingly. The change might make playback of "true VFR" video via display-sync mode worse, but it's not like it was particularly good in the first place. Also, the check whether to usen the container FPS needs to be stricter. In the worst case, num_dur is 1, which doesn't really indicate any evidence that the framerate is correct. Only if there are "enough" frames the deviation check will become meaningful. 16 is an arbitrary value that has been designated "enough" by myself. Also otuput the frame duration values for --dump-stats. |
