When using mpv
to step through frames (.
for stepping forward and ,
for stepping backward), the forward stepping rate is much faster than the backward stepping rate. The forward rate is about the same as the video frame rate (60fps for the video in question, which is an mp4 file prepared from a set of png images using ffmpeg
with libx264
encoding) whereas the reverse stepping rate is about 1fps. Is there any way to control the stepping rates? Why would the forward/backward rates be so asymmetric? If an alternative video player is available for linux systems that supports variable (or at least equally fast) video frame stepping, please advise (mplayer
is not better than mpv
in this regard).

That seems to be a codec problem. From https://github.com/mpv-player/mpv/issues/4019:
According to that bug-report choosing the mjpeg codec should be faster, but I cannot confirm this.
