Public bug reported:
A very short video, such as 1 frame long, won't play in VLC. Nothing
will show up, even if the video is paused.
A 1-frame video can be useful for things like testing the performance of
different encoding settings. While it's possible that VLC (maybe
depending on vout display module) causes the appearance of a video to
change slightly so it's not directly comparable to display by other
software, the display of two VLC instances can generally be compared to
each other.
The 1-frame video can be converted to a different format, but sometimes
this is lossy.
A bit related, if a video is very slow, like 1 frame per second, it
won't show up for a while in VLC. It's possible VLC is trying to buffer
several frames before showing anything.
Maybe also related, I noticed in ffmpeg, which VLC uses for decoding,
that a filtergraph wasn't receiving frames until at least two frames had
a DTS that was before the PTS of the frame entering the filtergraph. So
it's possible VLC is not receiving frames from libav (?).
