Comment 0 for bug 1443856

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 (?).
