Blurry playback of lossless x264 video

[Ravefiend]

I'm unable to get VLC to play a lossless video accurately. Instead, playing the video using VLC 2.2.2 it's showing a blurry video.

Creating the video:

Code: Select all

ffmpeg -y -f dshow -i video="screen-capture-recorder" -video_size 1920x1080 -c:v libx264 -preset ultrafast -qp 0 capture.mkv

The option -qp 0 is to be considered as 'lossless' for the x264 codec. I'm using the latest ffmpeg static (N-79056-gd0a9114) for recording it.

If I play this video full screen using another player, even Google Chrome, it is shown as pixel-perfect, but not when playing it via VLC. Why isn't VLC able to play the video in the same way?

Edit: tested with vlc-3.0.0-git-20160316-0401 and the problem does not replicate on that so it appears that somewhere down the road, this is already fixed.

Seems it may be the same problem as in my thread: https://forum.videolan.org/viewtopic.php?f=14&t=131107

I was testing that with recording terminal fonts ( should be sharp ) and source is good, but playback is blurry and dark. That problem is also in 3.0.0 but a little less visible.

Without any problem plays that file PotPlayer, SM Player and TOK Player, so it has to be something with VLC. I tried all options ( of x264 and other ) but with no effect.
