x265/HEVC is slow to seek with VLC 3.0.8 but not with MPC-HC
Posted: 04 Jan 2020 18:06
Hello,
On x265/HEVC videos, the seek is slow with VLC (more or less 2 seconds) but not with MPC-HC which is instantaneous.
Since a video is better than words, watch this :

I know that I can enable the "Fast Seek" option on VLC but it moves from keyframe to frame and I want frame accurate seeking.
Thanks for your help,
