[FFmpeg-devel] [PATCH] avformat/matroskadec.c: Fix support seek to non keyframes

[Seokjin Hong]

In previous commit from 7c00d853a65884870e2a7a916197d87c125ed630,
It looks like adjust skip_to_keyframe param to support seek to non
keyframes.

But this code seems to avoid adjust matroska->skip_to_keyframe param.
It always set to 1 without considering AVSEEK_FLAG_ANY flag.

I don't think this code is what you intended.

Please check this patch or explain the reason why matroska->skip_to_keyframe
is always set to 1.

Regards.
