Patch
x264 sometimes outputs keyframe DTS lower than PTS and DTS of next frame equal
to keyframe PTS. Videoencoder changes the keyframe DTS to PTS, which results in
non-monotonous DTS causing decoding problems.
Also x264 outputs following timestamps
Frame1: PTS 0, DTS -66666666
Frame2: PTS: 20000000, DTS: 0
Videoencoder turns the first frame to PTS:0, DTS:0 so there are two frames with
same DTS resulting in muxer warning
