Description

Hello,

First I'd like to thank you guys for all the good work regarding TVHeadend.

I'm using transcoding in TVH for a while now and it always worked fine. Last weekend I updated TVH with the latest GIT version and it seems that the libx264 encoding is broken. No video is shown in VLC, only audio. When I select another video encoder, for example mpeg2video or libvpx, the video is displayed correctly. I tried both VLC on Windows and IPad, which always have been working. I'm using the Matroska (mkv) /built-in container for transcoding. The problem occurs on all resolutions.

I ran the configure script with these parameters: ./configure --prefix=/usr --disable-hdhomerun_client --enable-libffmpeg_static

The syslog shows:
