0003-lavc-reset-codec-on-receiving-packet-after-EOF-in-co.patch

A bug in ffmpeg >=3.4 causes the avdec_h264 gstreamer element to hang and not switch the pipeline to playing state.

There is a workaround available:

https://anonscm.debian.org/cgit/pkg-multimedia/ffmpeg.git/tree/debian/patches/0003-lavc-reset-codec-on-receiving-packet-after-EOF-in-co.patch

I will attach the patch to this bug report to prevent the patch to become unavailable when the link goes down.

I applied this patch manually to ffmpeg-3.4 via /etc/portage/patches and it worked for me.

that patch should be applied to ffmpeg-3.4.1 and 3.4 is gone -> closing
