[vlc-devel] Core i7 + FFMPEG MT bug related to invalid ES_OUT_SET_PCR calls

[Denis Charmet]

Hi,

It looks like the  Core i7 - FFMPEG MT bug is actually a mkv bug and is
due to an invalid use of ES_OUT_SET_PCR.

The demux calls it for every key frame it sends to the decoder fifo.
When I look to other demuxes they seem to send the blocks with an
earlier timestamp than the block actually sent.
I tried this approach with this (quick and ugly patch to test) :
http://pastebin.com/xTeQnm5H and it seems to fix the problem. I also
tried the avformat demux way (sending the min ts of all the tracks) but
it seems to increase the problem (http://typx.dinauz.org/mkv.patch).

The tests seem to agree, this is the root of the problem. Now I need a
guru's help to really know how it should be called and if the bug is not
elsewhere.

Regards,
