[vlc-devel] [BUG] VLC can't play mpegts file with PCR pid = 0x1fff

[Georgi Chorbadzhiyski]

I have a small mpegts file [1] (about 140k) that VLC can not play. mplayer, avplay,
xine are playing it just fine. I think the problem is that this stream has PCR_PID
set to 0x1fff (null pid). This is maybe strange but the stream is captured from
satellite and it seems to be working on all kinds of STBs (and software players
as mentioned above).

I have tested:

> VLC media player 1.2.0-git Twoflower (revision 1.1.0-pre1-6322-gcaa3434)

Relevant VLC log:
