VLC 1.1.1 - no video/sound for dvbt

Hi all,

I installed on Ubuntu Lucid, VLC 1.1.1-1~ppa1 from PPA named vlc for Christoph Korn : Christoph Korn; the previous version from that PPA was fine (actually, only problem was that the VLC icon got stuck in Gnome and would not go away and close vlc, after the program was closed - only way was to force quit the program).

This v. 1.1.1-1 closes properly, however: it connects to dvbt stick, retrieves channel information, and then instead of streaming, it just shows black screen.

I've put the -vvvv output here:

v1.0.6 working
http://slexy.org/view/s20eBbeKpT

v1.1.1 not working
http://slexy.org/view/s20BKjd53X

(both pastes will expire in a month)

Here are the mention of errors in these pastes:

but I'm not sure anything of substance is shown by grepping for 'error' :)


I was wandering if anyone had a similar problem with blank dvbt; and since I'm aware there is already VLC 1.2.0 in git - has this problem been maybe solved upstream?

Thanks,
Cheers!

I am not sure if this is an issue with VLC 1.1.1 or the corresponding DVB driver (since I didn't test the particular versions)

but VLC 1.1.2 with the latest DVB driver seems to work fine

discontinuity errors are correct - I had to adjust the antenna for this screenshot.

1.1.1 was very buggy regarding TS and DVB.

we also noticed that mplayer is not capable of playing back those streams properly. It's MPEG-4. While VLC 1.1.2 (64 bit) is okay with it.
