[vlc] VLC dshow issues under 0.7.2 through 0.8.1

[steven wagner]

Hi VLC users (and devs).  I seem to be having some issues with the dshow 
access plugin while streaming from a WinTV PVR 250 on Win2k Professional with 
Directx 9.0c.  And before you ask, running Linux on it was my first choice but 
I couldn't get a stable MPEG-2 stream locally out of any of the ivtv versions 
I tried.

So:

Under the packaged Win32 version of 0.7.2, my dshow source works just fine the 
first time I run VLC, whether I'm streaming the card output via UDP/RTP 
multicast (the ultimate goal) or displaying it locally.  If I click Stop/Play, 
however, I get no audio.

The audio in question should be coming directly out of the PVR card, although 
I tried switching the audio source to a SBLive! card and basically had the 
same problem.

0.8.1 is a "good news / bad news" situation.  On the one hand, clicking 
Stop/Play now seems to work properly, and subsequent playbacks have audio. 
However, streaming and local output is filled with garbage.  The audio drops 
out frequently (between two and ten times per second) and a coherent picture 
doesn't fully form (the upper third of the picture, usually).

0.8.0 seems to combine the worst behavior of both versions.  Ruh roh!

In all cases the video signal is SMPTE color bars and tone - a static test 
pattern, in other words - and VLC is run with the following command line:

"C:\Program Files\VideoLAN\VLC\vlc.exe" dshow:// :dshow-vdev="Hauppauge WinTV 
PVR PCI II Capture" :dshow-adev="" :no-dshow-config 
:sout=#duplicate{dst=std{access=udp,mux=ts,url=224.16.32.48:1241,sap,sdp=http://well.lucasdigital.com:8080/video}} 
--ttl 12 -vvv

(for streaming, obviously)

For local display, the dshow input is chosen with no further options being set.

The only configuration of the Hauppage card being done on each boot is 
changing the tuner to the Composite input.

Here's what the logging interface module had to say during a local playback 
attempt on 0.8.1:

[... etc. ...]

Windows programming isn't exactly my forte, and at this point I'm almost 
tempted to try to get the ivtv driver working one more time... but if anyone 
has any ideas (or patches?  :D ), please let me know.

Thanks!
