Try not changing audio sample rate; delete 'samplerate=8000'.

Subject: [vlc-devel] codec/encoding settings request


We are currently using VLC as the mainstream video player for a corporate IPTV 
broadcast in SD, with 9000 users. In general, people are very satisfied with the 
overall system, especially with the CPU utilization being order of magnitude 
lower than the MS counterpart (which makes a lot of people delighted here).. 

However, there are a few issues like lipsync, pixellation, and interlace, which 
begin 1-2 hours after the encoder starts. The customer is just restarting the 
encoder (vlc 1.1.7) every time they detect a problem and that fixes the issue 
for some more time. I was wondering if there is a known issue with the 
particular codec they are using.. and if someone could recommend a better 
codec/setting to give a try, that would be definitely worth testing.

Here are the encoder settings:

C:\Program Files\VideoLAN\VLC>"C:\Program Files\VideoLAN\VLC\vlc.exe" dshow://
 :dshow-vdev="Osprey-210 Video Device 1" :dshow-adev="Osprey-210 Audio Device 
1L" :dshow-caching=600 :dshow-vdev= :dshow-adev= :dshow-size= 

 :dshow-chroma= :dshow-fps=0 :no-dshow-config :no-dshow-tuner 
:dshow-tuner-channel=0 :dshow-tuner-country=0 :dshow-tuner-input=0 

:dshow-video-output=-1 :dshow-audio-input=-1 :dshow-audio-output=-1 
:dshow-amtuner-mode=1 :dshow-audio-channels=0 :dshow-audio-samplerate=0 
:dshow-audio-bitspersample=0 :dshow-caching=600 


Kindest regards,
