#2512: Live tv studders little bit
---------------------------------+------------------------------------------
Reporter: chris at christophm.de | Owner: ijr
Type: defect | Status: new
Priority: minor | Milestone: unknown
Component: mythtv | Version: 0.20
Severity: medium |
---------------------------------+------------------------------------------
After the update from 0.19 to 0.20 live tv startet to studder a little
bit. You see it good, while watching a news channel with this scrolling
texts. I changed nothing else, only updated mythtv to 0.20 rev 11281. The
mythtv playback settings, the nvidia driver settings are all the same. The
studder can be stopped, if live tv is paused for a few seconds.
In my frontend.log, there are the following messages again and again, that
could have something to do with that studder:
* NVP: Waiting for prebuffer.. 0 AAAAAAAAAAaAALAAAuAAAAAAAAAAAAA[[BR]]
* WriteAudio: buffer underrun[[BR]]
* AO: dropping back audio_buffer_unused[[BR]]
I attach the complete frontend.log.

UseVideoAsTimebase=on, big audio buffer=on, decoder=Default[[BR]]
