MediaPortal Audio renderer - better video playback quality (1 Viewer)

[tourettes]

Using V14 atm, and working fine with video's, but when i use it with LiveTV, when switching from a HD channel with stereo; to HD channel with Dolby(5.1); nothing happens, when i change back to my normal output (SPDIF) all is working fine..

Logs? Also a TS recording that can be used to reproduce the issue under My Videos would help a lot.

If te multiplier is stable from the start (and wotn for example slide from 1.02 to the 1.002 during few minutes) I'll provide one test binary that has the infamous * / change

The multiplier is quite erratic. Change quickly from 1.0 to 1.04.... even less 0.95..0.96..

How long it took to settle down to the 1.002 area? Or was it luck that both screen shots show it as 1.002xxxxx? This could be related to the Xonar and corrupted audio in exclusive + event driven mode bug, both are related somehow to the buffer filling / events.

Others - please post the multiplier behavior from different audio HWs (logging it / reference clock behavior will create many megabytes in really short period - so I wouldn't want to fill the forum with such).

Event driven mode is off (WASAPIUseEventMode=0)
Anyway , yes it's a luck that both screen shots show it as 1.002xxxxx. the multiplier is always erratic . No change after 4000 frames.

AW: MediaPortal Audio renderer - better video playback quality

I need a delay of 100ms for my receiver. Is it possible to setup this? With SPDIF enabled in FFDSHOW i was able to do it in FFDSHOW config.

Currently no but maybe after bigger issues are solved such registry key could be added.

I know since Xonar drivers requires that to be used - but the point was that those issues could be caused by the same root cause, same bug in the drivers. Thats why I need some information from other types of HW and how the multiplier is behaving on their systems. If it is stable on other HW then it is most likely a driver side issue.

Anyway , yes it's a luck that both screen shots show it as 1.002xxxxx. the multiplier is always erratic . No change after 4000 frames.

Good that is random error, it would point more into the driver issue since the code should create more systematic error.

Here's a binary that will log the audio HW clock information that the driver provides. Please provide a log that shows the results.

Watched a two hours movie (25fps HD) and didn't experience any a/v sync problem with v14. Also TV seems to have no problems.

During the two hours movie I had 0 frame drops or late frame nor any visible stuttering.
