I have several situations where the playback is really scatty

XBMC.log http://pastebin.com/h1c7jGZV
Media info http://pastebin.com/eVh3DK2S

Looking in the log there are cpullup errors and audio packets skipped or duplicatedCPU is at 49% and no significant dropped frame come on the OSD

I also noticed some errors with the AC3 audio (although the decoder Dolby Digital Light stays on)

Crystal HD Driver 3.6

I suggest turning off the fancy sync playback settings.

If I take the sync audio video flag it starts with lip sync issues and becomes unwatchable

I'll be away from my chd boxes for a few days so will not be able to do any testing till end of the week.

interceptor121 · 2010-09-25, 19:48

any news?

Not seeing any issue under bcm70012 or bcm70015. audio and video stay in sync for analog out. Can't test AC3 passthough as I don't have a compatible receiver and don't get enough in crystalhd donations to get one.

"If I take the sync audio video flag", that's not what xbmc.log says Smile

DEBUG: CDVDPlayerAudio:: synctype set to 1: skip/duplicate

"Sync Playback to display" is on.
A/V Sync Method:
There are three settings, "video clock (resample audio)", "video clock (drop/dupe audio)" and "Audio Clock". You are set to "video clock (drop/dupe audio)" which will cause audio drop/duplicate to stay in sync.

Turn "Sync Playback to display" off and retest using the sample please.

The log is with audio sync on if I take it off there are no messages about skipping or duplicated but still errors cpullup
I will post another log shortly but that is really it

This is the log no skips but cpull up errors

"DEBUG: CDVDPlayerAudio:: synctype set to 0: clock feedback"

This is the normal with none of the fancy audio/video sync methods.

"DEBUG: CPullupCorrection:" is NOT an error. Ignore it.

"WARNING: CDVDMessageQueue(video)::Get - asked for new data packet, with nothing available" This means vq is drained and there's nothing to feed video decoder. Could indicate a problem, would need to see what a/v and framedrop in Codec OSD show and also dmesg .

Well I can tell you in the GUI the Sync Audio Video is set to off so XBMC must have its own life??
I just double checked with Sync Video/Audio set to off I see the following in the log
11:23:37 T:53006336 M: 2801664 DEBUG: CDVDPlayerAudio:: synctype set to 0: clock feedback

That would explain why with the Sync Video/Audio set to off the playback is more jittery XBMC is actually synchronizing using the audio clock regardless

Should I open a ticket in Trac?

All looks fine here.

Let's start again. What exactly is the problem here ?

interceptor121 · 2010-09-26, 19:03

Scatty play back at times like the frames are coming with pauses
So no fluidity like the framerate was not constant
To be frank that also happens without loosing frames
