Timestretch with AC3 passthru results in broken playback
Reported by: | anonymous | Owned by: | Isaac Richards |

Description
Playback breaks badly as soon as I try to activate timestretch while playing a video with 5.1 AC3 encoded audio, with digital passthru enabled. Sound output is badly stuttering or just digital noise, and video skips forward at high speed (even if timestretch factor < 1).
Playback log shows that video is skipping because A/V sync believes video is always behind audio, and no amount of dropped frames allows it to catch up.
Attached log from mythfrontend -v audio,playback.

Can we get a retest with .23? Things have changed significantly and this issue may have been resolved.

I am not the original reporter, but this behavior was exhibited for me in many versions prior to 0.23. After upgrading to .23-fixes, this seems to have resolved almost all of my timestretch w/digital audio issues I had seen. (note: I do see the occasional new isue related to timestretch of playback of digitial content, but I believe this to be a seperate issue related to the new code).
I obviously would defer to the original submitter of the ticket for further comment if it resolved their issue, but I figured it would help to let you know that my tests showed this issue to be resolved. I was assuming that since the original submitter is anonymous, you might not recieve timely feedback.

Closing as apparently fixed-- original submitter, if you think this is not the case, follow up on the dev list for a quick discussion and if we all agree it can be reopened.
