#8500: more accurate audio timestamps
-----------------------------------+----------------------------------------
Reporter: markspieth | Owner: jyavenard
Type: patch | Status: new
Priority: minor | Milestone: unknown
Component: MythTV - Audio Output | Version: Trunk Head
Severity: medium | Mlocked: 0

Comment(by jyavenard):
The whole concept of the lockless audio framework was that timecode would
be calculated in one thread only, not two (read and write). It's the
reason why SetAudioTime was removed
this patch breaks that, without having any of the required lock.
There is no need to increase the size of the audio buffer by a factor of
2, it will only cause seeking delays. Where does that requirement of 2.6s
delay comes from?
yes, there is a "race" in audiotime calc, but the worst case error is
negligible.
Will try to implement your timecode calculation cleanly and neatly soon.
