Comment:
It appears you have video hardware that plays 6 frames behind real time.
It seems to be a unique setup. I am not comfortable with making a change
that is specifically for one user.
Version 30 has a new sync method (AVSYNC2) that is selectable from
settings, as well as a new audio buffer setting, where you can increase
audio buffering if needed. I do not believe these will fix your problem,
but they may change things in a way that causes your patch to work
incorrectly.
Version 31 will include rewritten rendering code that is currently being
worked on, and that may further affect you. As MythTV developers, we have
no way of testing your patch with new versions.
Perhaps another approach may be to add a setting for "additional audio
sync" to the playback group feature. Could you setup your recordings so
that they go into a different playback group based on their frame rate?
Each program that you record will likely have the same framerate for all
recordings. The playback group on existing recordings can easily be
changed through the front end. This does have the problem that playback
group settings apply across all frontends, whereas this setting is likely
to be frontend specific.
