For the source you're playing, frame interval should match the refresh rate.
That's a good question. As I had not noticed this previously in the logs, I
ran another test this morning just to be 100% certain that I had not grabbed
the log while I was playing around with the time stretch settings. I
confirmed that this message is repeated:
2008-07-31 08:40:54.184 NVP: ClearAfterSeek(0)
2008-07-31 08:40:54.186 NVP: Changing speed to 0.45
-> threshhold(64 KB) min read(0 KB) blk size(32 KB)
2008-07-31 08:40:54.187 NVP: DoPlay: rate: 59.9401 speed: 0.45 skip: 1
=> new interval 37074
2008-07-31 08:40:54.187 NVP: Stretch Factor 0.45, disable passthru
I made no changes to the playback settings (or timestretch), I simply
restarted mythfrontend and immediately played the video.
Is this the problem? Why would the stretch factor be getting set to this
I grabbed a log of the MythTV output playing a video that does not exhibit
this problem and you can view it by clicking the link below. After looking
through the log, I do not see the stretch factor/changing speed messages.
