So I'm guessing that DRM may not be waiting the appropriate amount of time or something. This is why I need the timestamp information in your logs.
these are all cases with the patch.
With the DRM timing, the sample playback is crap.
With openGL timing enabled via playback setup, it looks a little
better, but still a lot of issues.
With Usleep and wait timing (the result of changing the code you
suggested), playback looks great!
here are 3 log files for the case above. (on my dropbox as pastebin
was throwing an error)
Is there any way to disable the DRM timing method (or enable the
Usleep one) without modifying the code?
Are you going to submit this patch for possible inclusion upstream?
it makes unwatchable recordings watchable for me. I appreciate your
effort, and time.
