Though my published versions of gmplay (posted in the first post) allow video to lag up to a full second to prevent visible frame drops when eink updates take a lot longer than usual, for audio sync I plan to always display the most recent frame (allowing only up to a single frame delay before frame dropping). In essence, I will display the video frame that most closely matches the audio being played, within that 170msec time window. With video frames presented 130msec apart, it will be easy to choose which frame to display even assuming that the frame could take longer than normal to become visible on the eink display. All good, so my previous worries can be put to rest.

Now the problem is how to get ALSA sound compiles working again on my new build system. Missing dependencies to figure out...
