You're right about a lot going on behind the scenes with the Mirasol video player. I've now had a chance to play with a variety of video sources and now suspect the issue with video stall may well be related to some sort of garbage collection procedure. Almost all Mirasol video tends to stall about 1 1/2 to 2 1/2 minutes in. If one leaves it to resolve it's issues, it will studder in a failing restart situation for a minute or so and eventually start playing video again. It then runs for about another 30 or so seconds when it goes back into studder restart mode. Studder mode this time takes longer to resolve and when video does restart it runs for much less time before doing a slight studder. This can go on for a few iterations until it evenutally goes back into a more endurable studder mode. Endurable studder modes are not endless but can take 2 or 3 minutes to resolve. The duration of whatever fix gets accomplished during this mode appears to have less and less durability but that might be more related to the video that needs to be digested rather than a steady deterioration of the amount of available resources that initiates the interupt procedure. Halting video playback and moving the video position slider back about 10 seconds will restart the video immediately and allow it to run for another 45 seconds or so. If left alone the video player just stays in studder restart mode where it appears to decode about 10 seconds worth of video after which it gets interrupted and restarts decoding. The above cycle appears to be endless but it isn't. As previously noted, this mode appears to take a few solid minutes to become resolved. I get the feeling it's all related to some sort of interrupt that is just not getting well enough resolved via the chosen actions. Memory garbage collection would fit into that scenario and be easily resolvable by the addition of extra video (?) memory. However, that might well be a line in the sand which has become non negotiable due to pricing.
