Trouble with HEVC playback

Post by KennyB »

I have been having lots of trouble with HEVC playback in the "Videos" section. Somedays it will work fine, and my files will play, but other times it will simply crash Mythfrontend and the logs aren't really very revealing of much except that it usually has something to do with ALSA. In fact, the only time it does work is when I select PulseAudio from the audio menu despite the fact that PulseAudio:ALSA or ALSA:pulse works for every other format. But then randomly today, it stopped working even with just PulseAudio selected.

The only difference I can tell between then and now is that my disks are really busy hash-checking some stuff right now, whereas yesterday they weren't being used. The other thing is I use a program called mhddfs that merges several volumes into one mount point, but the disc speeds are very low, like 4 MB/s max. Is it possible the low disc speed is causing HEVC playback to fail?

The only reason I doubt that possibility is because VLC is playing the same files without ANY problems whatsoever even with the disks being maxed out.

I'm on Ubuntu 18.04 but this is happening on Mint 19.1 and Ubuntu 16.04 as well. MythTV version is 0.30

When running mythfrontend with debug loglevel, this is all I see in the terminal window as it tries to play

Edit:

I can also confirm that Mythling ( Android MythTV frontend) has no issues playing the files that Mythfrontend seems to be crashing on.

I decided to try with 0.31 from Mythbuntu PPA and fresh install of Mint 19.1, and I'm still getting the behavior. Though I did get a bit more of an enlightening error from PulseAudio this time. Using OpenGL because that's what I normally use for HEVC stuff.
