Upgraded the server. New problem with LiveTV. Now, the video will freeze, but audio will continue. That hasn't happened before. Seems to lock up the anroid tv client, forcing a restart. Sometimes able to ESC and restart from the Channel Guide. In the attached ffmpeg log, the entire stream locked up at the end (8:18) and couldn't recover.
Also attaching server log.
More info: this may be irrelevant, but the "spinning circle" when trying to load a channel appears to often freeze as well. When it does, the next screen is the "Playback Error?" screen. Click NO and the spinning circle restarts, but is not able to make a connection to the channel. After no progress for >a minute, ESC to get back to the channel guide. Try again, same channel. Same spinning circle freeze. Click YES to Playback error, no system response. Total lockup, force reboot of android tv. That ffmpeg log is attached, too, as ffmpeg log 2-4 V2.
Also tested recording the same program "Sunday Morning". Playback displays freezing about every 10 seconds, freeze for ~5 seconds, then resume. That ffmpeg log is attached as ffmpeg log 2-4 V3.
Finally, you are correct, Luke. This HDHomerun, like 3 of the 4 models sold in the US does not provide hardware transcoding.
