Android - MKV VC-1 playback issues
#1
Hi guys

I have a kdlinks a300 and am having issues playing blu-ray rips in Kodi 15.2. All of my files were created with Make MKV, but I've noticed that the ones that are h.264 seem to play fine, while the ones that are WVC-1 stutter and artifact and play at a low frame rate - around 13 fps or so - making them unwatchable. The audio seems to work okay, but the video looks terrible. I'm able to play the VC-1 files in the stock video player that came pre-installed on the box at a normal frame rate, although there is periodic artifacting (though that could be the file itself, as some of the disks were not in pristine condition).

I've tried turning hardware acceleration off and on, messing with other playback settings both in Kodi and in the box's internal settings, but nothing seems to fix the issue. With debugging mode turned on, it says that the CPU is running at like 150%, but this is a new, quad-core box with 2GB of RAM, so it should be powerful enough.

I've also tried updating Kodi to the latest nightly build, but version 16 looks the same as what I was seeing in 15.2.

I've posted the debug log here:

Any help would be greatly appreciated!

Simple: You device doesn't seem to support VC1 accelerated playback via mediacodec, according to the log, so software decoding is used, and the device cannot keep pace.

It looks like a Hisilicon device, which needs the stock player for decent playback, afaik.

I have the same issue on an nvidia shield tv (which apparently supports hardware vc-1 decoding). Only way I can get vc-1 files to work are to turn off hardware decoding altogether but this is a PITA to do everytime I watch a vc-1 encoded file. (Using Nov 2 Jarvis nightly)

I emailed the kdlinks support guy, and he pointed me to this solution:

You can install a patch so that Kodi launches the built-in media player to play files, then returns to Kodi when you stop/exit the video. I haven't watched a whole movie with this, but I've tried it out and it seems to work - so you can still use Kodi to browse files and whatnot and just play them within a wrapper.
