yet have to find a 1080p bitstream that works without freeze.crash or reboot somewhere @ playback but it's nice that you trying to debug this you should look @ the 18.01 build and the changes after it Smile

Btw where those 50 ms delay on screen rendering results with downscaling involved (1080p->720p) ?
Well, tried the 18.01 version and it doesn't work any better (on Monsters, at least -> freeze).

I've found some kind of patterns, though. All 1080p 4.1 I've tried with ReFrames = 5 do work (I didn't find one with > 5 in my lib). All < 5 basically crashes the vpu...
You can check the value of a given file with MediaInfo.



Correction, the pattern seem to be that full size frames, i.e. 1920x1080, vs. cropped frames, e.g. 1920x800, make the vpu crash.
Furthermore, there something strange in the logcat:
Code:
I/OMXCodec( 1851): [OMX.rk.video_decoder.avc] video dimensions are 1920 x 1080
I/        (  90): init done status 0
I/        (  90): Width 1920 Height 1088
I/        (  90): videoRange 0, matrixCoefficients 1

No idea where the 1088 come from

i wouldn't count on that you should first try to get the Zelda Medley (Film Framerate) stable as it is much lower complexity and the chances if it runs are good that anything else will be more stable overall Wink

and yes 1080 is mostly handled as 1088 but this especially for broadcast and blu-ray hardware encoder you will see that the bitstreams are 1088 but the 8 pixels aren't shown @ playback Smile

Tough what makes me curios about this 1 user here said he could playback this without problems with his finless rom based mk808 Sad

So here it is again and i please everyone with RK 3066 to test it and report results if it crashes or doesn't, the firmware you use and if it's HDMI out and which output resolution and screen refresh rate.

also you should maybe first fix the SD stride issue first (squished output) from non width MOD8 bitstreams by padding those additional pixels @ playback so the renderer/decoder thinks it's mod8/mod16 and not mod2 which he seems can't handle
