Hardware Decoding on CUBE U9GT2 Tablet?

[coolbix]

I enabled the hardware decoding option on the CUBE U9GT2 tablet which uses the RK2819 processor.
Upon playing a video, the screen is filled up with the green color and VLC goes down few seconds later.
Has anybody succeeded enabling the hardware decoding on U9GT2? Can anybody please give me a clue to fix it?
I've attached the log.

By the way, the omx accessing mechanism is one of the key features of the VLC-android, I think.
The guy(s) who wrote the omx part (omxil.c) did excellent job. Great idea and Nicely done. Much appreciation!

Hi,

I haven't heard about this chipset before at all. Not sure whether this really has a hardware decoder at all - even if it uses OMX.rk.video_decoder instead of OMX.google.h264.decoder, it still seems to end up using "On2_AvcDecoder" internally, which is the software h264 decoder within the android media framework. (Log prints of playing back h264 with the stock media player might give clues to one direction or the other about this.)

Or perhaps it has a fallback internally for h264 variants the hw decoder doesn't support, so that it would use the hw decoder for other files?

Or you could try make it skip the OMX.rk.video_decoder component (so that it would try OMX.rk.video_decoder.avc instead) - not sure if that helps or not...

Thank you for the kind response.

I'm sure that it has a hardware decoder, because I can play a 720p video smoothly by the stock player (and some other player from Market, such as MX Player).

According to the log, it seems to use "On2_AvcDecoder".
However, I don't think that it is the software decoder in this case.
I've tried the stock player. The log from the stock player tells the same thing, "On2_AvcDecoder".
I may guess that the OMX.rk programmer uses the PV software decoder as a template for their hardware decoder plugin.

I've tried "OMX.rk.video_decoder.avc" instead of "OMX.rk.video_decoder".
The result is the same. (still green screen and crash).

I've played the same video file on Nexus S by the VLC-android.
It plays very good.
Here are major difference of the log between Nexus S and U9GT2.

[log from U9GT2]

D/VLC ( 2012): -> video H264 - MPEG-4 AVC (part 10) 1280x720@29.97 (7,0) (0,0) (0,0,1280,720)

[log from Nexus S]

D/VLC ( 2012): -> video H264 - MPEG-4 AVC (part 10) 1280x720@29.97 (7,0) (1280,720) (0,0,1280,720)

Couldn't this diffenece be any clues?

Sincerely,

Ok, so it's definitely possible that the traces pointing to On2_AvcDecoder only are a red herring and doesn't mean it wouldn't use hardware anyway.

Unfortunately, I don't have any other ideas off-hand at the moment - this particular decoder might require us to use other kinds of buffers (android gralloc buffers) which I haven't yet investigated how to use (not sure if it's possible from normal client applications) or if there's some other issue. However, if you say that it works with other apps such as MX Player, it might either be some setting that we're missing, or then they simply integrate into the media framework at a higher level (which makes it work for them), but which might not be usable for VLC (since it would mean giving up most of the rest of the VLC internal infrastructure).
