RE: Support Thread for MediaCodec - bac522 - 2014-02-14

Using the latest nightly build (as of this post xbmc-20140212-a74973f-master-armeabi-v7a.apk) when trying to play mpeg2 files recorded via Mythtv, XBMC crashes on my Minix G4 using mediacodec; it plays very slowly using libstagefright.

Playing the same file on my Nexus 7 works fine using mediacodec.

And a copy of my logcat

The file I was attempting to play was "pvr://recordings/Default/25_1 (WFXT DT)/"

Running mediainfo on the file shows:

Software:
CyanogenMod 10.2.1-encore

XBMC:
Gotham nightly 13.0-ALPHA12 20140218-f6f539a
Skin: Touched
MediaCodec enabled, Libstagefright enabled (thus uses MediaCodec)
All other settings default after a fresh installation.

Log:
http://xbmclogs.com/show.php?id=135210

Steps:
Start XBMC
Select Videos>Files>sdcard1>Downloads
Play "Fun.- We Are Young.mp4"

Problem:
Spinner appears, never stops spinning, video never starts

If I disable both libstagefright and mediacodec, I can actually start playing any of my media files (though on anything greater than SD it grinds to a halt shortly). I can't see obvious errors in the log, but you can see the timestamp jump at the end -- it never really 'starts'. I'd love a "this will start working soon" answer, but will settle for a "this will never work because XYZ" (e.g. OMAP3 never going to be supported, or Huh)

RE: Support Thread for MediaCodec - gotpaste - 2014-02-28

Is there a way to default certain codecs to mediacodec and others to libstagefright. I have to constantly turn off and back on mediacodec on my RK3188 device. I used to run the 9/29 version of Gotham and never had any issues but anything after this I have to turn off and on mediacodec depending on the show I am watching. It would be great if I could update a file so when a particular codec is needed it defaults to the correct setting.

Since this PR https://github.com/xbmc/xbmc/pull/4524 was merged I can't watch properly any video using Mediacodec. It looks like this:

Yeah, bogus commit. It will be reverted soon.

RE: Support Thread for MediaCodec - Koying - 2014-04-16

Dears,

We have found a rarely occurring bug in MediaCodec and would like to be sure the fix doesn't break anything.
Could you test this Gotham master build, please: http://mirrors.xbmc.org/test-builds/android/arm/xbmc-20140416-3224eca-fixamcreleasebuffer-armeabi-v7a.apk

Thanks

RE: Support Thread for MediaCodec - Kib - 2014-04-16

@Koying

I did some testing with my Nexus 5 running Android 4.4.2 but it seems mediacodec is completely broken with both builds.
https://docs.google.com/spreadsheets/d/1kXGDCLxj4DrdvbIUs2-0bOCg2zKWl_GgQ5EWt9v2mrE/edit?usp=sharing

If you want a specific log etc I'll be glad to assist.

RE: Support Thread for MediaCodec - althekiller - 2014-04-16

Seems OK with Dalvik. ART is not a problem for Gotham.

Tested my dir of samples with B3 and the PR build, no noticeable difference AFAICT.

RE: Support Thread for MediaCodec - natethomas - 2014-04-17

That may have done it for me, koying. Otoh, I wasn't able to install the apk at all until I had uninstalled the old apk, so for me it may have just been a crap install or something.

Re: Support Thread for MediaCodec - Koying - 2014-04-17

@Kib
Could you take a logcat while MediaCodec is cashing?
Are you using the stock FW?

@Al
Do you mean you tested Gotham with ART and you had no issues?

RE: Support Thread for MediaCodec - Kib - 2014-04-17

@Koying Yes I should be able to do that. Edit: when I am back home in about 10 hours from now.

As far as I understand from team chatlog from yesterday, althekiller tested with dalvik which was working then switched to ART and confirmed breakage

Note: When installing the pr build on top of nightly android will ask if you want to update, then error out with 'app does not exist'. I believe this is what Nate saw as well. Probably something to do with version numbering - I dismissed it as being not important

Re: Support Thread for MediaCodec - Koying - 2014-04-17

Hehe... So you mean exactly the contrary of what he wrote ;-)
No having any ART device myself (are there other than N5 currently, officially?) , it will be quite difficult for me to fix, but having a logcat might give us an idea.

[edit]
Oh, maybe he meant that ART having a problem is not a problem for Gotham.

RE: Support Thread for MediaCodec - Kib - 2014-04-17

Every 4.4+ device supports ART.
Hardware accelerated playback in MXplayer works for all my testfiles (dts audio needs to be done with optional external mplayer dll, in software) under ART.

I think althekiller meant that ART being broken does not need to be fixed for Gotham.

Edit: indeed Smile
Edit2: I am new to testing android, but fully willing to invest some time. Adb logcat seems easy enough, probably could do debug traces as well.

Re: Support Thread for MediaCodec - Koying - 2014-04-17

Yep. And indeed KK boxes are coming (Minix X8 that I know of)...
