GPU video acceleration made possible by Apple?

Anybody know what's this error mean? I cannot get VDADecoder work.

Thanks

Open - VDADecoder Codec failed to open, status(-12470), profile(100), level(41)

More info needed, mediainfo on the file you are trying to play for example.

Noodle can you provide hardware info of your mac? Is it a 24" Imac with Geforce GT130? I have the same problem.

Noodle, mayday?

I have to say, it works on the new Mac Mini. Though i do experience some dropped frames, was watching Aliens yesterday and 25 minutes in and 310 dropped frames, now i do think to know what a dropped frame is but i can not say i saw the droppage happening.

All in all, im glad to be back to a new Mini, the XBMC menu doesnt quite blow the fan like the old one did (reason enough for me to get rid of it). It stays deafeningly quiet (to me), in menu, 720 play, 1080 play, it works great. I have to say, 1080 play also worked without the hardware acceleration, but the cpu regularly spiked over 100%(?) though then.

Also, back in the saddle regarding the nightly builds, i still remember (not always fondly) the t3ch releases on my xbox.

I have to say, this not being the thread but it is worth mentioning anyway, the (Harmony) remote seems snappier on the nightly builds, still not as snappy as the Apple remote but still, snappier is better.

Thats great! Or is it? Should we get this?

Did not help the problem unfortunately. There is some indication that running XBMC in windowed mode resolved the framedrop and I'd like to see if that works for everyone before I start looking into why.

davilla Wrote:Let me clarify, bitrate means squat. It's h.264 profile, level and reference frames that matters. At this time we know B,M,MP@L4.1 is fine, L5.1 seems fine, not explored the profile limits. Seems to not like 16 reference frames but still looking into that.

I'm sorry to be dense, but I'm finding myself completely unable to figure out the magic incantation to re-encode an Xvid to a h264 that works with VDAdecoder. The quoted section above is as close as I am able to find with any information about what VDAdecoder will accept.

At this moment I am using the Aug 18 nightly build, r32894M. I have "Hardware Acceleration" checked. I'm on MacOS X 10.6.4 (with the recent graphics software update). I'm on a Mac Mini 3,1 ("Early 2009") with 3GB RAM/256MB video mem.

I am trying to re-encode from Xvid to h264 with HandBrakeCLI. I was using 0.9.3 (I think) and have just bumped to the most recent nightly build in order to get the latest bundled x264 library.

I have tried every possible variation I can think of to re-encode the video, but XBMC consistently reports the the dc is "ff-h264". Testing with some of the videos posted here gets me "vda-h264" so I know that, in thwory, I should be able to use the VDA system.

How I'm trying to re-encode the video (the "iPad" preset is new in the HandBrakeCLI, but I had the same results with older CLI versions with other presets):

~/apps/HandBrakeCLI -i test.avi -Z "iPad" -e x264 -x level=4.1 -5 -a 1,1 -E ac3,faac -B auto,160 -6 auto,dpl2 -R auto,auto -o test.m4v

This produces a file that has this MediaInfo video profile:


So - what am I doing wrong? I have spent more hours than I care to admit trying to chase this down over the last two days. I'd very much appreciate a pointer to information about what magic incantation I need.

Thanks!

Nothing you do will enabled VDA decoder on SD sized videos. VDA decoder is coded in XBMC to be used with HD content.
