[WINDOWS][PATCH]Bitstream output of HD audio formats

Jimbo Ro · 2012-02-05 03:00

My issue of having to change the audio track is fixed. For some reason I had to manually set my desktop to 60 Hz via my advanced tab in my monitor section, otherwise the nVidia control panel would do so...but disable the HD audio formats from the HDMI audio tab.

This is great....for the first time ever I've seen Dolby Digital + light up on my receiver lol....and now no skips like I saw in the AE branch.

Hey meridius - AMD/ATI 6450 with HDMI Audio driver AMD 7.12.0.7705 dated 12/6/2011 - it's in the latest Catalyst package 12.1. Video driver ATI 8.930.0.00 dated 12/5/2011 from the same package.

Great playback and HDMI audio support - everything I've thrown at it has worked!

+1, I have the latest AMD 12.1 driver on my HTPC's too. Everything works great!

Nice patch, made into my build. I just have two movies with dts-ma so that's all I could test but one thing I noticed is that the audio packets are calculated to be of 170.67 ms duration in CDVDPlayerAudio:: DecodeFrame() because audioframe.size is 32768 (it is 2048 for dts core). The invalid duration can cause audio sync issues with drop/dupe packet sync method. I think the packet duration should be the same 10.67 ms for all (?) dts fomats because HD formats are "just" added on top of core so it seems logical that the duration is also the same (although I was unable to find any specs on this).

I use a patch to prevent mkv/dts stutter (ignoring dts timestamps) and that immediately failed. It only works correctly if I force the packet duration to be 10.67 ms for dts(-ma). I made the following small change in my build to correct this (although I am not sure if this is the right approach): https://github.com/a11599/xbmc/commit/11...6895912886

The problem is TrueHD, the video is extremely choppy! Unwatchable.
I tried checking and unchecking "Use a fullscreen window rather than true fullscreen"
Same result...
Any idea?

I have the same problem with one MKV, made with MakeMKV I think. The video is choppy and the audio goes out of synch. It happens only with this one file, everything else plays fine.

Daniela, thanks for the patch. You did what the XBMC devs should had done months ago: patch the current AE so it can bitstream HD audio and then start work on the new AE.
