According to GSpot, LAV Video doesn't have "MEDIATYPE_DVD_ENCRYPTED_PACK", which apparently is required by MPC-HC for connecting an MPEG-2 decoder to Windows XP's DVD Navigator. Is that intentional?

But it does have it. If it seems missing, then re-register a recent version, in case you just overwrote it without registering.

LAV Filters 0.54.1
Code:
LAV Splitter
- Improved seeking in MP4 files created by Windows Live Movie Maker

LAV Video
- Improved H.264 DXVA on recent Intel GPUs (Sandy/Ivy Bridge and newer Atoms)
  - Fixed corruption with high number of reference frames ( > 11 )
  - Fixed corruption in MBAFF interlaced content
- Fixed an issue that caused DVD menus/subtitles to stop working in DXVA2 Native mode in some situations
Download: Installer (both x86/x64) -- Zips: 32-bit & 64-bit

So, it appears Intel does actually support full spec compliant H.264 DXVA on Sandy Bridge/Ivy Bridge and newer Atoms (just a slightly different part of the spec which is not used by NVIDIA/AMD), my implementation just wasn't 100% spec compliant, but now it is, and decoding on those CPUs/GPUs is now much better.
This change should not affect older Intel GPUs, except that i also added some checks to properly fallback to software decoding if you try to play a file with more than 11 reference frames on an old Intel GPU (which doesn't support this properly).

Anyway, as always please report any issues, especially regressions.

nev, lavr has fixed the 8->2 channel mixing crash on x86_32 ( commit ), and I've confirmed that reverting "avr: disable 8 -> 2 optimized mixing on 32-bit because of a crash" and compiling lavf with latest FFmpeg (merged with your branch) won't result in crash any more, so it should be safe to re-enable those asms.

I know, i was the one that reported the crash to them in the first place.
Will be changed when i next update, probably for the next release, unless i need to do small fixes again.

Ok thanks.
Almost all ffmpeg based players/decoders fail.

Install it and it works now.


Since ffmpeg doesn't implement interlaced VP6, why not just disable it? Because I still wanna use lav video for progressive VP6.

The new AMD/ATi graphics driver's quality is really terrible.

Unified Catalyst 12.10 Win7x64 on Radeon HD5450M (HP TouchSmart TM2-2102tx) seems broken with DXVA2 MPEG2 VLD mode. With this driver, dxva2n only works with H.264 VLD...

Unfortunately this is the only CAT 12.x driver works for switchable graphics modes and changing built-in LCD panel's color settings instead of GPU's. All AMD packed CAT 12.x driver sets seem to provide Intel graphics driver 9.x, which is incompatible with the 1st-gen Core i3-380UM. Otherwise I have to roll it back to old CAT 11.12 ...

MS-DTV decoder supports DXVA1 MPEG2 iDCT / MC modes, so it still get partial MPEG2 acceleration with this decoder.

The funny thing is that MPEG2_VLD is listed in Open Video Decoder profiles.

Only UVD3.0 cards (HD6xxx and above) have MPEG2_VLD, which is not a secret in doom9, so what you see is common.

Hi nevcairiel,

do I misunderstand the readme?

Quote:
If multiple audio tracks match one language, the choice is based on the quality. The primary attribute here
is the number of channels, and after that the codec used. PCM and lossless codecs have a higher priority
then lossy codecs.


Should not the 5.1 track be selected instead of the stereo track in this case?

The "[default]" flag overrides quality based decisions, only the language is checked.

I thought so. Then the error is text in the readme, because the primary attribute is the default flag not the channel count.

The text is correct, the primary attribute for quality is the channel count, it just doesn't mention the default flag in the audio-specific part.

DVD playback is b0rked with Overlay Mixer in MPC on Win7 here. Problem seems to be caused by a wrongly guessed stride (720 instead of 768).

If I uncomment the two lines above this one, then playback is OK:
DbgLog((LOG_TRACE, 10, L"-> We did not get a stride request, using width %d for stride", pBIH->biWidth));

(PS, yes I know overlay should not really be used on win7, I was just testing various stuff)

Just for my curiosity, why Overlay should not be used ?
Before madVR 0.11, I used to use Overlay Mixer renderer, and it was working well.
