The one definite advantage added with bitstream support is DTS-MA decoding. With no open-source decoder for DTS-MA, the only way to play this back in full quality is by using a commercial product (and/or it's included filters) or by sending the bitstream to a receiver for decoding. Other than that, it seems to come down to a personal preference for some to have the decoding done in the receiver.

Not just the ATI cards but also Nvidia HDMI audio on Geforce 9300/9400 motherboards!

I've got this funny feeling that we're very close!

@Albain/SamuriHL,

I'll be ready to test on my 9300 when the next beta is ready.

Cheers

Bitstreaming currently only works with TMT on the Xonar. Adding bitstreaming capabilities to ffdshow would allow you to use other DirectShow programs (MPC-HC, MediaPortal, GBPVR, etc) to bitstream TrueHD/DTS-HD.

Still have this really annoying bug with Fraps videos that's only fixed by using RGB output.

YV12:

YUV2:

RGB32:

RGB16:

NV12:

The strange edge on the right side is my main concern (as opposed to the banding).

Potentially any HDMI 1.3 audio card will be able to use the HD audio bitstream version of ffdshow, as long as the source files are decrypted.

@devs: I'm getting 186 errors when building ffdshow x64 rev3121 with MSVS 2008, all pointing to xvidcore. Does anybody else have the same problem?

EDIT: Another question. Now the only stuff that are built with GCC are ffmpeg, ffmpeg-mt, mplayer and x264. Is this going to stay this way?

tal.aloni · 31st October 2009, 18:09

XhmikosR. I don't have any problem, try to clean the solution.
thanks for your builds by the way, impressive speed (up time).

XhmikosR · 31st October 2009, 18:21

Did you try with rev3121? The problem is only with the x64 build of xvidcore. I always use /Rebuild to avoid any conflicts.

It would be much easier for me if I could find a way to automatically patch files. For example this patch which I use in order to use komisar's x64 GCC.
I use patch -i "ffdshow_makefile_inc.patch" and it does not work. It drives me crazy!

Thunderbolt8 · 31st October 2009, 18:27

got a H.264 capture here which shows video corruption with ffdshow (v3119). plays fine with coreavc though.

50mb sample: http://www.sendspace.com/file/qltp8n

XhmikosR · 31st October 2009, 18:38

@Thunderbolt8: your sample plays fine with libavcodec. But using ffmpeg-mt it indeed does not play right. Using ffdshow rev3121.

I have tested 3121 x86, I haven't tested x64.

XhmikosR · 31st October 2009, 19:52

Then, that's why you don't have any problems, like I don't, for the x86 build.

yup, you are right. seems like it play just about fluently for me with only using 1 core. but it would be nice if this problem could be forwarded to the developers in case similar stuff might occur in the future with higher bitrates, then I'd have a problem :S

apart from that there seems to be a problem with .mkv remuxing using eac3to here, but thats another story.

Hi. I have troubles with decoding this AC3 file using libavcodec in ffdshow. The audio is distorted... Have no troubles with it using MPC-HC internal decoder or ffdshow liba52. I'm using ffdshow r3122 icl11 x86. However things are the same with some previous revisions.

Works well w/ 3114 generic. Maybe it's an ICL11-specific issue?

EDIT: my bad. AC3 decoding wasn't on libavcodec here. Same bad results. Distorted audio.

XhmikosR · 1st November 2009, 03:03

It does gives distorted output when using libavcodec for AC3. It happens with both generic and ICL11 builds.

Keiyakusha · 1st November 2009, 03:55

it looks like this is ffmpeg problem.
I can normally decode audio using ffmpeg SVN 19894, but with svn 20421 I have a bunch of errors like:
[ac3 @ 0x2268070]error decoding the audio block
[ac3 @ 0x2268070]exponent out-of-range
and audio distorted in the same way...

EDIT:
ffmpeg-r20024 -> fine
ffmpeg-r20060 -> distorted

My dual-core system is in repair for a week; I'll check it, but might not be able to until then.
