hoborg:
when trying to play back H.264 on a machine that does not support DXVA (and both decoders are enabled for H.264),
ffdshow DXVA Video Decoder will reject connection and ffdshow Video Decoder is used instead.

Not sure if this is the case all ready, but the VC1 decoder (and probably all ffmpeg based windows media decoders) have to reject interlaced content, because ffmpeg cannot decode that.

I also have 2 feature requests, im not sure how feasable these are

1. Import the foobar2000 noise sharpener. (http://foosion.foobar2000.org/compon...&version=1.0.0)
2. Include support for (realtime) replaygain

They mean "VMR7 / VMR9", there's no such thing as "WMR" unless it's something specific to MPC-HC.

this comes up every now and then, the problem is that ffdshow only receive the audio stream, even if replaygain data is embedded in the header of the mkv / mp3, it's not included in the audio stream, and there is no efficient method for ffdshow to get it.

If i understand correctly:
The splitter has to parse and pass on the replaygain information to the decoder, that way ffdshow and any other decoder can implement replaygain adjustment.

I'm really confused about some thing regarding FFDshow. So i got this from wiky:

Quote:

The first versions of ffdshow were published in April 2002, as an alternative to the DivX ;-) 3.11 and DivX 5.02 (which came bundled with Gator[1]) decoders of the time, and as a way to combine the speed and quality of MPlayer with popular Windows video players. It continues to support more formats, new and old, as FFmpeg developers add support for them.

The main developer was Milan Cutka. When he stopped updating the project in 2006, new maintainers opened the ffdshow-tryouts as a fork, where bugfixes, stability fixes, new features, and codec updates continue.

. So it seems DS-tryouts project stooped in late 2008, yet DS MPEG-4 is still updating...

So as mentioned above, FFDshow project was stoped in 2006 and continued by FFDshow-Tryouts since the... But when I tried to download the last version from http://ffdshow-tryout.sourceforge.net/download.php this is what I found: 2008-12-21 Beta 6 has been released! yet FFDShow MPEG-4 Video Decoder seems newer: 2010-01-09

any news about subtitles in dxva mode?
and how to change contrast and brightenss when I play my movies with ffdshow in dxva mode?

hoborg · 11th January 2010, 18:39

Hi.
I cannot test this by myself, but friend of mine told me he have this passthrough problem in rev. 3195:

AC3 and DTS passthrough is enabled
AC3 (s/PDIF encode mode) + Encode 5.1ch streams are enabled.

When he play DTS, FFDShow say DTS bitstream, but his reciever tell him it is DD, if he disable AC3 encode, reciever tells DTS.
Looks like FFDshow reencode DTS in to AC3 instead of passthrough it.

Beta6 is the latest official stable release. But development still continues and builds are available here:
http://sourceforge.net/projects/ffdshow-tryout/

her34 · 11th January 2010, 19:30

is a new beta going to be released soon since it's been over a year from last beta?

This is a bug I am working on to.

Actually this is more like an audio driver bug raised by an improvement of FFDShow audio filter.

Hmm, how can Beta 6 be a so called stable release, since even the others are beta? And in others, the "tryouts" title extansion is removed, as it was the old FFDshow continued.

clsid · 11th January 2010, 21:02

"as in others"? There are no others. All variations of ffdshow that you see from the past years are actually all the same. We all also call it just "ffdshow". The tryouts part is just for the project name on SourceForge, because "ffdshow" was obviously already in use.

Alante · 11th January 2010, 21:54

Ok.

AVC-playback isn't working for me with 3189/90 and ffmpeg-mt, libavcodec works. I had to downgrade back to 3154 to have a working ffmpeg-mt.

svc 3195 works fine for me.

tal.aloni · 11th January 2010, 22:48

I have enabled DXVA for VC-1 in rev. 3198,
however, there is still an issue with VC-1 playback.

albain · 11th January 2010, 22:48

@people having problems with AC3/DTS with AC3 encode checked

@people having problems to get AC3 passthrough/decoding on TrueHD streams and DTS passthrough/decoding on DTS-HD streams

This is fixed (I think) in revision 3197

Tal is also in good shape with DXVA, so recent added features are getting more stable

!

There is still this problem with some TrueHD tracks, the parser needs to be improved

About DXVA, please forget revisions below 3195 (and now 3198 with last fixes, this is going tooo fast)
