ffdshow tryouts project: Discussion & Development

[Reino]

Just two, I think easy to fix, old bug-reports:
- Volume levels animation glitch on WavPack audio
- Vorbis audio input bitrate incorrectly being reported

I would very much appreciate it if anyone could have a look at it.

[edit]
- Feature Request: Dedicated DTS-in-WAV-decoder
Playing DTS in WAV without the need to set the Uncompressed format to "All supported" (or "16-bit integer").

Can I get a bulid 4429 installer?

everyone:
Anyone knows why 'xvidvideo.ru' stopped generating the latest builds automatically?

[LigH]

Because it is not done automatically, but a human has to launch the compiler. And he might be on vacation.

@ Blight:

Xhmikosr has built it already,

[EDIT]

xvidvideo.ru has been updated,

Thanks I've got the file. I'll take a look when I have time.

There are some problems with ffdshow DXVA. external .srt subtitles wont show with VC-1 (DXVA), file mkv/vc-1/dts. It works on ffdshow_rev4224_20120105_xvidvideo-ru_x64-MSVC2010 but is broken on all builds after 4307, there weren't builds between those in xvidvideo.ru so don't know exactly when it broke. I'm using LAV splitter, ffdshow x64 DXVA and Radeon 7750.

There was also problem that I've had couple of months on latest builds. With Haali media splitter and ffdshow DXVA + subtitles I get error on player when trying to play the file (mkv/vc1/dts). With LAV splitter and ffdshow DXVA + srt subtitles all is fine. I don't know when this broke since I've moved to LAV splitter but might be related to the first bug.

These both are only with mkv files containing VC-1 video, player I used is WMP12 and Media Center.

Midzuki, LigH:
Thanks

I've noticed that the XvidVideo.ru site is building ffmpeg with a pre-release version of GCC (according to their web site). This is usually not a good idea...

They've always been doing that. Who knows why.
Just get builds here:
http://xhmikosr.1f0.de/ffdshow/

Build with latest stable GCC (4.7.0)

FYI, this site is fire walled by Intel's IT.

To clarify, VC-1 on WMP12 refused to play and on Media Center I got "Microsoft Visual C++ Runtime Library, Runtime Error!" when started playback. If I swap to LAV splitter then these errors disappear and everything is fine except no DXVA subs on VC-1. 4229 ffdshow_rev4224_20120105_xvidvideo-ru_x64-MSVC2010 is the last working build.

You should try r4431 and post a sample file if it doesn't work.

Same with r4431. This is weird as I would think others would have had the same problems too, I've had these problems for months. I thought it was something at my end and was lazy to format, then I build a new computer and still having the same problems so i'm fairly certain it's a bug. Clean W7 SP1 64-bit install, installed all updates, Catalyst 12.3, haali media splitter, ffdshow x64 and set up subtitles and DXVA for VC-1 and H.264. Used the Win7DSFilterTweaker_5_2 to disable media foundation and changed the preferred decoders to ffdshow DXVA. For playback I used 64-bit WMP12 or WMC.

Problems:
Haali splitter + ffdshow DXVA > r4224, error playing VC-1 mkv or m2ts. (WMP12 doesn't play the file, WMC gives some C++ error)
LAV splitter + ffdshow DXVA > r4224, files play fine but no subtitles on files containing VC-1.

Sample

[nevcairiel]

DXVA subtitles in ffdshow are a ugly hack anyway, i'm actually surprised it worked as good as it does without causing massive corruptions. You cannot paint subtitles onto a frame which is still used as a reference frame in the decoder.

r4257 is working, r4291 is not
I get no crash or errors at all with my own builds, so try the builds from sf.net.
The splitter also shouldn't matter since you are using an external subtitle file.

@Haruhiko
Could the subtitle issue perhaps be related to r4263/4268?

I'll take a look when I have time.

I'm getting user-reports that clsid's build 4431 breaks 10bit decoding.
Can anyone confirm?

It should not only break, but crash.
The issue was fixed in 4432, it was a problem from libav, which was fixed there.

[Blight]

Thanks for the info nev!

clsid:
Any chance you can create a 4432+ build?
I noticed you mentioned other (xvidvideo.ru?) build suffer from some issues.
