2. Where can I find a "donate"-button for this project?

I already posted this crash here. Happens for me for every h.264 file. Albein said he's going to fix it, but it seems he didn't have enough time.

Hm, looks like there's a separate function for deblocking h.264? Normally I'm using SPP for DIVX/MPEG2 with different strenghts. But on a h.264 video even weak deblocking is blurrying the whole thing.

[Astrophizz]

H.264 has its own in-loop deblocking. Any further deblocking would blur the image as you have seen.

[Mr VacBob]

There is no reason to use spp or pp as a postprocessor for FF_QSCALE_TYPE_H264. Something like gradfun is more appropriate.

I know. I'm only wondering, why the builtin post processing do so much blur on h-264 videos. On good videos I cannot see an effect of applying SPP deblocking to MPEG2 or MPEG4-ASP videos, no blurrying. I'd expect this behaviour for h.264, too.

[Mr VacBob]

H.264 has more than 10x larger qp values, and it's ignoring that the values mean something different for it, so it applies more than 10x too much postprocessing.

Sounds like a reasonable explaination why. Thanks!

Hi.

I just tested ffdshow_rev3345_20100402.exe build, CTRL+ALT+F4 or CTRL+ALT+numpad1 still doesnot working for me.
Only me ?

Sorry for the late reply ...


I do not see this issue with the following builds:

- ffdshow_rev3304_20100304_sse_icl11 (ICL11, x86; xvidvideo.ru)

- ffdshow_rev3305_20100304_clsid_icl10 (ICL10, x86; SourceForge)

I see this issue with the following builds:

Probably related to rev. 3335: "added H264 format to postprocessing filter" -- maybe I should have changed some option there?

[clsid]

I tested with PP disabled, so that would likely be the cause.
That change has been reverted in 3347, so your problem is probably fixed now.

I have a DTS passthrough issue with ffdshow. I'm currently using ffdshow_rev3342_20100331_clsid and a Radeon HD4xxx's HDMI output (supports SPDIF, but no 7.1/HD-audio).

I previously used the ffdshow version of the CCCP which is totally outdated but there I had no problems. For the ffdshow settings see the attached screenshot.

File 1:

ID                               : 2
Format                           : DTS
Format/Info                      : Digital Theater Systems
Format-Profil                    : ES
Codec-ID                         : A_DTS
Dauer                            : 1h 40min
Bitraten-Modus                   : konstant
Bitrate                          : 755 Kbps
Kanäle                           : 6 Kanäle
Kanal-Positionen                 : Front: L C R, Surround: L R, LFE
Samplingrate                     : 48,0 KHz
Auflösung                        : 24 bits
Stream-Größe                     : 544 MiB (27%)
Titel                            : 5.1 DTS

This file works fine with the old and the most recent ffdshow.

Audio
ID                               : 3
Format                           : DTS
Format/Info                      : Digital Theater Systems
Format-Profil                    : MA
Codec-ID                         : A_DTS
Dauer                            : 45min
Bitraten-Modus                   : variabel
Kanäle                           : 6 Kanäle
Kanal-Positionen                 : Front: L C R, Surround: L R, LFE
Samplingrate                     : 48,0 KHz
Auflösung                        : 16 bits

This file only works with the old ffdshow version or when I use MPC-HC internal DTS decoder for SPDIF passthrough.
I know it's DTS-MA but the core should still be a DTS bitstream right?
PS: Enabling DTS HD bitstream doesn't make any difference. My AV Receiver is Onkyo TX-SR607.

Hi,

about bluray subtitles and subtitles in general, I am still working on it.

Pel (supread creator) and I are working on making a better PGS format support

The current implementation is not correct but I think I am close to the solution

There is also the new ffmpeg libs on their way, the last issues to fix

Hi albain, does your work include work on the dvd format vobsub subs aswell?

I am mainly thinking of this bug stated on the front page:

2. In some cases VobSub subtitle files (.idx/.sub) are loaded, but no subs are displayed. VobSub support is still incomplete.

As it is now, some movies will start with subtitles working fine, but after a while they disappear.

If it helps, vsfilter does not have this issue.

Albain, did you finally disable jitter correction for THD? With the lastest revisions I get huge jitter (30 segs or more) that is causing crashes, silence and audio desync with m2ts files here. No issues with matroska though, jitter is always at ~0. Can anybody confirm?

Confirmed.

Hi, I use ffdshow in delphi app, and every time you guys
change iffdecoder I had to update my prog.
But you didn't update iffdecoder.h (nor delphi interface) in time.
Please update interface units.
Thanks

About DXVA + Haali + FF/RW : I'll make some deeper tests with 720p mkv to reproduce it

The only difference with you is that I own windows 7 x64

Hi Albain,

Just wanted to give you a heads up, but I tested with the newest Haali and I still get crashing while ff/rew with any mkv while using ffdshow dxva. I know you are aware (and very busy) but I wanted to let you know. Would love this to be fixed personally, as its the only thing from preventing me from using ffdshow dxva within Windows Media Center.

Thanks

Could you explain a little more ?

@All : I have fixed the last issues on new ffmpeg libraries (nv12 black screen). Now everything is working
I'm doing some code cleanings but the modifications are ready to be committed.
