ffdshow tryouts project: Discussion & Development

[VipZ]

Currently there are no good batch files to build ffshow and created one due to this. The main difference for this one is that is doesn't create an installer, but creates a rar file (I make my own custom installers)

buildall_2010.bat,
@ECHO OFF

call "%VS100COMNTOOLS%vsvars32.bat"

cd bin
rm *.exe *.dll *.ilk *.ax *.vdf *.acm
cd ..\
devenv ffdshow_2010.sln /Rebuild "Release|Win32"
rd /S /Q obj\MinGW32
FOR %%A IN (ffmpeg ffmpeg-mt
) DO (
PUSHD "src\%%A"
make clean
make -j4
POPD
)

cd bin
"%programfiles%\WinRAR\rar.exe" a ffdshow_x86.rar *.exe *.dll *.ilk *.ax *.vdf *.acm
cd ..\

cd bin
rm *.exe *.dll *.ilk *.ax *.vdf *.acm
cd ..\
devenv ffdshow_2010.sln /Rebuild "Release|x64"
rd /S /Q obj\MinGW64
FOR %%A IN (ffmpeg ffmpeg-mt
) DO (
PUSHD "src\%%A"
make 64BIT=yes
make -j4
POPD
)

cd bin
"%programfiles%\WinRAR\rar.exe" a ffdshow_x64.rar *.exe *.dll *.ilk *.ax *.vdf *.acm
cd ..\

cd bin
rm *.exe *.dll *.ilk *.ax *.vdf *.acm
cd ..\

Would it be asking to much for this to be added to the svn? And modified if required.

It is only me? I got graphstudio freezes -black screen (audio still play) if i try to play h.264 using FFDshow DXVA decoder.
Using x86 2010 build 3844

I tryed older build 3775 and there is no such issue.
I will try track down revision where the problem is introduced later.

OK, 3842 is working, 3844 - 3847 = black screen.

No one have this issue?

[clsid]

Yes, it gets stuck on the first frame. I will try to fix it later today.

[TheRyuu]

What's the status on fixing 10bit h264?

I think currently ffdshow requests YV12 8bit no matter what the input is.

I think currently ffdshow requests YV12 8bit no matter what the input is.

I'm totally confused about 10bit encoding/decoding. A few posts above XhmikosR posted this supposedly 10bit sample (http://www.mediafire.com/file/4x636dmmrrfgv56/CrowdRun_720p50.x264.CRF23.10bit.mkv) and it decodes just fine using ffdshow 3850, but when I encode something using x264-10bit it's totally garbled. :confused:

9bit/10bit H.264 is not yet supported.

I have no seeking problems here with DXVA. Please upload a sample file.

[CiNcH]

Hey guys, I don't like installers too much. So I always register ffdshow manually and import my settings into the registry. ffdshow DXVA is not working this way however. The app simply crashes when using the DXVA decoder for H.264. Which file do I have to copy where to get it working?

[EDIT]
OK, I think it's latest builds that break DXVA for me, somewhere between 3814 and 3851.

I may be wrong, but all you need to do is make sure HKEY_LOCAL_MACHINE\SOFTWARE\GNU\ffdshow\noDxvaDecoder is set to 0 in your reg file and import this before you register the ax.

[CiNcH]

I used the installer by clsid now. With Rev. 3814, DXVA works, with Rev. 3851, it doesn't.

Ah sh**. Sorry guys :( . I just read the revision history within SVN and there was no mention about that...

Thanks!

Could somebody take a look @ this and maybe try to reproduce ? http://forum.doom9.org/showpost.php?p=1501021&postcount=559

Hi.
Can be FFDShow dxva decoder updated to latest MPC-HC source (including fix in 3090)?

Can you please integrate this fix? Just tryed 3853 and it is still crashing :/

Maybe it is a good time to start a new ffdshow tread, this one is really big 679 pages. Just ffdshow ( ffdshow - tryout ) something like this. I would like to hear your opinion.

[cyberbeing]

If a new thread is started, there should be some sort of landmark dividing the two. Revision ranges? New beta released? Significant new features landing? Splitting for length alone isn't a great reason, unless the forum software on Doom9 has issues with massive threads.

If you want an excuse to start a new thread, wait for all the FFDshow-specific coding to complete (hopefully very soon if not already) which will bring full-support of High10 H264 decoding to FFDshow. There appears to be an push by Dark Shikari and others for people to code what is necessary for FFDshow ASAP. That would be as good a landmark as any to start a new thread.

MPC-HC decoder working fine.
Only difference is, that it will now popup some kind of VC++ error message.

[TheRyuu]

So about that libmpeg2 gcc fix (http://forum.doom9.org/showthread.php?p=1500198#post1500198)...

[Mr VacBob]

I made a commit to ffmpeg-mt which should fix the problem with 'Avatar-Bluray-ffmpeg-mt-corruption.m2ts'. However, since the problem doesn't reproduce with ffplay, I haven't actually tested this. Also, I suspect it's made the decoder noticeably slower per thread :/

10-bit is also merged in, but one of the tests fails with threading on, and I haven't spotted the problem yet.

[CruNcher]

recent tests i did showed the libavcodec mpeg-2 part is much faster in a multithreaded framework then the libmpeg2 decoder in the current ffdshow (4 cores), ffdshow_rev3853_20110512_xhmikosr_icl12.exe <- tested, does this include the newest ffmpeg-mt ?
Dscaler IVTC mod was surprisingly being such old the fastest (+ 3 fps) :), though Dscaler differs output wise from libavcodec/libmpeg2 in ffdshow on interlaced material with it's field selection it seems (it's not identical to ffdshow)

[clsid]

@hoborg
Wasn't that a broken file? Can you upload it for me? Then I can try to fix the crash.

@TheRyuu
I will have a look at it this weekend.

@Mr VacBob
Great! I will update asap.

@CruNcher
The libavcodec mpeg2 decoder uses slice based threading. It has done that for ages already. It doesn't use frame based threading like ffmpeg-mt does.

Ahh sorry i see ffmpeg-mt for mpeg-2 is not in ffdshow yet, but seeing that dscaler does better then libavcodec in ffdshow (performance) still surprises me wasn't it based on libmpeg2 ?

MPEG2 uses slice threading in ffmpeg-mt. All MPEG2 files have lots of slices, so I think this is faster.

I have a specific issue in PowerPoint 2010 which seems to be caused by ffdshow. Starting with builds > 3763 PowerPoint freezes when trying to play dv files (at least dvsd) in the 2010 native mode (the mode in which the PowerPoint displays a timeline for the videos).

I tried several other decoders (Medialooks, Microsoft - among others) and they do not exhibit this behaviour. Also, I tried it on different computers with Win7 64 bits (e. g. Intel H55 - Intel Graphics, Intel P35 - AMD ATI Graphics, etc.).

Maybe someone here using PowerPoint 2010 (or the free player) can help me with this. I already posted this issue in the bug tracking system and I would be very grateful for a solution.

The following 2 files demonstrate the problem:

http://www.mediafire.com/?3q2wxwne4bxnxb5 (DVSD_Example.avi)
http://www.mediafire.com/?gcarlp7h4k66vbh (DVSD_Example.pptx with linked video)

Beside the PowerPoint 2010 issue, I came across the following two files which could not be decoded at all by ffdShow (using LAVSplitter):

http://www.mediafire.com/?8fwcaxepy3xca4v (Apple_DVCP_small.mov)
http://www.mediafire.com/?ch5rgnqbam6gi1v (WMV3_WMV9.wmv)

Could this just be a matter of a missing media type or are these formats simply not implemented? If they are not available at all, does someone know which ds decoders support these? (while not being dmo decoders/source filters/splitters at the same time as I would very much prefer to keep using LAVSplitter as my default splitter for wmv/mov files)

I noticed this error popup with a lot of *.TS HD/FullHD recordings too, even if i disable FFDShow DXVA decoder and use FFMPEG-MT.

The powerpoint issue is probably related to some colorspace changes that were made some time ago. Please play a bit with the settings on the Output page in an older version of ffdshow to see if you can reproduce the problem of the newer versions. For example disable RGB24.

[Sven75]

This is what I was assuming too when I read the changelogs after version 3763.

I already tried enabling and disabling all output colorspaces and related options. In every version (I tried) after 3763 and up to 3853 PowerPoint always freezes in the same way when starting the video (not displaying a single frame of the clip).

In version 3611 I cannot make PowerPoint freeze - no matter which colorspace setting I use. Also, as soon as I deactivate all YUV colorspaces and 32 bit RGB (leaving enabled only 24 bit RGB in the settings) PowerPoint will no longer use ffdshow at all but fallback to AVI Compressor (resulting in a terrible image quality, but not freezing).

[clsid]

I will try to reproduce once I have all the parts of my new dev PC.

[Sven75]

Ok, great - thank you!

I found a problem with ffdshow video decoder. It detects my x264-encoded video's framerate as 25 fps, which is incorrect (23.976 is the correct framerate), this causes the video and audio to be unsynced. The problem occurs only when I set x264's input directly to the mkv, not AviSynth script. I tried CoreAVC and MPC-HC internal decoder, they are fine. I'm using ffdshow tryouts r3800 (MSVC 2008, x86, unicode).
Here is the sample: http://www.mediafire.com/?fxp9699r9ius6gh

Strangely, when I remuxed your sample with mkvmerge v4.5.0, that problem was solved.

I cannot judge the cause is either ffdshow or mkvmerge :confused:

[BloodySword]

Hi everybody. I have a small problem with mpeg2 decoding with ffdshow tryouts.

System details:
Windows 7 Professional x64
ffdshow tryouts rev3851 May 12 2011 03:05:21 (ICL 10, x86, unicode, r)

When I use libavcodec to decode mpeg2 I have massive A/V synch problems when using Yadif or Kernel bob deinterlacing while playing vob files.
When I use libavcodec to decode DVB-T (Hauppauge WinTV 7) everything's fine, deblocking and deringing works
But I can not play vob files well :(

When I use libmpeg2 instead it works find for both vob and DVB-T. But: Deblocking and deringing does not work.
It seems like the quantizer reported from libmpeg2 is so high (1 or 0) that deblocking does simply nothing,
regardless if I set strenghth to 200% or not. I use mplayer deblocking with all filters active: Deblock, Dering, H V Luma and Chroma.

How can I force libmpeg2 to deblock and dering? :(

Edit: The newest version of ffdhow (above) crashes at the end of a VOB file (looks like while retrieving last frame).

Thank you in advance.

[cyberbeing]

@Spynask & Chikuzen

No 'Default Duration' (default frame duration aka frame-rate) is specified in Spynask's MKV container, but since that element is non-mandatory, the MKV is still following spec and should be able to be handled correctly. A bug in FFDshow must causing it to default to 25fps when the splitter doesn't report a 'Default Duration', rather than determining the frame-rate from the video stream. Chikuzen, your file does specify a 'Default Duration', so you must have specified a frame-rate when re-muxing with mkvmerge.

[VipZ]

Hi,

I have found that with this sample, ffdshow doesn't honour the AR flag's, MPC displays at the correct AR.

http://www.mediafire.com/?t1i1fqcj6qhwb4s

Thanks

[clsid]

AR is correct when using Haali splitter. But that replaces some data in the video stream with AR info from the container.

You might be able to 'fix' the problem by remuxing the file.

[VipZ]

I was using LAV Splitter for this, which does pass the AR to MPC decoders. When creating the sample I verified the AR was set correctly when remuxing (mkvmerge 4.7.0)

[hoborg]

Strange, it still crashing for me :/
MPC-HC decoder working fine.
Only difference is, that it will now popup some kind of VC++ error message.

Here is a .ts sample. (https://rapidshare.com/files/1479703935/crash.zip)

FFDShow DXVA = crash
FFDShow ffmpeg-mt = crash
FFDShow libavcodec = working fine

[clsid]

H.264 crash is fixed.

[alexins]

clsid, in ffdshow r.3857 not fully work decoding of video files using the libavcodec and ffmpeg-mt. Via DXVA decoding works well.

[clsid]

Please be more specific about what is wrong. I don't notice any problems.

Also test 3855.

[hoborg]

H.264 crash is fixed.

I just tested 3855 and both samples (MKV + TS) still crashing with FDshow DXVA decoder.
ffmpeg-mt working now.

[clsid]

DXVA crash fixed in 3858.
Powerpoint freeze fixed in 3859.

[Sven75]

Any specific reason why it only froze with dvsd and PowerPoint? From what I can deduce from the code changes it does not have anything to do with colorspaces but rather with setting ar info for the video renderer, does it?

Anyway, I will try 3859 asap. Thanks a lot - really!

[clsid]

I don't know. I have just replicated the behavior of a setting present in older versions of ffdshow that worked.
