ffdshow incorporates a MSVC-buildable version of libavcodec. Very helpful for debugging, but I know a couple of months ago it wasn't quite buildable anymore. I've seen a few MSVC compatibility messages go through svn since then, not sure of the exact status now, I'll test when I get home. That might be simpler to use than the raw ffmpeg version. (MSVC can't do any of the inline asm, though.)

I think libavcodec was recently made MSVC buildable according to the SVN changelog...

just a small bug report:
- if the disk is full, dgavcindex continues, without an error, but the file is incomplete, because the disk is full

Okay, it builds fine in VC 2005. Can't test whether the VC 2003 project is up to date. If you want to check it out, it's under sourceforge project ffdshow-tryout, path /trunk/src/ffmpeg, and it will build the dll by default in /trunk/bin. Of course, you can strip out all the extraneous codecs.

It has some dependencies on ffdshow, mainly replacing its codec naming/ordering etc with ffdshow's, and some ffdshow-specific hooks, so it's worth checking the whole project out, or at least the trunk branch. Any patch you make against it should be applyable back onto the svn ffmpeg code.

Is there a free version of VC 2005 that will build it? I still use VC 6.0

Does it also build the libs needed to dynamically link the DLLs?

@neuron2: VC2005 Express edition is free.

I would appreciate a version based on the reference implentation by JM , because of the PAFF-Support and the Accurancy.

VC Express is indeed the way to go for a free kit. I think they were doing the VC2003 binaries a while ago too, not sure if they're still kicking around MSDN somewhere.

it would be nice. but that will take a lot of time to optimize. i don't want to even imagine how fast it will run on my A64 3000+@2,34GHz

Well yes, but so was the reference MPEG2 decoder that developed into the heart of DVD2AVI, DGMPGDec, etc. I'm still mulling it over.

Yeah, the libs will show up in ./Release (Debug, whatever), and not the bin folder, though.

OK, thank you. I have managed to build it using VC 2005. Now it seems sensible to just make DGAVCIndex buildable under VC 2005 and then incorporate the AVC decoder code directly, so that no external DLL is necessary.

Then add PAFF.

BTW, active SPS/PPS management is something of a nightmare for random access.

@neuron2

Only if you care:
Video: MPEG4 Video (H264) 960x1088 [Video] <-- AR 16:9
(from canal ad on hispasat 30 west)
(maybe bond is interested too, how crappy it looks)

But for DGAVCDEC testing purposes:
Canal.AD.ts 23mb

(playback: mpc internal .ts splitter works, haali splitter says: Unspecified error, reported to Haali)

Jeez....

That sample contains six different "Program" sectors. Only the last one (Program 900) contains the video and audio stream.

I want to make this post just to thank you, and compliment you on your excellent work.

I've just used DGAVCIndex to succesfully replace the video on my DVD with a, resized but very much improved, AVC-720p version My DVD went from OK to sublime after the replacing (50i PAL to PAL anamorphic 25 fps progressive). So for me the tool works like a charm.

Now only VC-1 is left to do, as far as i can read around here, and all HD-possible formats can be input in AviSynth succesfully (i.e. without using DSS() ).

So

Glad to hear it. But there's still a lot of work to do. Right now I am in the midst of upgrading to VC++ 2005 and pulling in libavcodec code so that I will be able to develop and debug transparently, without the hassle of DLLs built in a different environment, etc.

Just a little progress update in case you're wondering what is going on.

Recall that I am in the process of moving to the ffdshow-tryouts based code that will allow me to build the DLLs using Visual Studio and later integrate the code directly, eliminating the DLLs. That will greatly simplify further development and debugging, especially adding PAFF support.

Converting DGAVCIndex and DGAVCDecode for building under Visual Studio 2005 Express was straightforward. (I also did it for DGMPGDec.)

The first problem I ran into was that the ffdshow-tryouts build of ffmpeg's DLLs includes only a stub for libavformat, whereas I was heavily relying on it. So I had to find a way to use libavcodec for H264 decoding without libavformat. I have now accomplished that successfully.

The next step is to convert from the DLLs built in the pseudo-linux (MSYS) environment to the DLLs built in the ffdshow-tryouts environment. At that point everything will be buildable and debuggable using Visual Studio. After that I will integrate the decoder directly and eliminate the DLLS. Then proper development of needed functionality will resume.
