LGPL libavcodec for DGAVCDec

[neuron2]

In an effort to get DGAVCDec back in action I have built a fully LGPL version of libavcodec. I would appreciate testing. Just replace your libavcodec.dll with the one in this ZIP file. Please advise if you run into any issues.

Note that this is the same version of the lavc code previously used, so do not expect any PAFF decoding improvements (yet).

Thanks; It says "couldn't load libavcodec.dll" when I try to start DGAVCIndex.exe

Same here:
Error: Couldn't load f:\dgavcdec\libavcodec.dll

Dependency Walker says:
Error: The Side-by-Side configuration information in "f:\dgavcdec\LIBAVCODEC.DLL" contains errors.

Weird. I'll look at it later this evening. Works fine for me. What OS are you using?

[clsid]

This means that the DLL needs the VC++ runtime. Or it does not really need it, but you forgot to disable manifest embedding in the project options.

Why not use GCC? That should give much better performance.

What OS are you using?

The PC I tested it on has XP 32-bit as the OS

[Brazil2]

Windows XP 32 bits here too with VC++ 2005 and 2008 runtimes installed.

In Dependency Walker the original DLL loads KERNEL32.DLL and MSVCRT.DLL but the new one loads KERNEL32.DLL and MSVCR80.DLL.

Windows 7 x64, no problems so far

MSVCR80.DLL is the Microsoft Visual C++ 2005 runtime library.

If the binary wasn't statically linked to the runtime, then you will need this:
http://www.microsoft.com/downloads/details.aspx?FamilyId=32BC1BEE-A3F9-4C13-9C99-220B62A191EE&displaylang=en

And if it works for you without that download, the runtime was already installed before, obviously :)
Quite possible that it ships with Window 7, but did not ship with Windows XP...

[neuron2]

OK, guys thanks. I think I'll take the advice about gcc, as it gives a 20% performance improvement as clsid alluded to.

Patience, we're coming back strong with this project.

I have an FFMPEG issue 1592 that needs resolving to absorb the latest libavcodec.

Great news! Hopefully this ends any question of license issues that have cropped up recently, and ends the unfortunate feud between two prominent board members :)

Cheers!

Is this the same sample you have issue? http://samples.mplayerhq.hu/V-codecs/h264/sony-hdr-cx6-avchd-interlaced-decoding-problem/sony-hdr-cx-6-avchd-1080i-9-seconds.mts
It has same dropped frames issue, but only if video is demuxed
If video converted without demuxing, output is good
ffmpeg -i sony-hdr-cx-6-avchd-1080i-9-seconds.mts -an -r 25 -vcodec ffvhuff sony.avi

[neuron2]

I don't know if it is the same, but it is a Sony sample.

Yes, it fails for me with the ES, which I uploaded for the FFMPEG guys.

It needs to be fixed because we need to support random access with ES.

The new version works fine for me in Windows 7 :)

[edtee]

Just to confirm... It works for me too, on Win7.

PS:Great to see you at this again. I'm not a big poster, but am a huge user/fan of your work. You rock and I've always appreciated your work.:thanks:

i am not programmer.., but i thought that you only need from ffmpeg is h264 decoder, and ffmpeg decode correctly all my videos in TS format. And all my videos in ES have dropped frames issue with ffmpeg, even video (ES) that works good in DGAVCDec 1.09, fails in ffmpeg (dropped frames issue)
sorry if i make no sense :)

Yesterday ffmpeg added H264 DXVA2 implementation (http://git.ffmpeg.org/?p=ffmpeg;a=commit;h=6e3d7762f1d54dcaa783b67e370fb77ad73c8e79), is it possible to use DXVA2 decoder for DGAVCDec?

dxva2 (bit.ly/7ScmC2)
