I made that post in 2006 and the part you quoted is obviously wrong. H.264 does "work" in AVI, for certain definitions of work (see deaththesheep's endless hurfing and durfing etc). It's a slightly bigger hack than XviD with b-frames in AVI is, but not very much. I wouldn't bother trying to support it though; I'm pretty sure lavf just breaks on it anyway.

Anyway, AVI is a shitty container, don't use it. I don't really see the point of including support for it in lavfsplitter either because most of the "interesting" files you will encounter in the wild rely on quirks in Microsoft's splitter anyway.

Sensation, great you did it, VC1 in .MKV plus CyberLink Video Decoder (PDVD10) go with DXVA in PotPlayer on VMR9renderless. Thanks.

Thanks for taking the time to correct yourself.

That's a good point, I have to say.

- Added support for distinguishing hearing impaired subtitles in mpeg-ts streams
- Added BluRay LPCM support
- MP1/MP2 audio media type fixes
- Honor the original FourCC of the file in media type generation
- Added support for using the Cyberlink VC-1 decoder
- Fixed an issue with some H264/AVC1 files that caused video to not play at all
- Fixed unicode in chapter names
- Fixed getting the current chapter

Download: 32-bit & 64-bit

Like you can see, this is mostly a media type and bugfix release. I hope to finally tackle some of the features on my list for 0.10.
I also finally updated my copy of ffmpeg to sync against the main ffmpeg repository, so i can keep it updated more easily.

Please report any regressions, some of the media type changes might cause breakage with some formats and decoders, but hopefully not too many. =)

Btw, the Cyberlink VC-1 decoder works like a charm, i don't even have the async issue i have with the MS decoder.

Great works like usual i go to test this build today or this evening

And thanks for Underground78 for the patch of impaired subtitles
Again Great works Nevcairiel

Doing some reading it appears that the forked version of libmpeg2 in mplayer seems to work better than the original version, might be worth looking into.

BUG: very fast playback -> http://www.mediafire.com/?yw56r54w0m9c6fw
QuickTime (AVC+AAC)

very strange. now displays correctly.

[nevcairiel]

Please always state the container format and the codecs used when reporting broken media, makes it easier to keep track of things, thanks!

LAVFSplitter better than the built-in MPC-HC for the old mov-files. But it not connect to these files.

Is there any chance of adding Media Foundation support in addition to DirectShow? It'd be nice to get support for stuff like MKV on extenders without needing to install the Divx software (plus supporting way more formats than just MKV).

[tetsuo55]

Mediafoundation is on the to-do list

[HeadlessCow]

Awesome. I knew it was on the to-do list for ffdshow, but starting on something relatively simpler (there's not 5 years of dshow hacks in the code already) like this gets a lot of the way there since a large portion of time the audio/video codecs are supported by extenders, just not the container format

[nevcairiel]

Yes, i plan to do Media Foundation.

nevcairiel,
I've sent you a PM with couple of samples that don't work with your splitter.
sample_A.mkv brings an error "Cannot load specified file" when I try to add lavfsplitter in GraphStudio. The "special" thing about this file is that it has huge amount of embedded subtitles ... 40 if I remember correctly. Haali splitter doesn't work on it too but MPC's MatroskaSplitter.ax works just fine.
sample_G.mkv crashesh GraphStudio without even given an error. The "special" thing about it is that it has two "versions" of the movie in it - both Theatrical and Extended. Haali works fine with it and gives the option to switch the streams while MPC's splitter doesn't show the two streams.
I really hope that your splitter will be "the one to rule them all".

0.9 can't be installed on a standard W7 x64 system.

Dependency Walker says MSCVP100.DLL, MSVCR100.DLL, GPSCV.DLL and IESHIMS.DLL are missing dependencies.

Log:

Error: At least one required implicit or forwarded dependency was not found.
Warning: At least one delay-load dependency module was not found.
Warning: At least one module has an unresolved import due to a missing export function in a delay-load dependent module.

EDIT:

Nevermind, just saw the message about the runtime. Perhaps this could be placed a bit more prominently in the first post (bold, bigger font, ...)

Interesting, will check it out.

I can probably fix the crash, however the mkv "editions" and ordered chapters are not supported by libavformat at this time, so i cannot easily fix this. There are plans to get this working in the future.

Greetings nevcairiel. This is excellent.

You can use TMT3 ver 175 video decoder for VC1 testing without a loader. Later versions seem to have problem with handling interlaced contents using DXVA.

By the way, any plans to support evo, like in Potplayer?

Many thanks and best eragrds.

Is not TMT VC-1 decoder 30days trail only?
Cyberlink doesnot have any limitation.

[nevcairiel]

I do own a retail copy of TMT3, so i could probably test that somehow.
I, however, have 185 installed.

You may need this. Courtesy of _shard.

[nevcairiel]

I'm currently working on defining the logic for smart stream selection, and here is what i have so far.
This is mostly based on the flag description in the mkv spec

- Filter Streams by user preferred languages
- If Streams matching language found, check if one is marked "Forced" and use that one
- If no Streams matching language found, check if one is marked "Default"
- If there is either no stream found by now, or more then one matches the criteria above, match by Quality (Codec and Resolution or number of channels, for video/audio respectively, and bitrate if available)

I want to add one option to the whole thing, that is for subtitles. You could select "Never use subs" (always select "no subtitles"), "Forced Subs" (only shows forced subs), "Always use subs" (always selects a subs stream matching your preferred language, possibly even one not set as forced to have full subs?)

Anyhow, suggestions on the whole concept are welcome!
