messing around with directshow filters...

[lexor]

oh man I wish players had a tab in the options where you could assign decoder for each codec type. But I guess it's too hard to do, considering all the different codecs out there.

zoomplayer had something like this I recall, using merits or something, but it never worked for me.

not quite, it would have been easy to do that if the field of codecs was stable, but we have now rapid development, only a few days ago we had no idea core team was working on their uber decoder. We test, experiment, and it would be much simpler to do that if I could just set the decoder in the player instead of wrestling with windows, installing/uninstalling/registring/unregistring.

Zoomplayer Pros Custom Filter Preferences work fine, it has a list of Codecs and Contaienrs and let's you select a specific filter, however Custom Playback is only enabled in Pro Version, nothing to do with Merits, Zoomplayer can edit DirectShow Filters Merits in the registered filter manager, but you could also do that in registry and it is provided by DShow and has nothing really to do with ZoomPlayer. In MPC you can use the Overrides Function in the Options, just block the filter and only allow the one you want to use, as each filter added has a checkbox you can easily change to something else.

Over the weekend I decided to format one of my WinXP boot partitions and carry out some "video" and "audio" filter experiments.

I've installed MediaPlayer Classic V6.4.8.7 as my primary media player (as I'm fairly used to its settings) and Windows Media Player 10 (because it's there).

So far, the only filters I've installed are CoreAVC v0.0.0.3 Alpha (2006-01-09) and XviD 1.1 final (Koepi's Build).

However, I've discovered that even when MediaPlayer Classic's "MP4" Source filter is "un-checked", MPC appears to use it and gives it a "low merit": -

http://img206.imageshack.us/img206/8340/mpccoreavc2ct.png


Now, although I can get Media Player Classic to play MPEG-4 "AVC" video within MP4 using "CoreAVCDecoder.ax" I'm unable to get Media Player Classic to play MPEG-4 "SP/ASP" video within MP4 using "XviD.ax"

Now I'm sure some of you will simply say "install Haali", but that will not explain why this happens....

That said, maybe "CoreAVCDecoder.ax" could grow to include MPEG-4 SP/ASP decoding too..... Now that would be handy ;)


Cheers

[videomixer9]

No need for that, please keep CoreAVC doing AVC ... btw. what should MPC do otherwise, throw out an error because of missing filters? I guess just using the internal one is a better solution ...

[SeeMoreDigital]

...btw. what should MPC do otherwise, throw out an error because of missing filters? I guess just using the internal one is a better solution ...Well..... if MPC is able to do this for MPEG-4 AVC in MP4... why can't it do the same with MPEG-4 SP/ASP in MP4?

You see the quandary here?

[[Toff]]

Funny you mentioned that....

Yes you have no other splitter to handle mp4, MPC will use his own internal low merit filter.

Now, although I can get Media Player Classic to play MPEG-4 "AVC" video within MP4 using "CoreAVCDecoder.ax" I'm unable to get Media Player Classic to play MPEG-4 "SP/ASP" video within MP4 using "XviD.ax"
This has nothing to do with CoreAVC which only handle file with AVC1, H264 or X264 fourccs.

That said, maybe "CoreAVCDecoder.ax" could grow to include MPEG-4 SP/ASP decoding too..... Now that would be handy ;)
That would not be so great, the concept of DirectShow is to separate task as much as possible and let each filter do his job. It's with this kind of macro-filters (e.g. ffdshow) that it get difficult to select which codec you want to use in your player.

@SeeMoreDigital: This is the CoreAVC. You may ask for a CoreASP but not to include that in CoreAVC.

[[Toff]]

Even if it's in .MP4 there must be a mapping in DirectShow to tell what decoder to use, it's the role of the "mediatype" which contain some identifier, most mediatype still use a FOURCC like mapping.
For example the FOURCC "MP4V" is used here to play this sample http://trailers.nerodigital.com/Sony/Underworld_stan.mp4 in combination with Haali's splitter.

I've just looked at the mediatype used in graphedit for the connection.

The end of the file thing should work with any mp4 ... sometimes you find some type thing at the begin but that's nothing to do with mp4 but whatever the video was before muxing someone told me ... I just feel so leet doing it that way :)

I just feel so leet doing it that way :)Like I say.... what you understand as being 4CC codes, such as "AVC1, H264 or X264" don't exist for MP4 files.

When MPEG-4 AVC video is placed within MP4, it adopts (what MP4Box calls) a "Sub Type" code, which is "AVC1": -

sorry, I'm unable to do overlay screen captures (HyperSnap-DX just captures the overlay frame but not the whole screen with an moving overlay-video in the back, or I'm just to stupid)

my findings so far...

AR signaling doesn't work with your clip as already mentioned - I'm using VMR7 (windowed) = standard renderer

besides I'm so happy with CoreAVC. Your DSFilter just rocks!!

Strange! I blocked all other mp4 parsers/splitters in MPC and tried 6.4.8.7 with Koepi's XviD 1.2.-127 standalone build (Jan 08-06) and it worked. However, if I uncheck the MPC mp4 source filter box, I get an error, rather than the low merit result that you described.

It's probably just as easy to put a copy of regdrop.exe on your desktop. Then put all your DSFs in one folder with a link on the desktop. To enable/disable DSFs, simple drag and drop the files to regdrop (drop with the shift key depressed to unregsiter).
']KIt's with this kind of macro-filters (e.g. ffdshow) that it get difficult to select which codec you want to use in your player.
Actually, this is quite easy in ffdshow, given the thougtful, codecs page. Bloatware is another issue! ;)

It maybe easy for the user, but it make it hard to integrate in an application, It need special handling from the player side. And even for users it's sometime messy because they just install it and don't know how to configure it.

[videomixer9]

You must be pretty much of an idiot if you cannot figure out ffdshow. I think anything else but this is an arguments contra ffdshow, one major bad thing about ffdshow is that it doesn't keep up with the underlying codecs and loses optimizations, e.g. in VLC libav is used multithreaded while it isn't in ffdshow. Generally ffdshows problem is that the author has to keep up with many underlying libraries being worked on getting more and more optimized for special things and sometimes stays behind developments for some time, which is something that bugs me a long time now.

I wonder whether it's worth starting a separate thread about this specific issue....

Maybe Bond could split some of the MPEG-4 SP/ASP within MP4 parsing posts out of this thread and into a new one?

was such a statement really needed ?

[videomixer9]

was such a statement really needed ?

Why, it's a compliment for milan for packing all those features but still quite intuitive into one config page. Some ppl might be overwhelmed by the amount, but yet I never had anything against that dialog in it current form, it's nothing spectacular, but nowadays some ppl think that making dialogs look as fancy as possible and hiding options in networks of funky pages is user friendly, it's simply not, also giving the user not that much choices isn't a good way either. I'm quite upset how more and more tools give you less to configure in favor of claiming to have easy configs. And imo ppl that give up just because they see lots of things being in a dialog are idiots, as they are obviously not even willing to read or analyse what they see. I wonder how such ppl can drive cars, you have to analyse so much things and have so many switches hidden away in all kinds of methods, and imo that's good too, imagine funky flashy menus for turning on your lights or anything just be automatic, like the cars decides itself if you need lights etc. anybody would call ppl that require that idiots ...

Well as to CoreAVC I see currently not much to configure in it anyways, turning off deblocking or whatever is not needed with that fast of a decoder, but maybe there could be some controls for AR signalling like in xvid, or for selecting the fourccs the filter accepts and maybe someday if it gets more colorspace an option to select this. I doubt ppl that didn't figure out ffdshow figure out that either though. It's just software and you can try stuff out unlike with your car while driving in public ...

[dragongodz]

exactly. newbies or inexperienced people may be a little confused or whatever the first time they see it. that doesnt make them idiots. it would have simply been nicer to say something like "with a little effort ffdshows config isnt that hard to use". calling them idiots will simply discourage them from asking about anything that may confuse them.

[[)370|\|470!2]

You must be pretty much of an idiot if you cannot figure out ffdshow.

If you could call some1 an idiot for such a small reason, you'must be something even lower.


dragongodz 100% Agree

I've included some installation instructions (and "bat" files) to the latest version of CoreAVC_DSDec.zip (http://81.98.148.105/Uploaded_Files/Doom9_Forum_files/CoreAVC_DSDec.zip)

Hope that helps you out ;)


Cheers

i have register but WMP 10 will use the Nero DVD Decoder. when i unregister the Nero Decoder i can not play any mpg Videos. i have test with MPC but i can not see the CoreAVC Codec. by Filter i see only Video Renderer ?? i will use CoreAVC for *.mpg and *.ts ans all other supportet Videos.

[Scoty]

regsvr32 /s CoreAVCDecoder.ax
And you shouldn't uninstall ffdshow.
You should change decoding option in codec settings: "H.264" to "disabled" and "RAW" to "supported all".
With this, you could do color space conversion with ffdshow for CoreAVC decoded stream.

i have disabled H.264 bur the MPC will not use ffdshow. only WMP will use ffdshow but without CoreAVC. is CoreAVC only a H.264 Codec ? i have a many *.ts and mpg Videos but this use not H.264.

[sillKotscha]

is CoreAVC only a H.264 Codec ? i have a many *.ts and mpg Videos but this use not H.264.
yes it is ;)

ads I said to you...

your *.ts and mpg Videos need a mpeg2 decoder *point*

except for .ts if h.264 video is inside but than again, coreavc won't decode your stream as long as we don't have a parser for it

ok the problem is solved. the CoreAVC is not the right Codec for me. can the CoreAVC in the Future decode mpg2 or ts ? which is the best Codec for ts and mpg2 ?

[sillKotscha]

mate, CoreAVC is not a codec. It is a decoder for h.264 encoded streams. So, why should an avc_decoder decode mpeg2 video??

if you use mpc for watching video files, than you can use build_in mpeg2 decoder.

the build_in mpeg2 decoder is not good for me. the picture quality is good but not perfect.

[[)370|\|470!2]

Try ELECARD MPEG 2 Video Decoder (http://www.doom9.org/Soft21/Filters/MPGDec.zip)

[Mug Funky]

the picture quality is good but not perfect.

perhaps you should play with it's deinterlacing settings...

any spec compliant mpeg-2 decoder should deliver the same results as any other spec compliant mpeg-2 decoder. so mpc's in-built decoder should be fine so long as you've got the CPU (i'll hazard a guess that you do, as you're decoding AVC which is far more taxing).

[BetaBoy]

ok the problem is solved. the CoreAVC is not the right Codec for me. can the CoreAVC in the Future decode mpg2 or ts ? which is the best Codec for ts and mpg2 ?

MPEG-2 is coming but unlike CoreAVC will only be available internally within CoreCodec and to those third parties that license TCPMP + MPEG-2 decoding and aquired the appropriate licensing.

[Ice =A=]

Posting in some thread about an MPEG4 decoder and asking for suggestions and help about an MPEG2 codec, well... :)
Anyway, don't forget that each program with an MPEG2 implementation has to pay license fees. It would even have been illegal to offer such a program like (it is done here) for testing, I believe.
