please help with the H.264 format!

[jogginman]

Hello

I have numerous mp4 files that I want to be able to playback on my standalone divx player but at the moment they will not play so I am looking at converting to divx/xvid which ever is easiest.

According to QT7 the file format is as follows:
MPEG-4 ODSM
MPEG-4 SDSM
H.264, 496x368, millions
AAC stereo (l, r) 24.000khz
also its using the AVC codec thingy :)

I have got River Past video cleaner and have tried converting it to an uncompressed video file and it was big 33gb or so :) i was then gonna use vdub to convert to divx5 but when i try play video back i get sound but just a complete black video nothing.

Can anyone explain what I am doing wrong and how to do this.

TIA!

:thanks:

can you play the .mp4 file in a directshow based player, like wmp10 or mpc?

if no, than install filters which make you be able to play it (as ffdshow + coreaac + haali's media splitter, or nero vision express)
after that continue reading

if yes, than use avisynth with the following line for loading the source:
directshowsource("c:\path to\your.mp4",fps=25)

than load that .avs script into virtualdub, set the video and audio encoding formats (eg divx5 or xvid and mp3) and encode to .avi as you always do


edit:
btw h.264 = avc
and from your samplerate i guess your audio stream is he-aac, which qt7 cant decode with full quality

[jogginman]

cheers for reply bond but it doesn't work :confused:

I installed the filters etc you mentioned proceeded into vdub attempted to load the avs script and got the following error:
Avisynth open failure:
Directshowsource: Could not open as video or audio

Video returned: "Directshowsource: the filter graph manager won't talk to me"

Audio returned: "Directshowsource: the filter graph manager won't talk to me"

What am I doing wrong? or is my system screwed??

:thanks:

[bond]

which filters did you install?

can you play the file in a directshow player?

[jogginman]

i installed ffdshow coreaac and haali's media splitter... and no i still get no picture when try to play in WMP10 just get audio.

[bond]

did you enable h.264 support in ffdshow?

[jogginman]

looked in ffdshow properties and H.264 format was disabled so I set this to "libavcodec" only value there and oked this loaded WMP up again but still no video I don't think its even attempting to use ffdshow.

:thanks:

[bond]

did enable mp4 support when installing haali?

[jogginman]

yes i did bond.

[bond]

try another directshow player, like media player classic or bsplayer and report what filters it uses to play the file or if it also plays nothing

[Backwoods]

I am having the same problem.

MPC plays the file, AVISynth returns the same error posted above, I set FFDShow to use libavcodec.

I did not however install coreaac + haali's media splitter, or nero vision express.

[bond]

backwoods: what filter get used for playing the file?

[Backwoods]

backwoods: what filter get used for playing the file?

I'm sorry, how can I find out?

[jogginman]

so what next?

:rolleyes:

[jogginman]

when it opens in WMP10 or media player classic it attempts to download a codec but doesn't find a decompressor :scared:

[bond]

try another directshow player, like media player classic or bsplayer and report what filters it uses to play the file or if it also plays nothing<- ! :o

[Backwoods]

<- ! :o

Yes but how?

I tried GraphEdit and it returned an error saying the filter might not be installed. After installing Haali's media splitter the same error came up.

@jogginman
just checking, which version of fffdshow you're using ?
latest (http://m17n.cool.ne.jp/freeware/mpc/)

[jogginman]

I installed the latest ffdshow and media player classic from that link when I try opening an mp4 in media player classic it throws up a warning...
"Media player classic could not render some of the pins in the graph, you may not have the needed codecs or filters on the system."
"The following pins failed to find a connectable filter"

Bond I also tried opening the file in bsplayer and that says "unknown file format ()"

jogginman, Backwoods

you either
- dont have the haali splitter installed
- have the haali splitter installed, but didnt enable mp4 support during installing
- dont have ffdshow installed
- have ffdshow installed, but didnt enable h.264 support during installing
- a combination of the above

I mentioned before I had FFDShow installed but not Haali's Media Splitter, which I have installed recently and this process still doesn't work.

Is there any different settings I should have? All you have said above has been done and checked in my settings before you've posted.

I had it like this, anything else to change?


i dont see the pics :(

Yea they're not coming up for me in IE but Firefox they're fine. I won't upload PNGs anymore and I editing the original post to show GIFs.

Hopefully these pictures can lead to a solution. If not, no problem. Thanks to all who are helping.

Just a random thought, but if you are going to use DirectShow, probably it should be "DirectShow"

"MPEG4 file" has its own checkbox too.

[Japhsoncross]

I have got this kind of problem too, and i don't know the reason. but it can be played in BSPlayer. i guess maybe the head of the video stream from the splitter is not correct?(just my guess :))

maybe it's just me, but i think this is a bit strange :)

[bond]

maybe it's just me, but i think this is a bit strange :)thats used by the nero and haali dshow parser

[SeeMoreDigital]

That's a good suggestion Liisachan,

I totally forgot that MediaPlayer Classic offered this level of filters flexibility. After fiddling with the filters I managed to get Nero filters to decode some QuickTime (Sorenson/QD2) .MOV's...

Had no idea you could change that on the right. The file loads up in AVISynth now. Wow, that was easy. Thank you.
