converting x/h.264 to xvid/divx

[slider17]

hi

just as the title says, is there a way of converting from .264 to either xvid or divx. the source is a nero recode encoded h.264 file (mp4).

any suggestions??

Hi Slider17!

If you have a working MP4 Splitter + Decoding Filters installed you could use Avisynth with this script: "directshowsource("movie.mp4",convertfps=true)"
The convertfps=true is just to be sure everythings in sync. Open the Script in VDub and you're set to transcode to XVid (hopefully).

thanks for the reply eMotion

i tried creating a AVS script with the following details:

name of file: test.avs
contents of file:

directshowsource("C:\TEST\EPL.mp4",convertfps=true)

tried opening it in virtualdub 1.6.5 but it gave an error:

Script error: directshowsource does not have a named argument "convertfps"

what does this mean??

i mainly use VLC to play back .mp4 encoded files.
I used to have ffdshow, but recently got rid of it. do i need this in order to open the .avs script file??

thanks

It means you need to install avs v2.56 rc1.

You will obviously need a h264 directshow decoder to use directshowsource.

ok ive hit another snag.

i just installed ffdshow for my system, but for some reason its now not playing .mp4 files in wmp. usually that wouldnt be a big issue as i use vlc for that, but as stated above i need a directshow decoder in order to get the avs script to work.

i have made sure that h264 decoding is set to libavcodec in the 'video decoding' settings, but to no avail.

any ideas.

do you have an mp4 splitter installed? (try Haali's media splitter)

[slider17]

yep +2 characters :S

[slider17]

btw, what is a media splitter (whats its purpose)??

[slider17]

ok i instaled the media splitter app, and wmp is now only playing the audio and no video is being displayed. i see that the ffdshow and mediaspliter icons are being displayed at the bottom right of my screen (tray icon).

btw, i tried opening the avs script in vdub but its now saying: "No video stream found"

im guessing its because it cant decode the video.

btw, what is a media splitter (whats its purpose)??A media file consists normally of multiple layers. You have the video and audio data that needs to be decoded, but you also need a layer that tells you what piece of data is what, which decoder is needed and when it needs to be played. A splitter is needed to read this data.

Or, simpler said, the splitter interprets the container data.

Could be Haalis splitter doesnt create a video pin. Normally WMP would complain if it cant complete a filter graph. You can try other mp4 splitters, but i wouldnt know where to get them.

oh well, if any one knows a possible solution please post here.

thanks

You could deinstall haali's splitter. Make sure that's uninstalled - the mp4-file shouldn't work in wmp anymore. Then you can download free Quicktime 7 which comes with an mp4 splitter (not 100% sure, but i think). After installing QT7 you will perhaps have to set the mp4-decoding in ffdshow again.

wishes, chris

ps.: for best mp4-decoding support make sure you do have the latest ffdshow installed!

[slider17]

i have the sept 20th version of ffdshow.

i already have quicktime 7 installed.

funny thing is, that before i uninstalled ffdshow awhile back, mp4 used to work fine in wmp (both video and sound). not anymore. very strange.

ok ive got it working now.

i installed the new version of nero premium 7. the filters there took over the preceeding ones and started playing .mp4 files in wmp fine (both audio and video).
but that still didnt get vdub working.

so i downloaded the latest build of ffdshow (30th of sept) and installed it with default settings. finally wmp started using ffdshow to play back .mp4 files.
so then i tried vdub, and the damn thing worked!!

woo-hoo.

thanks for everybody who replied and helped me with this problem.

thanks again
