Avisynth: Loading ogm files?

hello everyone

long time i have to deal with an ogm video. i remember having succeed but now i need help again.

when i load this script on tmpgenc, it starts encoding but just a black screen.

Code:

DirectshowSource("C:\video3divx5.ogm", fps=30.000)

BilinearResize(320, 190, 4, 0, 632, 352)

aSharp(2, 4)

AddBorders(16, 17, 16, 17)

TextSub("C:\video3.srt")

thank you so much :wink:

Are you sure you have the codec used for the video that is in the ogm ?
Let remember that ogm is just a container, not a codec. The video in the container can be xvid, divx or other thing.

Note: you can also open it into virtualdub mod and save it as avi. This will probably remove the audio but who cares ?

thank u, Dialhot

yes, i know that ogm its just a container and i think i have the exact codecs because i can play it in the windows media player with no problems.

That's definitely not an answer. BTW this time I did a mistake, this is not a codec that you miss but a directshow filter. Open Graphedit, drag your OGM into it and look at how your file is rendered. You will probably have an error there.

No error in the rendering so you should have no problem.

1/ Try to go into the DirectVobSub configure panel, in the "General" tab, "Loading" section, select "Load when Needed".

2/ Go into the preview of tmpgenc (after load the avs, menu File -> Preview). Do you have a black screen there also ?

3/ Play the avs in a media player, what yo you have ?

4/ add a "Info()" at the end of the script and redo the point 2 and 3. What is the colorspace indicated on the video ?
