  • FFMpeg and WebM/VP8

    25 novembre 2011, par Anand Suresh

    I am trying to use ffmpeg and ffserver to stream VP8 video.

    I am using the following command to start FFMpeg :

    ffmpeg -v 9 -loglevel 99 -f x11grab -s 1440x900 -r2 -i :0.0 -f webm http://localhost:8090/feed1.ffm

    The above command abruptly terminates generating the following error :

  • Free video file converter for c#

    29 novembre 2011, par Richard77

    I'm looking for a library in C#(not commandline) that converts video files' from one format to another.

    While googling, I've seen that many people have asked this question before. Unfortunately those questions were asked years in the past. The most recent of them was aked in april of 2010.

    I've read a lot about FFMPEG, but I don't see any tutorial on how to use that library in C#.

    Please, help with sample codes if possible.

    Thanks for helping
