I'm designing an application, which has to read some video file in specified format (I want to read only: *.avi, *.mpg, *.mp4) and save its in the same format. I have read successfully files from *.mp4 containers and *.avi containers, but unfortunately I can't find proper classes for another containers...
Below I'm attaching a short table, what I can't find. Could you tell me where I can find classes signed as "???" ?
It's very urgent for me.
Thank you for any help.
