|
mmx/see optimisation). Enable multiple image size support in ffserver.
|

|
|
external program which opens the .ffm url and writes it to another
|
|
ffserver).
|
|
- added preliminary support for video stream parsing (wav and avi half
|
|
done). Added proper support for audio/video file convertion in
|
|
ffmpeg.
