|
mmx/see optimisation). Enable multiple image size support in ffserver. |
|
- added multi live feed support in ffserver. |
|
- suppressed master feature from ffserver (it should be done with an |
|
external program which opens the .ffm url and writes it to another |
|
ffserver). |

|
done). Added proper support for audio/video file convertion in |
|
ffmpeg. |

|
|
|
- added stereo in mpeg audio encoder. |
|
|
|

|
- added 'high quality' mode which use motion vectors. It can be used in |
|
real time at low resolution. |

|
bitrates and large gop size. |
|
|
|
