|
|
|
|
|
<lists@reserv.at>, but changed completely since we use a format
|
|
|
|
|
instead of a protocol).
|
|
|
|
|
|
|
|
|
|
version 0.4.2:
|
|
|
|
|
|
|
|

|
|
|
|
|
missing. MSMPEG4 support is complete.
|
|
|
|
|
- added prototype MPEG1 decoder. Only I and P frames handled yet (it

greenish).
|
|
|

|
|

|
|
|
|
|
(default=log). suppressed redundant -hq option.
|
|
|
|
|
- added options -acodec and -vcodec to force a given codec (useful for
|
|
|
|
|
AVI for example).
|
|
|
|
|
- fixed -an option.
|
|
|
|
|
- improved dct_quantize speed.
|
|
|

|
|
stream support to ffmpeg.

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).
|
|
|
|
|
- added preliminary support for video stream parsing (wav and avi half
|
|
|
|
|
done). Added proper support for audio/video file convertion in
|
|
|
|
|
ffmpeg.
|
|
|
|
|
