- frontend mode outputs one json dict per line now
- select video stream if input has more than one video(--videostream N)
- update to ffmpeg trunk and new ffmepg api
- use new libtheora encoding api
add new encoding options --soft-target, --buf-delay

[1 to 16778] Set encoding bitrate for video (in kb/s).
.TP
.B\-\-soft\-target
Use a large reservoir and treat the rate
as a soft target; rate control is less
strict but resulting quality is usually
higher/smoother overall. Soft target also
allows an optional \-v setting to specify
a minimum allowed quality.
.TP
.B \-\-optimize
Optimize output Theora video, using a full search for motion vectors
instead of a hierarchical one. This can reduce video bitrate about 5%,

[8 to 2147483647] Set keyframe interval (default: 64).

.B \-d, \-\-buf-delay
Buffer delay (in frames). Longer delays
allow smoother rate adaptation and provide
better overall quality, but require more
client side buffering and add latency. The
default value is the keyframe interval for
one-pass encoding (or somewhat larger if
\-\-soft\-target is used) and infinite for
two\-pass encoding. (only works in bitrate mode)
