symbian下ffmpeg编程。。废了好大劲下下来的！。

This is an experimental movino receiver application for use on linux.
Currently, it can feed the video stream to V4L, forward the stream to
another movino receiver or save the stream to a file.

Most of the dependencies mentioned in the file COMPILING
in the main directory are not needed for this application. Ffmpeg
can be added, as described in that file, to be able to decode
mpeg encoded frames and to be able to encode flv and mpeg video.
Ogg/theora can also be added, for encoding. (If ogg/theora isn't
desired, edit the Makefile and set HAVE_THEORA to no.)

This application uses libbluetooth-dev by default. If this is not
desired, edit the Makefile in this directory and set HAVE_BLUEZ to no.

Running the application with "./movino -h" gives a short summary of the
available command line options. They are:

	-i port		Sets the port for receiving stream data from
			clients. (Default 30710)

	-p password	Sets a simple password required for connecting
			to the receiver application.

	-b		Listen for connections over bluetooth.

	-t		Listen for connections over TCP/IP.

	-v device	Feed video to the given V4L device.

	-o host[:port]	Forward the content stream to the given host
			(and port). If the forwarding connection is
			broken, it can only be reconnected by restarting
			the app (at the moment).

	-s filename	Save the video stream to files with the given
			base filename. An index number and extension
			is appended to the file name.

	-f format	Chooses which format the app encodes to.
			Currently, the only supported alternatives
			are ogg, flv and mpeg. (Default ogg)



V4L
---
Feeding video to V4L requires the AVLD video loopback module,
available at http://allonlinux.free.fr/Projets/AVLD/.
Compile and install the avld module, and load the module
with these parameters:

modprobe avld palette=1 fps=0

A width and height for the video device can optionally be specified, too,
as described on the AVLD page. The width and height can be changed without
reloading the module, too, but this shouldn't be done while movino or
any application using the device is running.


When avld is loaded, launch the movino application like this:

./movino -b -t -v /dev/video0

This seems to work with skype, at least, and mplayer is able to view
the video stream from the video device, if it is given the correct
parameters. Mplayer can view the stream with a command line like this:

mplayer tv:// -tv "driver=v4l:device=/dev/video0:noaudio:outfmt=uyvy"
