The new flags parameter allows to specify if the video ref to add
should overwrite the cache, if the flag is not set vsrc_buffer will
complain and abort; otherwise it will clean the already cached video
ref before to overwrite it, thus avoiding a leak.
Avoid to add frames to the vsrc_buffer in the case ist->pts <
start_time, as these frames are unused (and never released). In
particular this condition is verified with commands of the kind:
ffmpeg -i INPUT -ss TIME OUTPUT
Also allow a minor simplification.
Make ff* tools only accept opt_* functions taking two arguments.
The distinction between functions with one and two arguments is quite
pointless. Simplify parse_options() code.

Fixed another dereference in the RTSP code.
Removed a useless variable.
Changed an unnecessary looping assignment to a simple assignment suggested by
Maksym.
Added fixes and tweaks suggested by Maksym Veremeyenko [verem@m1stereo.tv] and
Clément B.
Grow the file and stream list in opt_input_file() instead of creating it
all at once in transcode(). This is simpler and will be useful for
following commits.
Currently, the url_interrupt_cb callback will abort all IO
after the first received signal. This makes the output files
from e.g. the mov muxer to be unreadable if the transcode is
aborted with ctrl+c.
After this patch, the first signal cleanly breaks out of
the transcoding loop, but won't forcibly abort all IO.
After the second signal is received, the url_interrupt_cb
callback will abort all IO.

The new function accepts a slightly more intuitive order of paramters,
and returns an error code, thus allowing applications to report a
meaningful error message.
The new function is a wrapper around
av_vsrc_buffer_add_video_buffer_ref(), and allows to simplify the act
of pushing AVFrame data to the source buffer.
Rename av_vsrc_buffer_add_frame to
av_vsrc_buffer_add_video_buffer_ref(), and change its inteface to make
it accept in input an AVFilterBufferRef rather than an AVFrame.
This way the interface can be used without requiring the
inclusion/installation of libavcodec headers.
Redesign the way -aspect option is handled. This is done by making
ffmpeg read the sample aspect ratio set in the corresponding input
stream by default, and overriding it using the value specified by
-aspect.
If the output display aspect ratio is specified with -aspect, it is
set at the end of the filterchain, thus overriding the value set by
filters in the filterchain.
This implementation is more robust, since does not modify the
filterchain description (which was creating potential syntax errors).

Another aspect ratio fix try. This leaves the setdar addition at the end
(preferred by people).
(Cherry-pick e7c7b0d000)
This fixes several bugs like multiple outputs and -aspect mixed with -vf

Iam not sure this is the best way to implement it, but its the simplest
and keeps the code seperate from the application. Keeping ffmpeg.c
simple and not requireing user apps to duplicate this code.
