Save the old output configuration (if it has been used
successfully) when trying a new configuration. If the new configuration
fails to decode, restore the last successful configuration.

This option is the stream identifier to play or to publish.
Sometimes the URL parser cannot determine the correct
playpath automatically, so it must be given explicitly
using this option (ie. -rtmp_playpath).

This option is the name of application to connect on the RTMP server.
Sometimes the URL parser cannot determine the app name automatically,
so it must be given explicitly using this option (ie. -rtmp_app).

Without these, the expansion contains things like --1 with
some compilers resulting in build errors.

Fixes crashes when using biweight on win64.

Prevents it from referring to the rest of the list.

Prevents extensive buffering when overlaying a single picture.

This is the first step towards supporting complex filtergraphs with more
than one input and/or output.

It more properly belongs to output, not input.

Always take it from lavfi. This way we don't need a clearly defined
corresponding input stream.

This is a more proper place for them, since they store parameters of the
input, not output, stream.

This way we don't require a clearly defined corresponding input stream.

The result for the xwd test changes because rgb24 is now chosen instead
of bgra.

Right now, they are arrays of structs, reallocated when new
streams/files are added. This makes storing pointers to those structs
harder than necessary.

They are globals, no point in pretending they are not.

Switch from changing global values to defining a separate C style
and add appropriate settings for indenting assignments that span
more than one line.

Call mov_read_close when mov_read_header fails.

Instead of allocating over the original, free first. MOVStreamContext
is zero initialized so no double free will occur. Same style as other
fixes for the same problem in this file.

If coefficient A is 12-bits xixed-point number "X", then the other
coefficient is (1 << 12) - X, not (1 << 12) - X - 1.

The user submitted variable in this function is frame, not buf.

There is no point in storing the value in a variable, since it is not
used anywhere else in the decoder.
