This makes the code simpler to understand, though it results in an
unnecessary call to avcodec_find_decoder() if the stream won't be
decoded.

The file is going to contain the amovie source, so give it a less
specific name.

Reduce code duplication.

The table is automatically generated from the definition of enum CodecID in
avcodec.h and contains the name of all known codecs, even those for which no
encoder nor decoder exists or is enabled.

The table is queried using the avcodec_get_name function.

If CONFIG_SMALL is true, the table is not compiled in; the avcodec_get_name
looks for names in the list of available decoders and encoders.

This is required for the pending lavfi indev extension, also
consistent with the video buffer sink.

Allow factorization for the pending work on the audio movie source.

libmp3lame if available, ac3 otherwise.

libvorbis/libx264 for video if available, otherwise ac3/mpeg4.

Clarify with an example what the user should use instead of the
deprecated (and no longer working) -s/-pix_fmt options.
