[libav-devel] [PATCH] avresample_buffer() input buffer should reassure caller read only.

Hey folks,

Please find enclosed a patch to ensure avresample_buffer() caller's
input buffer will not be modified.

Although the task of patching all of libav for const correctness is
beyond my time at present, the attached is small patch to at least
allow libav client code to compile cleanly when calling
avresample_buffer() with an input buffer it needs to be reassured will
not be modified.

From what I could see, the changes needed were only minor syntactical,
so I hope there wasn't something more fundamental / deeper why
avresample_convert() could potentially need to tamper with the input
buffer (e.g. dependent ff_audio_data_init's read_only parameter?).
