dc4b2e7d33 rv34: use ff_mpeg_update_thread_context only when decoder is fully initialized 
MpegEncContext based decoders are only fully initialized after the first
ff_thread_get_buffer() call. The RV30/40 decoders may fail before a frame
buffer was requested. ff_mpeg_update_thread_context() fails on half
initialized MpegEncContexts. Since this can only happen before a the
first frame was decoded there is no need to call
ff_mpeg_update_thread_context().

Based on patches by John Stebbins and tested by John Stebbins.

41e1354c10 proresenc: Properly account for alpha plane 
The packet buffer allocation considers the alpha channel as DCT-coded,
while it is actually run-coded and thus requires a larger buffer.

45ce880a9b proresenc: Realloc if buffer is too small 
The buffer allocation may be incorrect (e.g. with an alpha plane),
and currently causes the buffer to be set to NULL by init_put_bits,
causing a crash later on.

So, detect that situation, and if detected, reallocate the buffer
and ask for a sample that shows the problem.
