The only "mess" is in the raw decoder which tries to avoid copying
of which this is only one issue (demuxer packets magically changing
context when the decoded image is modified is another for example).
I sent a patch, however it really should be done a bit cleaner.

This "bug" can only appear in codecs that do not use get_buffer,
which limits the issue quite a lot IMO.
