Bug ID: 916
Summary: avresample_buffer() input buffer should reassure
caller read only
Product: Libav
Version: git HEAD
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: ---
Component: libavresample
Assignee: bugzilla at libav.org
Reporter: kip at thevertigo.com
Created attachment 571

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?).
