We now use "const" for the chunk buffer pointer returned by GetNextChunk, because the buffer is not supposed to be modified by the codec. size_t is used for the size where applicable. This matches BMediaDecoder. git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@13361 a95241bf-73f2-0310-859d-f6bbb57e9c96
