-Subject: [PATCH] flxdec: rewrite logic based on GstByteReader/Writer
-
-Solves overreading/writing the given arrays and will error out if the
-streams asks to do that.
-
-Also does more error checking that the stream is valid and won't
-overrun any allocated arrays.  Also mitigate integer overflow errors
-calculating allocation sizes.
