It doesnt matter which applies so much, what matters is that the variable
where and are completely undocumented and i have absolutely no idea what
they are without "reverse engeneering" it out of the code.
no matter what you do know about the variable you are not writing it down,
its just a black box that receives a completey different and incompatible
name in each iteration of the patch.

also for example stream_id&1 == keyframe shows immedeatly that the variable
cannot be _any_ id or type of stream or set of streams. Its lowest bit is
clearly a keyframe flag. But then again this MUST be documented in the
variable name or doxy for it not found out by finding a 
if(stream_id&1) keyframe=1; or something like that

either it is a stream type or an id of a stream or an id of a set of streams
or a index into a list of streams or something entirely different.
