I said to keep the ID as meta in the format, so iwe can still match TS ES. But stop using it as track identifier in LibVLC and input interfaces...

If ES is a reference counted object, the pointer itself is intrinsically guaranteed to be temporally unique - even in the racy cases of ES deletion or addition and even across demux slaves.
