Stream.disposition is typed as Disposition but the runtime setter assigns to a C int field, calling int(value). Plain Flag members are not int subclasses, so this raises TypeError. IntFlag members are int subclasses; bitwise / membership semantics are preserved. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Closes #2256
Stream.dispositionis typed asDispositionbut the runtime setter (self.ptr.disposition = value, a Cintfield) callsint(value), which fails on plainFlagmembers because they are notintsubclasses. SwitchingDispositiontoIntFlagfixes the contract: members areintsubclasses, so the conversion succeeds, and bitwise / membership semantics are unchanged.Both
av/stream.py(runtime) andav/stream.pyi(stub) are updated for consistency.
