Sure. Or, what about using a thread-specific variable to store the ID?
From an API standpoint it would mean just one new function, say:
- When called from a video output thread (i.e., from any video callback, typically:
setup), the function would return the ES id set by the decoder upon creation
of the vout.
- When called from any other thread, it would return -1.
