On a deeper analisys I think a better fix would be
exposing a protected setParsingComplete() method
in MediaParser and have that call waitIfNeeded.
Doing so we'd make sure the "ifNeeded" check is only
performed when the important conditions actually change:
- Buffer pushed to
- Parsing completed
I'm working on a patch for testing if you don't beat
me to it. The patch would also make waitIfNeeded()
and _parsingCompleted private.
