Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
When running the cleanup in rtmp_close on failures in rtmp_open,
we can in rare cases end up using rt->playpath, assuming that it
is still set.
The crash could happen if we hit the fail codepath in rtmp_open
while publishing (rt->is_input == 0) with rt->state set to
a value > STATE_FCPUBLISH.
This would normally not happen while publishing; either we have
an error (and rt->state <= STATE_FCPUBLISH) or we reach
rt->state = STATE_PUBLISHING, and then we also return successfully
from rtmp_open.
The unexpected combination of states could happen if the server
responds with e.g. "NetStream.Play.Stop" while expecting
"NetStream.Publish.Start"; this sets rt->state to STATE_STOPPED,
which also fulfills the condition "> STATE_FCPUBLISH".
We don't need to free the rt->playpath/tcurl/flashver strings here;
they're handled via AVOption, and thus are freed automatically when
the protocol instance is freed (that's why they aren't freed
manually within the rtmp_close function either).
We also don't need to free the AVDictionary with options; it's
owned by the caller.
A smaller fix would be to just call rtmp_close before freeing
the strings and dictionary, but as we don't need to free them
at all, let's remove that redundant code.
