Comment (by mav):

 Hi, guys!

 I am trying to implement the HLS adaptive streaming.

 I am disabling unneeded variants with setting AVDISCARD_ALL in
 AVStream->discard.

 But once I enable stream, I cannot disable it again back. The check in
 recheck_discard_flags() is performed only for the first packet.
 Why is it there? Has it something to do with stream timestamps?

 How can I disable fetching of live streams?
