4fe9e2fc16 avformat/rtsp: don't forget to call ff_network_close() on error
In sdp_read_header() some ff_network_close() calls were missed.

Also in rtp_read_header() update comment to explain why a single
call to ff_network_close() is enough to cover all cases even if
sdp_read_header() returns an error.

As per the docs network initialization is required before ff_url_join().
Furthermore, because the ff_network_init() was skipped, this makes
one additional call to ff_network_close() if the stream exits without
errors.

3a2b786db0 avformat/matroskadec: adjust the cluster time to the track timebase
The Block timestamp read in matroska_parse_block() is in track timebase and is
passed on as such to the AVPacket which uses this timebase.

In the normal case the Cluster and Track timebases are the same because the
track->time_scale is 1.0. But when it is not the case, the values in Cluster
timebase need to be transformed in Track timebase so they can be added
together.
