ee37d5811c rtpproto: Allow specifying a separate rtcp port in ff_rtp_set_remote_url
A separate rtcp port can already be set when opening the rtp
protocol normally, but when doing port setup as in RTSP (where
we first need to open the local ports and pass them to the peer,
and only then receive the remote peer port numbers), we didn't
check the same url parameter as in the normal open routine.

c7e921a54f avopt: Check whether the object actually has got an AVClass
AVIOContext has got an av_class member that only gets set if
opening the context using avio_open2, but not if allocating a
custom IO context. A caller that wants to read AVOptions from
an AVIOContext (recursively using AV_OPT_SEARCH_CHILDREN) may
not know if the AVIOContext actually has got a class set or not.

e1d5b24476 hls: Store first_timestamp in units of AV_TIME_BASE
When first_timestamp was stored as-is, its actual time base
wasn't known later in the seek function.

Additionally, the logic (from 795d9594cf) for scaling it
based on stream_index is flawed - stream_index in the seek
function only specifies which stream the seek timestamp refers
to, but obviously doesn't say anything about which stream
first_timestamp belongs to.

In the cases where stream_index was >= 0 and all streams had the
same time base, this didn't matter in practice.

Seeking taking first_timestamp into account is problematic
when one variant is mpegts (with real timestamps) and one variant
is raw ADTS (with timestamps only being accumulated packet
duration), where the variants start at totally different timestamps.

c110cbf6b5 hls: Create an AVProgram for each variant
Without the information, an application may choose audio from one
variant and video from another variant, which leads to fetching two
variants from the network. This enables av_find_best_stream() to find
matching audio and video streams, so that only one variant is fetched.

9d64f23629 hls: Respect the different stream time bases when comparing dts
Also adjust the streams timestamps according to their start
timestamp when comparing. This helps getting correctly interleaved
packets if one stream lacks timestamps (such as a plain ADTS
stream when the other variants are full mpegts) when the others
have timestamps that don't start from zero.

This probably doesn't work properly if such a stream is
temporarily disabled (via the discard flags) and then reenabled,
and such streams are hard to correctly sync against the other
streams as well - but this works better than before at least.

The segment number restriction makes sure all variants advance
roughly at the same pace as well.

cdd2d73d31 hls: Don't check discard flags until the parent demuxer's streams actually exist
If passing the end of one segment while initializing the
chained demuxer, the parent demuxer's streams aren't set up

eb33ba04e0 hls: Return all packets from a previous variant before moving on to the next one
This serves as a safeguard; normally we want to use the dts
comparison to interleave packets from all active variants. If that
dts comparison for some reason doesn't work as intended, make sure
that all packets in all variants for a certain sequence number have
been returned before moving on to the next one.
