Assign stream index on outgoing RTP packets (#182)

Browse Source

* Assign stream index on outgoing RTP packets (#5)

* Correctly assign mindex on outgoing rtp packets

Previously mindex was not set and defaulted to zero. This lead to most packets
getting dropped because of sequence number reuse when streaming both audio and
video. This reorders the SDP entries for video and audio so that video is first
in both a video-only and a audio+video configuration. This means that the mindex
for video packets should always be zero, and for audio (if present) should
always be one. This assumes there will never be an audio-only configuration.

* Adjust comments

* Add preprocessor conditional to guard packet.mindex setting

The mindex field wasn't added to the janus_plugin_rtp_packet until Janus 1.0, so this change adds a precompiler check to ensure JANUS_PLUGIN_API_VERSION is >= 100 before assigning a value to the mindex field.

* Preserve audio-then-video ordering for Janus 0.x
