/*
|
|
* Here is a summary on how this works:
|
|
* - The VoipCalls will call add_rtp_packet() every time there is an RTP
|
|
* packet
|
|
* - add_rtp_packet() will add the RTP packet in a RTP stream struct, and
|
|
* create the RTP stream if it is the first RTP in the stream.
|
|
* - Each new RTP stream will be added to a list of RTP stream, called
|
|
* rtp_streams_list
|
|
* - When the user clicks "Player" in the VoipCall dialogue,
|
|
* rtp_player_init() is called.
|
|
* - rtp_player_init() create the main dialog, and it calls:
|
|
* + mark_rtp_stream_to_play() to mark the RTP streams that needs to be
|
|
* displayed. These are the RTP stream that match the selected calls in
|
|
* the VoipCall dlg.
|
|
* + decode_rtp_stream() this will decode the RTP packets in each RTP
|
|
* stream, and will also create the RTP channles. An RTP channel is a
|
|
* group of RTP stream that have in common the source and destination
|
|
* IP and UPD ports. The RTP channels is what the user will listen in
|
|
* one of the two Audio channles.
|
|
* The RTP channels are stored in the hash table rtp_channels_hash
|
|
* + add_channel_to_window() will create and add the Audio graphic
|
|
* representation in the main window
|
|
* - When the user click the check box to listen one of the Audio channels,
|
|
* the structure rtp_channels is filled to play one or two RTP channels
|
|
* (a max of two channels can be listened at a given moment)
