This library intends to follow the RTSP RFC document (2326) to allow for working with RTSP servers. By way of rtp, you can either inspect the RTP packets as they come across the wire or use the file that the data got saved to.
For more information:
-
All standard RTSP methods supported except REDIRECT.
-
Captures RTP data to a file, or yields if a block is passed to #play.
-
One client object can only handle 1 stream; use a client per stream until this functionality gets implemented.
-
Only handles unicast, TCP RTSP communication.
-
RTSP exceptions are all {RTSP::Error}s.
RTSP::Client.log? # => false RTSP::Client.log = true client = RTSP::Client.new "rtsp://64.202.98.91/sa.sdp" client.server_uri # => #<URI::Generic:0x00000100ba4db0 URL:rtsp://64.202.98.91:554/sa.sdp> client.session_state # => :init client.cseq # => 1 client.connection.do_capture # => true client.connection.interleave # => false client.connection.timeout # => 30 client.capturer.ip_addressing_type # => :unicast client.capturer.rtp_port # => 6970 client.capturer.capture_file # => #<File:/var/folders/tg/j9jxvvfs4qn9cg4vztzyy2gc0000gp/T/rtp_capture.raw-59901-1l8dgv2> client.capturer.transport_protocol # => :UDP response = client.options response.class # => RTSP::Response response.code # => 200 response.message # => "OK" client.cseq # => 2 response = client.describe response.body.class # => SDP::Description response.content_type # => "application/sdp" response.server # => "DSS/5.5 (Build/489.7; Platform/Linux; Release/Darwin; )" client.aggregate_control_track # => "rtsp://64.202.98.91:554/sa.sdp/" client.media_control_tracks # => ["rtsp://64.202.98.91:554/sa.sdp/trackID=1"] client.cseq # => 3 response = client.setup(client.media_control_tracks.first) response.session[:session_id] # => 7098486223178290313 client.session[:session_id] # => 7098486223178290313 client.cseq # => 4 client.session_state # => :ready response = client.play(client.aggregate_control_track) response.range # => "npt=now=" resposne.rtp_info # => "url=rtsp://64.202.98.91:554/sa.sdp/trackID=1" client.session_state # => :playing # Wait while the video streams sleep 5 client.pause(client.aggregate_control_track) client.session_state # => :ready # Wait while the video is paused sleep 2 client.teardown(client.aggregate_control_track) client.session[:session_id] # => 0 client.session_state # => :init # Check the streamed file's contents puts client.capturer.capture_file # => (Lots of data)
As of RTP 0.1.0, you can now inspect and use packets as they come across the wire:
client = RTSP::Client.new "rtsp://64.202.98.91/sa.sdp" client.describe client.setup(client.media_control_tracks.first) payload_file = File.new('rtp.data', 'wb') client.play(client.aggregate_control_track) do |packet| puts "packet is a #{packet.class}" puts "RTP seqence: #{packet.sequence_number}" puts "RTP payload type: #{packet.payload_type}" # Let's save the payload data while we're at it... payload_file.write(packet.rtp_payload) end payload_file.close
Take a look at the RTP::Packet docs for more information.
RTSP also provides a rtsp_client executable that allows a little talking to an RTSP server.
Knowing which tracks are available on the server can help you determine which tracks to use in your programmatic use of an RTSP::Client object to try to play. Show the available aggregate control track and media control tracks:
$ rtsp_client --show-tracks rtsp://64.202.98.91/sa.sdp
Or if you want the entire SDP description from the server:
$ rtsp_client --describe rtsp://64.202.98.91/sa.sdp
And then, of course, pull a stream (this assumes you SETUP the first media track and call play on the aggregate track):
$ rtsp_client --stream rtsp://64.202.98.91/sa.sdp
As usual, get help by:
$ rtsp_client --help
