I added the standard mplayer option to the command line (for mplayer built with live555 library only) - I did not add a new option to the build - look at mplayer documentation. The problem with rtrsp is that the non RealAudio stream were initially defined to use UDP as the comms links were slow (< 56kps). Now rtsp links uses TCP but mplayer will try rtsp oever UDP first and that is the cause of the delay in playing the stations. There is secondary problem with these station in that mplayer initially asks the stations using rtsp protocol and gets audio params and then tries to play with UDP which fails. When mplayer then retries with TCP - mplayer "forgets" some of the audio params it obtained in the initial exchange. By explicitly telling mplayer to use RTSP over TCP and avoiding the failed UDP attempt , avoids the delay and also the audio param are remembered. The same issue can be avoided when using ffmpeg by either use the "-rtsp tcp" option or adding "?tcp" at the end of the URL depending on version of ffmpeg being used. IMO The mplayer 1.0rc2 is stil the best player to use 1. It can play all your streams. 2. It has smaller memory footprint - typically half the other builds. 3. It can be run from a batch file without generating unnecessary output which has to be discarded. Other builds have changed so that if a user chooses "-really-quiet" it must be run from a console - bizarre you must use a console/terminal in order to request no output on the console. 4. It supports use of writing a wav format to a stream. Other builds will not allow a waveheader to be written to a stream and so all stream must be resampled to a common format as there is no way to communicate original streams audio parameters. This will be unnecessary extra load on processor and also unnecessary resampling. > > Also if you do not mind, can you tell me how to pipe the output of > mplayer directly into SB for testing from the command line. for example > mplayer rtsp://livestreaming.ositcom.net:1935/vdl/vdllb -ao PCM #PIPE# > $FILE$ > this way I can test with the new mplayers... > #PIPE# is substituted by the detailed of the named socket created by socketwrapper which is used to provide the communication path between LMS, mplayer, Flac and back to LMS. Not relevant on a command line. $FILE$ is subsituted by LMS to the file name being requrested . Again not relevant to command line. Read the mplayer documentation on the "-ao" option . "-ao pcm:waveheader:file=test.wav" writes the output in WAv format to the file test.wav If you play back a wav file - the player will pick up the audio stream details (e.g. freq, sample size, no channels, bits per sample, endian) from the WAV file header. "-ao pcm:nowaveheader:file=test.pcm" writes the raw PCM output to the file test.pcm. To play back you will need to explicitly supply all pcm audio stream details. Read the mplayer documentation for "-af" if you want to do resampling or other changes to audio streams. > I did more work on your idea -rtcp-stream-over-tcp.

It will play on a clean PlayReal installation. Forget RealAudio as it is not a test of anything - it uses a different RTSP and different codec. The Plugin knows the RealAUdio RTSP and so can enable burst mode loading of stream for fast startup and implements "seeking" to a specific time in the stream. It is out of date for BBC. If you want to play BBC - play the WMA stream equivalent as it will play directly on player. Regarding the other 3 rtsp URLs. The PlayReal plugin is set up for RealAudio which is a different RTSP and so you need a different plugin - not just a different conf file. Attached is a plugin which I used to use for playing strange streams. It enable passing a URL direct to mplayer and feeds output of mplayer from LMS. Just unzip and manually copy into the "server/Plugins" directory in the Squeezecenter. You will need to copy mplayer into the Xplay\Bin directory. The custom-convert.conf is setup for 1.0rc4 mplayer but I have included another convert.conf file for the later mplayer build if you really want to use them. To play a stream just prefix the stream by "xplay://" and use "Tune-in" or make a Favorite. e.g "xplay://rtsp://mobilestreaming.itworkscdn.com/radioorient/radioorient" . The Plugin strips the "xplay://" from the URL before passing it to mplayer. The plugin does not know what application is used to "play the stream" so it could be changed to ffmpeg, avconv, vlc ... +-------------------------------------------------------------------+ |Filename: Xplay.zip | |Download: http://forums.slimdevices.com/attachment.php?attachmentid=15136| +-------------------------------------------------------------------+ ------------------------------------------------------------------------ bpa's Profile: http://forums.slimdevices.com/member.php?userid=1806 View this thread: http://forums.slimdevices.com/showthread.php?t=90070 _______________________________________________ plugins mailing list plugins@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/plugins
