Hi, >I have problems using Mplayer (MPlayer SVN-r30100-snapshot-4.4.1) with ALSA. > >I want to play a RTP stream accessed through RTSP.

You will generally want to use Ethernet or fast >>PLC for streaming, which are way more reliable (and fast) than wireless >>communication. A little googling on that topic will tell you the same! >>just my 2 cents, >>Seb. Thanks for you answer, I agree with you but it's for a demonstration and the demonstration will be better using Wifi than Ethernet :). Moreover, it works when I use OSS (but sometimes I have problem of multiple access to /dev/dsp file so I prefer use ALSA). >>Does -cache help? >>Carl Eugen Thanks too, I see no improvement using -cache option : ./mplayer rtsp://mylink/monfichier_mp3.mp4 -ao alsa -ac ffmp3 -cache 8192 -cache-min 4 Message is always the same when sound is crashing : [AO_ALSA] Write error: Broken pipe Audio : 100.1% [AO_ALSA] Trying to reset soundcard. Another indication : when I use ALSA, pourcentage indicated (100 * audio_time_usage / mpctx->delay) is always about "100%". When I use OSS, the value is smaller : about "10%" maximum. I have noticed that when I use ALSA, it tries to decode much data at the same time than when I use OSS. Maybe, there is a link ? Thanks in advance, Pierre
