hello,

I am using crtmp server 402 revision. Streaming live stream to
jwplayer:

externalStreams =
{
{
uri="rtsp://stream01.qt.slamtv.true.nl/slamtv.sdp",
localStreamName="stream0-tcp",
forceTcp=true
},

Audio is starting to play a few seconds earlier than video and later
there is no sync - there is about 1 second delay between the audio and
the video.

How do you solve this problem?

Hello Baikis,

Are you sure about out of sync?

Can you try with Flowplayer and Strobe Media Playback... let us know your result.

Thank you for your fast replies!

I will check regarding the delay - maybe this is the player.
I have another problem - I have ACTI IP camera and I try to stream
rtsp to flash player:

externalStreams =
{
{
uri="rtsp://admin:123...@192.168.1.100:7070",
localStreamName="stream0-udp",

},

in console I have:

camera codec is not supported? I checked the stream using vlc (View >
Stream and media info) and got "Codec: mp4v".

Is it possible to have stream in flash player?..

checked out the latest version (403)

when testing with this setting:

externalStreams =
{
{
uri="rtsp://stream01.qt.slamtv.true.nl/slamtv.sdp",
localStreamName="stream0-tcp",
forceTcp=true
},

everything is ok.. when I change the uri line to

uri="rtsp://admin:123...@192.168.1.100:7070",

I get in console:
