ffplay RTP: dropping old packet received too late

Gáll Péter
I have a machine which streams live audio to a multicast address:  ffmpeg
-f alsa -i hw:0 -acodec libmp3lame -ab 128k -f rtp rtp://
239.123.13.101:56789. I catch that stream with ffplay: ffplay rtp://
239.123.13.101:56789.It works fine until I stop ffmpeg and start it again.
If I restart ffmpeg (when ffplay still running), I get the error message
from ffplay: RTP: dropping old packet recieved too late. Is there a
solution to "re-receice" the newly started stream, without restarting
ffplay?

Thanks,
Peter

Did you try to use -f rtp_mpegts ?

Yes I tried it. It was a bit better, so it not every time gave me the
error, but most of the time yes, the same error.
The other problem with -f rtp_mpegts, that the first time I run ffmpeg,
ffplay waits ~5secs and just then playy the stream.
