impossible. Initially I was thinking this is an Internet problem but it is not
as other players like VLC for example handle it just fine. So I run a http
sniffer and noticed that ffplay generates a huge number of HTTP GET range
requests. VLC generates only one. So I guess the problem is coming from this
huge number of requests which make the reading very slow. Is there any way this
can be avoided for this kind of online media?> > > > -- > Benoit Fouet> Purple

Thanks for your advice. I have updated and it initially works. The URL is
played just fine for about a minute or so. At some point (after it has approx
downloaded 4Mbs) it again starts making huge number of GET requests one after
another and each one reads no more than 100K. As result the playing almost
stops and gets very very slow. This happens in ffplay too ...
Regards,
Nick
