I think the email was for Luca B, but I had a look at the patches
anyway :)

I think the first one (rtsp_eintr.txt) looks good.

The second one (rtsp_eagain.txt) is good in theory, but I think it is
not complete: as far as I know, the rtp input sockets are not set as
non-blocking, so the block of code added by the patch will be used only
if the 100ms timeout fires (so, the read operation is not really "non
I think that a call to ff_socket_nonblock() should be added to then open
function (maybe to udp_open()?) if AVFMT_FLAG_NONBLOCK is set.
