Hi Michael,

first of all, thanks for the feedback.

I did not know much about AVOptions... I am looking at them right now, 
and I'll update the patch to use AVOptions.

I see that the whole ffplay.c has to be converted, right? I'll have a 
look, and see if I can find some time for this conversion.

Opss... I knew I was forgetting something... Sorry about that; I'll fix 
the patch and resend.

Ok. I now understand this... I'm going to fix this problem.

I was under the impression that protocol_mask wants to be a bitmask, 
while transport_protocol is a simple constant... Anyway, I see that 
there are some patches changing this code; I'll redo my patch after they 
are applied, and if possible I'll directly use AVTRANSPORT_*, removing 
the RTSP_PROTOCOL_* constants.



			Thanks,
