Hi Ross,
I've been able to create a simple streaming server for my 'modified H.264'
video encoder card and created a simple viewing client in just a couple of days
using the livemedia library, and it might even have been faster if there was
some good documentation available :-). Even so, Livemedia is great, to do this
from scratch would have taken me several weeks. One more question though
regarding packet loss. In a previous post you told me that I can detect packet
loss by inspecting the presentation times at a higher level. I don't see how
this can work properly? Suppose we are streaming live MPEG4 video using RTP
over the internet. If a P frame isn't delivered because one or more of it's
composing packets are lost, the client should stop decoding until it receives a
new and complete I frame. I don't see how the client can detect the packet loss
by simply looking at the presentation time. If the streaming server delivers a
variable framerate then there is no way to know that a frame is lost by looking
at it's presentation time or am I wrong? The only way to detect the frame loss
would be if the higher level had access to the frame's beginning and ending RTP
sequence numbers or am I mistaken? What would be the simplest way to detect
this?
best regards,
Luc Roels
