Hello,
First of all, I'd like to thank everyone involved in the project. This
is quite helpful for newbies like myself.
I have a server streaming H.264 and AAC. The video resolution is 1080i @
29.97 fps. The bit rate is around 5 Mbits/sec.
I'm currently working on the client side. I'm using the office LAN to
test. Both server and client are connected at 1 Gb/s. I also tested
using a D-Link 1 Gb/s managed switch.
I based my code on the H.264 tutorial.
I get corruption once in a while. The H/W encoder is configured to
generate one IDR and 14 forward frames, no backward frames (I, P and B
in mpeg2 terminology). I'm not sure of the H.264 terminology.
What I see is that the reference frames are quite large > 150 KB while
the other frames are around 15 KB.
Most of the times, the client is called with the right size. Once in a
while, I will be missing part of a IDR or even the whole reference
frame. If I use Wireshark on the client side, I see that I'm receiving
the "missing" packets. I haven't digged in the code to investigate yet!
On the server side, when the frame is larger than the destination
buffer, I copy as much as I can. The remaining data will be copied when
doGetNextFrame is called again.
Incomplete parts have the right presentation time but I set the duration
to 0.
The last part has the same presentation time but I set the duration
according to the right frame rate.
Any clues you might think of? Where should I start looking? NTSC @ 2
Mb/s is much more stable.
Thank you!
Georges
