<p class=MsoNormal>Hello,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I’m currently writing a program to replay recorded RTP
video data (typically a transmission of around 25MB/s). So far I’ve
got one thread alternating between filling two send queues with data from the
file and another thread that calls sendqueue_transmit once the associated
buffer returns -1 when calling sendqueue_queue. Whilst one queue is being
transmitted, the other is being filled. I’m certain that it should
take longer to send the data at its original rate than it should to read the
data from the file on the Hard Disk. There are multiple one minute files
that make up a recording since it may be necessary for users to conduct time
jumps and serially seeking through a 20GB + file isn’t on the speedy
side. This method is achieving 24.6 out of the expected 25 frames per
second. Very, very close to the target!<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>My questions are the following:<o:p></o:p></p>
<p class=MsoNormal>Does the sendqueue_transmit method block until all the data
in the queue has been transmitted? Upon attempting to debug this I have
conflicting information.<o:p></o:p></p>
<p class=MsoNormal>Is there a way of adding data to a send queue whilst it is
transmitting (to save swapping queues and the delays this entails)?<o:p></o:p></p>
<p class=MsoNormal>Has anyone written code to perform this sort of playback
before?<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>This program is being written in C#.<o:p></o:p></p>
<p class=MsoNormal>Thanks in advance for any help you may be able to provide.<o:p></o:p></p>
