Hi Ross,
Thank you for your response.
Indeed ... I'm struggling with the latency challenge.
My first implementation uses the approach you mentioned. I implemented it
using x264 and it worked fine.
But my requirement is to use the Nvidia Jetson Nano hardware encoder.

I believe I have found a solution.
I implemented a strategy where my circular buffer keeps waiting until a new
frame arrives, similar to a blocking socket read operation. Then everything
goes well.
Then I do not need to worry about the variables anymore, just like expected
from a DeviceSource.

Thanks for the help. I was also able to stream the .mp4 files (created
with the -4 switch) if I renamed them to .m4e, but again with no trick play
functionality.
I shall attempt your solution to convert the .m4e files to TS files and

Dear Ross,

Because I need to send a UDP bytes captured encapsulated in MP4.
Write in file is for testing purposes only.
Needed to know if the VLC played the bytes from the stream rtsp.
I need to get the rtsp bytes, encapsulated in MP4 and send directly by UDP.

Ok Ross,
I looked at the code openRTSP.
I changed the code of testRTSPClient adding QuickTimeFileSink :: createnew.
But the video does not play generated.
Code
//scs.subsession->sink = DummySink::createNew(env, *scs.subsession,
rtspClient->url());
qtOut = QuickTimeFileSink::creat
Use "QuickTimeFileSink" instead of "DummySink". See the "openRTSP" code for
guidance.

But I need to integrate this system into another project.
openRTSP has more features than I need.
I need to capture the video rtsp bytes, encapsulated in MP4, and send UDP.
I believe testRTSPCliente approaches what I need.
Everything is ready, but the video does not play in any player.
Any sugge
The data in "fReceiveBuffer" (for the "video/H264" stream) is a 'raw' H.264 NAL
unit. So you can't write it directly to a ".mp4"-format file.
Instead, I suggest that you use the "openRTSP" application - see
http://www.live555.com/openRTSP/ Note that it has an option "-4" for writing
'stdout'

You realize, I hope, that "openRTSP" doesn't decode
Rather than trying to detect when the RTSP connection closes (which isn't
reliable, and might not happen for a long time after the server disappears), a
better solution is to arrange for a timer to expire if no data arrives within a
certain period of time (e.g., 1 second). This will also detect

I'm trying to use the live555 streaming media to stream video
that we are capturing to file from a camera.
The camera encodes (mpeg4) the video and writes it to a file. At the

If you take a look at the axis api
