Thanks a lot, I am now able to stream two videos at the same time with
the computer doing almost nothing.
Now, I have to replace the audio of the streams with what is coming
from the FocusRite Scarlett 2i4 2nd generation, and lots of other
things.
Best regards,
Bruno Verachten

Hi Moritz,
Many thanks for the detailed response.

First of all, I don't know if I should continue within this thread or
create a new one. It's all about the same subject, streaming and
recording locally RTMP streams. Please let me know.
So, for the time being, I am able to stream the h.264 encoded stream
with the audio changed thanks to:

Hi!
I am trying to Stop an RTSP STREAMING if connection to IP Camera fails (example
if camera goes offline)
I tried these command with -timeout 3 (to exit after 3 seconds if connection
fails, but it never exists), how this should be done correctly?
ffmpeg -rtsp_transport tcp -i

Paul,
Stereographic projection aka little planet added as both input and output.
Single fisheye is little different.
v_fov is limited to 90°, that's not enough for little planet.
-- I think the d_flip parameter needs some more documentation. What's an
"in-depth" flip?
It swaps back with f

ok, I will test it as soon as it's available at Zeranoe.
I think the field of view isn't correct in the stereographic output.
Here is a script for making really nice test images, for measuring field
of vi

Cant you use here negate filter instead of geq?
oops, yes that would be better. I did search for "invert" and didn't
find it...

Hi Everybody,
I am working on some project involving video streaming using ffmpeg library
source codes.
Although I searched the web, I could not find a proper answer for lossless
encoding with H264.
I have two questions:
1- Constant Rate Factor (crf), preset and map are some of the parameters

Hi Carl,
Thank you for your quick reply.
I am using the source code to develop my own application.
There are command line examples to use with ffmpeg process involving parameters
for crf and map options; but in the source codes I couldn't find these
attributes in avformat or any other structure.
