Your encoder(s) is not keeping up. You will notice that in the stderr output
that they are reporting approx 17fps. You input is 29.97. So your input buffer
is filling up till it ove

Dear all
I am seeking for helps with my issue of losing audio streams when receiving
signal from Decklink SDI input, on rtmp outout, the audio stream was
missing after couple seconds, but I check on SDI then audio was normal.
Below is my command :
ffmpeg -format_code Hi59 -video_input sdi -audi
Hi,
You have dual core cpu, you show that with 1 ffmpeg it use 77% of one
core (so like ~40% of cpu), with 2 ffmpeg it use 90% of first and second
core (so like 90% of cpu), with 2 ffmpeg it uses almost all cpu, so no
wonder that with 3 ffmpeg it slowing down because it need 1,5 more cpu,

You will have to label the final overlay output e.g. [v] and then map it as
well-map "[v]"

Hi,
i develop a C++ application which generate a FFMpeg command to create a
mozaic of 3 videos.

The exported video duration is equal to the longest source video (i have

How many CPUs / cores are you using?
Transcoding FullHD in SD, without using any hardware accelleration for more
than two channels seems a quite huge load.
It can be simply your CPU cannot go fast enough
