Hi
I try to put on the text image.
ffmpeg -re -rtsp_transport tcp -i
rtsp://admin:xxxxx@192.168.2.25:554/Streaming/Channels/1 -f image2 -loop
1 -i C:\k\v\T\A.bmp -filter_complex "overlay=10:10" -vcodec libx264
-pix_fmt yuv420p -f flv rtmp://a.rtmp.youtube.com/live2/x-x-x-x
the image file size is ~200kb, lot of time to write to disk, and ffmpeg
do not open some times, and the last image show static.
that method is good for a short time, but rather this is good show logos
on the video
and I do not put videocard the pc, but it is a notebook.
I did not say, the text information change per second.
I like to made example football video brodcasting, is shown at the top
of the image the result, time, and others ( flags..)
Thanks
Robert

Hi, we are also streaming a Hikvision cctv camera to youtube. We're not
putting text on the image but are using the "-vf curves" command to
eliminate fog. The CPU was unable to do the curves filter at 30fps above
1080p. We put my GeForce 1060 3GB in the computer, and it doesn't use much
CPU at all now. Here is the command we're using that uses the Nvidia GPU.
c:\ffmpeg\bin\ffmpeg1.exe -re -rtsp_transport tcp -y -i "rtsp://
admin:12345@192.168.1.64:554" -f lavfi -f dshow -rtbufsize 2000M
-thread_queue_size 5096 -i audio="virtual-audio-capturer" -c:a libmp3lame
-ab 128k -ar 44100 -bufsize 5096k -c:v h264_nvenc -preset:v hq -rc cbr_hq
-b:v 12M -buffer_size 10000k -vf curves=psfile=c22.acv -f flv "rtmp://
a.rtmp.youtube.com/live2/abcd-efgh-1234-1234"
If you an afford it, a GPU would help a lot.

I have a ip cam ( hikvision) , so far using only stream to youtube

( ffmpeg -re -rtsp_transport tcp -i
rtsp://admin:xxxxx@192.168.2.25:554/Streaming/Channels/1 -tune
zerolatency -vcodec libx264 -pix_fmt + -c:v copy -ac 1 -c:a aac -strict
experimental -f flv rtmp://a.rtmp.youtube.com/live2/x-x-x-x )
working as well,
but now I want drawing text from dynamic text file.
ffmpeg -re -rtsp_transport tcp -i
rtsp://admin:xxxxx@192.168.2.25/Streaming/Channels/1 -acodec aac -ar
8000 -b:a 64k -vcodec libx264 -vf

4 txt files writing per second a program (scoreboard) names, points,
time, line number
both bat files ( I using on win 10) working well, but first code cpu
usage is 4-5 percent, and the second cpu usage is 50% !!!
it is not so good because 4-5 pieces stream send to youtube...
What is te perfect solution that the cpu usage be small.
Thanks!
Robert
