Zoltan - the only problem with this, that I just realized is this:
As I mentioned before, the cameras intermittently lose connection.
Supposing that I send the ffmpeg test command while the camera connection is
good, and then the camera stream input to ffplay drops. Ffplay will
continue displayi
Zoltan:
Ok, I tested this and you are correct - it works. Thank you, very much.
I unplugged the camera and ran the ffmpeg command, you suggested and I
promptly received a:
"Connection to tcp://192.168.0.2 failed: Connection refused
http://192.168.0.2: Connection refused"
I can work with this.
Any way to do this in C#? I have resorted to temporarily renaming those
file names/filepaths to English and then renaming back to the original
language once rendering is completed.

Hi all,
I'm trying to embed some ffmpeg filters, such as loudnorm and silenceremove in
a real time context: meaning I have an audio speaker connected at the end of it.
I saw that loudnorm supports single pass mode; where it doesn't require me to
pass all the audio in the file through it, before

I'm using multiple instances of ffplay, on a linux distro, to play multiple

wifi environment I'm in and the 2.4ghz limitations of the cameras, I

Of course not! What I asked was "how does this performance change if you omit

approximately how much of your CPU performan

if -c:v copy then not working drawtext!
only -c:v copy using the cpu usage 2-3% , it is working long ago
but now need use draw text on the video stream
so the drawtext re encoding do high cpu usage, I use the notebook (
