The attachment in your first reply went through fine, I can see it. But it is
too simple, I mean I can remove silence in it pretty well with
% ffplay Downloads/sample.wav -af
"silenceremove=start_periods=1:start_threshold=-30dB"
But I assume you’re having more trouble with the original file beca

Hello,
Persisting connections is the default and the same is true for multiple
connections if the server supports it. Have you ruled out your http server
config as the cause?
Also does this matter for localhost, or is that just a placeholder for examples?

Hello,
I am novice to programming upon ffmpeg. I would like to know how ffmpeg

Could you point me to the files/functions that do this job?

Dear ffmpeg community.
I want to perform a repackaging from .m4s (DASH segments) to .ts (HLS
segments). Is that possible to do with FFmpeg? How can I proceed?
Thank you very much for your help.
Kind regards.

Hi,
Enabling http_persistent and encryption in the hls muxer leads to HTTP
connections that multiple Web servers cannot deal with properly.
In particular, ffmpeg sends HTTP PUT requests with a "Connection: keep-alive"
header for each segment file, but it closes the connection right
afterwards and

How do you figure results are correct?
ffmpeg -i '/home/tony/test/Recording_53.wav' -af silenceremove=1:0:-20dB
recording53_silences_removed.wav
this one does'nt remove anything.

How are you supposed to differ from faint ones and noise itself.

Hello, Thanks so much for your reply.
Would the microphone pickup just as much sounds (even faint ones)
if i set gain back to 1.0x?
If audio was in any way processed prior to silence removal, like in
this case with gain, you will certainly get poor results.

Hello, and thanks so much for your reply.
I was actually only requesting help for the silenceremove arguments (or
settings or
however they're called) on the commandline.
The -20 dB threshold will not be my final settings. It was just to make sure
something is removed.
I don't know if you only r

Hi,
MS Surface Pro 7 rear camera does not activate when trying to capture stream.
This is the command I am using :
