I am sorry for the late reply, i found another way of doing the same.
the command i was using in concat script was
ffmpeg -y -re -safe 0 -report -loglevel warning -i "${concat_pls:?}" -codec
copy -b 4000k -minrate 4000k -maxrate 4000k -bufsize 1835k -copyts -strict
-2 -mpegts_service_id $PID -f
I use an old OLD windows program called scanrec19 on my pc laptop and it
works perfectly. That means I need to run my laptop 24/7/365. I'd like to
run everything on my low power consuming Raspberry Pi.
I am a ham radio operator and I am audio logging use of a weather repeater
system in Tennessee
That looks promising, however is there any way to either control the Interval
at which packets are output or any way to get the timestamp of each packet?

You would have to write an application or at least a script
but I would hope that other possibilities exits (I don't know
of any).

I'll start this thread with a simple question. Total Newbie here. My son
will help me configure if I get the answer I want to hear.
I already have ffmpeg installed on Raspberry PI and use it to stream to
Icecast. Works great.
Here is my question:
With ffmpeg can I capture audio from device line

I do not think that overlay can accept three inputs.
When you have that kind of error, re-read your filter graph very very
carefully. Make a diagram on a blackboard of a piece of paper if need
be.
Hi,
I'm making a video from two videos of different lengths. i want to trim
video which will be large in length and should be the same size of both
videos before removing chorma color(Alpha color) from one video.
i'm using following filter:
-y -i (videoPath1) -i (videoPath2) -filter_complex
I'll be creating DASH segments initially with a segment duration (say 1
second), then for my use case I have to change the segment duration of the
DASH segments on the fly (2 or 3 seconds).
I am currently specifying the segment duration using *-seg_duration*
command.
That's why I am eager to

This is not yet possible (and not easy to understand
how you expect this to use).

Is there any way to modify FFMPEG, to change the segment duration on the
fly in the dash encoder .
I want to this from command line.
Or is there any API to do this or any java wrapper to change the segment
duration on the fly?

That's working perfectly.
Now, I need to know which parallelization scheme (slice, tile, or wavefront
parallel processing) is used to encode a video sequence.
How's that possible with *ffprobe*?
