I'm using Jmeter 3.2 without any special plugins.
I just installed Inter-Thread Communication plugin.
I download the example jmx in plugin page and when I open it I get pop up with the below exception:
I didn't find an issue about it also in jmeter-plugins.

It worked only after I installed HTTP Raw request plugin

I want to concatenate some mp4 videos but coundn't manage to solve the audio problems.
Here are sample videos, to be concatenated, in this order: 1, 2 and 3. A concat.txtis also supplied. 2.mp4 is a fragment of a larger video and was reencoded (not just cut).
None of my attempts worked. Most of them lead to gaps in the audio, some change the pitch of the voice. There's clearly a DTS issue I just don't know how to deal with.
Sometimes there are more than three videos to put together.
What I tried so far:
The most obvious: fmpeg -f concat -safe 0 -i concat.txt -c copy out.mp4. This complains a lot (non-monotonous DTS). Very poor result.
Re-encoding video and audio: ffmpeg -f concat -safe 0 -i concat.txt -c:v libx264 -c:a aac out.mp4. Same poor result in a time consuming task. Using copy to avoid re-encoding just audio or just video leads nowhere.
Running away from mp4: I converted all files to avi and to ts thinking that that could be an mp4 issue. Bad results with avi and slightly better results with ts. Nothing good, though.
I tried playing with -video_track_timescale. No success.
I actually don't care about re-encoding the video, since the original has not a great quality already. But the audio issue must be solved.
I also hope for a generic solution, since I have many videos to handle and I wish to use just a script. Adjusting parameters for every single case would be a burden.
Using ffmpeg version 4.3.3 and Debian 11.

I want to concatenate some MP3 files using the FFmpeg concatenation protocol.
Here is a successful try:
$ ffmpeg -loglevel panic -i "concat:audio/it/ci.mp3|audio/it/èsse.mp3|audio/it/cu.mp3|audio/it/u.mp3|audio/it/tre.mp3|audio/it/zero.mp3|audio/it/cinque.mp3|audio/it/quattro.mp3|audio/it/tre.mp3|audio/it/otto.mp3|audio/it/tre.mp3" -c copy audio/it/CSQU3054383.mp3 -y
$ ll audio/it/CSQU3054383.mp3
-rw-rw-r-- 1 giorgio 26K Nov 9 16:16 audio/it/CSQU3054383.mp3
So far, all is OK!
BTW, all (Mp3) files have the same codecs, so MP3 FFmpeg concatenation protocol runs as expected!
Now, I want to insert a pause file audio/it/PAUSE_2.mp3, between each previous files:
$ ffmpeg -loglevel panic -i "concat:audio/it/ci.mp3|audio/it/PAUSE_2.mp3|audio/it/èsse.mp3|audio/it/PAUSE_2.mp3|audio/it/cu.mp3|audio/it/PAUSE_2.mp3|audio/it/u.mp3|audio/it/PAUSE_2.mp3|audio/it/tre.mp3|audio/it/PAUSE_2.mp3|audio/it/zero.mp3|audio/it/PAUSE_2.mp3|audio/it/cinque.mp3|audio/it/PAUSE_2.mp3|audio/it/quattro.mp3|audio/it/PAUSE_2.mp3|audio/it/tre.mp3|audio/it/PAUSE_2.mp3|audio/it/otto.mp3|audio/it/PAUSE_2.mp3|audio/it/tre.mp3" -c copy audio/it/CSQU3054383.mp3 -y
$
This command run apparently without any error, but the output file (audio/it/CSQU3054383.mp3) is not generated at all.
**Question 1 (minor):
Why doesn't FFmpeg report any error and doesn't generate the expected output?**
In fact, I already experienced that FFmpeg, in some circumstances, fails without saying why :(
I suspect the problem happens because the file audio/it/PAUSE_2.mp3 doesn't have a constant bit rate (CBR), as other files, e.g.:
$ mediainfo audio/it/ci.mp3

Instead, the inserted pause file has a variable bit rate, as mediainfo states:

Here my Bash script I used to generate the pause:
$ cat com/pause
#!/bin/bash
# https://ffmpeg.org/ffmpeg-filters.html#toc-anullsrc
# https://ffmpeg.org/ffmpeg-utils.html#toc-Examples-1
if [ $# -eq 0 ]
then

echo "example: $0 2"
echo "example: $0 0.5 tmp/"
echo
exit
fi
timeDuration=$1

Unfortunately, the created file seems with a variable bit rate and not with a constant bit rate (CBR), as expected ( -b:a ... ):

Question 2:
What's wrong in my Bash script (why doesn't it generate a CBR file?
How can I generate an silence pause file (silence of N milliseconds) with the exact settings of previous files?
I've recently update vim on ubuntu, and since then, a strange character keep appearing at random time at my cursor place. It seems to appear when I do nothing for some seconds. The character is >4;2m and I can't understand the logic of its appearance. Has anyone the same problem ? Switching buffer and coming back to the initial one clean the character.

It was a problem of modifyOtherKeys. After looking at the doc, putting
let &t_TI = ""
let &t_TE = ""
in my vimrc solved the problem.
This works for me:
touch ~/.vimrc
i'm trying to stream two webcam in sbs mode using ffmpeg websocket.
It works but there is a delay of some second between the two scene.
Here is what I do :
ffmpeg -f v4l2 -framerate 30 -video_size 1280x720 -input_format mjpeg
-i /dev/video1 -f v4l2 -framerate 30 -input_format mjpeg
-video_size 1280x720 -i /dev/video0 -filter_complex "

In Linux ffmpeg returns the error in red:

How can I fix this problem?
Use
/usr/bin/ffmpeg -i video.mp4 -vstats -map 0:v -f null - 2>&1
Or you could just use ffprobe
ffprobe -show_entries format=duration -of compact=p=0:nk=1 video.mp4
