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

Also My code is simply this:

ffmpeg(fileName)
.videoCodec("libx264")
.audioCodec("libmp3lame")
.outputOptions(`-vf subtitles=${subtitlesPath}`)

I have tried using the sub_charenc option but I wasn't able to get the proper result.
I'm using ffmpeg to convert audio from FLAC to AAC and I'd like to use the aac_mf encoder, which uses Microsoft Media Foundation. If I use the native AAC encoder built into ffmpeg it works with the following command:
ffmpeg -i input.flac -acodec aac -vn output.m4a
However, the following command gives an error:
> ffmpeg -i input.flac -acodec aac_mf -vn output.m4a

This is a bug. For now, add -frame_size. Will be fixed in 5.1 and soon in git master.

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 am using fluent ffmpeg with ffmpeg v4.1.3 for HLS mukti bitrate streaming but I m not able to use -var_stream_map config it says option, not found but running this command outside fluent-ffmpeg works fine
Here is my code
const stream = ffmpeg(filePath);
stream.outputOptions([
'-preset slow',
'-g 48',
'-map 0:0',
'-q:a:0 64k',
'-q:a:1 128k',
'-var_stream_map a:0 a:1',
'-hls_time 6',
'-f hls',
'-hls_list_size 0',
'-master_pl_name /tmp/master.m3u8',
"-hls_segment_filename /tmp/v%v/fileSequence%d.t",
"/tmp/v%v/prog_index.m3u8"
])
.output('./master.m3u8')
.on('progress', function(progress) {
console.log('Processing: ' + progress.percent + '% done')
})
Here is the output

Unrecognized option 'var_stream_map a:0 a:1'.
Error splitting the argument list: Option not found
Can someone tell me how can I pass it correctly?
I also face the same problem and solve that by putting the 'var_stream_map' in another outputOption().
stream.outputOptions([
'-preset slow',
'-g 48',
'-map 0:v', '-map 0:v',
'-map 0:a', '-map 0:a',
'-q:a:0 64k',
'-q:a:1 128k',
'-hls_time 6',
'-f hls',
'-hls_list_size 0',
'-master_pl_name /tmp/master.m3u8',
"-hls_segment_filename /tmp/v%v/fileSequence%d.t",
"/tmp/v%v/prog_index.m3u8"
])
.outputOption('-var_stream_map', 'v:0,a:0 v:1,a:1')
.output('./master.m3u8')
.on('progress', function(progress) {
console.log('Processing: ' + progress.percent + '% done')
})
On command line it is recommended put the var_stream_map value between quotation marks.
'-var_stream_map', '"a:0 a:1"'
Also the -map parameter adds only one stream (stream 0:0). If you want to have two audio streams you must also add the -map parameter two times:
-map 0:0 -map 0:0
Here the same input stream 0:0 is added two times for the output processing.
I need to get stdout of rtsp stream without formatting. May someone know how to do it?
This is what I get if try to ffmpeg manually from command line:

NodeJS code sample
this.stream = child_process.spawn("ffmpeg", ["-rtsp_transport", "tcp", "-i", this.url, '-acodec', 'copy', '-vcodec', 'copy', '-'], {
detached: false
});
this.inputStreamStarted = true;
this.stream.stdout.on('data', function(data) {
return self.emit('mpeg1data', data);
});
this.stream.stderr.on('data', function(data) {
return self.emit('ffmpegError', data);
});
When outputting a pipe you are required to manually instruct ffmpeg what output format you want to use. You can do this with the -f option. Example:
ffmpeg -rtsp_transport tcp -i rtsp://admin:pass#10.168.9.141/Streaming/channels/1/ -c copy -f mpegts -
This does not perform any re-encoding because -c copy is being used.
