Use subprocess.
proc = subprocess.Popen("ffmpeg", "next arg", "next arg")
Remember to import subprocess.

I want to generate multiple qualities (Representations) for HLS stream while capturing from webcam. I am using ffmpeg. I want to take video from camera, scale it and generate .m3u8 playlist that contains three qualities.
This is what I have tried:
ffmpeg \
-input_format yuyv422 \
-f v4l2 -video_size 640x480 \
-i /dev/video0 \
-c:v libx264 -crf 21 -preset veryfast \
-b:v 100M -b:a 128k \
"[0:v]split=3[v1][v2][v3]; \
[v1]copy[v1out]; [v2]scale=w=1280:h=720[v2out]; [v3]scale=w=854:h=480[v3out]" \
-map [v1out] -c:v:0 libx264 -x264-params "nal-hrd=cbr:force-cfr=1" -b:v:0 5M -maxrate:v:0 5M -minrate:v:0 5M -bufsize:v:0 10M -preset slow -g 48 -sc_threshold 0 -keyint_min 48 \
-map [v2out] -c:v:1 libx264 -x264-params "nal-hrd=cbr:force-cfr=1" -b:v:1 3M -maxrate:v:1 3M -minrate:v:1 3M -bufsize:v:1 3M -preset slow -g 48 -sc_threshold 0 -keyint_min 48 \
-map [v3out] -c:v:2 libx264 -x264-params "nal-hrd=cbr:force-cfr=1" -b:v:2 1+3M -maxrate:v:2 3M -minrate:v:2 3M -bufsize:v:2 3M -preset slow -g 48 -sc_threshold 0 -keyint_min 48 \

-hls_segment_filename stream_%v/data%02d.ts \
-master_pl_name master.m3u8 \
-var_stream_map "v:0,v:1,v:2" stream_%v.m3u8
As a result, I get only one quality in the playlist and that is the last one in order (854 x 480).
my code:
sudo ffmpeg -i rtsp://rtsp.stream/pattern \
-map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 -map 0:v:0 -map 0:a:0 \

-hls_time 3 -hls_flags independent_segments \
-master_pl_name "livestream.m3u8" \
-y -vsync 0 -hwaccel cuda "/var/www/livestream-%v.m3u8"
Option hwaccel (use HW accelerated decoding) cannot be applied to output url /var/www/livestream-%v.m3u8 -- you are trying to apply an input option to an output file or vice versa. Move this option before the file it belongs to.
Error parsing options for output file /var/www/livestream-%v.m3u8.
It doesn't work with the above error.

-hls_time 3 -hls_flags independent_segments \
-master_pl_name "livestream.m3u8" \
-y "/var/www/livestream-%v.m3u8"
The above operates as a cpu and annoys my cpu. I don't know how to write the command.=
Any ideas?
I'm trying to produce an HLS playlist from a video file.
It's a file captured from a virtual screen with ffmpeg and x11grab module:
ffmpeg -y -t 10 -copyts -draw_mouse 0 -framerate 24 -f x11grab -thread_queue_size 1024 -i :0 -f pulse -i default -acodec copy /tmp/test_preprocessed.mkv
But when I'm trying to produce HLS from this file, the output seems not correct, as it doesn't play in Firefox/Safari, but does play in Chrome (using hls.js or https://www.hlsplayer.net/ for example)
Original file: https://transfer.sh/y1a6Fv/735171b9-42a1-461a-a118-981119bdf74e_preprocessed.mkv
HLS Playlist generated from this file: https://video-staging-bucket.ams3.digitaloceanspaces.com/c08584ca-4731-4820-b5c7-71f12955c0b2/stackoverflow/playlist.m3u8
(Works in https://www.hlsplayer.net/ with chrome, doesn't works with Firefox/Safari)
How I'm producing the HLS:
ffmpeg -y \

Is there something I missed ? Maybe a standard ? Or maybe problem is related to PTS/DTS of my file ?
Thanks !
There is a command that generates hls videos in different sizes.
Now I need to merge them into one master playlist. (What is a master playlist) How do I do this? What and where do I need to add in this command?

What I am interested in is the automatic creation of a master playlist using ffmpeg in this command.

After several attempts, I still got the desired result. I modified the command and now it looks like this

I have this ffmpeg command in order to create an HLS video with four versions with different quality features, but I don't manage it creates the .m3u8 playlist. I have added at the end of the command the control -master_pl_name, but it doesn't work.
Can someone help me to create the command I want?

-master_pl_name "MyNewVideo_index.m3u8"
I'm working on a similar problem and am equally surprised by the seeming lack of resources about this.
Anyway, I think you'll be able to get a step further if you add a single output file name after -master_pl_name "MyNewVideo_index.m3u8" output_%v.m3u8. I would then recommend removing the individual names for the quality streams, otherwise FFmpeg will create them twice.
It's possible you'll then have other issues, as I am, but that should solve your first problem.
