In this configuration file
https://github.com/TareqAlqutami/rtmp-hls-server/blob/master/conf/nginx.conf#L24-L30
for each received stream, transcode for adaptive streaming This single
ffmpeg command takes the input and transforms the source into 4
different streams with different bitrates and qualities. # these
settings respect the aspect ratio.
How we can dynamically generate variants? i.e for 1080p input generate all variants, but for 240p input generate no variants
My startup works without error
You need to configure the log and see what error it gives.
But another solution is to check manually
You may be using a codec that is not installed
I will check your tank, maybe I can contribute here

I can't figure out why exec_record_done isn't being called here. on_record_done gets called but not the exec_. I've checked the script files and perms are all ok. There's nothing in the nginx logs about exec_record_done... Any ideas or suggestions to debug further?

I can use this code in my nginx server. this is code running but dont run while write libx264 instead libx265.
The interesting thing is that I can run the following commands on my linux computer without problems.
ffmpeg -i input.mp4 -c:v libx264 -crf 28 -c:a aac -b:a 128k output.mp4
ffmpeg -i input.mp4 -c:v libx265 -crf 28 -c:a aac -b:a 128k output.mp4

Hello i am transcoding video with rtmp and i want to put some text...i put Arial.ttf in my home directory of the server but doesnt work.. this is my command..
-map 0:0 -map 0:1 -strict -2 -crf 26 -vcodec libx264 -preset superfast
-acodec aac -b:a 128k -vf scale=-1:720 -aspect 16:9 -g 50 -r 30 -ar 48000
-ac 2 -vf drawtext="fontfile=/home/Arial.ttf: text='TEXT': fontcolor=white: fontsize=24: box=1: boxcolor=black: x=10:y=10"
-f flv
can someone help me please?
thanks
Make sure you include absolute path to font and file is there:
drawtext="fontfile=/usr/share/fonts/truetype/freefont/FreeSerif.ttf:
text='Test Text': x=100: y=50: fontsize=24: fontcolor=yellow#0.2:
box=1: boxcolor=red#0.2"
Redirect output to a log file and see if command outputs any errors.
You can also include a watermark image instead:
-i /path/to/watermark.png -filter_complex "overlay=main_w-overlay_w-4:4"
Right now I am saving all the files and folders created by hls in a single directory like this
application live {
live on; # Allows live input
# Once receive stream, transcode for adaptive streaming
# This single ffmpeg command takes the input and transforms
# the source into 4 different streams with different bitrate
# and quality. P.S. The scaling done here respects the aspect
# ratio of the input.

How do I make a new directory for every hls streams according to the name of streams.
I want stream to rtmp server. I try:
ffmpeg.exe -f dshow -i "myvideo.avi" -s 480x288 -r 10 -vcodec libx264 -b:v 30k -pix_fmt yuv420p -acodec libvo_aacenc -ac 1 -b:a 4k -f flv rtmp://ip/live/test
And did not work... Error:

how to do? Thx
