[FFmpeg-user] Info

Hi, 

I'm trying to run a stream on YouTube a video that loops 24/7, using FFmpeg 4.4 from a server with Ubuntu 22, but cannot succeed, any help would be appreciated.

Here's 2 scripts I made, the 1st one works with a CPU showing around 75% but does not loop.

VBR="1500k"
FPS="24"
QUAL="superfast"

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"
KEY="mykey"
SOURCE="/home/ubuntu/Video.mp4"
AUDIO_SOURCE="/home/ubuntu/Music.mp3"
ffmpeg \
    -re -f lavfi -i "movie=filename=$SOURCE:loop=0, setpts=N/(FRAME_RATE*TB)" \
    -thread_queue_size 512 -i "$AUDIO_SOURCE" \
    -map 0:v:0 -map 1:a:0 \
    -map_metadata:g 1:g \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 6 -qscale:v 3 -b:a 320000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"


The 2nd script loops but the CPU on the server shows 190% and I loose the "Live" red light on YouTube.


VBR="1500k"                                    
FPS="24"                                      
QUAL="superfast"                                 

YOUTUBE_URL="rtmp://a.rtmp.youtube.com/live2"  
SOURCE="/home/ubuntu/Video.mp4"              
KEY="mykey"                  
ffmpeg \
    -stream_loop -1 -i "$SOURCE" -deinterlace \
    -vcodec libx264 -pix_fmt yuv420p -preset $QUAL -r $FPS -g $(($FPS * 2)) -b:v $VBR \
    -acodec libmp3lame -ar 44100 -threads 6 -qscale 3 -b:a 712000 -bufsize 512k \
    -f flv "$YOUTUBE_URL/$KEY"

Thanks.
