ffmpeg 在 php exec() 中不起作用

Question

FFMPEG is not working in exec but its working when using ssh on that us but other commands work with exec !

Here is the code :

exec("ffmpeg -i /home/setare/public_html/kanalmanager/wt/230307754.mp4 -i /home/setare/public_html/kanalmanager/wt/230307754_logo.png \
 -filter_complex  "[1]colorchannelmixer=aa=1,scale=iw*1.4:-1[wm];[0][wm]overlay=x=(W-w)/2:y=(H-h)/2" /home/setare/public_html/kanalmanager/wt/230307754_send.mp4 -y");

Answer 1

As Charlotte Dunois said you have syntax error, and this one should works:

exec("ffmpeg -i /home/setare/public_html/kanalmanager/wt/230307754.mp4 -i /home/setare/public_html/kanalmanager/wt/230307754_logo.png \
 -filter_complex  \"[1]colorchannelmixer=aa=1,scale=iw*1.4:-1[wm];[0][wm]overlay=x=(W-w)/2:y=(H-h)/2\" /home/setare/public_html/kanalmanager/wt/230307754_send.mp4 -y");
