PHP Run FFMPEG in background, and find out when it's done [closed]
27 septembre 2012, par toms900Possible Duplicate :
Run a ffmpeg process in the backgroundI was wondering if there's any easy way to runn and ffmpeg process in the background so people can leave the page. And if you do that, then tell if the ffmpeg process is running, and when it's done, update the database to "finished". I'll post my code if I need to. Thanks !

Bad quality output with FFmpeg, bitrate specified [closed]
28 septembre 2012, par Darkman2412I have a static background image where I add 2 videos on top of it using FFmpeg CLI. The output file (
test.aviin this case), is very bad quality.ffmpeg -loop 1 -i outro.png
-vf "movie='intro.mov' [last], [last]scale=512:288[scaled1], [in][scaled1] overlay=290:396 [tmp];
movie='intro2.mov' [featured], [featured]scale=512:288[scaled2], [tmp][scaled2] overlay=1118:396 [out]" -b 512k -t 10 -r 30 -y test.aviThe first image is the first frame of
test.avi.
The second one is what it should be.
Edit : my question is why it's such bad quality.
Edit2 : Console output :
