Lower video quality with ffmpeg?
I have a video in heigh quality I would like to play on my netbook, but it's chopy. I'm thinking my netbook doesn't have to power to play it. How can I lower the quality so my netbook will play it?
Code:
>ffmpeg -i Avata.mp4 |
Not sure exactly the proper syntax but maybe something like:
Code:
ffmpeg -i /path/to/avatar.mp4 -s 1366x768 /location/for/converted/avatar.mpg I'm not at my linux machine so unable to test it but this should get you going. Check the man page for detailed info. Code:
man ffmpeg Another app choice is 'avplay' Keep us posted, good luck! |
I've been using vlc and totem. The command you gave me is not working.
Code:
ffmpeg -i Avatar.mp4 -s 1366x768 Avatar-lower.mpg <-- ~/Media |
Lower the quality means?
Do you want to reduce the resolution or reduce the size? Try this Code:
ffmpeg -i "Avatar.mp4" -f mp4 -vcodec mpeg4 -b 512k -r 30 -s 640x360 -acodec libfaac -ar 32000 -ab 128k -ac 2 -threads 8 "Avatar_out.mp4" -s = resolution of the video, 640x360 is common resolution for mobiles. but it should be according to aspect ratio. If you put it here anything, it gives error. |
My first recommendation is to try the multi-threaded decoding in mplayer:
Code:
mplayer -vo xv -af volnorm=1 -subfont-autoscale 1 -lavdopts threads=4 -idx movie.mp4 Code:
ffmpeg -i input.mkv -vcodec libx264 -vpre special -crf 15 -s 640x288 -aspect 16:9 -r 23.976 -threads 4 -acodec libvo_aacenc -ab 128k -ar 48000 -async 48000 -ac 2 -scodec copy output.mkv Code:
