FFMPEG - Watermark video with same quality and filesize
29 mars 2012, par ddlshackI have some videos, and I'd like to watermark them with a transparent PNG. Here's what I've tried :
ffmpeg -i 9.flv -vf "movie=logo.png [watermark];[in][watermark] overlay=10:10 [out]" 9_w.flv
However, bitrate or quality is not preserved. Preferably I'd like ffmpeg to re-encode the file with exactly the same settings as the original file (same codecs, bitrate). If thats not easily possible, I'd like to encode with a specific codec, but preserving 'quality', however that is measured.

ffmpeg video encoding for mobile devices
27 janvier 2012, par TimGLI'm trying to encode the video file from f4v to mp4 for mobile devices and using 2 different ffmpeg versions with the same configuration files. Encoding goes ok for both files. The one that I convert using ffmpeg version N-32754-g936d4d4-Sherpya failing to play on my blackberry.
This is the command line that I'm using :ffmpeg.exe -i some.avs -vcodec libx264 -b 500k -r 24 -acodec libfaac -ab 128k -ar 48000 -ac 2 -threads 0 -coder 0 -bf 0 -refs 1 -level 30 -maxrate 10000000 -bufsize 10000000 -y test.mp4
The vido playes ok when I convert it using FFmpeg version SVN-r13712
Could you give me some light on where the issue couls be ? -
Linux Platform : Enlarge video screen size N times
27 janvier 2012, par Susan MayerI am looking for a application on Linux platforms (Ubuntu/CentOS etc) that can enlarge video size N times. N could be any number, like 1.5, 4 etc
For example, if I have a video with screen size 100*200, I want to make it 1.5 times larger, that will be : 150*300. Of course, I will expect the video quality to drop but it doesnt matter.
I am not sure whether ffmpeg has this function but a quick Google lands me nowhere. So I am here now.
Thanks a lot !
