FFMPEG : Change Video during encoding (using mapping)
18 octobre 2013, par TchoupiI'm currently trying to concat several videos using a complex filter :
ffmpeg.exe -threads 8 -i "D:\Temporary0.mp4" -i "D:\Temporary1.mp4" -i "D:\Temporary2.mp4" -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] " -map "[v]" -map "[a]" -vcodec libx264 -b 2500000 -s 1920:1080 -y D:\EditedVideo.mp4
This command work fine.

[libvo_aacenc @ 0420e900] 1 frames left in the queue on closingI would like to update this command to change volume during concat and encode time :
ffmpeg.exe -threads 8 -i "D:\Temporary0.mp4" -i "D:\Temporary1.mp4" -i "D:\Temporary2.mp4" -filter_complex "[0:v] [0:a] [1:v] [1:a] [2:v] [2:a] concat=n=3:v=1:a=1 [v] [a] " -map "[v]" -map "[a]" -vcodec libx264 -b 2500000 -s 1920:1080 -af volume="volume=20dB:precision=double" -y D:\EditedVideo.mp4
This command is executed but the audio stream is not altered with the +20db
PS : If I do a simple encoding command like
ffmpeg.exe -i source -vcodec libx264 -af volume="volume=20dB:precision=double" -y output
Command work fine and audio stream is modified.
So How can I Do to concat my videos and change audio volume at the same time ?
Thanks

ffmpeg - over 1000 files into a mp4
20 octobre 2013, par FabrizioI am using FreeBSD and ffmpeg and I am trying to convert over 1000 files into an mp4. Keep in mind that I am completely NEW to ffmpeg and that in the future I might have up to 3600 images.
I was thinking that simply executing :
ffmpeg -i /usr/local/www/tmp/phpFa5LT3/*.jpg -r 2 output.mp4
would work, but I keep getting

ffmpeg unable to find encoder 'libvorbis'
15 juillet 2014, par scientifficI’m unable to transcode a video file to webm because my machine isn’t able to find libvorbis. When I run the following command :
ffmpeg -y -i /public/uploads/tmp/1382112521-11953-7661/webm_Untitled.mov -vcodec libvpx -acodec libvorbis -s 640x360 -b 1500k -ab 160000 -f webm -g 30 -aspect 1.7777777777777777 /public/uploads/tmp/1382112521-11953-7661/tmpfile.webm
I get the error
Unknown encoder 'libvorbis'
I already have libvorbis installed on my machine, though (When I try "brew install libvorbis, it tells me : Warning : libvorbis-1.3.3 already installed).
How can I solve this problem ?
Here is the full log :
