Mixing audio and video with ffmpeg [closed]
3 septembre 2013, par Narendra DroidWormI am having an mp4 video (without audio), to which I want to add music using ffmpeg, and also want the output video to be of the same length as the input video.
But, as a result, I am getting an video merged with audio, but consuming a little more time (abt 1-2 seconds) in the start with a black screen.
I am using the following command for my desired output.
ffmpeg -i audio.mp3 -i video.avi -acodec copy -vcodec copy output.aviPlease suggest, what modifications should I do to get my desired output.

ffmpeg giving two parameters to vcodec [closed]
20 juin 2013, par Narendra DroidWormBelow is the ffmpeg command to convert still images into video with the delay of 5 seconds to each image.
ffmpeg -f image2 -r 1/5 -i img%03d.png -vcodec libx264 out.mp4This command is working fine. I just wanted to know, whether it is possible to put two parameters for -vcodec, as along with libx264, I also want to use H264, to make that video work even on i-phone.
