How to merge videos and add audio in a single command using ffmpeg ?
9 janvier 2017, par harishkumar329I use the following commands to concat audio-less video files to one and add audio to it,
To concat individual videos,
ffmpeg -i 1.mp4 -i 2.mp4 -i 3.mp4 -i 4.mp4 -i 5.mp4 -filter_complex 'concat=n=5:v=1:a=0[out]' -map '[out]' -strict -2 -y video_withoutaudio.mp4
To add audio,
ffmpeg -i video_withoutaudio.mp4 -i audio.mp4 -c:v copy -c:a aac -strict -2 video_withaudio.mp4
is there a way to combine these two commands to one ?
My requirement is to optimise the commands as I have 1000+ commands taking a lot of time to complete, hoping combining these two to one will save some time.
Thanks in advance !

I need to take a live video stream from wowza and convert it to a JPEG Push for display in HTML5
10 septembre 2015, par scott m gardnerI have a live video feed that currently is served by a Wowza server as an RMTP stream. I need to create an Motion JPEG, or JPEG push stream to HTML5. I have FFMpeg, and have used it to generate individual frames from a video file, but do not know how to put it all together. Or how to package the frames together for transmission to the client.
I am guessing that I will have to do some coding on the server side to package everything up. I will do this in Java or Scala. And on the client to handle the un packaging and display to the canvas in JavaScript.
