To concatenate more than two video using FFMPEG
21 décembre 2018, par Alok Kumar VermaI’ve been working on FFMPEG, this is indeed not an easy task since I’ve succeeded in doing some work. I’m done with concatenating two videos using ffmpeg but somehow when it comes to more than two it does not work. So I’m finding out some command to do my task.
The thing I did is to merge two videos are :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-strict", "experimental", "-filter_complex",
"[0:v]scale=1920x1080,setsar=1:1[v0];[1:v] scale=iw*min(1920/iw\\,1080/ih):ih*min(1920/iw\\,1080/ih), pad=1920:1080:(1920-iw*min(1920/iw\\,1080/ih))/2:(1080-ih*min(1920/iw\\,1080/ih))/2,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=2:v=1:a=1",
"-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "1920x1080", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", savingPath};The above is working fine for two videos. I’ve tried altering my code for three videos but it does not work.
What I’ve done in the above code is :
- Added one more input after the second one
- Changed the concat=3:v=1:a=1
But it does not merge and gave me this error in my LogCat :

After following the LordNeckbeard’s suggestion from the comment section, I’ve used his suggestion in my code but after doing that still no luck however the console’s output got changed and here is the command which I used :
String complexCommand[] = {"-y", "-i", "/mnt/m_external_sd/Videos/VID-20161221-WA0000.mp4", "-i", "/mnt/m_external_sd/Videos/Brodha V - Aathma Raama [Music Video]_HD.mp4", "-i", "/mnt/m_external_sd/DCIM/Sinha's POP/20150530_073113.mp4", "-strict", "experimental", "-filter_complex",

And the logs are :

ffmpeg pipe webcam stream input to two outputs image and video with audio included
23 septembre 2017, par Arianna Gomez VargasI have the next command :
sudo ffmpeg -ar 44100 -ac 2 -f alsa -i hw:1,0 -f v4l2 -codec:v h264 -codec:a aac -ab 128k -framerate 30 -video_size hd720 -itsoffset 0.5 -i /dev/video0 -vf fps=1 snapsh%d.png -f mpeg -b:v 5000k -copyinkf -codec:v copy -codec:a aac -ab 128k -g 10 - | sudo ffmpeg -y -i - out.mp4
and the objetive it is record audio and video simultaneously, and pipe the output to be capable to take screnshots of the output video. I’m using a logitech webcam, raspberry pi 3, the last version of ffmpeg with h264 and alsa support.
But it is not working for me :(, I think that the problem it is enconding the audio stream, but I can find a solution yet.
Someone have any suggest ? ThanksThis is the output
