To concatenate more than two video using FFMPEG
I'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 :

I've tried one more command which works fine for concatenating two videos but still it does not work for more than two videos :
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",
"[0:v]scale=480x640,setsar=1:1[v0];[1:v]scale=480x640,setsar=1:1[v1];[v0][0:a][v1][1:a] concat=n=3:v=1:a=1",
"-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-q","4","-preset", "ultrafast", savingPath};
You can clearly see in the above code that I've tried using this for the three videos but still no luck. Will appreciate your help. Thanks.
EDITS
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",
"[0:v]scale=480x640,setsar=1[v0];[1:v]scale=480x640,setsar=1[v1];[v0][0:a][v1][1:a] concat=n=3:v=1:a=1",
"-ab", "48000", "-ac", "2", "-ar", "22050", "-s", "480x640", "-vcodec", "libx264","-crf","27","-preset", "ultrafast", savingPath};
Here you can clearly see that I've used setsar=1 and used -crf only.
And the logs are :

You omitted the filterchain for your third input and you did not provide enough inputs to concat. Change the command to:
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", "-filter_complex",

The only additional thing I did was to remove -strict experimental. Only old versions need that. I left everything else the same.
