ffmpeg save difference between 2 videos to file
10 août 2020, par 0x-1I'm currently trying to learn everything related to videos and encountered a problem that I need help with.


The Question is : How can I save the difference between 2 videos to a seperate file with ffmpeg ?

For example here is the ffplay command I'm trying with :
(Source : https://superuser.com/questions/854543/how-to-compare-the-difference-between-2-videos-color-in-ffmpeg)

ffplay -f lavfi "movie=left.mp4,setpts=PTS-STARTPTS,split=3[a0][a1][a2];
 movie=right.mp4,setpts=PTS-STARTPTS,split[b0][b1];
 [a0][b0]blend=c0_mode=difference[y];
 [a1]lutyuv=y=val:u=128:v=128[uv];
 [y][uv]mergeplanes=0x001112:yuv420p,pad=2*iw:ih:0:0[down];
 [a2][b1]hstack[up];[up][down]vstack"



In this case I would want to have the bottom left video saved to a new file.

Can someone help me get together the right ffmpeg filter and explain the proccessing of ffmpeg ?

PHP ffmpeg - save mp4 as H.264 in Baseline profile
2 mai 2020, par PikabooI'm trying to play a mp4 file in android but it's not working.



According to Android VideoView Cannot play video mp4



the file needs to be
H.264 in Baseline
.


I don't know what the hell this means.



This is the PHP code I'm using to create mp4 :



$videoname = str_replace('.gif', '.mp4', $picname);
$ffmpeg = FFMpeg\FFMpeg::create(array(
 'ffmpeg.binaries' => 'ffmpeg/bin/ffmpeg.exe',
 'ffprobe.binaries' => 'ffmpeg/bin/ffprobe.exe',
 'timeout' => 6600, // The timeout for the underlying process
 'ffmpeg.threads' => 12, // The number of threads that FFMpeg should use
), $logger);

$video = $ffmpeg->open('memes/' . $folder . '/' . $picname);
$video
 ->save(new \FFMpeg\Format\Video\X264(), 'memes/' . $folder . '/' . $videoname);




How can I set it to be
H.264 in Baseline
profile ?
