20 novembre 2024, par reteriusHow can I convert a .mpg video to .mp4 without losing quality ? My attempts below :


$INCPATH = dirname(__FILE__).'/';

$id = 99999;
$ext = "MPG";

$input_dir = $INCPATH."../img/videos/".$id.".".$ext ;
$output_dir2 = $INCPATH."../img/videos/".$id.".mp4" ;

$q = '/usr/bin/ffmpeg -i '.$input_dir.' -c:v libx264 -c:a libfaac -r 30 '.$output_dir2." 2>&1" ;

$out = shell_exec($q) ;
$input_dir = $output_dir2 ;

echo var_dump($out);



Output of running that script :

Prevent output in error log when ffmpeg job is initiated via PHP's shell_exec()
19 janvier 2016, par JakeI’m getting the entire output of the ffmpeg command printed to my server’s error.log — but as far as I can tell, the jobs complete successfully with no error.
Is there any way to suppress the output ? I have seen people append stuff like
>/dev/null 2>/dev/null &
to their command, however that forces the command to return immediately and the job runs in the background. Unfortunately, I need the job to run in the foreground, because I need to do stuff with the output once the job is done.Here’s the command I am running...
shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');
Here’s the output I am seeing...

FFMPEG parameter -sseof position is not “cutting” as expected
9 mai 2020, par VitaliiI have a regular recording of the desktop screen, indefinite in time. I want to keep in memory, only the last 30 seconds. My command looks like this, where I try to cut the video of the last 30 seconds, using
-sizeof -30
. But the entire length of the video is saved.

avfoundation -i '1'
it's my macbook screen


ffmpeg -rtbufsize 300M -sseof -30 -f avfoundation -i '1' -c:v libx264 -preset ultrafast -tune zerolatency -crf 25 ~/Desktop/output.mkv
