[video4linux2,v4l2 @ 0x643732e80b40] The driver changed the time per frame from 1/18 to 1/30


Is there any problem in my encoder client code ?


In addition, i can't send datas to server.

FFmpeg : convert .mpg video to .mp4 without losing quality
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 :

But in
phpinfoandphp -mffmpeg not listed ! yet so I noticed should configure ffmpeg on php then I run :

./configure && make


on
/usr/ffmpeg/ffmpeg-php-0.6.0

But result is :




checking for ffmpeg headers... configure : error : ffmpeg headers not
found. Make sure ffmpeg is compiled as shared libraries using the
—enable-shared option




Then I run :


./configure --enable-shared


But still the same error.


In laravel project I got error :

After many hours searching and testing still I couldn't fix this issue, any suggestion ?
