FFmpeg audio dont work in converted videos
- by Juddy Swaft
NOTICE: when i convert videos via terminal and download them from ftp into pc the audio works fine. I use:
if($ext == "avi" && $convert_avi == true)
{
$convert_source = _VIDEOS_DIR_PATH.$new_name;
$conv_name = substr(md5($file['name'].rand(1,888)), 2, 10).".mp4";
$converted_file = _VIDEOS_DIR_PATH.$conv_name;
$ffmpeg_command = 'ffmpeg -i '.$convert_source.' -acodec libmp3lame -vcodec libx264 -s 1280x720 -ar 44100 -async 44100 -r 29.970 -ac 2 -qscale 5 '.$converted_file;
echo exec($ffmpeg_command);
$sql = "UPDATE pm_temp SET url = '".$conv_name."' WHERE url = '".$new_name."' LIMIT 1";
$result = @mysql_query($sql);
unlink($convert_source);
}
This code to convert avi to mp4 ffmpeg concole output:
