FFMPEG 1080p50 to 1080p25 bad channel logo [on hold]
16 mars 2018, par SambirI try to run ffmpeg and gpu encoding. The input stream is 1080p50 (which is 1080i50 to 1080p25 and then to p50 again). I want to transcode this @ 1080p25 but the output is not really smooth. The corners of the channel logo are not smooth and when small letters goes across the screen they are not smooth aswell.
But when transcode @ 1080p50 then all is fine. But you can see the logo shaking. Its like running @ 720p50.
Is there a way i can make the logo look smooth @ 1080p25 ? I tried using vf yadif and it helped a bit but the logo is a bit blurry now.
With gpu deinterlacing it’s worse.
This is my current command line
ffmpeg.exe -vcodec h264_cuvid -i rtmp://192.168.2.3:8001/input/channel -map 0:0 -map 0:1 -vf yadif=1 -acodec libfdk_aac -b:a 96k -c:v h264_nvenc -gpu 0 -preset llhq -vprofile high -rc:v vbr -qmin:v 26 -qmax:v 32 -b:v 4M -maxrate 4M -bufsize 8M -threads 0 -r 25 -g 100 -f flv rtmp://192.168.2.3:8001/input/test10.stream -

27 mars 2022, par Medicare AdvisorsWe are converting videos to MP4 using FFMPEG.


We did a lot of research, however we cannot figure out how to add the company logo as a logo or a water mark to the converted video


PHP code


<?php 
$uploads_dir = 'original/';
$file_name = basename($_FILES['file']['name']);
$output_name = explode('.', $file_name)[0];
$uploaded_file = $uploads_dir . $file_name;
$convert_status = ['mp4' => 0, 'webm' => 0];

if(isset($_POST['submit'])) {
 if(move_uploaded_file($_FILES['file']['tmp_name'], $uploaded_file)) {
 // Make sure to get the correct path to ffmpeg
 // Run $ where ffmpeg to get the path
 $ffmpeg = '/bin/ffmpeg';
 
 // MP4
 $video_mp4 = $output_name . '.mp4';
 exec($ffmpeg . ' -i "' . $uploaded_file . '" -vcodec h264 -acodec libfdk_aac "./converted/' . $video_mp4 . '" -y 1>convert.txt 2>&1', $output, $convert_status['mp4']);

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';

 

 // Debug
 // echo '<pre>' . print_r($output, 1) . ' </pre>';
 }
}
?>
