• Is there any possibility to transcode a h264 hls/m3u8 live stream into another HEVC (h265) hls/m3u8 live stream using FFmpeg in real time ?

  2 septembre 2024, par Ghenadie Pripa

  The command I used :

  


  ffmpeg -i  https://tezaurtv.md/wp-content/uploads/live/index.m3u8 -c:v libx265 -b:v 1500k -tag:v hvc1 -c:a aac -b:a 128k -f hls -hls_time 10 -hls_list_size 10 -hls_flags delete_segments+append_list+program_date_time -hls_playlist_type event -hls_segment_type mpegts -hls_segment_filename "D:/BRUT/HLS/test/stream_%d.ts" -vsync 2 -rtbufsize 500M -loglevel debug D:/BRUT/HLS/test/stream.m3u8


  


  I tried a lot of commands and parameters but nothing helps. The experiment is on local Windows. Transcode with ffmpeg and play with FFplay.

  


  The problem is the following : After I start stream.m3u8 to play after a few seconds the picture and sound stops. What is wrong in the FFmpeg command ?

• Facing issues with adding text over a video as watermark using ffmpeg in Laravel

  18 septembre 2024, par Kelash

  I am facing issues with adding text over a video as a watermark using pbmedia/laravel-ffmpeg.

  


  Where am I going wrong ?

  


  Code :

  


  $format = new X264();
$format->setAudioCodec('aac');
$format->setVideoCodec('libx264');
$format->setKiloBitrate(0);

$localPath = '/' . $this->video->id . '.mp4';

$ffmpeg = FFMpeg::fromDisk("public")
          ->open($localPath)
          ->addFilter(function ($filters) {
            $filters->custom("drawtext=fontfile=S:/Freelancer/version58trials/version58trials/public/webfonts/arial.TTF:text='Stack Overflow':fontcolor=white:fontsize=24");
          })
          ->export()
          ->toDisk('public')
          ->inFormat($format)
          ->save("watermark_video_added.mp4");


  


  And this is error I am getting :

  What I tried, is manipulating that filter function but I couldn't make it.

  


  For your knowledge,the video paths and font path is correct the only issue is with ffmpeg adding watermark text logic.
