• Transcoding ERROR : jellyfin-ffmpeg/lib/dri/iHD_drv_video.so init failed

  24 mars 2023, par Souleimen BENTRAIFA

  Here is my problem, I switched from Jellyfin Win10 to Jellyfin via OMV6 Portainers (official images).
I have I7-2600S (VAAPI)

  


  Except that the transcoding doesn't work anymore, in the Jellyfin logs I have the following error message :

  


  [h264_vaapi @ 0x557ec1743400] No usable encoding entrypoint found for profile VAProfileH264High (7).
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


  


  In the attachment you will find information after the "vainfo" we have the following error

  


  screenshot vainfo command here

  


  libva error: /usr/lib/jellyfin-ffmpeg/lib/dri/iHD_drv_video.so init failed


  


  If anyone has a clue, let me know

  


  NOTE : In Windows 10 i have no problem to transcoding in any format

  


• FFMPEG via PHP - no thumbnail or log output generated

  10 octobre 2018, par Utkanos

  I’m trying to get my head around command line syntax in the form of FFMPEG via PHP.

  I’ve successfully installed it and I can use it fine, until I try to :

  • run background tasks
  • generate output to a log

  This code attempts to create a thumbnail from a video. And it does, if I make it synchrnous, i.e. remove everything from onwards code>....

  shell_exec($i = 'ffmpeg -y -i '.$fp.' -ss '.$secs.' -vframes 1 '.$dirs_path.'/thumb.png  null >/dev/null 2>/ffmpeg.txt &');

  I’ve derived the background part of this command from this page on the official FFMPEG site.

  ($secs is an integer denoting a seconds point within the video duration, and $fp is the save path of the video. Both are valid.)

  So the thumb doesn’t get generated, and there’s no ffmpeg.txt created, either in the place where the script runs, or in the server root or anything. I may be looking in the wrong place... I’m unsure what all this is relative to.

  Any help appreciated.

• Convert video to HLS in iOS app without triggering GPL (FFmpegKit alternative ?) [closed]

  7 juillet, par Aziz Bibitov

  I'm building an iOS app in Swift that needs to convert local video files to HLS format (.m3u8). Initially, I used the ffmpeg-kit-ios-full-gpl package from FFmpegKit, which works well. However, since this build includes GPL-licensed components (such as libx264), I'm concerned that using it would require my app to be released under the GPL, which is not compatible with App Store distribution.

  


  That said, my needs are fairly basic : I only need to convert H.264 .mp4 video files into HLS format.

  


  My Questions :

  


  

  1. Is there a safe way to use FFmpegKit—such as the full-libarary-lgpl variant—that guarantees no GPL components are used for this task ?

  


  2. Are there any iOS-native or third-party tools that can reliably convert H.264 .mp4 video files to HLS on-device without introducing GPL concerns ?

  


  3. Is using Apple’s AVAssetExportSession a viable alternative for exporting to HLS ? I haven't found much official documentation about using it for HLS output.

  


  


  Any guidance on how to perform HLS conversion in an App Store–safe (non-GPL) way would be much appreciated.
