• Convert png images to HEVC with alpha video via ffmpeg [closed]

  6 mai 2024, par foxhable

  I am trying to create a video from a sequence of png images in the HEVC with alpha codec via ffmpeg.

  


  After the command

  


  ffmpeg -i a%d.png -r 30 -c:v hevc_videotoolbox -allow_sw 1 -alpha_quality 1 -vtag hvc1 ffmpeg-hevc.mov


  


  I get a video with a transparent background that opens in QuickTime, but not Safari.

  


  Info about this video via ffprobe :

  


  ffprobe .\ffmpeg-hevc.mov
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\ffmpeg-hevc.mov':
  Metadata:
    major_brand     : qt
    minor_version   : 512
    compatible_brands: qt
    encoder         : Lavf61.3.103
  Duration: 00:00:12.77, start: 0.000000, bitrate: 3437 kb/s
  Stream #0:0[0x1]: Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bottom coded first (swapped)), 1920x1920, 3435 kb/s, 30 fps, 30 tbr, 15360 tbn (default)
      Metadata:
        handler_name    : VideoHandler
        vendor_id       : FFMP
        encoder         : Lavc61.5.103 hevc_videotoolbox


  


  I compared this to a video that has a transparent background and works in Safari and QuickTime

  


  ffprobe movie-hevc.mov
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '.\movie-hevc.mov':
  Metadata:

      Metadata:
        creation_time   : 2021-01-02T10:33:38.000000Z
        handler_name    : Core Media Video
        vendor_id       : [0][0][0][0]
        encoder         : HEVC


  


  The only thing I noticed is the encoder. In the working version this is HEVC but in my Lavc61.5.103 hevc_videotoolbox.

  


  The question is, is it possible to create a video with a native HEVC codec via ffmpeg ?
