• avfilter/vf_libplacebo : add `reset_sar` option

  16 juin, par Niklas Haas

  avfilter/vf_libplacebo : add `reset_sar` option
  This was requested by users of `vf_libplacebo`, to mirror the existing
  
  option on the other `vf_scale_*` family of filters. While we have
  
  `vf_normalize`, it was not as useful in the event that the content
  
  stretching was actually desired.
  Bridges an important usability gap between `vf_scale` and `vf_libplacebo`
  
  that made mixing and matching the filters needlessly difficult.

• how to encoded a 10bit .tif file into an HDR video by ffmpeg in command line [closed]

  6 juin 2024, par ziyuan

  how can i encoded a RGB 10 bit tif file into a hdr video by ffmpeg ?

  


  and one more question : should the input tiff must be 16bit big- or little- endian ?

  


  i have try the method here : How can I encode RGB images into HDR10 videos in ffmpeg command-line ?
,the same command and setting as the method. However i got this : code 1026 : YUV color family cannot have RGB matrix coefficients

  


  here is the tiff file i have tried :https://drive.google.com/file/d/1G8oYf9-FQJJPNUxwB0_FmlvBaMnUhCVL/view?usp=drive_link

  


  and i found that :
the procedure information it seems like the ffmpeg automatically set the output format as gbrp16le even when i set the -pix_fmt yuv420p10le.

  


• Usurper of FATE

  31 juillet 2010, par Multimedia Mike — FATE Server

  Mans sent a message to the FFmpeg-devel list today :

  A new FATE

  Mike’s FATE system has done a great job over the last few years. It
  is however beginning to prove inadequate in various ways :

  [various shortcomings already dissected at length on this very blog]

  To address the above-mentioned issues, I have been working on a
  replacement system which is now ready to be announced.

  Check it out : http://fate.ffmpeg.org/.

  Considering that he just obsoleted something I’ve poured a lot of time and energy into over the last 2.5 years, is my first reaction to this news supposed to be unbridled joy ? Hey, I’m already on record as stating that I wouldn’t mind throwing away all of FATE if there was a better alternative.

  I’m not certain but I’m pretty sure that at this point, the original FATE server is practically obsolete. Mans is already testing all of his configurations as well as the configs I test. As soon as the other FATE installations switch over to the new server, I should be able to redirect fate.multimedia.cx -> fate.ffmpeg.org, sell most of my computers, and spend more time with my family.

  Thanks, Mans !
