#11107(avfilter:new): Enhancement Request: Improve VAAPI Color Type Detection for HDR Content

#11107: Enhancement Request: Improve VAAPI Color Type Detection for HDR Content -------------------------------------+------------------------------------- Reporter: Peyton Lee | Type: | enhancement Status: new | Priority: important Component: avfilter | Version: | unspecified Keywords: | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- **Summary:** I am encountering an issue where HDR content is being incorrectly detected as BT.709 color type when using VAAPI filter (scale_vaapi). I believe that the color type detection for VAAPI needs to be enhanced to properly handle HDR content. **Description:** While trying to play an HDR video using FFmpeg with VAAPI, the color type is mistakenly identified as BT.709 instead of the correct HDR color type (e.g., BT.2020). Specifically, in my test video: - Color Primaries = 9 (BT.2020) - Color Transfer = 16 (SMPTE2084) - Color Space = 1 (BT.709) In the function `vaapi_vpp_fill_colour_standard`, the best format is determined as BT.709. I believe the logic in this function should be enhanced to better handle such cases. **Suggested Enhancement:** Enhance the color type detection logic in the VAAPI module to correctly identify HDR color types. For example, additional checks of the transfer function (SMPTE2084 is often used in HDR content) to ensure accurate color type recognition for HDR content, especially in the `vaapi_vpp_fill_colour_standard` function. Thank you for considering this request. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11107> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
