From b982dd0d8366b2cb9cc6288b821a536c8e2b50ed Mon Sep 17 00:00:00 2001 From: Philip Langdale Date: Fri, 19 Aug 2022 17:01:07 -0700 Subject: lavc/vaapi: Add support for remaining 10/12bit profiles With the necessary pixel formats defined, we can now expose support for the remaining 10/12bit combinations that VAAPI can handle. Specifically, we are adding support for: * HEVC ** 12bit 420 ** 10bit 422 ** 12bit 422 ** 10bit 444 ** 12bit 444 * VP9 ** 10bit 444 ** 12bit 444 These obviously require actual hardware support to be usable, but where that exists, it is now enabled. Note that unlike YUVA/YUVX, the Intel driver does not formally expose support for the alphaless formats XV30 and XV360, and so we are implicitly discarding the alpha from the decoder and passing undefined values for the alpha to the encoder. If a future encoder iteration was to actually do something with the alpha bits, we would need to use a formal alpha capable format or the encoder would need to explicitly accept the alphaless format. --- Changelog | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'Changelog') diff --git a/Changelog b/Changelog index 70c12df8dc..f34e8e5d42 100644 --- a/Changelog +++ b/Changelog @@ -8,7 +8,7 @@ version : - ffmpeg now requires threading to be built - ffmpeg now runs every muxer in a separate thread - Add new mode to cropdetect filter to detect crop-area based on motion vectors and edges -- VAAPI decoding and encoding for 8bit 444 HEVC and VP9 +- VAAPI decoding and encoding for 10/12bit 422, 10/12bit 444 HEVC and VP9 - WBMP (Wireless Application Protocol Bitmap) image format - a3dscope filter -- cgit v1.2.1
