i'd appreciate a second pair of eyes on this patch: it tries to enable support for kCVPixelFormatType_422YpCbCr8_yuvs mapped to AV_PIX_FMT_YUYV422. it is an attempt to fix a bug in qtmultimedia when feeding video frames using kCVPixelFormatType_422YpCbCr8_yuvs into ffmpeg. context: https://bugreports.qt.io/browse/QTBUG-137436 any thoughts if this goes into the correct direction? >From 7c01c559d47210bcc231d95ee62d5246218a8b15 Mon Sep 17 00:00:00 2001 From: Tim Blechmann <[email protected]> Date: Tue, 24 Jun 2025 12:27:05 +0800 Subject: [PATCH] CoreVideo: add support for kCVPixelFormatType_422YpCbCr8_yuvs --- configure | 1 + libavutil/hwcontext_videotoolbox.c | 6 ++++++ 2 files changed, 7 insertions(+) diff --git a/configure b/configure index 7828381b5d..a323492b9b 100755 --- a/configure +++ b/configure @@ -2531,6 +2531,7 @@ TYPES_LIST=" kCVPixelFormatType_444YpCbCr8BiPlanarVideoRange kCVPixelFormatType_444YpCbCr10BiPlanarVideoRange kCVPixelFormatType_444YpCbCr16BiPlanarVideoRange + kCVPixelFormatType_422YpCbCr8_yuvs kCVImageBufferTransferFunction_SMPTE_ST_2084_PQ kCVImageBufferTransferFunction_ITU_R_2100_HLG kCVImageBufferTransferFunction_Linear diff --git a/libavutil/hwcontext_videotoolbox.c b/libavutil/hwcontext_videotoolbox.c index 102fa485e5..2764097413 100644 --- a/libavutil/hwcontext_videotoolbox.c +++ b/libavutil/hwcontext_videotoolbox.c @@ -82,6 +82,9 @@ static const struct { #if HAVE_KCVPIXELFORMATTYPE_444YPCBCR16BIPLANARVIDEORANGE { kCVPixelFormatType_444YpCbCr16BiPlanarVideoRange, false, AV_PIX_FMT_P416 }, #endif +#if HAVE_KCVPIXELFORMATTYPE_422YPCBCR8_YUVS + { kCVPixelFormatType_422YpCbCr8_yuvs, false, AV_PIX_FMT_YUYV422 }, +#endif }; static const enum AVPixelFormat supported_formats[] = { @@ -112,6 +115,9 @@ static const enum AVPixelFormat supported_formats[] = { #endif #if HAVE_KCVPIXELFORMATTYPE_444YPCBCR16BIPLANARVIDEORANGE AV_PIX_FMT_P416, +#endif +#if HAVE_KCVPIXELFORMATTYPE_422YPCBCR8_YUVS + AV_PIX_FMT_YUYV422, #endif AV_PIX_FMT_BGRA, }; -- 2.49.1 _______________________________________________ ffmpeg-devel mailing list -- [email protected] To unsubscribe send an email to [email protected]
