From dfe5563f80041b9dcd62e8f03054919e3e844d5f Mon Sep 17 00:00:00 2001 From: lichaofan Date: Thu, 19 Mar 2026 15:09:53 +0800 Subject: [PATCH] feat: enable the configuration for the preferred resolution. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use the DConfig mechanism to enable the configuration for the preferred resolution. 使用DConfig机制，开放首选分辨率的配置功能。 Task: https://pms.uniontech.com/task-view-387315.html --- libcam/libcam_v4l2core/v4l2_core.c | 48 +++++++++++++++++---- libcam/libcam_v4l2core/v4l2_formats.c | 55 ++++++++++++++++++++++++ libcam/libcam_v4l2core/v4l2_formats.h | 37 ++++++++++++++++ src/assets/org.deepin.camera.encode.json | 10 +++++ src/main.cpp | 12 ++++++ src/src/basepub/datamanager.cpp | 47 ++++++++++++++++++++ src/src/basepub/datamanager.h | 14 ++++++ 7 files changed, 214 insertions(+), 9 deletions(-) diff --git a/libcam/libcam_v4l2core/v4l2_core.c b/libcam/libcam_v4l2core/v4l2_core.c index bcb1830f..4da187c3 100644 --- a/libcam/libcam_v4l2core/v4l2_core.c +++ b/libcam/libcam_v4l2core/v4l2_core.c @@ -1696,20 +1696,50 @@ void v4l2core_prepare_valid_resolution(v4l2_dev_t *vd) } } - // 查找可以支持的最大分辨率 - // 由于上游guvcview项目在解码3840x2160分辨率以上时会出现异常（出现条纹、崩溃等），所以我们需要限制可用分辨率到3840x2160 - printf("V4L2_CORE: valid resolution counts: %d\n", vd->list_stream_formats[format_index].numb_res);
