我是靠谱客的博主激动水壶，最近开发中收集的这篇文章主要介绍camera ISP问题梳理，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

error log:

E/mm-camera( 809): <ISP   ><ERROR> 331: isp_stats_buf_mgr_get_buf: failed: could not find stats instance
E/mm-camera( 809): <ISP   ><ERROR> 416: isp_parser_thread_process: failed: get buf failed

E/mm-camera( 809): <ISP ><ERROR> 710: isp_parser_thread_func: failed: isp_parser_process

修改方案：

vendor/qcom/proprietary/mm-camera/mm-camera2/media-controller/modules/isp2/common/isp_defs.h

#define MAX_STATS_BUFFERS 定义值改大。尝试继续复现

修改方案：

kernel/msm-3.18/drivers/media/platform/msm/camera_v2/ispif/msm_ispif.c

修改：ispif->reset_complete[VFE0], msecs_to_jiffies(500)

ispif->reset_complete[VFE1], msecs_to_jiffies(500) 等待时间修改

原因是拍照的过程中ISP一直没有数据返回，后续close camera时出现crash
