解码H264视频没问题，但是解码jpg图片会抛出段错误异常 "mpp_dec_parser" received signal SIGSEGV, Segmentation fault.

[FumasterLin]

本地测试没问题 1、git log看一下 2、如何复现的？

commit 49f29006a3c728bb3570279b7b5407ec29e09f6d

就是使用rkmedia中的rkmedia_vdec_test.c测试发现的，视频解码时没有问题的，但是JPG解码就不行。mpp version: 2ceca7b5 author: sayon.chen 2021-07-01 [hal_jpege_vpu]: Fix qtable memory leak这个版本是OK的

[qvoid]

有没有完整的崩溃的调用栈信息？使用mpi_dec_test是否有问题？

[jiale-gdyd]

只能看到这个。根据mpp_dec_parser这个，应该是mpp/codec/mpp_dec.cpp --> void *mpp_dec_parser_thread(void *data)这个线程出现问题了

[qvoid]

可以编译个debug库试试看。还有用

mpi_dec_test -i <input.jpg> -t 8 -w <width> -h <height>

看下解码有没有问题。

mpi_dec_test 在MPP的编译后的build/linux目录下可以找到

这个倒是不会崩溃，但是也解不了码

[HermanChen]

这个是什么芯片平台？跑下 mpp_platform_test

[jiale-gdyd]

是RV1126，SDK是1.7.0

[jiale-gdyd]

你们那边有RV1126的EVB板吗？在板上更换最新编译的mpp库，在板子上跑jpg解码正常吗？

[HermanChen]

加这个补丁看看 8ca5be7.diff.zip

[jiale-gdyd]

额，打了补丁后还是一样的问题

[HermanChen]

有出错 log 么？

[jiale-gdyd]

这个版本是正常的

[HermanChen]

了解，可以二分法试下看看哪个版本出现的问题…… 我们这边测试 https://github.com/hermanchen/mpp/ 这里的最新版本应该是好的

[drm]: Add DRM_CLOEXEC|DRM_RDWR flag on fd import …

1. Add drm fd open flag.
2. Remove unused handle process on mmap. Change-Id: Id0b29b8914c1e8e8ae6af40877df21f73b46346e Signed-off-by: Jeffy Chen [email protected] @HermanChen HermanChen committed on 15 Jul

刚试了下，从这个开始(包括这个)d到最新的不行了

[HermanChen]

了解，这个补丁后面还有几个 drm 的补丁，主要是修改 drm fd 打开时候的访问权限问题

[HermanChen]

可能外部分配的 buffer 也要修改下。

[jiale-gdyd]

现在可以用的这个CPU占用比较高

[jiale-gdyd]

请问下，这个问题啥时候能修好呢?

[Jeffwhen]

我碰到了一样的问题，我去看了一下代码，意思是如果解码 jpeg 输出要是默认以外的格式都要使用 PP 结尾的解码器？

rv1126 的支持列表里面没有 PP 结尾的解码类型，意思是 rv1126 的 VPU 硬件上不支持 post process 吗？

[HermanChen]

测试试一下 https://github.com/hermanchen/mpp/ 这里的最新版本，看看还会不会有问题

[HermanChen]

如果没有问题，我就把开发分支的版本同步过来

[Jeffwhen]

@HermanChen 还是有问题

@HermanChen 我应该升级内核么？我看是系统调用报的错。

[HermanChen]

看下编译的时候有没有加上 HAVE_DRM？
