看其他帖子知道；dmesg 没又看到相应的日志输出。日志输出也打开了。命令用的是 echo 0x0100 > /sys/module/rk_vcodec/parameters/debug 想知道，解码失败的原因是什么，输出一直为0

功课做得很不错：）

mpi_dec_test -i /home/big_buck_bunny_480p.mp4 -t 8 -n -1 -w 640 -h 480 mpi_dec_test 是解祼码流的，不能解 mp4 这种带封装的格式，需要把 mp4 文件里的 264 raw 数据解出来才能解用 ffmpeg 抽一下码流 ffmpeg -i big_buck_bunny_480p.mp4 -vcodec copy -an -bsf h264_mp4toannexb big_buck_bunny_480p.h264 然后把 264 码流给解码器还有，264 的 mpi_dec_test 参数是 -t 7，不是 -t 8，8 是 jpeg

关于封装和祼码流，还有 ffmpeg 使用，建议去雷神的博客里学习 https://blog.csdn.net/leixiaohua1020

好的，随后去测试。感谢。

为什么解码不成功，哪里出问题了？

上层解码过程正常，说明码流应该是对的，可能是内核驱动的匹配问题像楼主一样提供下环境相关的信息

这是我的环境相关的信息

麻烦提供下 test.h264 测试源

麻烦提供下 test.h264 测试源

test.zip 麻烦您了

mpp_dec_test.log 你好，我用的楼上提供的264源解码测试的。提示解码成功，但是我在windows端使用 yuvplayer播放的时候，全部是绿屏。log是实际的测试文件

确认是有问题，估计最新版本的 mpp 对旧内核的兼容性有问题，我们查一下问题你们可以先把 mpp 回退一些版本看看

https://github.com/HermanChen/mpp/ 试一下这里的 develop 分支有没有问题

https://github.com/HermanChen/mpp/ 试一下这里的 develop 分支有没有问题

测试 release_20171218 tag 测试。编译还是之前的问题。解码数据为0. 内核架构：Architecture: armv7l mpp_dec_test_release_20171218.log

https://github.com/HermanChen/mpp/ 试一下这里的 develop 分支有没有问题

这个分支测试还是同样的问题。

我测试了下，Android 的 4.4 内核是正常的 firefly 是 linux 平台上的内核，由不同产品部维护，我找人看一下是不是内核驱动有差异导致的问题。

下边是1107 tag 的输出日志 mpp_dec_test_release_20171107.log

我测试了下，Android 的 4.4 内核是正常的 firefly 是 linux 平台上的内核，由不同产品部维护，我找人看一下是不是内核驱动有差异导致的问题。

好的。感谢

把问题发到 firefly 论坛上去看看，我们手上没有 firefly 的固件，比较麻烦，需要核对下内核 vcodec 相关的代码

您好，在firefly论坛并没有人回复，相关资料也很少。只有gstream调用mpp相关的。您说的核对内核源码具体需要怎么操作，我这边尝试一下

同样的问题，RK3588解码失败，mpi_test 也报失败 mpp[8567]: mpi_test: mpi_test start mpp[8567]: mpi_test: mpi_test decoder test start mpp[8567]: mpi: mpp_create enter ctx 0x7fcd645488 mpi 0x7fcd645490 mpp[8567]: mpp_info: mpp version: 3c5dc7fe author: sayon.chen 2020-11-23 [h265d_syntax]: Fix h265 syntax fill sps rps issue mpp[8567]: mpi: mpp_create leave ret 0 ctx 0x5575b9b4e0 mpi 0x7fa98d8af8 mpp[8567]: mpi: mpp_init enter ctx 0x5575b9b4e0 type 0 coding 0 mpp[8567]: mpp: unable to create unsupported type 0 coding 0 mpp[8567]: mpi: mpp_init leave ret -1 mpp[8567]: mpi_test: mpp_init failed mpp[8567]: mpi: mpp_destroy enter ctx 0x5575b9b4e0 mpp[8567]: mpi: mpp_destroy leave ret 0 mpp[8567]: mpi_test: mpi_test failed

用的什么参数，没定义输入格式

rockchip-linux / mpp

mpi_dec_test 解码失败 #188
