请教一下rk3588对avs和avs+是不是支持不是很好，或者不稳定？

[junlorgithub]

目前我在使用mpp在做avs+的解码项目，但是只能出来几帧正常的，其他都是错误的，已经被mpp忽略掉，
刚开始我以为是我的输入不正确，或者数据有问题。经过多次确认数据没有问题。输入也没有问题。就感觉是解码出现了问题，无法解码。解码器经常reset。

请问一下rk3588对avs和avs+的支持如何？我是否有其他没做对的地方。非希望得到大家的回复，感谢。

在最开始执行avs+解码会直接报断错误，后面发现avs+在kernel里面有设备树的配置，我打开以后就没有错误了，但是就是我上面说的情况，折腾好几天，一直没有解决，没有任何思路了。希望能得到支持。

使用demo程序日志如下：

有 AVS+ 解码的，但是 avs / avs+ 码流本身有不少语法混乱和兼容性问题，可以发码流上来看下
另外，把码流用 ffmpeg 过一下看看有没有报错

非常感谢你的回复，确实在代码里面是有avs+解码的。但是也确实只能解几帧，大部分是错误的。我把我avs es流发你给你。麻烦你测试一下，我使使用支持avs+的ffmpeg是可以正常解码的。这个数据是我从广电现有节目里面弄出来的。

@HermanChen 我不知道是否是网络问题。上传文件一直失败，麻烦你稍等一下。

可以到公司的 redmine 上去报问题，国内网络上传容易

@HermanChen 我自己写代码测试avs+出现解码失败类似情况以后，我就使用你们的demo程序进行了测试。
mpi_dec_test -i avs_es.avs -w 720 -h 576 -t 16777221 -o avs3.yuv

@HermanChen 有测试结果吗？

原版的ffmpeg只支持 avs，这个片源是 avs+,你是用了哪个解码器可以正常解码的？

有修改过ffmpeg，支持avs+的。你需要吗，我给你一份，也是别人给我的。window编译好的。

@HermanChen 有进展吗？能否提供点支持和帮助，谢谢！
