由于mpp接收的数据格式为裸流文件,而对于本地视频文件可能为mp4等封装格式。考虑用ffmpeg解封装,但是解封装后该如何对接到mpp的接口?文档中有提到MppBuffer可用external模式,通过commit导入外部缓存,但是如果要commit一个AVPacket的话该如何让mpp能正确识别?

Hi,
I am transcoding two streams with h264_rkmpp encoder. But I got an error when my program called av_hwframe_transfer_data before encoded the frame. This is an occasional problem, I got some info…

- 可正常使用其他src node,但使用vp_rk_rtsp_src_node 时,没法正常读取视频数据

我使用ffmpeg 拉取rtsp流,并将packet数据交给mpp进行解码,
当视频流为h264时,我设置解码为 MPP_VIDEO_CodingAVC ,解码成功;
当视频流为h265时,我设置解码为 MPP_VIDEO_CodingHEVC,解码失败:
decode_get_frame获取的frame 一直是 none
按理说从h264切换为h265解码应该只要修改MPP_…

1:您的项目和官方ffmpeg-rtsp的项目区别在哪,为什么我能编译并运行通过您的项目,但是官方的跑不通
2:您项目中的ffmpeg拉流是否也采用mpp,也就是您的ffmpeg是否也是rk-ffmpeg,非官方的修改版本。
3:麻烦您给多路解码给一点建议,点通我就好。谢谢您

陈工您好:
我有几个问题请教,说一下前提。我目前手里3588是讯为的,拉取最新的mpp,可以执行测试程序。
第一:我想在rk3588上面主要做编解码开发,我通过./mpi_dec_test 测试性能基本满足,是不是意味着我板子上面的rga库是可以正常使用的,之前在3568上面开发因为rga驱动问题踩过坑。
第二:我测试了./mpi_dec_multi_test 32路 1…
