请教下，测试RK3588 H264硬件编码出来的帧都是I帧，是什么原因呢？
Closed this issue · 7 comments
35XX上测试RTP推流的功能，发现RK3568、3588系列的板子上硬件编码推流到播放端端无法被解码。
抓包H264裸流测试分析，RK3588 H264硬件编码出来的帧都是I帧，是什么原因呢，编码器需要做什么特殊配置吗？
相同的配置代码，Google的软编码器则正常。
MediaCodec配置：
MediaFormat mediaFormat = MediaFormat.createVideoFormat(MIME_TYPE_VIDEO, 720, 1280);
mediaFormat.setInteger(MediaFormat.KEY_BIT_RATE, 2500000);
mediaFormat.setInteger(MediaFormat.KEY_FRAME_RATE, 10);
mediaFormat.setInteger(MediaFormat.KEY_COLOR_FORMAT,
MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface);
mediaFormat.setInteger(MediaFormat.KEY_I_FRAME_INTERVAL, 10);
3588日志信息如下：

这个和系统上层相关，不是单纯的MPP问题，到公司redmine上提问吧，
KEY_FRAME_RATE 和 KEY_I_FRAME_INTERVAL 这两个参数自行修改下实验下吧
请问楼主3588的板子进行编解码的时候都会报错，您是用的哪个分支进行转码的
同时我的系统是Ubuntu 20.04
内核是5.10.110

您好，这个仍然有问题。请问有解决方法吗，同时vpu_api_test 测试失败

vpu_api_test 已经废弃了，不再维护，后面会删掉
mpp_dma_heap: Assertion fd > 0 failed at heap_fd_open:136
dma-heap 设备的权限问题，顺着 log 搜一下
