hi3521的板子 运行sample_audio 好像没有采集到数据
please choose the case which you want to run:
1: start AI 8 chns to AO 1chn loop(NVP6134)
2: send audio frame to AENC channel from AI, save them
3: read audio stream from file, decode and send AO
4: start AI to AO(Hdmi) loop
q: quit whole audio sample
sample command:2
…
…
Ai(0,0) bind to AencChn:0 ok!
open stream file:”audio_chn0.aac” for aenc ok
bind adec:0 to ao(0,0) ok
这个的意思就是能够采集数据并且保存到aac文件了嘛
但是在/proc/umap的aenc里面没有任何数据 这个问题怎么解决呀各位大佬！！！
