求助急:音频模块部分细节问题(ar0130)
1.最近在调音频模块,调了快一个月了,没找到原因,关键是不知道哪里出问题了,按理说例程应该是可以的,这里有些小疑问,还请各们大侠帮忙看一下:)
例程位于开发文档中的:/mnt/mpp/sample/audio/sample_acodec, cat一下C文件,这里有个变量声时如此: static HI_BOOL gs_bMicIn = HI_FALSE; 因为我用的测试设备是有源麦克风(电脑麦克风那种),这里是否要更改为HI_TRUE,后面有改过调试问题同样存在,帮忙理一下,这里放一下调试proc给大伙看看:
/mnt/mpp/sample/audio
# ./sample_audio
/************************************/
press sample command as follows!
1: send audio frame to AENC channel form AI, save them
2: read audio stream from file,decode and send AO
3: start AI to AO loop
q: quit whole audio sample
sample command:1
Ai(0,0) bind to AencChn:0 ok!
open stream file:"audio_chn0.adpcm" for aenc ok
bind adec:0 to ao(0,1) ok
please press twice ENTER to exit this sample(到这里喊话没有声音,不管是选择123)。接者:

请问大哥们,这到底是什么原因呢,还有我的# cat /dev/log为什么没有反应呢,log文件是粉红色的文件夹,呀呀,快疯了。
