AecSdkDemo #7

Closed PeadarO closed 4 years ago

PeadarO commented 5 years ago

I am looking at AecSdkDemo and it really is very good. I am trying to compress the output of it. I can compress it with LAME but there is an annoying delay with LAME when I send the compressed voice through a socket to another computer. I would like to use another encoder, most likely FFMPEG. Most encoders seem to need an 8 bit input. Is there any way of getting AecSdkDemo to produce an 8 bit output? In AecSdkDemo I have changed this...... WAVEFORMATEX wfxOut = { WAVE_FORMAT_PCM, 1, 8000, 16000, 2, 16, 0 }; to this..... WAVEFORMATEX wfxOut = { WAVE_FORMAT_PCM, 1, 8000, 8000, 1, 8, 0 };

but the SetOutputType then returns a DMO_E_TYPE_NOT_ACCEPTED

I have downloaded a load of other programs and used their 8-bit versions of WAVEFORMATEX but they all give me the same error in AecSdkDemo.

Thanks in advance for any help
