Is there a way to get Audio CMSampleBuffer?

[TalDabush]

Hi,
Im trying to get the audio sample buffers.
I tried to:

1. get AVaudioBuffer via RTMPStream delegate using this function:
   rtmpStream(_ stream: RTMPStream, didOutput audio: AVAudioBuffer, presentationTimeStamp: CMTime)
   but it never executes.
   (after some debugging I realized that the RTMPMuxer is the delegate of the AudioCodec and not the AVMixer which eventually triggers the RTMPStream delegate)

2. I saw this https://github.com/shogo4405/HaishinKit.swift/issues/575
   but unlike VideoEffect, the AudioEffect execute params doesn't include the sample
   is there a way to get the sample from the UnsafeMutableAudioBufferListPointer?

is there another way to get the audio sample?

Thanks in advance,

Hi. Yes you can get the UnsafeMutableAudioBufferListPointer.

• stream.registerAudioEffect(_ effect: AudioEffect)
• The AudioEffect interfaces are https://github.com/shogo4405/HaishinKit.swift/blob/9406e5de007e833b1bf40259051767522a74ab6f/Sources/Media/AudioEffect.swift

Hi, thank you for replying.
I saw that I can use
stream.registerAudioEffect(_ effect: AudioEffect)
to get UnsafeMutableAudioBufferListPointer,
what Im asking is -
Is there a way to get the CMSampleBuffer from the UnsafeMutableAudioBufferListPointer ?

OK. No way.
