Audio.AddFrame(float[][]) throw invalid argument exception #97

Closed Horiztar closed 2 years ago

Horiztar commented 2 years ago

Sorry but I didn't find a document about this.

First, I create an output:

MediaBuilder.CreateContainer("").WithAudio(new AudioEncoderSettings(44100, 2)
{
        Bitrate = 320000, SamplesPerFrame = 735     // the video should be 60 fps, so I assume it was 44100/735
}).WithVideo(new VideoEncoderSettings(1920,1080,60)).Create();

Here is how I used this method:

Video.AddFrame(ImageData);
Audio.AddFrame(buffers);    // buffers: byte[2][735]

And Audio.AddFrame throw

FFMediaToolkit.FFmpegException:“Cannot send a frame to the encoder. Error code: -22 : Invalid argument”

What did I do wrong?
