Error in bridge.cpp when using openh264

[Alpe6825]

I implement custom video encoders for pion webrtc like this:

func CreateCustomOpen264Encoder() codec.ReadCloser {
	// Your image data (replace this with your image loading logic)
	customVideoReader := NewCustomVideoReader2()
	open264Params, _ := openh264.NewParams()
	mediaProp := prop.Media{
		//DeviceID: "",
		Video: prop.Video{
			Width:                  350,
			Height:                 350,
			FrameRate:              25,
			FrameFormat:            frame.FormatRGBA,
			DiscardFramesOlderThan: 0,
		},
		//Audio:    prop.Audio{},
	}

	open264Encoder, err := openh264Params.BuildVideoEncoder(&customVideoReader, mediaProp)
	if err != nil {
		println("Error BuildVideoEncoder")
	}

	return open264Encoder
}

It works for vp8, vp9 and x264, but open264 throws the following error:
