Error in bridge.cpp when using openh264

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:
