* h265 encoding: the second frame always fails, use repeat encoding to achieve real-time encoding * h264 encoding: Not supported because encoding fails too frequently, about 50%, with one failure followed by another success. * h264/h265 decoding: No issues found. * Does not support dynamically changing the bitrate and changing the quality by resetting the encoder.
