Почему «MediaCode c CodecException» в «queueInputBuffer» происходит только на Android API 29?

targetSdkVersion 28

Цель : Цель класса - изменить размер видео перед отправкой на мой сервер.

Проблема : приложение вылетает только на API 29, будь то на реальных устройствах или с использованием AVD. Например, код отлично работает на Pixel 2 API 28 , но не на Pixel 2 API 29

Исходный код : я использую в основном Пример кода от bigflake.com .

Сообщение об ошибке (подробный журнал приведен ниже):

Что я пробовал Из-за ограниченной информации журнала MediaCodec$CodecException, я безуспешно пытался изменить значение с MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface на MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible.

В журналах будет отображаться последний два буферных цикла . Я надеюсь, что вы увидите что-то ценное.

Я также использовал код Bigflake и столкнулся с ним с Android 10 (API 29).

Другие связанные проблемы полезны, но не дают прямого ответа на вопрос о том, как изменить код Bigflake. Потратив пару часов, это то, что я придумал.

Для видео и аудио, в пределах doExtractDecodeEditEncodeMux, перед тем, как вызывается 

                 xxxxxDecoder.queueInputBuffer(
                            decoderInputBufferIndex,
                            0,
                            0,
                            0,
                            MediaCodec.BUFFER_FLAG_END_OF_STREAM);

, вы хотите добавить следующую строку кода, которая гарантирует, что вы используете пустой буфер отправить EOS. 

                    // wait forever for a new buffer
                    decoderInputBufferIndex = xxxxxDecoder.dequeueInputBuffer(-1);

Существует два таких экземпляра, и результирующий код для видео выглядит следующим образом, с большей частью заданного контекста: 

                videoExtractorDone = !videoExtractor.advance();
                if (videoExtractorDone) {
                    if (VERBOSE) {
                        final String log = "Video extractor: EOS";
                        Log.d(TAG, log);
                        emitLog(log);
                    }
                    Log.i(TAG, "WAITING indefinitely until an input video buffer for EOS is available");
                    // wait forever for a new buffer
                    decoderInputBufferIndex = videoDecoder.dequeueInputBuffer(-1); // this is the actually important line
                    videoDecoder.queueInputBuffer(
                            decoderInputBufferIndex,
                            0,
                            0,
                            0,
                            MediaCodec.BUFFER_FLAG_END_OF_STREAM);
                            Log.i(TAG, "Successfully sent video EOS");
                }

Надеюсь, это поможет кому-нибудь еще натыкаюсь на это.
