基本信息
targetSdk版本28
目标：该类的目标是在发送到我的服务器之前调整视频的大小。
问题：应用程序仅在API 29上崩溃，无论是使用真实设备还是使用AVD。例如，代码在像素2 API 28上运行良好，但在像素2 API 29上运行不正常
源代码：我主要使用bigflake.com.中的示例代码
错误消息(详细日志如下(：
E/AndroidRuntime: FATAL EXCEPTION: Thread-20

我尝试过的由于MediaCodec$CodecException的日志信息有限，我尝试过从MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface更改为MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible，但没有成功。
日志将显示最后两个缓冲周期。我希望你能看到一些有价值的东西。

我认为正确的方法是在xxxxExtractor.advance()返回false后让它进行另一个循环。
我修改了代码，只在xxxxExtractor.readSampleData返回的大小返回-1之后标记提取器完成。这样，您就知道要发送到queueInputBuffer的缓冲区是空的。
因此：xxxxExtractorDone = !xxxxExtractor.advance();->xxxxExtractorDone = !xxxxExtractor.advance() && size == -1;
我也使用过Bigflake代码，并在Android10(API 29(中运行过该代码。
其他相关问题也很有帮助，但不要直接回答如何修改Bigflake代码的问题。在花了几个小时之后，这就是我想到的。
对于视频和音频，在doExtractDecodeEditEncodeMux内，之前
xxxxxDecoder.queueInputBuffer(
decoderInputBufferIndex,
0,
0,
0,
MediaCodec.BUFFER_FLAG_END_OF_STREAM);
如果调用，则需要添加以下代码行，以确保使用空缓冲区发送EOS。
// wait forever for a new buffer
decoderInputBufferIndex = xxxxxDecoder.dequeueInputBuffer(-1);
有两个这样的例子，视频的最终代码看起来是这样的，给出了大部分上下文：
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");
}
希望这能帮助其他陷入困境的人。
我遇到了同样的问题，并最终解决了它。我使用了asynctaskMode和编解码器回调。
while (!mAudioExtractorDone) {
int size = mAudioExtractor.readSampleData(decoderInputBuffer, 0);
long presentationTime = mAudioExtractor.getSampleTime();
MLog.i(TAG, "audio extractor: ronInputBufferAvailable() presentationTime = " + presentationTime);
if (size >= 0) {
codec.queueInputBuffer(index, 0, size, presentationTime, mAudioExtractor.getSampleFlags());
}else {
Log.e(TAG, "onInputBufferAvailable: " + "size < 0 = " + size);
codec.queueInputBuffer(index, 0, 0, 0L, MediaCodec.BUFFER_FLAG_END_OF_STREAM);
mAudioExtractorDone = true;
}
mAudioExtractor.advance();
mAudioExtractedFrameCount++;
logState();
当大小小于零时发送BUFFER_FLAG_END_OF_STREAM。注意循环的标记位(mAudioExtractorDone(。
