为什么"MediaCodec CodecException“中的"queueInputBuffer”只发生在Android 29上？
为什么"MediaCodec CodecException“中的"queueInputBuffer”只发生在Android 29上？
提问于 2020-02-19 18:39:45
基本信息
targetSdkVersion 28
目标：类的目标是在发送到我的服务器之前调整视频的大小。
Problem：该应用程序只在API 29上崩溃，无论是使用实际设备还是使用AVD。例如，代码在Pixel 2 API 28上运行得很好，但在Pixel 2 API 29上却不起作用。
源代码：我主要使用来自bigflake.com的示例代码。
错误消息(详细日志见下文)：
E/AndroidRuntime: FATAL EXCEPTION: Thread-20
Process: com.myapp.myapp, PID: 9189
android.media.MediaCodec$CodecException: Error 0xfffffff3
at android.media.MediaCodec.native_queueInputBuffer(Native Method)
at android.media.MediaCodec.queueInputBuffer(MediaCodec.java:2450)由于的日志信息有限，我尝试了，但没有成功地从MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface更改为MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible。
日志将显示最后两个缓冲区周期。我希望你能看到有价值的东西。

我还使用了Bigflake代码，并在Android 10 (API 29)中遇到了这个问题。
其他链接的问题是有帮助的，但是不要直接回答关于如何修改Bigflake代码的问题。花了几个小时之后，这就是我想出来的。
用于视频和音频，在doExtractDecodeEditEncodeMux中，在
xxxxxDecoder.queueInputBuffer(
decoderInputBufferIndex,
0,
0,
0,
MediaCodec.BUFFER_FLAG_END_OF_STREAM);调用时，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);有两个这样的实例，生成的视频代码如下所示，并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");
}希望这能帮到其他人。

我遇到了同样的问题，并最终解决了。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)。
