为什么"MediaCodec CodecException"在"queueInputBuffer"中只在Android API 29上发生? [英] Why the "MediaCodec CodecException" in "queueInputBuffer" only happen on Android API 29?

问题描述

基本信息

targetSdkVersion 28

targetSdkVersion 28

目标:该课程的目的是在将视频发送到我的服务器之前调整其大小.

Goal: The objective of the class is to resize a video before sending to my server.

问题:无论是在实际设备上还是在使用AVD时，该应用程序仅在API 29上崩溃.例如，该代码可以在 Pixel 2 API 28 上正常运行，而不能在 Pixel 2 API 29

Problem: The app crashes only on API 29, whether with real devices or using AVD. For example, the code works fine on Pixel 2 API 28, but not on Pixel 2 API 29

源代码:我主要使用 错误消息(有关详细日志，请参见下文):

Error message (detailed log are atteched below):

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)

我尝试过的事情 由于MediaCodec$CodecException的日志信息有限，我尝试从MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface更改为MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible并没有成功.

What I have tried Due to the limited log info of MediaCodec$CodecException, I tried with no success changing from MediaCodecInfo.CodecCapabilities.COLOR_FormatSurface to MediaCodecInfo.CodecCapabilities.COLOR_FormatYUV420Flexible.

日志将为您显示最近的两个缓冲周期.希望您会看到有价值的东西.

The logs will show you the last two buffer cycles. I hope you'll see something of value.

我还使用了Bigflake代码，并在Android 10(API 29)中使用了该代码.

I have also used the Bigflake code and ran into this with Android 10 (API 29).

其他链接的问题很有帮助，但不要直接回答有关如何修改Bigflake代码的问题.花了几个小时之后，我才想到了这一点.

The other linked issues are helpful, but don't directly answer the question as regards how to modify the Bigflake code. After spending a couple of hours, this is what I came up with.

对于视频和音频，在doExtractDecodeEditEncodeMux之内

For both video and audio, within doExtractDecodeEditEncodeMux, prior to where

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

被调用，您要添加以下代码行，以确保使用空缓冲区发送EOS.

is called, you want to add the following line of code, which ensures that you use an empty buffer to send the EOS.

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

有两个这样的实例，视频的结果代码如下所示，其中给出了大多数上下文:

There are two such instances, and the resulting code for video looks like this, with most of the context given:

                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");
                }

希望这可以帮助其他任何陷入困境的人.

Hopefully that helps anyone else stumbling into this.
