MediaRecorder和VideoSource.SURFACE，停止失败:-1007(严重的Android错误) [英] MediaRecorder and VideoSource.SURFACE, stop failed: -1007 (a serious Android bug)

问题描述

我正尝试在不使用Camera实例但使用Surface视频源的情况下记录MediaRecorder(是可以的，但事实证明它并不那么完美)-mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);

I'm trying to record MediaRecorder without using Camera instance but using Surface video source (yes it's possible, but it turned out that it's not that perfect) - mediaRecorder.setVideoSource(MediaRecorder.VideoSource.SURFACE);

我只是写出什么问题:

下一个代码仅在某些设备上有效，并且在最近的设备重新启动后暂时不可用，或者在某些设备上暂时不可用

如果它不起作用，则MediaRecorder.stop()方法失败并显示下一个错误

If it doesn't work ok MediaRecorder.stop() method fails with the next error

E/MediaRecorder:停止失败:-1007 W/System.err:

E/MediaRecorder: stop failed: -1007 W/System.err:

java.lang.RuntimeException:停止失败.在

java.lang.RuntimeException: stop failed. at

android.media.MediaRecorder.stop(本机方法)

android.media.MediaRecorder.stop(Native Method)

记录器mp4文件太小(千字节)，无法播放

recorder mp4 file is too small size (kilobytes) and it can't be played

经过测试的设备:

适用于Lenovo P2，小米Mi A1

works on Lenovo P2, Xiaomi Mi A1

不适用于小米Redmi 5，索尼Xperia，小米Redmi 4 Prime

doesn't work on Xiaomi Redmi 5, Sony Xperia, Xiaomi Redmi 4 Prime

您也可以阅读我的代码中的注释以更好地理解问题

Also you can read comments in my code to understand the issue better

new Thread(() -> {

    MediaRecorder mediaRecorder = new MediaRecorder();

    File file = new File(Environment.getExternalStorageDirectory()

        Surface surface = mediaRecorder.getSurface();

        mediaRecorder.start();

        // record something (we can also record frames here from onPreviewFrame byte arrays)
        // e.g. convert raw frame byte[] to Bitmap using mb OpenCV and then draw bitmap on canvas
        // using canvas.drawBitmap(...)
        // here we record just blue background...
        for (int i = 0; i < 120; i++) { // 5 seconds, 24 fps
            Canvas canvas = surface.lockCanvas(null);

更新#1 似乎有些进展，可能是问题所在-代码问题(mp4/h264)

UPDATE #1 seems some progress what could be the issue - codes issue (mp4/h264)

在WEBM/VP8上效果更好，现在可以播放视频，但是fps出了点问题，它在比例中显示了1000

it works better with WEBM/VP8, videos can be played now, but something wrong with fps, it shows 1000 in proporties

mediaRecorder.setOutputFormat(MediaRecorder.OutputFormat.WEBM);
mediaRecorder.setVideoEncoder(MediaRecorder.VideoEncoder.VP8);

在使用

mediaRecorder.setAudioEncoder(MediaRecorder.AudioEncoder.VORBIS);

检查 Android MediaRecorder使用MP4/H264且分辨率大于720p时，停止时会崩溃 因此当您使用MediaRecorder和MediaProjection记录/捕获设备屏幕时也会发生(因为它也使用Surface ...)

check Android MediaRecorder crashes on stop when using MP4/H264 and a resolution bigger than 720p so it also happens when you use MediaRecorder and MediaProjection to record/capture device Screen (because it also uses Surface...)

更新2 是的，似乎vp8编解码器工作正常，但是webm容器的一个问题-没有声音！

UPDATE 2 yes seems vp8 codec works fine, but one problem for webm container - NO AUDIO!

笨拙的Android设备仅不支持VORBIS/OGG音频编码...

buggy Android just doesn't support VORBIS/OGG audio encoding... https://developer.android.com/guide/topics/media/media-formats#audio-formats

推荐答案

我想没有解决办法

因此答案:MediaRecorder/Android出现故障，或者移动公司在开发设备时并不关心所有Android功能

so the answer: MediaRecorder/Android is buggy or Mobile companies didn't care of all Android features while developing their devices

更新

MediaCodec还是画布上的越野车

mSurface = mMediaCodec.createInputSurface();
mSurface.lockHardwareCanvas()

它可以在更多使用MediaCodec的设备上使用，但仍然有些设备可能无法使用此方法正确录制视频

It works on much more devices with MediaCodec but still some devices may fail to record video correctly using this method

因此，最终答案:在使用MediaCodec或MediaRecorder时千万不要使用lockCanvas或lockHardwareCanvas，这是越野车..

So final answer: don't ever use lockCanvas or lockHardwareCanvas when working with MediaCodec or MediaRecorder, it's buggy..

唯一的方法-OpenGl ES
