MediaRecorder: stop failed: -1007

java.lang.RuntimeException: stop failed. at Method)

该异常会在部分机型出现,当录制完毕后,执行 stop() 函数时出现异常。 解决思路:

  1. 检查 MediaRecorder 的视频输出尺寸是否是系统所支持的尺寸
  2. 修改 Camera 的预览尺寸与 MediaRecorder 的视频输出尺寸一致
  3. 修改 MPEG_4_SP 为 H264 mRecorder?.setVideoEncoder(MediaRecorder.VideoEncoder.MPEG_4_SP) -> mRecorder?.setVideoEncoder(MediaRecorder.VideoEncoder.H264)

stop failed 的另一种情况

读者反馈当录制视频时间过短时或出现崩溃的情况,就此我们可以参考 stop() 方法的备注:

     * Stops recording. Call this after start(). Once recording is stopped,
     * you will have to configure it again as if it has just been constructed.
     * Note that a RuntimeException is intentionally thrown to the
     * application, if no valid audio/video data has been received when stop()
     * is called. This happens if stop() is called immediately after
     * start(). The failure lets the application take action accordingly to
     * clean up the output file (delete the output file, for instance), since
     * the output file is not properly constructed when this happens.
     * @throws IllegalStateException if it is called before start()
    public native void stop() throws IllegalStateException;



  1. try{}catch{} 捕获改异常,并提示用户录制时间太短,然后允许用户重新录制;
  2. 人为延时,在 stop() 方法调用前确定总时长,当总时长小于 1s 时,Thread.sleep(xxx)
You can’t perform that action at this time.
