我想重新錄製30秒的背景中的許多視頻，但在20或30個視頻後，我的服務將停止並啓動緩慢錄製過程。錯誤錄製視頻android
我在同一個過程中嘗試使用服務，問題是一樣的。
我的視頻處理程序：
@Override
public void onCreate() {
super.onCreate();
isRunning = true;
idAlerta = Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "");
videoCount = 1;
mIntentRecorder = new Intent(VideoHandlerService.this, RecorderService.class);
mIntentSend = new Intent(VideoHandlerService.this, SendVideoService.class);
updateVideoTime();
mIntentRecorder.putExtra(Constants.VIDEO_TIME, videoTime);
mIntentRecorder.putExtra(Constants.ID_ALERTA_SERVICE, idAlerta);
mIntentRecorder.putExtra(Constants.COUNT_ALERTA, videoCount);
startService(mIntentRecorder);
newVideo();
}
public void newVideo() {
Common.log("new Video");
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
videoCount++;
startNewVideo();
if (videoCount == 2)
sendVideo(4000);
}
}, videoTime + 2000);
}
public void startNewVideo() {
final Intent intentRecorder = new Intent(VideoHandlerService.this, RecorderService.class);
intentRecorder.putExtra(Constants.VIDEO_TIME, videoTime);
Common.log("idAlerta " + idAlerta);
intentRecorder.putExtra(Constants.ID_ALERTA_SERVICE, idAlerta);
intentRecorder.putExtra(Constants.COUNT_ALERTA, videoCount);
stopService(intentRecorder);
if (Common.getStorage().getBoolean(Constants.RECORDER_ACTIVE, false)) {
if (Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "") != null && Common.getStorage().getString(Constants.ID_ALERTA_SERVICE, "").length() > 0) {
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Common.log("Start service recorder");
startService(intentRecorder);
newVideo();
}
}, 5000);
}
} else
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
startNewVideo();
}
}, 5000);
}
這是過程記錄：
@Override

mVideoTime = intent.getIntExtra(Constants.VIDEO_TIME, 15000);

當我試圖停止服務停止服務，但攝像頭沒有被釋放甚至殺害應用程序。有人能幫我嗎？？提前致謝。 `camera.release後`（;
你可以嘗試添加'攝像頭= NULL更換
camera.lock()）;'。它可能解決問題。這裏更多的信息http://stackoverflow.com/questions/16705487/how-to-release-camera-after-activity-ends-in-android –謝謝，但我已經試過了，無論如何主要問題是不釋放並拍攝相機，主要問題是視頻本身停止錄製，沒有錯誤或異常，只是停下來，就像相機被凍結一樣 – javisilox
您應該在很多設備上進行測試，以便更好地瞭解您的問題。根據我的經驗，一臺相機可以表現得不同於另一臺相機。 – Nativ
