Ich habe herumgesucht und mehrere Vorschläge ausprobiert, wie ein aufgenommenes Video ohne Erfolg zu einem ImageView angezeigt werden kann.Android: Wie wird die Video-Miniaturansicht in ImageView angezeigt?
Dieser Code funktioniert einwandfrei, um ein Bild aufzunehmen und das Bild anzuzeigen. Das Video wird ebenfalls aufgezeichnet und auf dem Telefon gespeichert, aber es wird nicht in ImageView angezeigt. Irgendwelche Vorschläge, wie ich meinen Code hier ändern kann, damit das Video im ImageView erscheint?
Es scheint alles gut zu funktionieren neben dem Abschnitt: RESULT_LOAD_VID, der das ausgewählte oder aufgezeichnete Video im ImageView anzeigen soll.
Der Fehler, den ich erhalten ist: „SkImageDecoder :: Fabrik zurück null“
Von dem, was ich verstehe, bedeutet dies, dass aus irgendeinem Grund die gewählte/aufgenommenen Videos Lage ist nicht an den RESULT_LOAD_VID Abschnitt geleitet zu werden.
Jede Hilfe wird geschätzt.
Hier ist mein aktueller Code:
public class Media extends AppCompatActivity{
private static int RESULT_LOAD_IMG = 1;
private static int RESULT_LOAD_VID = 1;
String imgDecodableString;
private String selectedImagePath = "";
private static final int CAPTURE_VIDEO_ACTIVITY_REQUEST_CODE = 200;

private ImageView mImageView;
Toolbar toolbar;
private String imgPath;
