There are many video extensions, take a look here.
But you see, it works for you even if it doesn’t start automatically, otherwise, you would have also received error 701.
So the problem is something else, which I now believe has to do with how Koronakos’s phone interprets MP4 files, since some work and others don’t, maybe a codec issue? (im not an expert)
I’d really like to find the problem, and I’d ask you to try with adb logcat, but I understand not everyone wants to go crazy chasing an error, so it’s up to you whether to try with an extension.
Edit: Am I the only one seeing the google link in German?
I don’t understand why
“Bevor Sie zur Google Suche weitergehen” (Which translates to: “Before you proceed to Google Search”)
is a prompt or an interstitial page displayed by Google. You are seeing this in German because Google believes your preferred language is German.
This is usually determined by one or more of the following factors:
Google Account Settings: If you are logged into a Google account, the default language for your account is likely set to German.
Browser Settings: Your web browser’s language preferences might be set to German.
Geolocation: Google may be detecting your IP address (or the IP address of your VPN/proxy) as being located in a German-speaking country (like Germany, Austria, or Switzerland), and is automatically localizing the interface for you.
To fix this, you can change the language settings on your Google Search page or in your Google Account preferences.
Edit: Neither my browser settings nor my Google account settings are set to German, and I’m not in Germany, so I don’t know why this search link is showing German.
