What is Reddit's opinion of BubbleUPnP UPnP/DLNA License?

From 3.5 billion Reddit comments

There is an app you can get called BubbleUPnP so you can stream it using your phone. Here is a nice tutorial. Only downside it that it costs a few bucks, but is well worth it.

Edit Linked to the wrong tutorial

I use Bubble UPnP and it works great.
It doesn't require root or anything and can stream music and video to Xbox.

If you want to do WiFi streaming, install $3.50 BubbleUPnP on the phone and use the Windows 10 built-in DLNA streaming. If you're on Ubuntu you can install pulseaudio-dlna and use it as output from sound settings. I'm sure there's something for Mac as well.

For USB, what you're looking for is called a USB DAC. If you're really strapped for cash and don't have fancy tastes in sound quality, or quality headphones, then one of these $5-7 puppies will take care of it. Quality is touch and go, some may be DOA and need replacing, but they'll get the job done. You can also go for a $20 Signstek (PCM2704), but I wouldn't recommend more expensive ones without knowing what headphones you're using and what you want from them.

If you do, I can recommend the $40 FiiO K1, $65 SMSL SD793-II or $75 FiiO E10K, but if you do that you should also look into putting $50-200 into decent headphones and you're probably not looking for that.

Whatever you do DO NOT get USB headphones. Decent ones are expensive, cheap ones are absolute crap. A $5 DAC like above and a $25 pair of Sennheiser HD202 will be better and can be replaced separately or even taken apart and repaired if they break.

So far, I haven't been able to screen mirror. If you're running into the same problem with casting that I was ( where the Fire TV wasn't appearing as a castable option) I remedied this by purchasing and downloading licensed apps that allowed the connection. I have the link below. Bubble UPnP with licences https://play.google.com/store/apps/details?id=com.bubblesoft.android.bubbleupnp.unlocker https://play.google.com/store/apps/details?id=com.bubblesoft.android.bubbleupnp

All Screen and AllCast are both decent free apps with a wide variety of connectivity options that I use for casting sites like Putlockers and 123 movies https://play.google.com/store/apps/details?id=com.toxic.apps.chrome https://play.google.com/store/apps/details?id=com.koushikdutta.cast

Cast to TV by InShot are two separate apps made by the same developer four different specific casting options. These are also free. https://play.google.com/store/apps/details?id=castwebbrowsertotv.castwebvideo.webvideocaster https://play.google.com/store/apps/details?id=cast.video.screenmirroring.casttotv

But all in all, no I haven't figured out the screen mirroring yet 😭.

BubbleUPnP > Windows Media Player works for me.
