One of the few apps that could play me a video in MKV with the difference that the audio via Bluetooth was accurate and on top of that at a higher volume level than other apps, I also found that it is one of the few that asks about the permission of access external devices such as Bluetooth headphones, I think that helps the sound through these to be fluid and the video codecs can reproduce it well. I've tried other apps and they didn't open the video or they opened it but the sound couldn't be heard or it stuttered. Infuse has very good codecs and is well updated, so it handles me fluently. Not to mention that the minimized player option is quite useful tmb…! Highly recommended, I have been using it for years and they are still great!
