After upgrading to the latest Blynk App on Android (version 2.27.13 on Mar 24, 2020) the video streaming widget stopped streaming mjpg video generated by mjpg-streamer.
After downgrading to version 2.27.12 everything works again, that’s how I know it’s is most probably not a streamer issue).
Here some technical details if you want to replicate:
Running latest blynk server on Rpi.
Widget affected is the video streamer.
The video source is a mjpg-streamer compiled based on this repo: https://github.com/meinside/rpi-mjpg-streamer running at 15 FPS 640x480
Version 2.27.12 works, 2.27.13 does not.
*** Please do not refer me to the Beta channel - the stock app updates should work ***
