Android: Can't set H264 decoder
Posted: Thu Jun 06, 2019 11:51 pm
I'm having real problems getting the stereopi to make and maintain a wifi connection. (I don't know if this is a factor, but my wifi system is a pi3 running a wireless bridge - this has the advantage that I can tcpdump all the traffic to any device, which isn't possible with an off-the-shelf NAT wifi router, which hides the real IP addresses from the main router)
What is making it especially difficult is that it is impossible to do a console login to see what the problem is and fix things, and of course when the wifi is broken you can't log in over wifi.
(It would be really helpful if you could press alt-f2 to bring up a second console with a login prompt.)
Whenever I start the cell phone android app, I see a message for a short time that says "Can't set H264 decoder". Then I either get a black screen, or the white screen with the two raspberries and a cycling indicator that it is still trying to contact the stereopi. I haven't managed to get any video anywhere other than on the stereopi console yet.
At one point I had both my stereopi and my cell phone online, but as soon as the cellphone tried to contact the stereopi, the stereopi would repeatedly put out arp requests for the phone (Galaxy-J3-Prime) which were never answered. I finally inserted a manual arp entry so the stereopi could ping the cellphone but there was still no connectivity in the app. netstat -na has *never* shown a connection of any kind from the stereopi to the cellphone.
