No Video on MediaTek Device (Samsung Galaxy A15)? #6

Open defrag-bambino opened 1 month ago

defrag-bambino commented 1 month ago

Hi, I just tried out the WifiLink by RunCam. Using the FPV4Win Windows App I receive the video just fine. However, using the same External Wifi Module (the one that comes with the WifiLink-G version), the PixelPilot app does not display any stream. I did use the correct gs.key, generated by the WifiLink board. I also tried switching to h264. I am on the correct channel 173 with both devices. The PixelPilot App just says "Starting wfb-ng on channel 173 ..." - but never displays anything.

I am using a Samsung Galaxy A15 (not 5G version), which is a pretty new phone (2024) with the latest Android version. It has a Mediatek Helio G99 processor, which seems to be capable of both h264 and h265 - so it should be capable of handling this use-case just fine.

Any ideas what may be going on here? Is there any possibility to get a logfile from the PixelPilot App?

This is a common issue with MediaTek SoCs as the third party encoder used the this app primarily supports snapdragon processors. Logs would be useful for debugging this issue

For obtaining logs, once #3 is merged there will be a share button. But for now the only way to obtain logs is using logcat on a PC

Could you upload an .apk build of #3 while we wait?

Nothing jumps out straight away, another useful bit of information for debbuging would be the details of the HEVC decoder from https://play.google.com/store/apps/details?id=com.parseus.codecinfo

What is the "third party encoder" used? May I open an issue in their github to get this fixed?
