Firmware 1.13.0-beta6 Crash: video:getContext() is broken

SDK Bug Reports
1

Since my playdate was updated to 1.13.0-beta6, the following sample code print nil for the video context

basePath = "levels/LEVEL01"
print("Loading video", basePath)
video, errorMsg = playdate.graphics.video.new(basePath)
frameCount = video:getFrameCount()
print("error is", errorMsg, "frameCount is ", frameCount, "context is", video:getContext())

Loading video levels/LEVEL01
error is nil frameCount is 114 context is nil

The sample video has pretty small dimensions of 164x64, but the same happens with a 400x240 video.
This worked fine on hardware with firmware 1.12.3 and also the current 1.12.3 simulator:

Loading video levels/LEVEL01
error is nil frameCount is 114 context is playdate.graphics.image: 0x7fa2e2064398

oh, yep, I think I see what's happening. I changed from using a hacked-together reference system to lua_setiuservalue(). getContext() lazily creates the context, and in that code change I forgot to add a duplicate of the image object for returning. It should work as expected if you call video:getContext() a second time.

Thanks for catching that!

Can confirm this workaround works; I almost tried this myself after reading in the documentation that the context would be created upon first call to this function

Silly question but where do we find this beta SDK/Firmware?

I've asked if there was a beta program in the past, so I could test toybox.py against future versions of the SDK, but never got an answer... :slightly_frowning_face:

It may be based on playdate serial number. My playdate is a "developer preview" unit from before mass production
