Crash in -[GVRVideoTextureGenerator renderTexturesIfAvailable:]

[berendo]

I am encountering a persistent crash in -[GVRVideoTextureGenerator renderTexturesIfAvailable:] while playing back some videos. Here's what the backtrace looks like:

Here are the pieces of information I have distilled so far:

• The crash occurs in both version 1.30 and 1.10 (I have not tried any other versions).
• The crash occurs on an actual device (tested on an iPhone 7 Plus), but does not occur in the iPhone Simulator.
• The crash does not occur with every video, but only some videos (here's a link to a video that exhibits this crash: https://s3-us-west-1.amazonaws.com/media-nc.eyefi.com/videos/2238371611/f82fe1404305b28f60912ce3a73e57c2e3ac9a82/480/movie.mp4).

Can you give GVRKit video renderer a try: https://github.com/googlevr/gvr-ios-sdk/blob/master/Samples/GVRKit/GVRVideoRenderer.h ? It is provided as sample code, so you can easily debug the issue.

This is also released as GVRKit cocoapod. See the updated VideoWidgetDemo sample. GVRVideoView will be deprecated in a future release.

Closing the issue. Feel free to re-open if you need to.
