[tvOS] VLCOpenGLES2VideoView.doResetBuffers: modifies layer off main thread

[jmhunter83]

Description

On tvOS, VLC's internal VLCOpenGLES2VideoView triggers UIKit threading violations when resetting buffers. This happens because doResetBuffers: modifies CALayer properties from a VLC background thread.

Error Message

Modifying properties of a view's layer off the main thread is not allowed: 
view <VLCOpenGLES2VideoView: 0x...> with nearest ancestor view controller <...>

Stack Trace

0   UIKitCore    ...

7   TVVLCKit     -[VLCOpenGLES2VideoView doResetBuffers:] + 164
8   libsystem_pthread.dylib   thread_start + 8

Environment

• tvOS 18
• VLCUI 0.7.4
• TVVLCKit (from VLCUI dependency)

Workaround

Wrapping onSecondsUpdated and onStateUpdated callbacks with Task { @MainActor in } addresses our callback code, but the internal doResetBuffers: issue requires a fix in TVVLCKit or VLCUI.

Related

This may need to be reported upstream to the TVVLCKit project if it's not solvable at the VLCUI layer.
