Function FREMediaBufferUnlock 

pub unsafe extern "C" fn FREMediaBufferUnlock(
    ctx: FREContext,
    mediaBuffer: FREObject,
    bUpdate: u32,
) -> FREResult

Unlocks a MediaBuffer bitmap.

Currently the bUpdate parameter is ignored: changes to the data provided by the FREMediaBufferLock function will always have an impact on the rendered bitmap. This parameter is provided to allow for future flexibility.

Parameters

• ctx: The FREContext for the native extension instance.
• mediaBuffer: The AS3 MediaBuffer object for which the image data is released.
• bUpdate: Whether to use the updated data for rendering. Note that this parameter may not have any effect.

Returns

• FREResult::FRE_OK
• FREResult::FRE_INVALID_ARGUMENT If the ctx or mediaBuffer parameter is null.
• FREResult::FRE_INVALID_OBJECT If the MediaBuffer object has an incorrect type.
• FREResult::FRE_WRONG_THREAD If called from the wrong thread; at some point this function will be updated to allow multi-thread calling.
