VTDecompressionSession.DecodeFrame and NewDecompressionCallback #17394
Description
When calling a VTDecompressionSession.DecodeFrame in Visual Studio for Mac 17.4.3 with wrong buffer data for decoder, the Callback not called and application crashed.
Steps to Reproduce
// callback
private void OutputCallback(IntPtr sourceFrame,
VTStatus status,
VTDecodeInfoFlags vtDecodeInfoFlags,
CVImageBuffer buffer,
CMTime presentationTimestamp,
CMTime presentationDuration)
{
}
// create session
_decSession = VTDecompressionSession.Create(OutputCallback,
_formatDescription,
videoDecoderSpecification,
destinationImageBufferAttributes);
// decode frame
var decodeStatus = _decSession.DecodeFrame(sampleBuffer, VTDecodeFrameFlags.EnableAsynchronousDecompression, IntPtr.Zero, out VTDecodeInfoFlags infoFlags);Expected Behavior
The Callback is called and provide null in CVImageBuffer buffer and provide error in VTStatus status if possible
Actual Behavior
The Callback not called and application crashed with exception:
