Crash with Multiple Concurrent MFX Encoder/Decoder Sessions #189
Description
We are experiencing crashes when running multiple simultaneous MFX encoding and decoding sessions. The crash occurs randomly during concurrent operations with different resolution streams.
I'm uncertain whether this is caused by incorrect usage on my part or if it's genuinely a driver bug.
Could you provide some insights based on the stack trace? The crash details might help identify whether this is an API usage issue or a deeper system-level problem.
