[Bug]: D3DTexture2D import encode crashing with MFX_ERR_LOCK_MEMORY

[ma3uk]

Which component impacted?

Encode

Is it regression? Good in old configuration?

None

What happened?

OS: Windows 11 23 H2
Video driver: gfx_win_101.5330, gfx_win_101.5194, gfx_win_101.5186
Video card: Arc A380

I am developing a plugin for OBS Studio using libvpl for real-time coding. With the release of libvpl 2.10, textures for encoding were added and supported, it works, but I ran into a problem, after a few minutes the encoding process was interrupted with the error MFX_ERR_LOCK_MEMORY from the EncodeFrameAsync function. Further attempts to start encoding are immediately interrupted with the MFX_ERR_LOCK_MEMORY error until the application is restarted.

A step-by-step process that I'm doing:

1. A pool of intermediate textures is being created
2. Copying an external texture to pool
3. Importing textures from a pool to libvpl
4. Encode
   The error occurs at stage 4. There are no errors in the first 3 stages

The source code of the application can be found at the links below:

• The function of allocating a pool of intermediate textures - https://github.com/ma3uk/obs-qsv-onevpl/blob/edf5864eec4a3965dc660e48b4641bd9404daa7f/obs-qsvonevpl/obs-qsv-onevpl-encoder-internal.cpp#L1266

• The internal function of texture allocation - https://github.com/ma3uk/obs-qsv-onevpl/blob/edf5864eec4a3965dc660e48b4641bd9404daa7f/obs-qsvonevpl/helpers/common_directx11.cpp#L131

• The function of copying an external texture to a texture pool - https://github.com/ma3uk/obs-qsv-onevpl/blob/edf5864eec4a3965dc660e48b4641bd9404daa7f/obs-qsvonevpl/helpers/common_directx11.cpp#L273

• The function of importing textures into libvpl and encoding - https://github.com/ma3uk/obs-qsv-onevpl/blob/edf5864eec4a3965dc660e48b4641bd9404daa7f/obs-qsvonevpl/obs-qsv-onevpl-encoder-internal.cpp#L1607

It is also worth clarifying that in my case the error occurs when encoding the 65537 frame.
