using video memory returning MFX_ERR_MEMORY_ALLOC


Hi all,

I'm using a endoder/decoder and when the allocator is going to  perform the memory allocation 

status = mfxAllocator.Alloc(mfxAllocator.pthis, &_encRequest, &mfxEncResponse);


I'm using video memory in hardware mode.

In the decoder part there is no problem I have this problem only in the encoder. is there any reason for that errror? I think that there is enough memory.

Hi Fernando,

The information in your thread is not enough to understand why you are seeing the error. Can you let us know the following:

- Platform details (OS, hardware, version of MSS. If Windows, can you print output of system analyzer found in <SDK>/tools/sys_analyzer)

- Can you use our tutorial application simple_3_encode_vmem or simple_3_encode_vmem_async  ( to see if you observe the same issue? These are code examples that are doing video encode using video memory and HW implementation.

- Can you send the command-line you are using (what codec, params being given)?

Here is the information...

Yes, I have test that examples and they works, but the problem is that I'm creating several encoders/decoders. with decoders there are no problems, but with encoders if I create one it is OK but when I create a second one alloc returns the error.
