VFW_E_NOT_COMMITTED

VFW_E_NOT_COMMITTED is a DirectShow HRESULT. The allocator has been configured but is not committed for streaming. A call that needs a sample buffer, such as IMemAllocator::GetBuffer, cannot succeed until the allocator is committed.

What to check

Finish allocator property negotiation before calling Commit.
Commit the allocator during the connection activation sequence, not while the graph is already tearing down.
After a stop, flush or reconnection, verify that the allocator was recommitted before sample delivery resumes.

This is an ordering error in the allocator lifecycle, not a shortage of memory.
