The current _gl_memory_upload_transform_caps() only simply apply "memory:GLMemory" to all input caps to transform the output caps. This is not precise and may cause problem. For example, if the input caps include: video/x-raw(memory:DMABuf), width=(int)1920, height=(int)1080, \ interlace-mode=(string)progressive, multiview-mode=(string)mono, \ framerate=(fraction)30/1, drm-format=(string)NV12:0x0100000000000002 it will be changed as video/x-raw(memory:GLMemory), width=(int)1920, height=(int)1080, \ interlace-mode=(string)progressive, multiview-mode=(string)mono, \ framerate=(fraction)30/1, drm-format=(string)NV12:0x0100000000000002 For GLMemory kind caps, no drm-format should appear. So we should let it only transforms which it can recognize. And in _gl_memory_upload_propose_allocation(), we should only allocate the allocator and buffer pool for the caps with "memory:GLMemory" feature.
