glupload reports caps for raw GstVideoGLTextureUploadMeta but doesnt intersect SystemMemory

[pneves]

The following program has caps taken from glupload in the sink_caps. It can match VideoCompositionMeta but fails on  GstVideoGLTextureUploadMeta because of the memory:SystemMemory. If i take out the memory feature, the intersect works.

Is this normal behavious is the GstVideoGLTextureUploadMeta dependent on the memory type?

int main(int /*argc*/, char* /*argv*/[]) {
        gst_init(0, 0);
        GstCaps * sink_caps = gst_caps_from_string("video/x-raw(memory:GLMemory, meta:GstVideoOverlayComposition), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], texture-target=(string)2D; video/x-raw(memory:GLMemory), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], texture-target=(string)2D; video/x-raw(memory:GLMemory, meta:GstVideoOverlayComposition), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string)RGBA, texture-target=(string){ 2D, rectangle, external-oes }; video/x-raw(memory:GLMemory, meta:GstVideoOverlayComposition), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }, texture-target=(string){ 2D, rectangle, external-oes }; video/x-raw(memory:GLMemory), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string)RGBA, texture-target=(string){ 2D, rectangle, external-oes }; video/x-raw(memory:GLMemory), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }, texture-target=(string){ 2D, rectangle, external-oes }; video/x-raw(memory:GLMemory, meta:GstVideoOverlayComposition), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(memory:GLMemory), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(memory:GLMemory, meta:GstVideoOverlayComposition), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }; video/x-raw(memory:GLMemory), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }; video/x-raw(memory:EGLImage, meta:GstVideoOverlayComposition), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(memory:EGLImage), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(memory:SystemMemory, meta:GstVideoOverlayComposition), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw, format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(memory:SystemMemory, meta:GstVideoOverlayComposition), width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }; video/x-raw, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ], format=(string){ RGBA, RGB, RGBx, BGR, BGRx, BGRA, xRGB, xBGR, ARGB, ABGR, Y444, I420, YV12, Y42B, Y41B, NV12, NV21, YUY2, UYVY, AYUV, GRAY8, GRAY16_LE, GRAY16_BE, RGB16, BGR16 }; video/x-raw(meta:GstVideoGLTextureUploadMeta, meta:GstVideoOverlayComposition), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]; video/x-raw(meta:GstVideoGLTextureUploadMeta), format=(string)RGBA, width=(int)[ 1, 2147483647 ], height=(int)[ 1, 2147483647 ], framerate=(fraction)[ 0/1, 2147483647/1 ]");
