I have a video file that doesn't seem to play in Processing's glvideo library. (framebuffer errors, no display)
It has a MOV file extension rather than the MP4 I normally test with, but there is little (if any) difference when I compare the actual stream parameters in VLC. The only major difference that I see: For this file, the final, negotiated caps list "texture-target: rectangle", while normally I see "texture-target: 2D". Any idea what's going on?

If this is on OS X, then the zerocopy path with the VideoToolbox decoders will output textures with target=rectangle. That's just what VideoToolbox provides and you need to deal with that yourself or force a conversion with glcolorconvert ! texture-target=2D.

Thanks for your message, Matt!
My pipeline already has a glcolorconvert after the glupload, followed by a capsfilter element. But when I add "texture-target=2D" to the capsfilter, the final (negotiated) caps for the file still look like this: "video/x-raw(memory:GLMemory), format=(string)RGBA, width=(int)640, height=(int)359, interlace-mode=(string)progressive, pixel-aspect-ratio=(fraction)1/1, framerate=(fraction)5000/167, texture-target=(string)rectangle" Any ideas what to try? I've uploaded the pipeline plot [1][2] when attempting to play that particular file, as well as the file itself [3]. This is macOS w/ GStreamer 1.8.3.

Could you show a pipeline where you set texture-target=2D please? Does the file play with gst-play-1.0? (It does here on a mac (10.11.4) with 1.9.90).

Hi Matt, How embarrassing: I must have edited the wrong codepath when I first tried. Did it again and it all works now.
