vaapijpegdec
vaapijpegdec decodes a JPEG image to surfaces suitable for the vaapisink or vaapipostproc elements using the installed VA-API back-end.
In the case of OpenGL based elements, the buffers have the GstVideoGLTextureUploadMeta meta, which efficiently copies the content of the VA-API surface into a GL texture.
Also it can deliver normal video buffers that can be rendered or processed by other elements, but the performance would be rather bad.
Example launch line
 gst-launch-1.0 filesrc location=~/image.jpeg ! jpegparse ! vaapijpegdec ! imagefreeze ! vaapisink
