| * vaapijpegdec decodes a JPEG image to surfaces suitable for the | |
| * vaapisink or vaapipostproc elements using the installed | |
| * [VA-API](https://wiki.freedesktop.org/www/Software/vaapi/) 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. | |
