[GStreamer] Video rendering support for Qualcomm decoder
https://bugs.webkit.org/show_bug.cgi?id=307151
Reviewed by Xabier Rodriguez-Calvar and Nikolas Zimmermann.
The buffers produced by the Qualcomm decoder contain a single GstMemory which
stores the
GBM FD pointing to the decoded frame. The frame format is YUV (NV12). As this
is stored
in a single memory the existing DMABuf/YUV layer buffers cannot be used for
rendering. So
we rely on the EXT_YUV_target OpenGL ES extension to convert it to a RGB
texture for
rendering.
Manually tested on a device shipping the Qualcomm GStreamer decoder.
