qmlglsink dummy black texture patch (3.49 KB, patch)

Description Carlos Rafael Giani 2017-05-21 13:33:50 UTC 
Currently, the GstQSGTexture bind() function doesn't really do anything if a null GstBuffer pointer is supplied. This results in some random pixels being shown, because an invalid texture is used in the QSGNode. Fix this by binding an internal dummy black 64x64 RGBA texture if the GstBuffer pointer is NULL.
