>> Currently you cannot just use any shader you grab off the internet in glshader. If the shader is ill-formed (syntax errors, etc) then we will be unable to use it and glshader will error out appropriately (perhaps with the obscure error). You can see some debug information by setting GST_DEBUG=3 or GST_DEBUG=gl*:7 for everything GL related about why it failed to initialize and what it was trying to do.<br>
