Try to play video with attached application. Audio is played but video is not shown. Error is printed:

Failed to find shader ":/qtmultimediaquicktools/shaders/rgbvideo.vert"
Failed to find shader ":/qtmultimediaquicktools/shaders/rgbvideo.frag"
QOpenGLShader::link: "ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
shader compilation failed:
"ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
QOpenGLShader::link: "ERROR: Compiled vertex shader was corrupt.\nERROR: Compiled fragment shader was corrupt.\n"
QOpenGLShaderProgram::uniformLocation( qt_Matrix ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( rgbTexture ): shader program is not linked
QOpenGLShaderProgram::uniformLocation( opacity ): shader program is not linked

workaround is to add Q_INIT_RESOURCE(qtmultimediaquicktools); to main() function.
