Description
In evrd3dpresentengine.cpp :
QVariant IMFSampleVideoBuffer::handle() const { QVariant handle; #ifdef MAYBE_ANGLE if (handleType() != GLTextureHandle) return handle; if (m_textureUpdated || m_engine->updateTexture(m_surface)) { m_textureUpdated = true; handle = QVariant::fromValue<unsigned int>(m_engine->m_glResources->glTexture()); } #endif return handle; }
At some point the m_glResources of m_engine is nullptr.
Here's the relevant part of the backtrace :
