Could you please write this helper in GStreamerCommon.h? GstMappedBuffer(const GRefPtr<GstBuffer>& buffer, GstMapFlags flags) : GstMappedBuffer(buffer.get(), flags) { } Then you don't have to pass buffer.get(). More bonus points! I see it would be interesting to also write an ASSERT(GST_IS_BUFFER(m_buffer)); at: ~GstMappedBuffer() { if (m_isValid) { ASSERT(GST_IS_BUFFER(m_buffer)); gst_buffer_unmap(m_buffer, &m_info); } m_isValid = false; }

There are g_checks but for us it is safer to have ASSERT.
