MF_E_NET_PROTOCOL_DISABLED
MF_E_NET_PROTOCOL_DISABLED means the required network protocol was disabled in the source configuration. Media Foundation exposes separate enable flags for HTTP, RTSP, TCP, UDP, streaming, and download modes.
What to check
- Check the network-source properties set by the application before opening the URL.
- Enable only the protocol required by the expected media URL and transport.
- Verify that a policy or wrapper component is not overriding the application configuration.
