// Filter GUID
// {99709313-5825-42ab-82ED-A7AD88ACBF4A}
DEFINE_GUID(CLSID_NANO_RTSP_SOURCE, 0x99709313, 0x5825, 0x42ab, 0x82, 0xed, 0xa7, 0xad, 0x88, 0xac, 0xbf, 0x4a);

Buffer statistics can be retrieved using IRTSPSourceBufferStats interface.

// IRTSPSourceBufferStats interface
// {655D499B-C9E0-4134-9DC4-6431FEEB5EB0}
DEFINE_GUID(IID_IRTSPSourceBufferStats, 0x655d499b, 0xc9e0, 0x4134, 0x9d, 0xc4, 0x64, 0x31, 0xfe, 0xeb, 0x5e, 0xb0);

Use standard DirectShow interface ICodecAPI to get/set these parameters:

// ICodecAPI GUID
// get/set receive timeout in seconds
// VARIANT_TYPE: VT_I4, VARIANT::intVal
// default value: 2
// {33759D2A-3B7D-45ac-A8BF-C2477915C03B}
