IMFSourceReader.ReadSample never hitting callback after reading on stream index 1. Calls to Stream index 0 work fine.

So background im working on reworking an application that was using direct show to use Windows Media Foundation. in Directshow i have UVC camera still pins working fine. however when i switched to using a SourceReader in WMF i have stream 0 (the live video stream) however when i use the same interface to try and request samples on Stream1 i dont receive anything. This is with the following call.
                    hr = StreamReader.ReadSample(1,
                            MediaFoundation.ReadWrite.MF_SOURCE_READER_CONTROL_FLAG.None,
                            IntPtr.Zero,
                            IntPtr.Zero,
                            IntPtr.Zero,
                            IntPtr.Zero
                            );

if i switch it to 

                    hr = StreamReader.ReadSample(1,
                            MediaFoundation.ReadWrite.MF_SOURCE_READER_CONTROL_FLAG.Drain,
                            IntPtr.Zero,
                            IntPtr.Zero,
                            IntPtr.Zero,
                            IntPtr.Zero
                            );

i receive only null IMFSamples. ive checked the state of hr and it is always S_OK. During this time i am also running the same call but on stream 0 and it is working fine. The only error or flag i get is StreamTick on the first frame on stream 0.

Im not entirely sure where to go from here if anyone has suggestions im open
