MF_E_SINK_HEADERS_NOT_FOUND
MF_E_SINK_HEADERS_NOT_FOUND indicates missing format-specific header information at the output sink. The sink may have received samples, but it cannot author a valid file because required codec configuration or stream description data was never supplied.
Inspect media-type headers before finalization
- Log the final media type on every stream sink, including binary attributes such as sequence headers or codec user data.
- For H.264 MP4 output, verify that SPS/PPS information is available through the sequence-header or supported passthrough path.
- For AAC and other formats, preserve the codec-specific configuration used to build the sink media type.
The MPEG-4 file sink documents that some sample-description information must be present in the media type and that certain data can be updated before finalization. Writing more ordinary samples does not necessarily supply missing headers. Compare the final stream media type with a known-good encoder output.
