In the documentation for MFXMuxer_PutBitstream, for bs it says:
bs - Pointer to the input bitstream. The Data, DataLength, FrameType (MFX_FRAMETYPE_I or not) and DecodeTimeStamp fields are mandatory. Use MFX_TIMESTAMP_UNKNOWN if TimeStamp is unknown.
Can DecodeTimeStamp field be set to MFX_TIMESTAMP_UNKNOWN ?
How do I know what value to use for FrameType?
And which of this are values set by me vs automatically by EncodeFrameAsync?
Thank you!

Figured it out, when calling MFXMuxer_PutBitstream(mfxMuxer mux, mfxU32 track_num , mfxBitstream *bs, mfxU64 duration)
I used track_num = 0, only it turns out tracks are 1 instead of 0 indexed, so I had to switch this:
MFXMuxer_PutBitstream(*muxer,0, h264Bitstream,0)
to this:
MFXMuxer_PutBitstream(*muxer,1, h264Bitstream,0)

Also, little bit more information, the values that I see for these with h264Bitstream in MFXMuxer_PutBitstream(*muxer,0, h264Bitstream,0) are:
Data: Non-null pointer
DataLength: 24036
FrameType: 193
DecodeTimeStamp: -3000
TimeStamp: 0
However if I set TimeStamp and DecodeTimestamp both to MFX_TIMESTAMP_UNKNOWN before passing them into MFXMuxer_PutBitstream , I get:
DecodeTimeStamp: -1
TimeStamp: 18446744073709551615
Why are those two different? Is TimeStamp being set to the current system time maybe?
