How to calculate sampleTime and sampleDuration before decode
I have create ogg decoder in media foundation
I have read some packte as a sample (compress data), now I need to know the sample' time and sample's duration
Now I know the AvgBytesPerSec and SamplesPerSec and so on, but this parameters are use for uncompress data
so how can get IMFSample's time and duration by use compress data ?
