Thanks Peter for your response.

When i received the axis h.264 frames, i pass it to directshow using the Microsoft DVD-DTV filter and this filter can decode the frames, so i guest the axis H.264 is OK.

is the stream output from the encoder processed correctly by other stream analysis tools such as Elecard StreamEye?
- Well i don't know Elecard StreamEye, tomorrow i will take a look on it.

So, when you feed leading stream data into DecodeHeader() it always returns "-10"?
- Yes

SEI message(s) are not required to decode the stream header or to decode the stream frames.
- Well the Microsoft decoder need it because without it the output was garble.

In any case, if you can, please provide a pure stream dump from the device so that we can investigate it from our side.
- i will do that tomorrow

Thanks for your time.

The Elecard StreamEye work fine, it decode the video.

can someone explain to me how to send a file ? i select Add Files, but how to make it available to this post ?

Thanks

Soupalognon.

Yes i found how to attach a file :-)

This file is a few seconds samples from my Axis camera.

this is exactly the same data that I send to Intel decoder.

small update:

So, when you feed leading stream data into DecodeHeader() it always returns "-10"?
- The decode Header is OK, the problem is when i use DecodeFrameAsync.

Here what i do exactly

1) Initialize MFXVideoSession with version 3,1
2) Call QueryIMPL to determine if Hard of Soft decoding
3) Call the DecodeHeader for each frame until no error is returned
4) Call decoder->Init
5) Allocate surface

When the header is decoded
6) Get a free surface
7) call DecodeFrameAsync (always return -10)

this is where i'm trying to fix.

thanks

Petter thank you, I will look at the example and try to make it work.

thanks for your time.
