Media SDK decoder fails to decode h264 video with motion_vectors_over_pic_boundaries_flag

As described in subject field, the h264 feed, that has motion_vectors_over_pic_boundaries_flag set to 1 in sps header sequence is decoded to huge artefacted green screen. Both in my project and provided decode_sample example.

Feed used is received from Microsoft Media Foundation encoder on WIndows 8 and 10 or from ffmpeg with default 264 presets.

All the returns are MFX_ERR_NONE and no warnings are being received throughout initialization, header decoding and frame decoding processes.

Hi Danil,

Could you please provide encoded stream to reproduce the problem? Is it decoded well by other decoders (ffmpeg)?

Best wishes,

Anna

Greeetings, Anna.

Encoded feed could be found here: cdn.livestream.com/LivestreamStudio/Intel/media_foundation_feed.264

VSoft decoder seems to do it just fine. Also, Media Player Classic is able to play this file as is.

This data are encoded by Media Foundation encoder on Windows 8.1 Pro.

Looking forward to your responce.
