[Mp4-tech] Question about MPEG-4 BIFS

[Ik-Hwan Cho]

Dear all experts, 
I hope someone lets me know if I can change some pixel value of decoded
video frame using BIFS command for display(not real reference frame).
Actually, I’ve known that BIFS is used to composite multiple data stream
in same mp4 file and it supports a lot of tools(it is called ‘node’) for
visual editing and manipulation.
But I think if we can get and change pixel values by using BIFS command,
then we can make more richer composition in rendering moment.
If there are someone who have an ideas, please answer me..
For any idea and knowledge, I will appreciate for that.
Thanks for reading my question.
Best regards, 
Ik-Hwan Cho
