hi guys,
when I use tidec_decode tool to decode my own H264 file, its output is just like below. I want to know what is the meaning of the prompt "unclassified data detected!"
The H264 file is normal and can be played using other system software. So, how this happens and is there anything wrong? Thanks for your help.
