[Libav-user] 920523 - does ffmpeg support 4HKH?

[hamidi]

hi
Hikvision company offers a DVR Card (DS-4016HCI). when i get stream and
dump it to a file i see that the first four characters are 4HKH. the format
seems weird. i could find a filter for Windows Media Player to play it. so
it's a video file anyway. but ffmpeg can't understand it. i could not play
it by ffplay. it doesn't recognize it. also vlc can't play it. i tried to
set the card to change the format to something familiar, but i couldn't
find a way. so, i thought about helping ffmpeg to recognize it. but i have
no idea how it may be possible.
any help/clue appreciated.
