Open your avi in avicodec to see the real videocodec.

Upload the AVI to a file hosting service and post the download link here.

Security cameras often try to disguise the fact that they use open source codecs by changing the fourcc code. Try using AVI Fourcc Code Changer to change the codec to XVID.

Tested with all possible fourcc codes.
No result. Does the security camera have a player that can play the file?
In this case, you could copy the video using screen recording software.
pyv5 could be a proprietary codec; in this case you're out of luck.

thats the point,i dont know what camera or software did it,so its all about luck to find some guy who heard about PYV5,If I had camera or player,any lead,I wouldnt be here

It seems to be related to H263. Using 'ffplay -vcodec h263' to play to the file is giving some different shades of grey that change over time. So not perfect yet, but a step in the right direction.

yeah grey black screen,its only loud i guess it can't help,thanks anyway

most likely pyv5 is not a codec, but some fourcc the security camera put instead of some normal one for AVC or HEVC.

What would i do is to dump a video stream only, and try feed it ot some video analyser so it can try to recogzise it.

thank you so much, actually i found some guy from 2018,Russia, same problem as me and no answer, but there was "yvf5" codec my brain think its 100% 1 codec or 1 videocamera idk,but no anwser for 10~ years its amazing, here is the link: https://forum.ixbt.com/topic.cgi?id=29:36483

Hi !
I know that some security cameras which create AVI video files oftently use MJPEG codec.
Try to make a backup of your video file and change the FourCC to MJPG instead of PYV5 and open it with VLC.
Best regards
