The VideoLAN Forums

I recorded videos using a Raspberry PI as a surveillance camera with 1 fps and motion detection.
The video is stored as MKV in seperate files (one file per motion, i.e. sequence of consecutive frames with differences).

When I transfer the files to Windows 10 I can't watch them using VLC.
VLC opens the file and displays only the first frame; the time line ticks away every second of the video, but the video never changes.
The messages window shows:

avcodec info: Using D3D11VA (Intel(R) UHD Graphics, vendor 8086(Intel), device 9b41, revision 2) for hardware decoding
main error: buffer deadlock prevented
avcodec error: more than 5 seconds of late video -> dropping frame (computer too slow ?)

The last line is repeated several times.

The computer is surely not too slow to play a 1 fps video.
Windows Media Player can play the file, but it can't skip or change playback speed.

That's the frame drop algorithm going in because next frame is considered late.

you can try playing with hurry-up parameter in avcodec.

VLC can't play low fps movies since the beginning.
