Cannot play MJPG encoded AVI file

[lapsed_time]

I'm taking timelapse photo recordings with a specialty camera. When I try to play the media back in VLC or WMP, the screen stutters in black frames for the extent of the recording, but no media is played. Media information via VLC shows that the video codec is MJPG, and the file ending is AVI (see below). If I convert this video with Handbrake to MP4, I can play it, but I'd rather not have to take that step. Can anyone help? Thank you.

Title: DSCF0002.AVI
Codec: Motion JPEG Video (MJPG)
Type: Video
Video resolution: 6480x4860
Buffer dimensions: 6480x4864
Frame rate: 10
Decoded format: Planar 4:2:2 YUV full scale
Orientation: Top left
Color space: ITU-R BT.601 Range
Chroma location: Center

EDIT - UPDATE: I was able to play the video with ffmpeg. I assumed that it would be playable with VLC as well because it has the decoder for MJPG, but I must be missing something.

Please open Tools -> Messages (set Verbosity to 2) before you start the playback, keep the messages window open during the whole process and then paste the full resulting log here or on Pastebin.com or on Justpaste.it if it's too long.

Also upload a short sample of your original problematic file to WeTransfer.com or Disroot.org and then post the link to the file here.

Frame rate: 10

VLC has troubles for playing some low FPS videos, it's a known issue for a long time and still awaiting for a fix.
I've read it should be fixed later in VLC 4.

Thank you for responding to my post.

I logged the playback but it's so long that I had to make two Pastebin uploads. It looks like the log repeats the same information over and over throughout the clip with minor variations.

I don't know how to shorten my original problematic file, and the file itself is ~2 gigs. Can you advise on how to shorten to a reasonable but useful size for upload? Thank you again!

Looks like this video has a very large resolution, please upload a sample file as requested in my previous post.

I don't know how to cut the video into a small sample. Can you advise on software? Thank you again!

Cut it with DGsplit and read here about how to do it:
https://forum.videolan.org/viewtopic.ph ... 35#p193335

200 MB max should be enough but a full complete short file is better.

Perfect! Thank you.

If you end up needing a "full complete short file", please advise and I will provide. The file above is the first 200 mb chunk of the ~2 gig total file.

Yes, I can reproduce the issue while it's playing fine with some other players.
You should create a new report ticket on the VLC issues tracker with your above report, the links to your messages logs, the link to your sample file and the link to this thread:

If possible, because of this:
