I’m logging some pretty big videos in tables (each 20-80MB) with about 50 rows with such videos. When I’m looking through these on the run dashboard, they sometimes go blank with an error message: pipeline\_ERROR\_READ: FFmpegDemuxer: data source error

I’m saving the videos locally first as a webm and then wrapping the wandb video object with the filepath name to the constructor and logging the video to a row in a table.

Is this a filesize issue as I’m guessing? Or something else? How would I attempt to fix this issue if not a filesize related issue?

Thanks!

Hi @serialexperimentsleo, sorry you are running in to this. Could you send a link to the workspace where this is happening and I can take a look?

Thank you,  
Nate

Thank you for the response! If it’s a private project, is there a way I can still send you the workspace/run? In the meantime, I can send you a [public report](https://wandb.ai/contact-estimation/contact_estimation/reports/Untitled-Report--VmlldzozNzc4MjY1?accessToken=fuyedmxqm9q1ymdhnp90xlm3ps0gsg1d77xrz2svyjrqpt3cgt5b0etjlant91gy) with the table of large videos where I still get the issue. The error message doesn’t appear immediately, only after the videos have autoplayed for a minute or so which is the annoying part… I assumed at first it was a timeout due to video not being loaded quickly enough, but now im not so sure…

Hi @serialexperimentsleo, I see the issue. Unfortunately, I’ll have to have our app team look into it to get a fix on this. I can follow up as soon as we are able to get a fix.

Thank you,  
Nate
