> FFMPEG gives error of 1 when trying to extract image files from VGA feed
> ------------------------------------------------------------------------
>
> Key: MH-8272
> URL: http://opencast.jira.com/browse/MH-8272
> Project: Matterhorn Project
> Issue Type: Task
> Components: Architecture & Services
> Affects Versions: 1.2, 1.3
> Reporter: Christopher Brooks
> Assignee: Tobias Wunden
> Priority: Release Blocker
> Fix For: 1.2.1, 1.3
>
>
> Sometimes, VGA video that is captured from the capture agent fails to
> segment. FFMPEG fails to extract segments in particular, here's a command
> that we have failing:
> ffmpeg -strict inofficial -y -i
> /data2/opencast/workspace/mediapackage/3c995799-7220-4d95-b1c1-14310a2e428a/af97fe33-8d91-4166-ab47-fd4022c8eece/vga.mpg
> -ss 2435 -r 1 -vframes 1 -f image2 -pix_fmt rgb24
> /data2/opencast/workspace/mediapackage/3c995799-7220-4d95-b1c1-14310a2e428a/af97fe33-8d91-4166-ab47-fd4022c8eece/vga_2435_7aabe258-39c7-43ae-9fe6-5cd943b2788a.2435.jpeg
>
> This has happened with media from various capture agents, and does not seem
> deterministic. Once media has a problem, it is 100% reproducable with that
> media. The problem is with ffmpeg.
> Potential work around: change the default workflow to not fail on error.
> Then lectures should process, albeit not completely correctly since they
> won't be segmented *sometimes*. This is being tested on U of S test stack.
> Other workaround: reencoding the media to mkv (default settings) then
> reprocessing the media makes this problem go away (segmentation is
> successful).
> Open issue: Unclear whether newer ffmpeg solves this issue.
> Waiting on local team to make media available for further testing.
