Can't generate preview images from a YouTube stream

[mithro]

Need a gstreamer / mplayer / something else to create preview images.

The YouTube Data API appears to have "thumbnail" functionality built in. At present, it appears to show the channel preview card which is configured when the camera ingestion is configured.

It's not clear why this doesn't have an actual preview image, but it may be something to follow up with YouTube if this behaviour is intentional.

Further info is in the API documentation.

Preview images for YouTube streams can now be generated (8a0d381b). Might need to revisit that to allow generation of preview images for both YouTube and flumotion.

Might be good to document what gstreamer features are needed for that script I wrote. I think you need a recent libsoup and gstreamer....

hi @micolous, I was trying to get the Youtube thumbnails with the sqp information， and I did the Youtube Api on "liveBroadcasts" like yours。However, I can not get the same result as yours，Do you have any ideas?

[micolous]

I'd suggest following up on YouTube's GitHub repos if you're having trouble with the API... this isn't a YouTube support forum.
