Video: Support rendering out a single frame, as JPEG/PNG

[jonnor]

Should seek to a specified frame. Probably might want to make that video_start_frame input. And probably should work when outputting video also. At which point probably should also add video_end_frame for completeness...

Sounds like slightly overlapping functionality with https://github.com/the-grid/iconographer ?

Another interesting thing would be to request a set of frames and get an animated gif containing those, kind of like how Google+ does video previews

[jonnor]

GIFs should generally die... For that usecase, extract frames as JPEG and it play forward with JS.

Or could output as mp4/webm, with a very low framerate. Problem is, you want to be able to control the timing in the UI, and not have to re-render everything if you change your mind about it.

@bergie this does zero smarts, just obeys client request. iconographer is for the smarts.

[bergie]

Fair point. So then implementing this feature (extracting given frame as jpeg) would already do the trick

[jonnor]

Yes, assuming the client knows how many frames long the video is :)
