[Video] Video Component to extract 1 frame every N seconds

[ShihChun-H]

Issue Description

Current State

• The Video Component minimum FPS is 1 (integer)

Why We Want to Change?

• For a use case like presentation in the video, I do not want to extract 1 frame every second but 1 frame every 10 seconds to save resources and reduce the number of images needed to feed into the next component.

Proposed Change

• Change FPS to accept fractional inputs i.e. 60, 30, 1, 1/2, 1/4, 1/30…

Hi, @ShihChun-H ! If @samir-advantech is not available or working on this, can I work on this?

[kuroxx]

Hey @samir-advantech, since this issue has not been worked on for over >5 days, I will now assign this issue to @Reckadon 🙏 Thank you for your contribution attempt!

[Reckadon]

hi @kuroxx, thanks for letting me contribute. I have managed to setup the project but am facing error while building the instill-core. It is related to influxdb dependency failed to start: container influxdb exited (1)

Hey @Reckadon, thanks for raising the issue!

I saw your message on Discord - hope it can be resolved after adjusting the Docker resources : https://www.instill.tech/docs/core/deployment#docker-resource-requirements

do we want to accept inputs like 10, 30, 1/5, 1/10 only or, are pure numbers fine? like- 10, 30, 0.2, 0.1, 0.5

accepting both numbers and fractional strings will require the type field in tasks.json to be any.

It seems good that we can support 1/5 or 0.2.

accepting both numbers and fractional strings will require the type field in tasks.json to be any.

Yes, please proceed this. Thanks for confirmation!

[Reckadon]

@chuang8511 but the main issue is can the type field be any, I think only specific types like number or string are supported

[chuang8511]

Oh, I did not notice it. Could you try to set it as string first?

[Reckadon]

Setting it as string causes an error when u pass in a pure number like 10 from the frontend. It's because the JSON parser treats it as a number and does not convert it to a number string (10 and not "10"). I think allowing only numbers (integers and floats) and not strings is the only feasible option for now. Let me know if I can do something to change the behaviour of the Parser.
