@v0l what standard does zapstream use for streaming?

[v0l]

NIP-53

Amethyst / Nostrudel / nostur support it

[alltheseas]

@v0l do the apps you listed support viewing zapstream/nip-53 feeds only, or streaming + viewing?

[v0l]

Viewing / Zapping / Commenting only afaik

[alltheseas]

Are there any other apps beyond zapstream that can stream NIP-53?

I don't know if it makes sense to have this giant table of unrelated clients.

what do you suggest?

[fiatjaf]

what do you suggest?

having only clients that matter.

[alltheseas]

updated to a table with respondees only. is this good for now?

Maybe I've misunderstood the . symbols you've used above (might be browser/system dependant, but I filled in what worked for me. :)

[alltheseas]

thank you @YawningGoat :pray: updated accordingly

@v0l wen streaming support in snort?? :smiley:

[fiatjaf]

This issue is tracking two completely independent things. NIP-53 livestream support is very different than just displaying HLS from a URL in a note. webm is yet another entirely different thing.

[alltheseas]

What do you think is a better approach?

[fiatjaf]

One issue for NIP-53 live video events, another for displaying webm, another for displaying HLS in notes.

But I would not try to track webm and HLS support in notes, these are not compatibility-critical issues, they are more like nice-to-have features of clients. Pushing all clients to add support for these things is an anti-pattern.

In fact the fact that Damus is uploading video as HLS is kinda breaking everything, I think it's better if a simpler video URL that everybody understands as the main URL in the note content, then use that imeta tag to have an optional HLS link -- so yes, I think we need a different issue to address that.

[alltheseas]

Specific to NIP-53, @tyiu is considering adding support to display nip-53 scheduled events on comingle, and potentially add a virtual event filter/toggle/ui element.

[alltheseas]

In fact the fact that Damus is uploading video as HLS is kinda breaking everything

@fiatjaf upload damus default is .mp4. Damus renders HLS posted by any nostr app. For reference, here is the add support for streaming HLS issue from last year: https://github.com/damus-io/damus/issues/798

[alltheseas]

One issue for NIP-53 live video events, another for displaying webm, another for displaying HLS in notes.

@fiatjaf what do you think about calling a new category of non-NIP feature tracker where HLS, webm could fit in: "not mandatory", "fyi", or "bonus points"

[alltheseas]

From the end user and streamer perspective the concept of "streaming" is involves more than NIP-53.

See https://njump.me/note1vkulcuqym2whk2jkltcumevkw9eypmv459vkpyvq9ctzw97unx6sgrgzcu

I think its useful context to have for the streamer persona. Maybe nostrability repo is not the best place for it.

Do yall know of a nostr for streamers resource?

this is not true, damus does no such thing.

I want to though. Video doesn't really load on low bandwidth connections without adaptive bitrate streaming, which every video and social media platform uses, especially for longer videos.

[alltheseas]

Primal and iOS Damus are investigating adding NIP-53 streaming

@hzrd149 does Applesauce support NIP-53 streaming?

@hzrd149 does Applesauce support NIP-53 streaming?

Applesauce v3 will have some helpers for reading NIP-53 events and creating / modifying them

Helper methods: https://github.com/hzrd149/applesauce/blob/861ccc74478c3f9bbe3b13a0e3e438db3ab48a40/packages/core/src/helpers/stream.ts

sorry for the lack of docs

Nostrability/schemata now contains a NIP-53 live scheme https://github.com/nostrability/schemata.

Devs and others can use to verify if JSON/events/kind implementations conform, or conflict with the spec.
