Support webm video (VP8+Opus)

[Ghabry]

Just for completeness, the only true Video format 👍

[fdelapena]

And the only true audio format :P

[carstene1ns]

What about VP9 video?

[fdelapena]

What about VP9 video?

What about AV1? IETF NetVC candidate from AOMedia (featuring Xiph's Daala + Cisco's Thor + Google's VP10).

(...) the only true Video format 👍

It looks like it will be mostly ready when we will implement this feature 😋. What about using a frontend library which supports multiple codecs such gstreamer or ffmpeg?

[Ghabry]

What about working, uncompressed avi before we think about anything more complex ;)

[Ghabry]

Was in contact with the Aedemphia devs. They plan a new release this summer and assuming the Player can play the videos flawless (compared to the glitched playback on Win10 with Direct Show in RPG_RT) they would likely "go with us".

What about Aëdemphia video? The only thing missing is video support to make the game 100% playable with a more efficient rendering than RPG_RT.

Hello,
I'm the Aëdemphia developper. I admire the work you've done with EasyRPG which is very impressive. I've been told that posting here would increase the chances of getting one day the video feature so... Yes, I'd be very interested if this feature would was done, and would be very happy to use EasyRPG for my game. :)
Best regards and thanks for the great job already done.

Wanted to follow that previous message from Tontonnonor, as rpg maker gamer, easy RPG is almost perfect, I was able to play perfectly at Velsarbor on my phone, and what a great pleasure.
Such a shame some games like Aedemphia and others using videos can't work... Hope you'll be able to add the video feature one day! That's probably one of the only missing thing to consider Easy RPG as a perfect Alternarive.
Good job for the good work you already did, and thanks !

[Ghabry]

Okay okay, I will take a look.

The most likely video format that will be supported is "webm" which contains VP8/VP9 video and a Vorbis/Opus audio feed.

Will need to get libvpx working first (and a parser for webm which is just a simpler mkv container. The library libwebm is not packaged alot and has a CVE since 3 years).

Thanks a lot Ghabry! You're the best. Can't wait to play Aedemphia on mobile!
Any ETA maybe? Weeks/months? Sorry you probably don't know yet but I just wondering.
Anyway thanks a lot for your great job.

[Ghabry]

I'm completely unexperienced with anything video related (and audio, well... it kinda works?) so I can't give an ETA.

First goal will be to write a standalone video player. When this one works integrating into EasyRPG will be simple.

[Ghabry]

I took a look at this again and this is even less documented than FreeType/Harfbuzz. For the latter I could look at SDL_TTF to figure some stuff out but I don't know of a single, simple (!) library that uses libvpx for Video & Audio playback.

The example decoder code is close to useless because it lacks essential things like: Timing, Frame dropping or how to synchronize video & audio output.

I will put this on hold unless somebody finds a simple example program for playing vpx-encoded videos where I can get working code from.

@jetrotal found this: https://github.com/brion/ogv.js

Is a video player for ogv and other formats written in C with JS/WASM interop.

This one looks very promising as a reference.
