FFMpeg Object: Synchronous Video Player

[defisym]

Here it is (Drop a random video with a name "NGGYU" into the folder. Couldn't attach it due to its large size)

And here are results of changing width and height on my end:

Also apparently videos continue to play even when the app is paused which sometimes crashes it for me.

Hmm, it's due to a stupid typo, passed both x scale in, sorry for that.



Please check the latest commit in repo.
If you don't familiar with how to use GitHub, you can just simply download entire repo:



then copy files under Extensions/FFMpeg/ToInstall/Files to fusion root.

Thanks a lot, everything's working perfectly now!

https://github.com/defisym/OpenFusio.../FFMpeg_230420

Bug fix
- fix big buffer sync issue
- fix stretch issue

Enhancement
- auto update props to avoid audio stops playing

B230520

https://github.com/defisym/OpenFusio.../FFMpeg_230520

New feature
- Set override codec to force extension to use it, e.g., use libvpx to support alpha channel of WebM files

Bug fix
- Fix SDL_Mixer pause when loading new video. old packet queue will block audio thread and which causes pause gap when SDL_Mixer is playing, as both shares the same backend. use spin lock to get rid of that pause.
- crash if video file has no audio channel

Enhancement
- Add popup for deprecated Force no audio checkbox.

https://github.com/defisym/OpenFusio.../FFMpeg_230620

New feature
- Get override codec name
- Reset display

Bug fix
- Pause in debugger or using pause action won't pause audio
- fix external clock sync issue
- fix clean cache crash if cache is empty

Enhancement
- ForceNoAudio is not marked as deprecated as external sync is fixed

So is it beta? And if so, what are known issues not currently fixed?

Really need that object as lack of ability to play modern video formats is one of the few issues I have with Fusion.

I'm using it in my game, and it seems to be fine for most cases. AFAIK:

- Hardware decoding is not rendered to surface directly; it has a copy routine so it's not fully hardware. You may get performance issues if playing multiple files together.
- For some video formats you need to set override codec names to play properly, e.g., default codec will ignore webm's alpha channel.
- Decrypt stream didn't implemented so if you are playing encrypted large files it will take more time to load, and may crash if file is too big to put in memory, but usually it's fast enough.

Hello,

Is it possible to add the ability to open network streams instead of just files?

I would very much like to be able to open rtsp streams (that has username and password in the link) as well as MPEG-TS UDP Multicast streams.

FFMpeg supports open from URL, but this object is designed to decode synchronously, to make sure there is something to display without gap.
Tested and it do can open but soon app freezes due to current packet queue & sync didn't take this case into account.
So it's a bit complex to implement this, using the multi-thread way ffplay uses, which means rewrite most parts of it.
Anyway, it's open source, you can implement it and open PRs
