YUNPM - a Java Media Player

[ReBirth]

@riven
I tried the lastest zip, and it runs well after I changed the exe. Now that's rock

[Riven]

Thanks for testing!

Can you explain what you mean by changing the exe? Did you swap the 32 and 64 bit versions, to make it load 'the other' exe?

[ReBirth]

No, on previous version (I forgot because I overwritted it) I had to add .exe extension to the only one ffmpeg32 file (became ffmpeg32.exe). The size is different from current dist which contains both 32 and 64 bit versions.

It seems I screwed up the previous zip then. Thanks for reporting!

[TimB]

I know it's an a-few-months-old topic but this looks really useful. Have there been any changes since 0.8.4?

[Riven]

Nope

Please report it if anything is broken, or if an obvious feature is missing!

[TimB]

I started a discussion on this thread at the JME3 forums, will see what the developers there think about how practical it will be to integrate before I do anything.

Any chance I could get some sample code for rendering/controlling this in a slick2d game?

I wrote an Example of GstLWJGL, another media player to use with Libgdx.
I should post it D:

I just spend the past 2 and a half hours reading all of this...
Please excuse my stupidity, but how would you implement this in a preexisting java program? I am not a creator, I am a modder. I want to add an intro clip to the game I'm modifying... Would I drop the jars in the bin folder, where the other jars(like game.jar and lwjgl.jar and natives etc.) are? Please help... and don't be prejudiced, I'm not here because I already know how to do everything, it's because I want to LEARN from you guys... and if you don't want to help me, PLEASE don't ignore me, just leave a message saying that you're ignoring me...

Thank you in advance,

Well you gotta understand the code. Its not hard but if you cannot program at all...

[ziozio]

I have a feature request, can you add a feature so I can set the ffmpeg location where the binaries are? Currently its hard coded

EDIT : One more request. If there is no audio in the video it currently throws an error as it tries to use a null InputStream in the AudioStream (line 52, in Movie.java). Can you add some provisions for this scenario?

Thanks

Is there any source code for this available for download?  Or an easy way to modify the VideoPlaybackTest class?  I'd like to take a look and mess around with the options a bit.

[Riven]

The source code is included in the jar files.

Version 0.8.8 of YUNPM



Changes

• Made streaming in video frames fully asynchronous, shaving off 4ms per video frame
• Fixed volume control, bug in mouse-wheel handling (that nobody noticed this is telling )

The only part of the library that is blocking now is glTexImage2D, which is about 2.2ms per 1920x1080 frame - which can be offloaded to a PBO, but only really matters if you have more to do than rendering that video.

I'm glad you're still maintaining this project. I will definitely be using it if I ever need it!

Version 0.8.9 of YUNPM



Changes

• Added support for videos without audio (thanks ziozio for reporting)
• Added support for PBOs
• Created Git repository: https://github.com/riven8192/LibMedia

That's some impressive code. I just spent an hour perusing through it

[ReBirth]

A new update in less than 24h, impressive!
