Some thoughts about video playback(not the usual ones, I know these ;P )

[Comrade_AnoreX]

Hello rockboxers,
I have a question regarding video playback(and no it's not how to encode or how to play it in the H10, I know all these(mom tells me I'm smart all the time :P).
When I looked at the "MpegPlayer Plugin" in the rockbox wiki it said that most devices support it(for example - iriver H300) but that the plugin itself DOES NOT SUPPORT AUDIO PLAYBACK.

My question is - If the plugin itself does not support audio playback? does that mean the H300 Rockbox users also don't have video with audio?
Also, If the MPEGPlayer plugin does not support audio playback, Don't the Devs(bless them) "just need" to write a new video plugin that does support audio?

Sorry If I puzzled you with my stupidity, I'll appreciate any answers

Yes. No one has implemented proper audio playback for video in the plugin itself so no one has it.

No. They don't need to write a new one. They need to optimise and try to implement audio on the existing one. This plugin is at the very first stages, it's a work in progress.

Also, the plan is to use the coprocessor for audio decoding. Unfortunately, for several reasons, they haven't been able to get any further on this as they cannot yet initialize the coprocessor itself.

It will be done when someone steps up and work on these things

If you read the coprocessor flyspray page you'll notice that it works really well on most ipods, but audio playback doesn't work on the H10 for some reason with this patch.

So it's nearing the point of being useful.

I'm curious which coprocessor flyspray page you're talking about. The only one I see (and the only one I know of) has the primary developer saying that threads aren't actually being run on the second core. Which is the case, we still can't get code to execute there independently.

If you've seen somewhere else that actually says it works really well, I'd be curious to see it, as many of the developers would be interested in such advancements.

This one: http://www.rockbox.org/tracker/task/5755

Scroll down the the bottom of the comments and you'll see the developer has the music decoder playing on the second core.

o. They don't need to write a new one. They need to optimise and try to implement audio on the existing one. This plugin is at the very first stages, it's a work in progress.

I think thats interesting^^

Woah! Never seen that... downloading now to make a build to try out...

[edit]Well, now you just need to resize mpeg movies... not also have to worry about removing the sound... but sound still isn't being output (as it says on the patch...).

Still, a big step in the right direction

Mad Cow: If you read ALL the way, you see him comment that threads he thought were running on the second core weren't. It does not work.

so angry are we going to see this in a possible future build of yours or at least a test build ^^

Another thing that needs to be implemented is fastforwarding and rewinding. Hopefully that will come soon also.

Oh, I misunderstood that. I thought he meant the threads were running on both cores.
