The VideoLAN Forums

Good day,

I compiled MovileVLCKit as static libTVVLCKit.a. Video playback works good if I use UIView with small dimensions. But if you set the dimensions to Full HD. Playing lags (CPU usage cca 110%).

i have the same problem...and after a while streams don't play and i get VLCMediaPlayerStateStopped every time.
i also want to have two videos playing at same time (one is a preview of the next one) but that is not possible right now.

The tvOS SDK does not include the VideoToolbox framework at this point so we can't do hardware accelerated H264 decoding. We filed a radar on that, but no response so far. If you want efficient video decoding on tvOS, do the same.

For network streams, there is a regression in our code which we are aware off and will resolve (a busy loop in the network handling code), so performance will get better.

@Felix Paul Kuehne I tryed decoding same video and audio with ffmpeg and no problem. I is very fast.

Sample code from you needed then.

Further, are you actually testing on device?

No I tested on simulator. Device will be available month later :/

Sample code of ffmpeg or tvkit?

A sample showing the use of our code. I can't help with ffmpeg.

Further, since you don't test on device, it doesn't mean anything regarding the CPU load.

Finally, are you playing a network stream? if yes, what kind of?

Without such basic information, there is absolutely no way we can help.

btw i have the new ATV so if you need i can test on the device...

I'm testing a network stream (over LAN) from a DVB source, video is working almost fine...audio is terrible...scattered audio.

I'm testing on a real ATV.

What's the used network streaming protocol?

I'm using a URL like this
PS: opened a bug report about VideoToolkit..let's wait for Apple

Thanks for filing a radar on that.

Regarding the actual topic of this thread: this is a regression in our networking code which results in a busy loop. We hope to be able to fix it shortly but it affects all platforms and is absolutely not related to tvOS.

ok, please let me know and I will test it

@Felix Paul Kuehne this is my sample project on OneDrive: http://1drv.ms/1LZRVQL

Thanks for sharing. I'll check it out as time allows.

Ok. Thanks!
