Hello,
I use VLCKit inside my tvOs app and with 2.7.2, I've got a lot of freeze and what I saw is that the AppleTv cpu is up to 100%. The process which takes all the CPU ressources is h264 decoding.
Are you aware of this or do you want or need some more details from me ?

Thanks.

We are not aware of that and we need more information about the played media as well as an Instruments analysis.

Thanks you for your answer. I will give you more information about that this evening. What kind of instrument file do you want ?

Hi,
Here are the files. I hope it will help you to solve the problem.
For information, movie is stream over wifi to the AppleTv.
Thank you.

Impressive, thanks for sharing the traces. The used H264 profile is definitely supported, too. :/

Can you share an excerpt of the sample file with us on http://streams.videolan.org/upload/ ?

Thanks!

Thank you. I just upload a sample of the movie with the link you give to me.

Hello,
Did you receive the sample file ?

Thanks

Yep, thanks! I couldn't check it thoroughly yet, as my Apple TV is currently some 9500km away

Will do next week.

Ok no problem thank you very much

Hello,
Face to this problem, do you recommend me to use the master branch with videotoolbox inside ?

Thanks

For information, I've tried with VLCKit 3.0 and the same file and the result is the same... so CPU is more than 100% and FPS go down to about 10.
Thanks

Sorry i got questions about v3.0
How to enable Videotoolbox it seems disable ?
How can I check if it's enabled ?

I activate debugLogging but no trace of hardware acceleration ?

Thanks

Hello,
I'm sorry for that post but have you got any news for my problem ?

Thanks
