video not playing on a CM3+ (Raspberry PI 3B+)

(1/1)

Facel:
I just have installed MC27 on my Allo USBridge signature which is based on a CM3+ module.

I have a NUC running MC Library and my video are stored on a Synology Nas.

When I play a video, I have very important stutterings and the cpu seems to be overloaded.

For testing purpose I have simply replaced MC27 by Libreelec/Kodi and I have no problem for playing the same video files  !!!!

Thanks for your help and suggestions

JimH:
If you're running client/server and using a NAS, there are a lot of places it could break down. 

The client (the Pi) may not be able to keep up with the video.  That it works with other software may mean the video type is different.

Conversion on the server.  Try something else.

Bandwidth related to video type.

Facel:
 As soon as I play a video MC is using a max of power from the cpu.

On a standard raspberry 3B+, does MC run flawlessly most of video files (TS, MP4=>(H264-Mpeg4- AAC 48KHz)  MKV => (MPeg2/720x576-/ PCM 48Kh/ -16 bit / AC3 - 48Kh))  ?

With librelec I can play the same files in the same config (MC media server- video fiels on the Nas- Raspberry 3B+ as renderer)

Hendrik:
Hardware Acceleration on the Pi3 is not supported yet, because they do not support any kind of standards API to do that, and a RPi specific solution is still in the works.
On a Pi4 you can play most of everything below 4K resolution on CPU decoding, the Pi3 is just a bit too weak for that.

Facel:
Thank you for your explanation.
Do you know when this RPI specific solution could be released ?
