Stuttering issue
Hello,
I am experiencing a stuttering / freeze when playing videos. Unfortunately it is quite random and unpredictable. Things can go well for several hours and suddenly starts lagging. All i can say is :
- videos are H264
- videos are quite high resolution like 10000 x 1080
- latest Millumin v5
- experienced the issue on macmini M1 and MacPro M2 Ultra under macOS Tahoe
- Sending the video over the network via NDI
- tried different locations in the building (source and destination)
- Never had this issue several months ago with the exact same setup (macOS was upraded since though)
I tried to transcode to HAP once when the issue happened and it worked but as the issue is random i can't tell if this solved it or if i was lucky...
Anyone experiencing such an issue ?

PS :
To solve the issue i just have to quit fullscreen mode and go back to fullscreen.
Use ProRes for video playback; H.264 and HAP are poorly-optimised codecs on Apple Silicon.
However, if you are using NDI for sending and receiving the video, the stuttering is likely due to network issues rather than playback.
hi thanks.
I will have a look with your suggestions. But i am not sure the issue has to do with the network. Everything was working flawlessly 5 months ago with the exact same setup. My network is a 10G optimized for NDI. As for codecs i have always primarily used H264 and HAP / ProRes when needed.
When Millumin freezes i had a look in the ressources monitor and everything (SSD, CPU, GPU, Network) was way below the limit as usual.
Is the NDI stream freezing/stuttering, or is it the actual playback on the source machine? If it's the NDI stream, then you have a network issue.
Regardless, as mentioned, H.264 and HAP are very poor choices of codec for Apple Silicon machines. Always use ProRes as best-practice.
No this is Millumin source freezing. Going fuulscreen back and forth fixes the issue until the next happen.
Noted for codecs, i'll try to change my recommended setup.
