I turned off lirc_rpi and watched a 30min clip today and I didnāt notice any stuttering, not 100% sure either but it looks promising.
Sorry Iām away from home and wonāt be able to test until later today.
I can confirm that disabling the lirc_rpi module not only significantly improved the studder issue I was having with MMAL playback but also improved remote control responsiveness with my RC6 IR reciever.
this also worked for me!!

Good find.
cat /proc/interupts doesnāt show me any IRQs when I havenāt got a GPIO receiver attached to the board ,but popcornmix suggests the driver may still be doing something on the transmit side.
Iāll disable this by default in future updates.

Thanks @kartana
I still notice the odd shudder every so often but rather then every 5 seconds it is now every 5 minutes. I can definitely live with that.
Yeah @Jdiesel there seems to be slight stutter every few minutes for me too. No clue why. Might be the video file but I have no idea how to check the time stamps (that might cause stutter if they arenāt correct). But it seems to happen on most if not all my files so I think thatās not it. Removing the lirc_rpi module did improve things significantly though.
Can we not mark this as resolved. The big issue was the module but I mean I have this slight stutter every few minutes while using MMAL since using a RPi2. Regardless of adjust refresh and sync options, LAN or USB. Itās always there. There is nothing on CodecInfo that would suggest any frame drops etc. Iāve read a lot of threads on this issue and @popcornmix most of the time suggests using OMXPayer instead of MMAL but is this really a solution? I find the quality from OMXPlayer worse. The stutter is gone when I switch to it though. What is causing this?
Edit: have you tried using OMXPlayer @Jdiesel?
Ok,
Iām having similar issue but noticeable only on live TV streams.
I have to disable MMAL acceleration in order to get smooth playback. When MMAL is enabled it stutters every 2-3 seconds.
Tried playing various movies from NFS and they are fine with MMAL enabled.
Any ideas?
The stutter returned yesterday without changing anything. At first I thought it was the file but I put the SD card with OE in and it played fine. Both use the same addons (just a skin) and settings. I have no clue why OSMC doesnāt run properly on my RPi2. Iām out of ideas.
Are you running an OE Jarvis build, or an Isengard oneā¦? Itās possible there have been some changes which are impacting performance.
OE build is Isengard.
Iāll test OSMC Isengard as well as a OE Jarvis beta build in the next days and report back. This is driving me nuts, but other people donāt seem to have the problem (after finding the lirc_rpi problem) so not sure what to thinkā¦
Hello,
iām new here. After thinking getting crazy i stumbled upon this thread. Iām running a clean install of osmc with latest updates on my raspberry pi 3. All movies and the .kodi folder are mapped via nfs. With this setup i also get this stuttering without finding a combination of settings to avoid it. Iām out of ideas. This happens with 23ā¦fps, 25 fps and 50 fps videos on 23ā¦ Hz, 25 Hz, 50 Hz and 60Hz TV. And also only with mmal enabled. None of the audio and video settings (and combination of them) beside of enabling omxplayer seems to have any effect.
Iāll keep on reading this thread. If i can provide any infos to help to solve the problem, please ask.
Thank you,
Tom
ps. i already disabled the lirc module in config.txt
ps2. stutters appear aprox. every 20 seconds
ps3. i was very brave and tested the dev. version from the @gmc repo (rbp2-mediacenter-osmc 16.8-043). exactly the same.
ps4. removed all āmy osmcā related stuff, no change.
@tomnat
I assume you are running with āadjust display refresh rate to match videoā and āsync playback to displayā (they are both recommended).
Any peripherals (e.g. USB) attached?
Do you get this with a clean install, with no add-ons or custom settings? (Add the two settings mentioned above and disable lirc module)
Do you have the issue with openelec? That may narrow it down to being a kodi issue or a kernel/distribution issue.
Thank you. It happens also with the settings mentioned. There is only a osmc remote connected via usb. There are no additional addons installed.
I havent tried openelec yet. Iāll give it a try.
Thank you,
Tom
For completeness could you unplug then when playing? (or use a standard USB keyboard instead).
Genius! Its the remote!!! I have now testet multiple times with and without the rf usb dongle. Every time the usb dongle was connected, the stutter was present.
Iām now happy to know the reason and sad, thats the remote.
Thank you!
Tom
The remote dongle shouldnāt be problematic. I have used it with MMAL testing and havenāt experienced issues.
I had a customer recently purchase a remote and report similar symptoms, but after removing the lirc_rpi entry from config.txt, he has reported that the issue is resolved.
I will do some more investigating and also send one to @popcornmix. Iāll keep you posted.
