As mentioned yesterday evening on the main page of the blog dealing with the OSMC’s March 5th update, after updating osmc and reboot, I have experienced sound stuttering when playing several videos (the image is fine, just the sound that stops for a second or two, sometimes less, and then comes back) . I have tried to rollback to previous version of OSMC, and then the problem disappears and everything works flawlessly.
I have a similar problem after the February update on a Pi2 where video files come are shared via NFS (declared in /etc/fstab).
Audio can go out-of-sync sometimes (I skip to go back in sync). This happens with MMAL player and I don’t reproduce it with OMX. Before the last update, this problem did not happen and as far as I know, only MMAL was enabled then.
So I have both OMX and MMAL switched on in the video settings. To be honnest I don’t really understand what it means to have both selected at the same time, I would have expected them to be mutually exclusive. Can someone explain?
Nevertheless, no more sound issue on my quick test. I’ll try on more videos this week end to confirm.
Thank you dillthedog.
I’d recommend you switch off MMAL. I agree, it doesn’t (seem to) make sense to have both enabled at the same time. Perhaps someone more knowledgeable can explain if/when having both enabled would be useful.
With both OMX and MMAL selected it uses OMX as default and i believe switches to using MMAL for anything the OMX can’t play for example using a2dp alsa streaming it uses MMAL and so forth.
I always use OMX as there is no jutter when navigating through menus with video playing.
If i’m reading the comments in this pull request correctly it looks like they will be dropping OMX player from v19 onwards. It would be a pity as it is great lightweight all round player, unless by v19 videoplayer (mmal) will have improved a great deal and that it doesn’t affect navigation performance that OMX will no longer be needed.
Same problem here! Popped up with either the March or the February update, not sure if I got two months in one go or not. Also running rpi2b. Issue seems to be related to MMAL, here are a few lines from mine that popped up during the stuttering:
I’ve tried with both HDMI, and ALSA hifiberry digi. Both experience the same issue.
Also, I tried running the nightly builds as well, problem only seem to get worse (more often) in the latest as of last night.
I’ve attached the log file from a fresh boot with two plays of my show “tvshow.mkv”. The first run was with the USB (no issue this time!), and the second run is from the network share. You can clearly see something happening around 14:44:14.530, where the error value farthest to the right starts peaking in the negative direction - this is where the stutter was noticeable.
