With #0406+ builds I have noticed that the reported FPS in kodi system summary goes down to ~7 when idle and 30-40 when scrolling the menu and while playing a movie it's low again around 1-9fps.
#0405 sits at 30fps when idle and when playing the same movie at 25fps.

Lower fps reported is correct. It no longer counts frames that were skipped when nothing had changed:

Ok, that makes sense.

I will make a sample now.

For info, I build libvpx and enable it in ffmpeg ( --disable-decoder=vp9 --enable-libvpx ) instead of built-in vp9 decoder, it's a little faster but not enough to play vp9 files at 720p or 1080p.

During video playback - omxplayer - GUI is very slow.

Affected (Pi2) builds are: #0414, #0415 and #0416.

Build #0413 is fine.

Attached #0414 log:

@slack3r - this is by intention and there is a setting for it (limit GUI updates when playing video).

Thank you da-anda, but I think something is broken:
only setting 'GUI updates limit' to "unlimited" solves the issue.

Build #0413 is fine.

What do you do with GUI when video is playing? Just OSD interaction, or are you backgrounding video and then browsing through menus?

[popcornmix]

For info, I build libvpx and enable it in ffmpeg ( --disable-decoder=vp9 --enable-libvpx ) instead of built-in vp9 decoder, it's a little faster but not enough to play vp9 files at 720p or 1080p.

Does it make use of all cores?
Any view on how much faster it is? E.g. if you play an SD file what is the percentage CPU with default ffmpeg and libvpx?

I mean backgrounding video and browsing through menus: it is very, very slow. Try jumping at home screen and browse items.

To be honest I've never wanted to do this. Is this something you regularly do, or are you just stress testing.
The intention with the recent update is that the GUI runs at 10fps and video at full rate. The gui shouldn't be slower, it should just update less often so may look less smooth.
Possibly something else is going wrong - I'll need to test this.

Obviously there are some cases where rendering the GUI at full rate, and rendering video at full rate are not both possible
(e.g. 1080i video deinterlaced to 60fps running in PVR preview/channel window), and we need to decide whether smooth video or smooth UI is preferable.

I do this to check hardware temperature, for example. I know, it's not essential for normal usage, but with last three builds GUI seems running at 1-2 frames per second.

For me, the 0416 build is one of the best I've seen on my RPi2 for video playback. I'm only using dvdplayer and have disabled omxplayer. Everything just worked quite well... Skipping back and forth by large and small amounts, deinterlacing 1080i60, playing back 1080p60. I'm totally fine with the GUI updates being a second priority when video is playing.

Thanks for reporting. Please continue to report when things improve in builds as well as when things get worse.

I don't typically use PVR/live tv/deinterlace, but from time to time I test files using the IPTV PVR addon (which behaves somewhat like real PVR) and may make changes that appear to improve its behaviour. However I'm never very sure if the changes help real PVR use, and so if no one comments on the change, I may drop it as not having a proven benefit.

I use the rp1 with LiveTV and HD channels (1080i 50) and the channels mini OSD ('c' key) is painfully slow. It doesn't matter if I change the GUI updates limit to 10, 25 or unlimited.
