This thread sounds similar, although it's old enough that I doubt your issue is exactly the same:

Re: OSD (on screen display) w/o X

I haven't recompiled or run poptart in quite a while, but I can try to reproduce your error. No promises as to timing; I've moved recently and haven't reconnected any Pis.

I'm guessing you will get this same error if you just try running poptart with some test message, but would be good to verify.

Re: OSD (on screen display) w/o X

Thanks, that's a great help. We're using it for visual displays. So, omxplayer is cycling through a directory of videos, and the idea is that poptart will add additional info (time, weather, opening hours etc) along the bottom of the screen. Hence scrolling would be awesome :) Currently I'm using a...

Re: OSD (on screen display) w/o X

I tried increasing my GPU memory from 64 MB to 128 MB in raspi-config and that seems to get rid of the assert failure. So I think it is a memory issue. I've always thought it would be better if poptart didn't open a full screen window with transparent background just to draw in a small area of the s...

Re: OSD (on screen display) w/o X

So, the assert is failing due to failure of eglBindAPI. eglBindAPI seems to fail when trying to bind OpenVG API when omxplayer is already bound with a different API. I don't understand all the details of EGL that well, but this seems to be an issue that only comes up when both omxplayer and poptart ...

Re: OSD (on screen display) w/o X

Hmm, no idea. I've never tried it with omxplayer. Sounds like omx is claiming the whole screen resource or something. I'll let you know if I figure anything out.

That did it, thanks :) Are there any switches to change behaviour for it at all, wondering if I could maybe change the display time?

Sorry to post on such an old thread, but this is exactly what I'm looking to achieve - I'm missing this 'libvgfont' thing, and I'm trying to work out how I go about getting it (and/or any other pre-reqs for OSD/poptart)? So, on my version of Raspbian the VideoCore demo stuff is under /opt/vc. If yo...

Re: How to Run NFS Server on Raspberry Pi

To date it seems reliable, it can handle files much bigger than 2GB and also offers decent performance (7MB/s write, 5.7MB/s read). This is pretty much the most that can be expected of the Pi's 100Mbps network connection. How do you (or others with decent speed) have your drive setup? What filesyst...

I'll take a look soon to confirm still working. Another option you might consider is to run an X program in a minimal window mana...

Re: pianod+wsgw: Pandora client/server with nice web interfa

Hmm, okay making more sense now. As you know, if you run pianod as a normal user it doesn't do any setuid. But if you run it as root then it drops user to whatever you give as "-n" or "nobody" by default. When running as a server, it runs as root so then drops to nobody. The thing that was messing m...

Re: pianod+wsgw: Pandora client/server with nice web interfa

Well, I'm a bit stumped on this issue. I seemed to have trouble with -nroot when I first tested it for you, but now -nroot works as well as -npi. The trouble I still have is -nnobody, which is the default if you invoke pianod as root. The trouble with user nobody accessing the sound card seems to be...

Re: pianod+wsgw: Pandora client/server with nice web interfa

If you're on Raspian, try -npi or whatever your normal user is. There seems to be some issue with accessing sound devices as root or nobody; on my system it works as pi. I'll look into this more, but hopefully this is a stopgap fix for you.

To answer your sub-question, the method I have been using for checking whether a sound device on the RasPi is already open is along the lines of:

I believe the -n root was the solution for GoneWest. I am having this problem as well now; will look into it. For me, it works if I run pianod from a terminal as user; is that the same for you?

Re: Bittorrent Sync on RPi

It did better with just synchronizing new files from the desktop to the Pi. ~15 GBs transferred so far without problems. So I think it's just indexing large directories on the Pi side that caused problems.

Re: CLI recommendations

If you are logging in and out a lot, GNU screen or tmux, etc are worth learning. Assuming you are on bash, bash_completion is probably worth installing, and you can play with writing your own completions for less standard commands that don't have them; probably something like yt might be a candidate?

I should also mention that there have been a good number of commits lately around audio device selection, etc., so things could be changing in that area already. I haven't been following this closely.
