Not sure if this is the best thread to post this on, but you guys seem to know what you're talking about and it's all kind of relevant :) I'm trying to render h.264 video to a GTK widget in python, utilising the hardware acceleration obvs... I can't get OMX player to work with a widget, nor can I fa...

Still no joy with this, it's driving me crazy! Forcing it into DMT mode just goes straight into 640x480 half the time when it boots up. So I've put it back to letting it pick its own resolution - starts off fine in 1920x1080 but after an hour or two drops back to 640x480 4:3...

summershere

Have changed it to DMT now, and forced it to mode 82 - will see if that sticks... does that still support audio via HDMI if I force it?

It's a monitor with speakers, which is kind of a TV I suppose?? ;) Output of that below... none are preferred or native though..? root@pi:~# tvservice -m DMT Group DMT has 12 modes: mode 4: 640x480 @ 60Hz 4:3, clock:25MHz progressive mode 8: 800x600 @ 56Hz 4:3, clock:36MHz progressive mode 9: 800x60...

Back to this thread unfortunately - thought it was fixed but it isn't :( Once again getting: root@pi:~# tvservice -s state 0x12001a [HDMI CEA (1) RGB full 4:3], 640x480 @ 60Hz, progressive ...and yet it's correctly reporting native resolutions: root@pi:~# tvservice -m CEA Group CEA has 11 modes: (pr...

What do you see if you re-comment the forced HDMI group & mode above and run the tvservice command as shown here: http://www.cpmspectrepi.webspace.virginmedia.com/raspberry_pi/MoinMoinExport/OptimisedDisplaySettings.html ? (I'm wondering if you've not chosen the best 1080p mode for the monitor/TV) ...

Short - none of them are greater than 60 seconds...

I've got omxplayer cycling through a number of 1080p mp4 files in a bash script. After a while, it hangs on a blackscreen. Looking at the processes, it hangs on the same mp4 each time. If I delete it, it picks a different one and hangs on that each time. This is what fills the log file up when it's ...

summershere

Hmmm, it has selected 60hz though for some reason, should be 50hz here...

Code: Select all

state 0x12001a [HDMI CEA (16) RGB lim 16:9], 1920x1080 @ 60Hz, progressive

Ok, have done this... just rebooted so will check it throughout the day. This is what I get from a tvservice -m CEA : Group CEA has 11 modes: mode 1: 640x480 @ 60Hz 4:3, clock:25MHz progressive mode 2: 720x480 @ 60Hz 4:3, clock:27MHz progressive mode 3: 720x480 @ 60Hz 16:9, clock:27MHz progressive m...

Anyone got any ideas here?

summershere

Connected to a 1080p display (Acer), this pi is running OMX Player. After a while of working perfectly it drops down to standard definition. Any ideas why? Is it anything to do with the overscan? The mp4 files are all 1080p I believe. config.txt: [code] # uncomment if you get no picture on HDMI for ...

Just to update: -6000 did work fine for me, thanks for your help.

summershere

Thanks for this - still struggling with it though. It's ignoring the volume, and I wonder if it's anything to do with the negative value? I have tried omxplayer --adev hdmi --vol $(cat /home/pi/volume) $file with the contents of 'volume' as -600 and "-600". I've also tried specifying '--' on its own...

summershere

I'm running omxplayer (with audio through HDMI), and I'm having trouble setting the volume control using the --vol flag The help page says that the setting is in millibels, but I don't know what to gauge this on. Any ideas? Ideally I'd like to set this from a text file, so perhaps: omxplayer --vol <...

summershere

Chinasaur, just sent you a PM - it seems to just sit in my outbox rather than move to sent messages though. Let me know if you don't get it as I can't tell whether it's actually gone or not... :/

I've looked briefly at subtitles, but due to the timed nature of them it doesn't really work - need something a bit more autonomous really. I've also had a play with various kiosk apps, but haven't found one yet that A) runs on the pi, B) plays video, and C) isn't just someone else's wrapper around ...

summershere

Incidentally, if I use stdin or the -c flag, it seems to add a couple of carriage returns somewhere, moving the text up the screen. Also, the grey background is still only appearing on long text. So for example: poptart "hello hello hello hello hello hello hello hello hello hello hello" -s 100 Has t...

summershere

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 ...

summershere

That's great - changed the GPU memory and it fixes the issue for me too, thanks for that. Is there any way of scrolling the text? Also I notice that the background boxr only shows up if there is a lot of text (if that makes sense, and it's not just me?!). Still trying to work out the switches, I'm n...

summershere

I'm looking to achieve some form of information display via On Screen Display. I've been playing with various OSD libraries, but it seems that none of them can 'poke' through OMXPlayer (unless anyone has achieved this??) So it crossed my mind that another way of doing this would be if there was a wa...

summershere

Thanks, I'll give that a try.

Odd issue, I seem to get an error if omxplayer is currently showing a full-HD video:

Code: Select all

assertion failure:graphics.c:269:gx_priv_restore():egl_result
Aborted

If the video's less than 1080 it displays fine. Any ideas?

summershere

That did it, thanks :) Are there any switches to change behaviour for it at all, wondering if I could maybe change the display time? Ideally I'd like to run it from a background process, overlaying information on whatever's running on the console. It's kind of surprising (to me at least) that there ...

summershere

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)?

summershere

I'm trying to come up with a way to do the following automatically on startup: 1. Open a web browser 2. Go to a URL 3. Start playing the embedded video (HTML5) 4. Set the video to fullscreen Has anyone achieved this, or can you think of a way this might be achieved? I guess I might need some form of...
