Re: Xibo player (work) on raspberrypi

Dear all, sorry for my absense from the group for this long time. But I am sorry to say that it also will take a while before I am able to contribute again. For everyone trying to compile on the RPi 2 keep in mind to update the include.gypi and env.arm files to reflect the new processor I have not t...

Linking gives undefined reference to

Hello all, I am busy adapting libAVG to run with OpenMAX support on the RPi. To do so I took a few files from OMXPlayer and included them into the video directory of the libAVG source. I set the defines so it compiles for my OpenMaxDecoder.cpp. But now when i try to build the files in the directory ...

Re: Xibo player (work) on raspberrypi

Hello CryptoMania, HTML5 is not support due to the fact that berkelium is based on Chrome 11, which is a very old build. Since berkelium can't be build with newer versions of chrome we currently are stuck with HTML4 support. I have been looking at the new epiphany browser currently released by the R...

Re: Xibo player (work) on raspberrypi

Hello Ghans,
thanks for the info. I will look into how the other players use FFMpeg/LibAV to demux the thing.

Re: connecting OMX.resize to OMX.EglRender

Hello Don,
thank you for your pointer. Thanks to the code I figured out that the problem lay in the colorspace I was using. RGBA8888 doesn't fall well with the Egl_render component. I changed it to YUV420 and all was well.

Thank you,
Hellbender

Re: Xibo player (work) on raspberrypi

Hello All, Small update, yesterday i got the resized video working insize a VideoNode. Problem now is that only the test video from the hello_video code works. I am going to search for the reason omxplayer can play this video and the demo code can't. I presume it has something to do with the fact th...

Hi All, I think it would be nice to give an update. I am currently in the middle of trying to get the video to resize to the texture size. This seems to be a royal pain in the ass. I can't figure out why I am getting paramter invalid or state invalid errors. So i have resorted to copying a piece of ...

You could take the DownloadManager class from the python client. This will download the content to the local client. This content can be parsed and used in a self build client.

Re: Xibo player (work) on raspberrypi

@Mika2413, you can configure after how many seconds the client should ask the server is any updates are available. Out of the top of my head it does this once every 15 minutes or so. It is set in the site.cfg file. @elofty, What is wrong with the text option, because as far as I am aware this is wor...

Re: Xibo player (work) on raspberrypi

Dear Cronoss, OpenMAX is giving me some headaches in that it isn't calling the callbacks telling me it is done rendering a frame. So it consumes frames but looks like it never finishes them. Several forum posts relate to this topic, but it seems this was fixed in the firmware back in februari, so I ...

Hello feddersenlu, I think the javascript clock could be an issue, this since loading webpages in berkelium is really slow.

Re: Xibo player (work) on raspberrypi

Hello Shampooman,
that's a nice screen :-)

It looks like the resolution of the screen is not the resolution set in /boot/config.txt and site.cfg.

Please check the original resolution of the screen ( probably someting like 1600x900 or so ) and set those values in both files.

With regards,
Hellbender

@ShampooMan I can't be completely sure what is going on, but I/O errors mean that the PI can't read or write from it's SDCard. Do the errors go away if you reset? Or even if you reload the image onto the SDCard? @Peter-Pim Could you check the log ( or even the information screen ( press i on the key...

Hello Shampooman, It looks like the SDCards you are using are at fault. One of the things I have noticed is that SDCards are more prone to go fault than an USB stick. So I used small factor USB sticks for storing fast changing files. Eventually I settled for FujiFilm Class 10 SDCards which haven't g...
