Re: GStreamer 1.0

if you compile from source a recent (more recent than my last reply) version of ffmpeg you'll find that fbdev now works on the pi. I would like to see some dispmanx support in gstreamer though.

Re: Dispmanx VNC Server

I got this to work on Openelec on the Pi. Performance was pretty bad with 1920x1080, as expected :). But not too bad with 720x480 (composite video monitor connected locally). You get XBMC menus and video playback, and mouse and keyboard work. dispmanx_vncserver uses about 20% CPU when running, and g...

Re: Project idea: RPi as slingbox type server

I was getting similar issues when I specified "sync=true". With "sync=false" things started to work. It looks like there's metadata coming though but no actual payload. The only other thing I could suggest is to try streaming a file out to tcp - such as: ./gst-launch-1.0 filesrc ...

Re: Project idea: RPi as slingbox type server

I'd probably need a bit more info about your setup to really help. with gstreamer, try "sync=false" at the end of the pipeline. with ffmpeg, I'm not 100% sure it will accept a tcp:// url as a source (input).

Re: Dispmanx VNC Server

Just an update - I've found that if I stop lightdm and run xbmc in standalone mode, I do indeed get XBMC menus and video playback via VNC! Excellent! Of course it's laggy and choppy, but it's a massive step forward. Now if we can feed Dispmanx_snaphot into omx.broadcom.encode we should have somethin...

Re: Boblight possible?

On a slightly different topic, but you guys using boblight on the Pi should know the answer - is there a version of XBMC on the Pi that renders all video that can be accessed with DispmanX including video playback and the GUI menus? I'm wondering because I want to set up a headless XBMC and control ...

Re: Dispmanx VNC Server

hanzelpeter, I've found it a bit hard to work out what will work using hello_encode because all it does is take an internally generated yuv test pattern and encodes it to a raw h264 file. I've changed the constant to def.format.video.eColorFormat = OMX_COLOR_Format16bitRGB565; and the output is just...

Re: Yet another openmax transcoder

Hi lorddoskias Do you think you could write a short "compiling omxtranscode for dummies"? I've tried and failed at the first hurdle. I've read the README which mentions using the Makefile.include inside the /opt/vc/src/hello_pi dir, and the libraries and include file from the /opt/vc dirs....

Re: Tvheadend transcoding using OpenMAX

Gstreamer can certainly access the http video streams that tvheadend makes available. I had a play with this a few days ago: http://www.raspberrypi.org/phpBB3/viewtopic.php?f=29&t=15426&p=383182#p383182 - basically just accessing the MPEG2 streams via the http interface and outputting h264. ...

Re: Dispmanx VNC Server

Looks very interesting! I've been looking for a method to access the XBMC GUI (and video playback) remotely. Most raspberry pi implementations write directly to GLES, bypassing X11 and /dev/fb0 and so the GUI can't be accessed this way. Can dispmanx access what's being written to GLES? Ultimately I'...

Re: GStreamer 1.0

Updating on my progress: I'm able to grab /dev/fb0 about once a second and record it as a .h264 file. But I'm not able to mux it into any kind of useful container. Here's my pipeline: gst-launch-1.0 -v multifilesrc location=/dev/fb0 ! videoparse format=29 width=1680 height=1080 framerate=30/1 ! deco...

Re: GStreamer 1.0

I had a good go with mythtv earlier this year - that is a good suggestion as it does have transcoding ability. But I've found that the setup is very finicky - it's very hard to get working, I find. I found tvheadend to be much easier and more stable. There's a transcoding fork of tvheadend which loo...

Re: GStreamer 1.0

Hi, I'm looking to revisit an idea that a few people have had over the past year - to turn XBMC on a Raspberry Pi into a kind-of Slingbox-type device. I'm new to gstreamer and doing graphics stuff on the Pi but have played with FFMPEG for a few years now. To create the "slingbox" I'm think...

Re: Project idea: RPi as slingbox type server

I've just done a proof-of-concept of the transcoding of an MPEG2 DVB TV stream into H264 and viewed it over the internet. On my home network I have a tvheadend server (not on a raspberry pi but I understand that is possible). With tvheadend you can access any DVB stream as an http source: e.g. in VL...
