Re: Binaries and source for 64 bit kernel for RPI 3

Dear David,
I found the source of Problems now in a program which was loaded in rc.local.
It stop use of reboot shutdown etc.
After removing program from rc.local all cmds are useable.
So it is not related to kernel, i guess.

Re: ffplay / ffmpeg

I need a library, not a program.
On which lib base the omxplayer? As I could read, it is the ffmpeg. So there seems to be the same way.

ffplay / ffmpeg

Hello,
I rebuild X264 and ffmpeg in the way as it was described on the ffmpeg-site-pages.
when I start ffplay to show a mpeg4-video (without sound) it is to slow. It only Plays 0.5 Frames per second in full-hd.
How should I set the Parameters by compiling or which misstake had I done?

Re: HDMI detect

Also, die Auflösung kann ich über SDl genau abfragen, das funktioniert ganz zuverlässig. Allerdings wird die wohl nur beim Init durchgeführt ;-(
Das klappt auch, wenn man Xwindows remote ausführt.

Re: Network Problems with Ethernet and WiFi Both Configured

Sorry,
I missunderstand why it is a problem to have both connected and with a ip-adressed at the same time.
At my home it is all the time working (wifi and cable connected). I can use putty to connect both networks. Also at the same time. There is no problem (if you had a good power supply).

Re: how to use OpenVG with C++

Now, it is linkable. But it shows nothing.
So I start with a workaround: I use C in a service for the presentation layer and a c++-program for the rest. Means, I give up to mix a C and a C++ here
