Re: Multiple Frame buffer beta testers wanted

Sorry for not being too specific about describing the issue - I thought it was KMS/FKMS V3D-connected, so I posted here. The right place to go is obviously https://www.raspberrypi.org/forums/view ... 8&t=243886

Re: Raspberry Pi 4 Thread - general discussion

I guess he might be referring to multi-head systems that utilize two discrete GPUs - one intel, one AMD/Nvidia. In those cases you will have issues with spanning single opengl/direct3d windows across two monitors (including modern web browsers - I see it happen on W7/W10 quite often). But the Pi has...

Re: Multiple Frame buffer beta testers wanted

Seems to me that Pi4 owners all are beta testers now ;) I have two devices (HDMI multiviewers, totally different brands and internals) that make the Pi4 fail on boot when both HDMI cables are connected. The kernel loads and starts doing something (four small raspberries visible), but then stops on a...

Re: Custom HDMI modes

I suppose writing about this issue in this thread makes more sense than adding a new one: I'm trying to make AJA HA5 HDMI to SDI converter work with RPi 2 (or any Raspberry in fact). I'm aming for the standard 1080i50 PAL mode. The issue is that it works only when: a) pixel encoding is set to RGB (l...

Re: H264 Decoder

@dom, what about High422 profile? omxplayer seems to accept it, but the image is not displayed correctly.

OpenMAX audio encoders

This question has been asked more than once before, but hasn't been answered:

Are there any hardware-accelerated audio codecs available through OpenMAX?

Re: Image stabilisation

Could anyone confirm that the video stabilization actually works? I don't seem to see any difference with -vs or without it in raspivid. For starters: field of view doesn't seem to change.

Re: USB redirector

You might have more luck with this one: http://usbip.sourceforge.net/ - I've seen it used on an embedded linux IP KVM running on some kind of ARM processor.

Re: omxplayer - GPU enabled video player

Hi there, As this is my first post, I'd like to greet all Raspberry Pi designers and users. It's a great community and (since last friday :] ) I'm thrilled to be a part of it. I just looked into the sources of omxplayer, and discovered, that the -d switch (deinterlace) works only for SD video (namel...
