Re: LibreELEC chrome launcher Qs

LibreELEC is designed to work as an appliance. Copy it to an SD card and use Kodi without having to know there's an OS underneath it. You can install a lot of different programs via addons (from within kodi), if the one you want isn't there you can install the docker addon and get bascially anything...

FYI: Netflix addon 0.13.8 was just released, it looks like it fixes the issues in the latest Milhouse builds.

Re: Multi-OS Media Centre

LibreELEC doesn't have a text-mode console, if you want/need to change something you have to do it via ssh - see the wiki for info https://wiki.libreelec.tv/accessing_libreelec But you can safely ignore the manual libwidevine installation instructions, this is no longer needed.

Re: Multi-OS Media Centre

Just downgrade your installation to the 0603 build (copy the 0603 tar to the update share and reboot), this should be enough to get Netflix working again.

Not sure about the Amazon addon, I only have Netflix.

Re: Multi-OS Media Centre

We just noticed that Netflix stopped working in the latest Milhouse build (0604) and are currently trying to find out why. Please use build 0603 for now until we fixed that.

Re: Multi-OS Media Centre

Berryboot is not supported with LibreELEC - it swaps out the kernel and firmware to different versions and causes lots of issues - but you can use NOOBS or probably PINN (never tested the latter myself, though) if you want to create a multi-boot SD card. Kodi 18 / LibreELEC will include (almost) all...

Re: Sending keystrokes to console process?

You also need to add ioctl(fd, UI_SET_KEYBIT, KEY_P); at the beginning (after the KEY_SPACE UI_SET_KEYBIT ioctl). The UI_SET_KEYBIT ioctls set which keys are supported by your "virtual keyboard" and you have to call it for every key you are going to send out.

If you are running a text-mode application you could start it in "screen". screen sessions can be shared and you can then ssh in and attach to that screen session (see screen manpage for details). Another possibility is to use /dev/uinput to inject input events - this can be mouse, keyboard, whateve...

Re: Multi-OS Media Centre

I'm not familiar with Retropie but keep in mind that in general you'll also need the inputstream.adaptive addon (plus it's dependencies) - which is already included in the LibreELEC testbuilds I linked to but may be missing on other Kodi 18 builds/installations.

Kodi 18 (Leia) supports Netflix natively.

Re: STICKY: The I2S sound thread.

I'm right now applying a DSP to the Raspberry via I2S. I'm using a modified simple card overlay as posted a few pages before. The DSP runs in I2S master mode and provides the clocks for the raspberry. Therefore I configured the codec to be the master. That's the code I'm using, all needed modules g...

You can use the alsa softvol plugin. See here for details viewtopic.php?t=204133#p1267389 - make sure to replace the card name in slave.pcm and control.card with the name of soundcard you use.

Re: SPI delay between bytes is different for small and large transfers (spidev)

Did you find a fix for this under spidev? I have the same issue, but see the delay with long buffers when calling writebytes or xfer/xfer2. There is no delay with buffers less than 0x10000 bytes in length, but I see a 1.5 bit time delay between bytes when buffers are 0x10000 byte in length or more....

Re: STICKY: The I2S sound thread.

Hmmm you seem to have an asoundrc in place that downmixes to mono. Also "-f cdr" is odd, usually you'd use "-f cd" which is S16_LE (-f cdr is S16_BE) - but I'm not sure if this has an effect when used with wav files (never tried that). I'd start by using speaker-test and outputting directly to the h...

Re: I2S clocks, GPCLK0

As there's no support in the RPi hardware you have to manage channel sync in software, by starting / stopping all relevant clocks just at the right moment. This can probably be fragile, especially if you pause a stream which will cause bcm2835 hardware to stop transferring data in the middle of a fr...

Yes, it works, we're using it in LibreELEC. Basically you just have to point CONFIG_INITRAMFS_SOURCE to a cpio file of your initramfs and set root=/dev/ram0 on the command line. Here's the link to the RPi2/3 kernel config we are using (INITRAMFS_SOURCE is filled in by the build scripts): https://git...

Basically any IR LED should work, they typically transmit at about 940-950nm wavelength so should work fine with IR receivers. The most important differences between the different IR LEDs are power and opening (vieweing) angle / directivity. So you'll probably have to test which one works best for y...

You can ignore the "spdif" name, despite their name the spdif receiver/transmitter codecs are just very generic drivers that don't do anything except allowing 16-24bit audio. They can be used for all ADCs/DACs that don't require any special configuration via I2C, SPI or GPIO pins. The important thin...
