Well I was finally able to get a test recording
The video is HEVC 4:2:2. Is it a broadcast feed?
Kodi cannot play any 4:2:2 streams with VAAPI hw decoding, it falls back to sw.
For whatever reason Kodi detects it as an interlaced stream but the video is progressive. It plays properly if deinterlacing is manually disabled.
This is a known issue. No fix as of yet.
Given that http streaming might work wouldn't the problem be TVHeadend or pvr.hts and not Kodi (ffmpeg building aside)
Some more discussion about that issue. HTTP streaming does indeed work and the affected HEVC streams work with VAAPI hw acceleration. However, those streams also work with HTSP + sw decode (VAAPI disabled).
Looks like this change is also needed
Support for that chip revision was added by this linux commit. Kernel 6.12.x does not include it.
Did you use the current version of cxd2878.c or the version from the initial commit?
Remove/comment out this -
.set_property = cxd2878_set_property,
.spi_read = cxd2878_spi_read,
.spi_write = cxd2878_spi_write,and this
static void cxd2878_spi_read(struct dvb_frontend *fe, struct ecp3_info *ecp3inf)
{
struct i2c_client *client = fe->demodulator_priv;
struct cxd2878_dev *dev = i2c_get_clientdata(client);
if (dev->config->read_properties)
dev->config->read_properties(client->adapter,ecp3inf->reg, &(ecp3inf->data));
return ;
}
static void cxd2878_spi_write(struct dvb_frontend *fe,struct ecp3_info *ecp3inf)
{
struct i2c_client *client = fe->demodulator_priv;
struct cxd2878_dev *dev = i2c_get_clientdata(client);
if (dev->config->write_properties)
dev->config->write_properties(client->adapter,ecp3inf->reg, ecp3inf->data);
return ;
}if it is possible to have TBS5530 working
Only if you build a custom LE image with the drivers for TBS5530.
no own IR, no CEC
There are better ways to make those boxes work with IR remotes. FLIRC USB is the most obvious one.
no HD auidio passthrough,
You mean this? Your NUC11PA does not have a native HDMI, as can be seen on that block diagram. You simply bought the wrong hardware.
no uhd via live tv
The only non-working live tv stream I have ever encountered is a HotBird 4K HLG test channel. I actually try to find a solution for that. It appear to be a bug in Kodi's VAAPI code.
I attached a kernel patch that should allow you to build LE image with TBS 5230 driver.
1. Set up LibreELEC build system.
2. Copy the patch to /packages/linux/patches/default
3. Edit /projects/Generic/linux/linux.x86_64.conf. Add the line
CONFIG_DVB_USB_TBS5230=m
4. Build the image.
My initial testing of OpenGL GBM x86 image looks good.
I PR'd a Kodi fix for HDR passthrough on OpenGL. Hopefully, it would be merged at some point.
It was not possible to build OpenGL without X11. I'm not sure if anything changed now.
Also, current Kodi master does not support HDR passthrough with OpenGL.
Finding a way to reproduce this "offline", without the need of the DVB hardware would be a good start. I have a sample HotBird UHD .ts file but I have no idea how to make it fail since it plays fine in file mode.
They suppossed to have same kernel (drivers).
No, they are not.
It works correctly with some ARM box (Coreelec) in the same AVR. So what gives?
CE does not use 12-bit for 4K/24. Intel does.
LE does not force full RGB. It is set by Intel driver in kernel.
What about our GPUs (via modetest), and Kodi itself (via the limited color range option)?
Forcing RGB full/limited is only needed in some special cases when you know what you are doing.
Kodi's color range setting seems broken. Has an effect only on GUI, at least on Generic.
