  • KI Pro (S905D) Need to debug log run UART

    Plan A: afl1's current work forward-ports the legacy Amlogic/Android dvb approach using the kernel backporting technique (media_build). It works but some people (not me, but kernel maintainers whose opinions count) consider this approach to be inappropriate as the legacy Android approach does not follow kernel standards. It's not impossible for afl1 to adapt his code, but this will take some time and effort and will require persistence and a willingness to accept feedback. So far he has only submitted one small fragment of code to a kernel mailing list. That was back in January and the maintainers made comments which received zero response. If he has any interest in seeing his work upstreamed (and sending the patch would indicate that he does, or did) communications will need to improve. If afl1 needs help with the upstreaming or communications there are numerous people who would like to assist. All he needs to do is ask for help.

    Plan B: There are also funded commercial projects in the Amlogic ecosystem with requirements for mainline kernel DVB support so even if afl1 shows no further interest in sending code upstream; at some point a professional developer will be tasked to write and then upstream something that meets the required standards. This will not happen quickly as there are many code packages in those commercial projects with a higher-priority, but eventually it will be the top item on someone's to-do list and I am confident that it will be done.

    I'd personally like to see the work done by afl1 be adapted and absorbed for the benefit of all, but I also see dvb support as a minor feature. Our overall experience as a project shows that the majority of users prefer USB tuners or independent network-based tuner devices as they are client-device agnostic, usually deliver better results, and are better long-term investments.

  • Issues with network shares

    Two suggestions:

    a) locally mount the remote filesystem(s) via systemd mount files. This allows you to place a hard dependency on the local mount completing before the Kodi systemd target can start.

    b) manually update the library periodically after you add new content, not automatically on every boot.

  • Issues with RF Remote w/ IR Learning Feature (Odroid C2)

    ir-keytable needs to be listening on the right protocol to see anything and some remotes have odd vendor invented stuff for power-on events; for the same reason you might not be able to teach a remote that only understands specific protocols and doesn't just capture/record whatever signal is transmitted to it. I'm about to start playing around with the current official HK remote to ensure it works on mainline kernel images using mainline u-boot, but that's not an endorsement and might not be a quick solution.

  • Libreelec only in DHCP

    The connection manager (connman) stores static connection details against the MAC address, and if you investigate you'll probably discover that the kernel is assigning a random MAC address on each reboot, so there is no matching profile and it defaults to DHCP again. The cause is the hardware manufacturer being too cheap to spend some $$ getting a block of unique MAC addresses for their hardware. To advise a workaround we'll need to know what hardware you have?

  • Passtrough

    Users often and wrongly believe pass-through is some magic "hardware doesn't touch the bitstream" method, but in reality the hardware has to support the stream format to correctly detect and handle it as a pass-through stream. Raspberry Pi doesn't support any HD formats.

    Quote from noblock

    chewitt, now, when using the mainline kernel, everything is the same at the linux packages level between Allwinner and Amlogic. With one exception, the m2m cedrus and meson implementation are not compatible. Is there some standardization / merge in progress on that matter?

    The video pipelines for Amlogic, Raspberry Pi and Exynos have stateful decoders while Allwinner and Rockchip have stateless decoders. It's not possible to combine them into a single m2m implementation as stateful/stateless work in fundamentally different ways, although we are working to minimise the differences and have ffmpeg mask the implementations so there's still a single/common interface with Kodi. As there's no prior art for anything it's a "two steps forwards, one step backwards" kind of process, and there's still a ton of code to write, but the direction is still forwards, and each month ever more bits of the big jigsaw puzzle are falling into alignment.
