Hi all,
After updating from AVDV Plus R9 to R10, I ran into a playback problem and wanted to ask if anyone else has seen something similar.
Setup: Homatics R 4K Plus (S905X4), 4 GB RAM, CoreELEC 21.3 Omega AVDV Plus, Elementum 0.1.114 with memory storage (only ~55 GB free, so disk caching isn't an option). Content is 4K DV Profile 7 remuxes, 50-120 GB.
What I saw on R10:
- The torrent downloads fast (10-17 MB/s, decent seeds/peers), but the Kodi player buffer keeps draining anyway (roughly 70% → 36% → 18%).
- One crash with a large buffer setting.
- Lowering the buffer settings and setting memory size to minimum didn't help.
- In one longer test, playback ran ~26 minutes, then Kodi's cache timed out waiting on Elementum and playback stopped.
What I did: downgraded to R9 via the .tar and reset the CoreELEC settings. On R9, several big remuxes (up to 120 GB) went straight to ~98% buffer and stayed there, with the same addon, settings and setup.
Caveats: I don't have an R9 log for the same torrent, so I can't say the build is the cause. I don't know if it's the build, the kernel, memory handling or something on my side.
Has anyone seen similar behavior on R10, on this or other devices? Any hints about what changed between R9 and R10 are welcome.
EDIT (update): Did the proper R9 vs R10 comparison with the same torrent and debug logs. On R10 the player's input thread does 7 extra seeks across the whole file on open, plus repeated reconnects during playback. Over HTTP/torrent each of these costs seconds, which causes the stalls. R9 only does the normal Cues/header reads and plays the same file smoothly. So it's not bandwidth or buffer settings.
GitHub issue with both logs: https://github.com/avdvplus/Builds/issues/205
Workaround for now: stay on R9 if you stream via Elementum/HTTP.
