Very slow hardware decode using Intel iGPU with VAAPI
Closed this issue · 4 comments
I've tested this on two different systems (a laptop with an i7-8550U running Fedora 35 and an Intel NUC with i5 10210U with Pop OS 21.10).
On the laptop, running it through software rendering, I get ~15ms decode time, and it's very variable. If I enable the wayland socket, it switches to hardware decoding, and I get ~30ms decode time.
On the NUC, I can reproduce this, and I can also install the Parsec provided DEB. Here, same happens as on the laptop while running the flatpak, but when running the DEB directly, i get about 5-7ms decode time.
This is all for a 1080p60 stream from a LAN connected Windows host.
Is there a reason the flatpak version is so much slower with software rendering, and can that be fixed some way ?
Same with Fedora and Manjaro. VAAPI not working with Parsec Flatpak.
I tested with others Flatpak packages (like Clapper), VAAPI is working very well.
I have the same issue. In the logs I keep getting.
[I 2022-07-27 02:03:55] VAAPI: (1.7) Intel iHD driver for Intel(R) Gen Graphics - 20.1.1 ()
[D 2022-07-27 02:03:59] Decoder failure, queued_frames=62
Its also happening on the Parcec deb package.
Moonlight flatpak works great.
Parsec in itself doesn't currently support hardware decoding on Linux. They are intending to add it on the next release.
Parsec has not directly used libva for a long time now. With the rollout of 150-94, hardware decode will be restored in the form of FFMPEG 4, 5, and 6, hardware decode
