Failure using Vapoursynth script as input, but piping same script through vspipe works #284
Description
Hi, I'm trying to use QSVEnc to encode a Dolby Vision profile 7 into profile 8. I'm using Vapoursynth along with FelBaker and BestSource plugins. This is the Vapursynth script:
import vapoursynth as vs
core = vs.core
core.max_cache_size = 4000
core.std.LoadPlugin(path="/usr/local/lib/vapoursynth/libfelbaker.so")
core.std.LoadPlugin(path="/usr/local/lib/vapoursynth/libbestsource.so")
bl = core.bs.VideoSource(source="/temp/Runner-0d27bb48-52f3-4184-87cd-886ed39d4e6b/bl.hevc", hwdevice="vaapi")
el = core.bs.VideoSource(source="/temp/Runner-0d27bb48-52f3-4184-87cd-886ed39d4e6b/el.hevc", hwdevice="vaapi")
if bl.num_frames != el.num_frames:
min_frames = min(bl.num_frames, el.num_frames)
bl = bl[:min_frames]
el = el[:min_frames]
clip = core.fel.Bake(bl, el)
clip = core.resize.Spline36(clip=clip, format=vs.YUV420P10, matrix_s="2020ncl", transfer_s="st2084", primaries_s="2020", range_s="limited", chromaloc_s="top_left", dither_type="ordered")
clip.set_output()
If I use this command:
/usr/bin/qsvencc
-i /temp/Runner-0d27bb48-52f3-4184-87cd-886ed39d4e6b/script.vpy
--codec hevc

--frames 170905
--fps 23.976
--async-depth 8
-o /downloads/temp/baked_p8.mkv
It outputs this:
[failed to initialize file reader(s).
[libva info: VA-API version 1.20.0
libva info: Trying to open /usr/lib/x86_64-linux-gnu/dri/iHD_drv_video.so

However, if I run the command like this:
vspipe
-c y4m
'/temp/Runner-0d27bb48-52f3-4184-87cd-886ed39d4e6b/script.vpy' - |

-o '/downloads/temp/baked_p8.mkv'
It works correctly. Since the VS script itself works, I want to skip vspipe as it adds overhead to the script. What could be the issue?
