Sorry for late response! Thanks for reporting this issue.
First, the snap doesn't support hardware acceleration, as you could see in logs: MediaPlayer Uses software decoding
. The switch to enable / disable is not doing anything in this case: I took note that it should just be disabled to avoid confusion.
Second, it seems you have hardware decoding available with the compiled version (0.7.3) ; MediaPlayer Uses vaapidecodebin decoding
However indeed, logs are surprising as you have both success messages MediaPlayer 674084088962751893 Opened 'video.mp4'
and error messages Warning - 'file:///.../video.mp4': Internal data stream error
.
It could indeed thus be a problem internal to gstreamer. The error message from vaapisink is indeed indicating such unavailability of vaapi ...
A decoding pipeline to test could look like this (I can't try here without vaapi hardware, but you see the logic) :
gst-launch-1.0 filesrc location=/Users/path/Video.mp4 \
! qtdemux \
! vaapidecodebin ! videoconvert ! videoscale ! autovideosink
if again the Internal data stream error
occurs, I am afraid its a question of gstreamer and drivers...
aha, I forgot to say : i switched to packaging with Flatpak to overcomes this limitation of snap.
You can try with the published package or to create a custom flatpak
gst-launch-1.0 filesrc location=~/Videos/test.mp4 \
! qtdemux \
! vaapidecodebin ! videoconvert ! videoscale ! autovideosink

Video plays but is entirely black. Hrm.
Flatpak loads and plays videos, both with and without hardware acceleration, although it looks like hw accel isn't actually working? Here is the log from the flatpack with hw accel on:

Maybe flatpak doesn't have the vaapi gstreamer plugins?
Also fps with 1 video playing performance is 42 fps and 35fps with 2 videos playing. In the compiled vimix with no accel I got 29 fps with same 2 videos. ¯\_(ツ)_/¯
Sidenote: get a repeating message on the cli when running the flatpak and opening a file:
(vimix:2): GVFS-WARNING **: 15:07:26.173: The peer-to-peer connection failed: Error when getting information for file “/run/user/1000/gvfsd”: No such file or directory. Falling back to the session bus. Your application is probably missing --filesystem=xdg-run/gvfsd privileges.
On cli I also get this error in the compiled version:
0:00:00.449680510 11717 0x7f6268007860 ERROR vaapivideomemory gstvaapivideomemory.c:254:map_vaapi_memory: failed to make image current

So I'm pretty sure this is some weird gsteamer vaapi issue, and I took a look through gstreamer issues and there are some vaapi related ones there but nothing that seems exactly the same. I can live with software rendering for now!
The installation of gstreamer and its modules is always delicate indeed...
Thanks to your input, I noticed now that the Flatpack rules for compiling gstreamer might forget vaapi: I will investigate.
Now, regarding performance and use of vaapi, its all on gstreamer (vimix launches and controls pipelines, but is limited in what to ask to gstreamer). An honest but sad conclusion of all your tests is that your system and gst do not support vaapi correctly...
PS: I use a machine with nvidia GPU and must admit that on this the drivers are very well optimized.
Since version 0.8.0, the Flatpak compilation includes the vaapi module of gstreamer.
Please try with the flatpak of version 0.8.0 and let me know if this solved the decoding problem.
The flatpack is working with hardware decoding turned on (and off)! Thanks! Fps is mostly 60 too. No errors on command line, although I got a bunch on shutdown after switch from software to hardware decode (only the first time, couldn't replicate).

For completeness here are the errors on shutdown first time switching software decode to hardware:

Thanks for your confirmation! Glad that the vaapi is detected with the Flatpak !
I may have made some progress on this! I found some videos that open in the latest 0.8.0 self compiled version (with hardware acceleration on) and was able to compare to videos that don't work. The consistent difference is the colorspace:
Not working:
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'black_2s.mp4':
Metadata:
major_brand : isom
minor_version : 512
compatible_brands: isomiso2avc1mp41
encoder : Lavf59.16.100
Duration: 00:00:02.01, start: 0.000000, bitrate: 42 kb/s
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p(tv, bt709), 1920x1080 [SAR 1:1 DAR 16:9], 25 kb/s, 30 fps, 30 tbr, 15360 tbn, 60 tbc (default)
While working videos all have yuv420p(tv, smpte170m)
(but everything else the same).
I tried converting a non-working video to a working one, but that didn't resolve the issue, so that is very strange.
ffmpeg -i bt709_colorspace.mp4 -color_primaries smpte170m -color_trc smpte170m -colorspace smpte170m smpte_colorspace.mp4
Also tried creating a smpte240m colorspace in kdenlive and that also doesn't load.
Tried converting to different video formats, mov
didn't work, but webp
did load but the colors were damaged. HEVC
did work even with bt709 colorspace! As did converting to avi
(which seems to not know the colorspace and uses software decoding?)
ffmpeg -i input.mp4 -c:v libx265 -vtag hvc1 -c:a copy test_hevc.mp4
Not sure if there is anything in vimix that might account for that? I can try converting everything to hevc for now.
Having two different but potentially linked issues on a Ubuntu 22.04 machine with Intel CPU and graphics.
1) The snap (0.7.1) has black only output window (with both hardware accelerated and not). Says Gstreamer 1.14.05 in About. 2) Compiled latest (0.7.3), which has working output window but only loads videos (only tested mp4 so far) when no hardware acceleration used. Says GStreamer 1.20.03 in About.
It is quite likely that none of this has to do with vimix?
So for the compiled build: everything went fine. Videos refuse to load if hardware acceleration is on, log says:
I don't know much about vaapi or gstreamer but took a look at https://lifestyletransfer.com/how-to-install-gstreamer-vaapi-plugins-on-ubuntu/ and tried some of the things there. Everything seems to be installed ok.
Log from snap version (same video loading fine, but no output):
Here is an example videotestsrc that also fails:
