>>It shouldn't matter where the libva is built, only where it is
installed, which is usr/lib/$ARCH_TRIPLET/.
What you said is correct. (I did not make a clear expression.)
In post #110
./autogen.sh --prefix=/usr <<== give the install path so driver
will search from this path.
I build libva in my notebook. if not using --prefix=/usr will cause
other library loading problem.
Use this prefix will solve uncertainty.
It is just keep the same as apt install libva-dev.

Title:
[snap] vaapi chromium no video hardware decoding
Status in chromium-browser package in Ubuntu:
In Progress
Bug description:
To test the snap with VA-API changes,
1. Install the snap with
sudo snap install --channel candidate/hwacc chromium
2. snap run chromium --disable-features=UseChromeOSDirectVideoDecoder
--enable-features=VaapiVideoDecoder
3. Open a video, e.g. one from https://github.com/chthomos/video-
media-samples
4. Enter about:media-internals in the address bar and note what the
page says for kVideoDecoderName.
Please report
- The value for kVideoDecoderName from step 4. Success is typically
{Vaapi,VDA,Mojo}VideoDecoder while failure is {FFMpeg,Vpx}VideoDecoder;
- If failed, the video used for testing, including codec and resolution if
possible;
- Distro version (if in doubt, `grep VERSION= /etc/os_release`);
- GPU (if in doubt, attach the output of `lscpu`);
- CPU generation (if in doubt, attach the output of `lscpu`).
About the last point, it may be that unfortunately only those with
newer generations of Intel CPUs will have luck with this, but it's
still an uncertainty. So reports are highly welcome.
