gstreamer plugin failed to build in VS 2017

[dudulashok]

Please help me find the issue. Attached meson-log.txt file for your reference.

Hi @dudulashok , it seems that you didn't install svt header files. cmake -P SVT-HEVC\Build\Windows\Source\Lib\cmake_install.cmake. Pls make sure you follow the build steps. We will double check on our side. Btw gst plugin is upstreamed already. It's better to use this one. We plan to take down the gst plugin in this repo. https://gitlab.freedesktop.org/gstreamer/gst-plugins-bad/-/merge_requests/731?commit_id=663aeb2131a12d38a0729129ca8709645ca3afd5.

'EbApi.h' is part of API, not under Lib. I tried twice in my side, but got the same error.

[tianjunwork]

Yes, both header files and libs should be installed. I will try on my side.

[tianjunwork]

Fixed in the latest commit: cmake -P SVT-HEVC\Build\Windows\cmake_install.cmake

Thank you. It's working, but the below error is coming. (gst-inspect-1.0:8348): GStreamer-WARNING **: 02:59:13.376: Failed to load plugin 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\gstsvthevcenc.dll': 'C:\gstreamer\1.0\x86_64\lib\gstreamer-1.0\gstsvthevcenc.dll': The specified module could not be found. No such element or plugin 'svthevcenc'

gstreamer is unable to load the dlls. This may not be related to svt hevc, but any step missed in the readme doc?

[tianjunwork]

Did you install?

Then the plugin can be compiled and installed using Ninja:

meson -Dprefix=%GSTREAMER_1_0_ROOT_X86_64% build && ninja -C build && ninja -C build install

C:\Jun_Dev\SVT_OS\SVT-HEVC\gstreamer-plugin>meson -Dprefix=%GSTREAMER_1_0_ROOT_X86_64% build && ninja -C build && ninja -C build install
Directory already configured.

Just run your build command (e.g. ninja) and Meson will regenerate as necessary.
If ninja fails, run "ninja reconfigure" or "meson --reconfigure"
to force Meson to regenerate.

If build failures persist, run "meson setup --wipe" to rebuild from scratch
using the same options as passed when configuring the build.
To change option values, run "meson configure" instead.

Hi @tianjunwork Yes, I have installed and getting the logs same as yours. After that while verifying the installation using the command "gst-inspect-1.0 svthevcenc", it is showing "No such element or plugin "svthevcenc'". I think something is missing. I'm trying to find the issue, at the same time if you check in your side will be helpful.

[tianjunwork]

export GST_DEBUG_FILE=
export GST_DEBUG="*:6"

You can enable log to see what is going on. If the plugin is correctly installed, I never see this error before. May be related to your env.

[tianjunwork]

Hi @dudulashok, hope that gst plugin works on your side now. Any further assist needed?
