Building gstreamer from source in windows using ce

问题:

I am first time compiling gstreamer from source code and I am facing difficulty in building gst-libav-1.0 in windows.

I followed link given in the gstreamer website. only creation of .cerbero.cbc is avoided (as it gives lots more problems ,but default will work it say in site) compiling gstreamer from source code-- gstreamer website

ISSUES

1) After running build command I am getting error of

"/w32pthreads.h:137:1: error: unknown type name 'INIT_ONCE'" For more detailed error see error.txt file C:\Users\Admin\AppData\Local\Programs\Python\Python36\Python.exe ./cerbero-uninstalled buildone gst-libav-1.0

2) when I set the enable nvenc , cuda ...etc its showing :

configure: WAARNING: unrecognized options: --enable-hwaccels --enable-devices --enable-nvenc --enable-omx --enable-omx-rpi --enable-cuda --enable-cuvid --enable-libnpp --enable-ffmpeg

I have added above option in file "gst-libav-1.0.recipe" at below mentioned place

class Recipe(custom.GStreamer): 
    name = 'gst-libav-1.0' 
    # TODO - check license - plugin is certainly LGPLv2+, but need to check 
    #        the linked libs 
    licenses = [License.LGPLv2Plus] 
    config_sh = 'sh ./autogen.sh --noconfigure && ./configure' 
    configure_options = "--enable-lgpl --disable-examples --enable-static " 

How can I enable this option in the build of libav ?

Note: I have added logs generated while building

"Python.exe ./cerbero-uninstalled 
buildone gst-libav-1.0 "

a) gst-libav-1.0-compile.log gst-libav-1.0-compile.log

b) error.txt error.log

You have to use Python 2.7 to compile GStreamer - it looks like you're using Python3
