windows平台编译后，python使用提示缺失c_ffmpeg_decoder模块

[x850044053wwt]

大佬们好

按照文档指引，我在windows平台上完成了编译。然后按照colab上的example 尝试执行https://colab.research.google.com/github/BabitMF/bmf/blob/master/bmf/demo/edit/bmf_edit_python.ipynb#scrollTo=vM3JZjmXHO-k

# encode ( bmf.encode(concat_streams[0], concat_streams[1], { "output_path": output_path, "video_params": { "width": 1280, "height": 720, 'codec': 'h264' } }).run() )

时我的python提示我

RuntimeError: ModuleNotFoundError: No module named 'c_ffmpeg_decoder'

请问下是哪里出了问题

Have you downloaded the bmf package in Python？plz make sure the package you compiled is in the Python environment

由于网络原因，我无法在我的windows电脑上的python安装bmf。因此我是基于源码编译，然后在python中使用的。bmf包已经在我的python环境中，但是缺少了c_ffmpeg模块

[JackLau1222]

you can copy these complied files into your python environment. If you use conda, the path is ~/.conda/envs//lib, and make sure the FFMPEG is enabled so that the c_ffmpeg_decoder can be built

[JackLau1222]

bmf_builtin_module.so(c_ffmpeg_decoder and other modules) is compiled and output in /output/bmf/lib, please check it

[x850044053wwt]

bmf_builtin_module.so(c_ffmpeg_decoder and other modules) is compiled and output in /output/bmf/lib, please check it

我是windows平台编译，应该是bmf_builtin_module.dll这个lib吗，我没有找到

yes, the c_ffmpeg_decoder module is built into bmf_builtin_module.dll, plz check log when you execute build.sh and make sure the BMF Summary contains FFMPEG_ENABLED : ON

是的，编译时summary是ON

OK, it seems that this is not the problem here. Please check whether libbuiltin_modules.so is built in the log.

我刚检查了编译过程，这个模块编译失败了，原因是用到了AVStream的codec成员，但是在我的ffmpeg5.1.2版本中，这个成员已经废弃了。这是否是一个bug

Good job! This seems to be a compatibility issue. We will fix this issue later. If you are interested, you are also welcome to submit a PR after the fix.
