对于我的 PyQt5 项目,我使用的是 QWebEngineView
,但某些视频,例如 .mp4
视频无法播放.我可以使用 pip
安装编解码器,或者通过 QApplication()
或类似的方式传递某个参数来解决此问题吗?
For my PyQt5 project, I am using the QWebEngineView
, but certain videos, such as .mp4
videos won't play. Can I install the codecs with pip
, or pass a certain argument through QApplication()
or something similar in order to fix this problem?
我是通过pip
安装PyQt5的,所以我没有C:Qt...
文件,只有PyQt5
, pyqt5_tools
文件夹在 AppdataLocalProgramsPythonPython37Libsite-packages
.
I installed PyQt5 through pip
, so I don't have the C:Qt...
files, only the PyQt5
, pyqt5_tools
folders in AppdataLocalProgramsPythonPython37Libsite-packages
.
我正在使用 Python 3.7.2
和 PyQt5.11
pypi提供的pyqtwebengine没有开启use_proprietary_codecs
标志,所以无法播放.mp4.
The pyqtwebengine provided by pypi does not enable the use_proprietary_codecs
flag so you cannot play the .mp4.
如果你想获得一个播放 mp4 的 pyqtwebengine,你必须按照以下步骤操作:
If you want to get a pyqtwebengine that plays mp4 you must follow these steps:
您必须使用 WEBENGINE_CONFIG += use_proprietary_codecs
标志编译 Qt 以启用播放 mp4 所需的编解码器(Qt WebEngine功能:音视频编解码器)
You must compile Qt with the WEBENGINE_CONFIG += use_proprietary_codecs
flag to enable the codecs needed to play mp4(Qt WebEngine Features: Audio and Video Codecs)
然后使用那个Qt你必须编译pyqtwebengine.
Then using that Qt you must compile pyqtwebengine.
