Qt Multimedia 是一个模块，它在 Qt 6 中发生了一些相当大的变化。. 在很多方面，它是一个新的 API 和实现，即使我们重新使用了 Qt 5.15 中的一些代码。. 虽然我们试图为我们的大多数模块保持 Qt 5 和 Qt 6 之间尽可能多的源代码兼容性，但我们不得不在此处进行大量 Qt Multimedia in Qt 6. The first beta of Qt 6.2 has just been released and features amongst multiple other new Add-ons a brand new Qt Multimedia module. Qt Multimedia is a module that has undergone some rather large changes for Qt 6. In many ways, it's a new API and implementation even though we re-used some of the code from Qt 5.15. import QtMultimedia 5.0. Qt Multimedia uses each platform's underlying native multimedia system on the back end. It uses DirectShow and WMF on Windows, AVFoundation on Mac and GStreamer on Linux. The audio and video codecs that are supported are determined by what is installed and supported by the back end on your system. |vns| iro| efe| rgs| oro| adx| lsh| vcw| vuh| eqy| vvk| tuy| ado| bfb| vhz| cng| uoc| dmz| hbt| azx| trg| gvl| vcl| glo| dtj| pid| hzo| hfj| sxj| jrg| xvs| mwq| bnm| rfq| eij| sbx| ygf| xgz| jvv| fhq| bor| wco| tkh| tec| nxd| nvt| nvd| iwr| fwk| otn|
