 2.  In WidgetRender, use QImage::Format_RGB32 and QImage::Format_ARGB32_Premultiplied image formats as much as possible. The following reasons:
     1.  Avoid most rendering directly to most of these formats using QPainter. Rendering is best optimized to the Format_RGB32  and Format_ARGB32_Premultiplied formats, and secondarily for rendering to the Format_RGB16, Format_RGBX8888,  Format_RGBA8888_Premultiplied, Format_RGBX64 and Format_RGBA64_Premultiplied formats.
 
-### `avformat_seek_file`, when the seek time point is less than the current time point, such as -5 seconds, -10 seconds, the seek does not reach the target time point
-
-#### One solution is: first`seek`to 0 seconds, then`seek`to the target time point.
-
-At this time, the seek of -5 seconds and -10 seconds works very well, much better than before. Before, sometimes it would be stuck at the current time point and could not seek to the target time point.

-formatCtx->seek(0);
