[Interest] QAbstractVideoSurface, QMediaPlayer, QVideoFrame

[Nuno Santos]

Hi,

I have extended QAbstractVideoSurface. I want to be able to process input frames from a video and process them in the original format of the video.

For testing purposes I have generated a video using the ffmpeg command:


ffmpeg -f lavfi -i rgbtestsrc -pix_fmt yuv420p -t 60 rgbtestsrc.mp4


This command generates 60 secs of video with a rgb test source and makes the frames in the pixel format yuv420p

I’m opening this video with QMediaPlayer and setting the video surface I have created to the media player.

On present I’m receiving the video frames but these are as follow:


QVideoFrame(QSize(320, 240), Format_ARGB32, NoHandle, NotMapped, [no timestamp])


I was expecting to have the frames in Format_YUV420P format. 

Is there anyway of getting the original frames of the video without them to be converted to ARGB32?


Thanks!

Nuno
