Video playback upside down #29

Closed pfeifel closed 7 years ago

pfeifel commented 7 years ago

I am sending video frames in VideoFormat.Rgb24_424x240_15Fps and they are played on the client upside down.

Any idea what could cause this?

Hey,

The RGB file you are trying to stream was probably generated with bottom-up DIB, meaning the frame starts with the bottom row of pixels. Can you please generate it with top-down DIB or change the format to YUV to avoid this issue, since DIBs in YUV formats are always top-down.
