Hello,
I have converted UIImage
to CVPixelBuffer
. I am creating a video writing app. In some cases, the same CVPixelBuffer
should last in the video for 2 seconds or more.
However, I need to add 30 CVPixelBuffer
s per second because the video, to work on social media, must be 30 frames per second.
The problem is that whenever I try to add frames to long videos, like 50-minute videos, it gives an error.
The error is something like "Operation cannot be completed".
Give me an example of a loop to add 30 CVPixelBuffer
s per second to a currently written video.
Example:
while true {
if videoInput.isReadyForMoreMediaData {
break
}
if videoInput.isReadyForMoreMediaData,
let buffer = videoProvider.getNextFrame() {
adaptor.append(buffer, withPresentationTime: CMTime(value: 1, timescale: 30))
}
}
I await your response.
