AVSampleBufferDisplayLayer with VTDecompressionSession
7 juillet 2016, par user1784317I’ve been struggling with AVSampleBufferDisplayLayer being really choppy with a lot of motion. When there was motion in my live stream, it would be come pixelated and half frozen with multiple frames displaying at once. However, once I added the following piece of code, everything was solved :
VTDecodeFrameFlags flags = kVTDecodeFrame_EnableAsynchronousDecompression
| kVTDecodeFrame_EnableTemporalProcessing;
VTDecodeInfoFlags flagOut;
VTDecompressionSessionDecodeFrame(decompressionSession, sampleBuffer, flags,
(void*)CFBridgingRetain(NULL), &flagOut);Note that I did create the decompression session before, but I don’t actually do anything in the callback. I am still calling enqueueSampleBuffer : on AVSampleBufferDisplayLayer and that is how the video is displayed on the screen.
Do you have to call VTDecompressionSessionDecodeFrame for AVSampleBufferDisplayLayer to display correctly ? I thought AVSampleBufferDisplayLayerr would use VTDecompressionSessionDecodeFrame internally. Is this due to being on the iOS Simulator ?

Is there a way to have a live website as an video overlay on RTSP stream using ffmpeg ? [closed]
29 janvier 2021, par user161284I'd need to have a live website on one corner of my RTSP video stream, which is then streamed to Youtube. I know I can do this with OBS, but the point is that nobody actually operates the computer, so I though I'd use ffmpeg.


I know that ffmpeg can add images as an overlay, but in my case the need would be to use a live website as the overlay. Whether this would be accomplished with "plain" ffmpeg or some other piece of (already existing) software in-between does not matter.


After reading the ffmpeg documentation and some earlier posts a few years ago, it unfortunately seems that there's no way to use html as an overlay with plain ffmpeg.


Any suggestions to overcome this challenge ?
