I have written following code to add generated audio into a silent video. It executes smoothly. But the audio doesn't get added into the "newvideo.avi" file.
videoFReader = vision.VideoFileReader('silent_pgwl1s.avi');
% videoFWriter = vision.VideoFileWriter('newvideo.avi','AudioInputPort',true);
videoFWriter = vision.VideoFileWriter('newvideo.avi','AudioInputPort',true);
for i=1:75
% videoFrame = step(videoFReader);
% step(videoFWriter, videoFrame,predgwo);
videoFrame= step(videoFReader);
videoFWriter(videoFrame,orgvf) ;
end
release(videoFReader);
release(videoFWriter);
