In my app I processing video frames from quicktime movie, getting them with ci::qtime::MovieGlRef.
Is it possible to get audio data from audio tracks of movie within cinder to process and play them?
I’m not sure if you can extract the data from Cinder, but you can always use ffmpeg to process the video file to get the audio.
You mean Cinder-FFmpeg block?
I meant calling ffmpeg from the command line and extracting the audio to disk.
O! That’s unexpected.
I’ll keep this idea as last solution, if no other will be found.
But how to get it with cinder?
You run something like the following command with
ffmpeg -i video.mp4 -vn -acodec copy audio.mp4
