# NOTES: "-vcodec" and "-acodec" can be changed to preferred stream types, e.g. libx264 and libfaac, respectively

# TODO: needs further investigation on segmentation accuracy; cutting may still happen on i-frames due to keyframe-level accuracy, but this may have been solved by mpegts-to-mp4 transcoding
