22 * To create a simple file for smooth streaming:
23 * avconv <normal input/transcoding options> -movflags frag_keyframe foo.ismv
24 * ismindex -n foo foo.ismv
25 * This step creates foo.ism and foo.ismc that is required by IIS for
26 * serving it.
27 *
28 * To pre-split files for serving as static files by a web server without
29 * any extra server support, create the ismv file as above, and split it:
30 * ismindex -split foo.ismv
31 * This step creates a file Manifest and directories QualityLevel(...),
32 * that can be read directly by a smooth streaming player.
