mkdemo-abr

Overview ¶

mkdemo-abr creates an ABR (Adaptive Bitrate) demo set from a source video. It uses ffmpeg to transcode to multiple bitrates, then encrypts each as v3 chunked SMSG.

Usage: mkdemo-abr <input-video> <output-dir> [password]

Output:

output-dir/manifest.json    - ABR manifest listing all variants
