[FFmpeg-devel] Plans to support HLS-compatible AES-CBCS for MP4

[Toby Steele]

Hi There,

 

Looking at current MP4 encryption support, using the 'ffmpeg -h muxer=mp4'
command, I can see that only AES-CTR mode is supported. 

 

I was wondering whether there are plans to support AES-CBCS mode encryption
as well? This is needed to support CENC-compatible encrypted HLS content
using the fragmented MP4 container format, and so would be a very useful
addition.

 

Thanks in advance
