Re: [rtcweb] Straw Poll on Video Codec Alternatives

[Daniel-Constantin Mierla <[e-mail]>]

1. All entities MUST support H.264
   a. Are you in favor of this option [Yes/No/Acceptable]: *No*
   b. Do you have any objections to this option, if so please summarize 
them:
*Too many IPR issues and licensing constraints that makes its usage 
effectively impossible in a lot of cases****. It has royalty fees (some 
known, but many unknown) -- imposing a financial revenue from 
implementers/users towards various companies via Internet/IEFT standards 
is beyond common sense, openness for everyone and target for innovation 
that governed Internet evolution so far. Full hardware H.264 
encoders/decoders don't really exist at scale, especially on exiting 
mobile devices where it would be relevant, or at least not exposed to 
any third parties -- expecting that some vendors will do it is 
comparable with expecting all claims of VP8 IPR will be dismissed.

   a. Are you in favor of this option [Yes/No/Acceptable]: *No*

   a. Are you in favor of this option [Yes/No/Acceptable]: *No*
   b. Do you have any objections to this option, if so please summarize 
them:
*No if there are risks on**H.263 IPR/licensing***not to be royalty free
