That's an odd interpretation of a news entry consisting on very few, very
clear paragraphs, and ending with a sentence that goes completely against

<@wbs> I don't think it's still "fixed" in the sense that ffserver and ffmpeg can be built from differing major versions
<@wbs> since it sends literal enum values over the wire, and those enum values are free to be changed at any major bump
<@wbs> and also, it doesn't even specify which major version it is talking about in the protocol
<@wbs> so api-wise it might be "fixed"; design wise, not yet
<+wm4> so my question would be does ffserver always use ffm for input/output, require it only for one of them, or is it completely optional?
<@wbs> wm4: afaik both ffmpeg and ffserver uses ffm, so if ffmpeg were to be able to communicate with ffserver, it needs an ffm demuxer/muxer as well
<@wbs> wm4: and it's all pretty backwards compare to most other protocols; if ffmpeg is to send data to ffserver, ffserver first tells it what codecs and encoder parameters to use, and then switches(?) communication direction to ffmpeg sending, ffserver receiving
<@wbs> all of this is custom code in ffmpeg.c ofc
<+wm4> lol really?
<+wm4> so ffmpeg.c has explicit ffserver handling, outside of the ffm libavformat parts?
<@wbs> see ffmpeg_opt.c, read_ffserver_streams etc
<@wbs> was the first I found with a quick grep
<@wbs> so yes, it no longer uses deprecated api (avstream->avcodeccontext), but it still uses a bunch of networking internals from lavf, and the design is buried deep in ffmpeg
<+wm4> just looked at ffserver.c
<+wm4> #include "libavformat/avio_internal.h"
<+wm4> even #include "libavformat/internal.h"
<@wbs> and it uses a bunch of internal rtp/udp functions that don't fit in in the normal avio/urlprotocol api
<@wbs> so it's not "fixed" yet. one of the deprecated details in codecpar might be worked around
Also, the part about "confusing configuration file syntax", but i guess that
can be considered subjective.

Saying you and Nicolas are ignoring events (or rewriting history) to support you
position on this subject is not name calling.
And i suggest you go hunt instead the people that actually called others names.
I pointed them to you in a previous email.
