Not sure if this belongs here on the rav1e repo (will move depending on where it should be).
[20:40] < jamrial> so rav1e_container_sequence_header() returns the first four bytes defined in that configuration box, but not the actual seq header obu? O_o
[20:40] < Daemon404> yeah
[20:40] < Daemon404> spec says 'zero or more'
[20:40] < Daemon404> i can fix it probably but that's what it does right now
[20:41] < jamrial> it would ideally include it, yeah. but also, it would be nice to have a function that simply returns the seq header alone
[20:45] < Daemon404> for what use case?
[20:48] < jamrial> right now, extradata within avcodec/avformat is raw obus only. those four bytes are generated by a muxer if required (mov, mkv/webm)
[20:48] < jamrial> but i guess it would be a matter of propagating the seq header without the first four bytes, so no need for a second function
[20:49] < Daemon404> hmm OK
[20:50] < Daemon404> i'll open an issue and see what people think
[20:50] < jamrial> just making that function return a seq header as part of the config OBUs would be enough to remove the extract_extradata bsf from the wrapper
[20:51] < Daemon404> OK
here an example of the problem.
It right now by default looks like
incdir=/usr/local/include/rav1e
I think it would be better if it was /usr/local/include, and have the library users include <rav1e/rav1e.h> instead in their project files. That way CFLAGS will not be bloated with extra unnecessary -I entries

Commit f699aa4
line 43: No alt-ref / invisible? Or "multiple" if bundled? Does it matter? I'm not sure.
line 85: Mention allocation maybe? Does instatiation imply allocation? I'm legitimately not sure.
line 88/98/etc: Are configs and contexts reference counted? It's really weird to "unref" a config or context to me... Don't you just free it? If they /are/ reference counted... to what end?
line 132: I assume this is a number that is set by the user and propagated through to RaFrame as
line 141: I know it's mentioned in the documentation for RaConfig, but it should probably have some comment.
line 156: Typo? Also shouldn't it be 0 == success, < 0 == fail?
line 160: comment needed
line 198: Typo, also mention "in bytes"?
line 210: What does this mean? I don't know what producing a frame from the encoding contexts means, or why it has to be "from the encoding context" instead of just allocated. Is it because it needs the state from the context to determine subsampling, etc.?

[16:58] < Daemon404> mostly comment related
[16:58] < Daemon404> no comments yet on what needs to be added, from me
[17:03] < lu_zero> could you link it to an issue please ? I'll format it later ^^

Somewhere in the last two days builds started to fail. See https://travis-ci.org/lu-zero/crav1e/builds
There is an open issue about it. And my minimalist solution landed.

variantI'd ask @dwbuiten to help on the Window part :)
There are a number of possible solutions, one requires rust-lang/cargo#2729 to be addressed, the other is to leverage meson or just write a simple Makefile
.

receive-send
loop similar to what is being used by the rav1e
cli right now.Once xiph/rav1e#1097 is implemented, it should be pretty straightforward to add.
The following headers are included in rav1e.h
, but not used:
stdarg.h
stdbool.h
Not sure if this is some weird artifact of cbindgen?
How can I create a static librav1e.a
on macOS?

Open questions
Am I doing something wrong? Thanks.
