[FFmpeg-user] support for .oga and .ogx formats? (sort of feature request)

[roger21]

hello,

i'm surprised the .oga format is not supported while the .ogv is, and
they both seems to be aliases to .ogg anyway

since .oga is the official extension of the audio/ogg MIME type (just
like .ogv is the official extension for the video/ogg MIME type) it
would be nice to have both https://wiki.xiph.org/MIMETypesCodecs

i understand .ogx could be a bit more complicated since the format seems
more featured

so my question would be, is there an explanation, is it experimental, is
it so lame that nobody care anyway?

thanks

why do you think so?
you tell ffmpeg with params what it should do

-f ogg -acodec vorbis -strict experimental"
-f ogg -acodec libvorbis

(I don't think so, after all we support muxing ogg
files which is exactly - 100% - the same.)

Yes, I think so.

Anyway, patch for .oga sent.

ok so i saw that "oga" is now a format in the "ffmpeg -formats" list and
that is nice

but now i am confused, i said the "ogv" format is supported because i
made an "ogv" file just by using the ".ogv" extension (and yes it made
something quite identical to ogg and it was ok for me - and it still
works) but i actually have two issues about that now:

first, i tried to fake an "ogx" file into an "ogv" file using the "-f
ogv" parameter and it didn't work because it didn't know what that "ogv"
format was (i eventually used -f ogg instead)

without "-f":

[NULL @ 02df8020] Unable to find a suitable output format for
'video.ogx.theora.vorbis.c.c.ogx'
video.ogx.theora.vorbis.c.c.ogx: Invalid argument

with "-f ogv":

[NULL @ 02df8020] Requested output format 'ogv' is not a suitable output
format
video.ogx.theora.vorbis.c.c.ogx: Invalid argument

and then, "ogv" is not in the format list (as "oga" is now)

so i was thinking "ogv" is a sloppy clone, not in the list, not usable
with "-f" ... but as i see it now for "oga" (wich is a total clone) all
of that is false, it is in the list and i can use it with "-f" ...

so at the end i don't understand what is "ogv" for ffmpeg and shouldn't
it be usable just as "oga" now or does "oga" have to much privileges now?

(yes, confused)

why don't you read your replies?
"ogv" is not a format "ogg" is one

ffmpeg -i test.mp3 -f ogg -acodec vorbis -strict experimental test.oga
Output #0, ogg, to 'test.oga':

ogv is the same and works at least the last 4 or 5 years with libtheora / libvorbis

-f ogg -vcodec libtheora -acodec vorbis -strict experimental
-f ogg -vcodec libtheora -acodec libvorbis

"-acodec vorbis -strict experimental" in case you don't have linked "libvorbis"

There is no format named "ogv" in libavformat / FFmpeg.
And since the name of the format is - unlike the
file extension - defined and only used within
FFmpeg and its users, it is very unlikely that we
change it: It would "confuse" users (actually anger
them).

Please don't top-post here, it is considered rude.
