Why is there a second scale that has no arguments?

And on a CPU that old, software scaling just isn't very fast

Well, that first scale filter still looks just as pointless

could be a bug in Jellyfin, but the second scale still applies to [0:2] right ?

Hey, I just sent my first patch to the llvm-devel mailing list like 4 hours ago and I don't see it in the archive--did I do something wrong? I've subscribed to the list and made sure it's plaintext only.
20:21
<
BtbN >
Why would we know about that list here?

ah, just read the title, probably should ask in #ffmpeg-devel, yeah?
20:25

you must send it from the exact address that's subscribed

I see, the verificaiton email went to spam--going to send again now that I'm properly subscribed

is there a way to figure out the name of the app or stream from the listener side of rtmp? specifically, if I `avformat_open_input` the url `rtmp://0.0.0.0:1234`, with the `listen` option set, and I connect to that with `rtmp://123.45.67.89:1234/foo/bar`, can I then get either `foo` or `bar` from the `AVFormatContext` somehow?

i have an mp4 file that is about 370MB. i tried extracting the audio to an m4a file. but the result is 170MB
21:39
<
johnjaye >
i have a tough time believing the audio makes of half of a file. am i doing something wrong here?
21:39
<
johnjaye >
i tried different variations of ffmpeg -i file.mp4 myfile.m4a with -vn and -c:a copy but same result

How are we supposed to decide if you do something wrong, when you don't show your exact commandline?
21:51
<
johnjaye >
i just did
21:52
<
johnjaye >
the last one i tried was ffmpeg -i file.mp4 -vn output.m4a
21:53
<
johnjaye >
unless i'm missing something and audio really just is that big somehow?
21:55
<
BtbN >
for one, that'll pointlessly re-encode the audio
21:55
<
BtbN >
and -vn will exclude all video, so whatever is left is actually that big
21:56
<
johnjaye >
i thought maybe the -c:a copy would make it not reencode the audio
21:56
<
johnjaye >
yikes. ok.
21:56
<
BtbN >
that only tells it to copy the audio
21:56
<
BtbN >
not re-encode it
21:56
<
BtbN >
It tells it nothing about the video, so the defaults for that still apply
21:57
<
johnjaye >
i guess it is a long file. 3 hours. what would 1 hour at 128 kb/s be?
21:59
<
another| >
ffmpeg -i input.mp4 -map 0:a -c copy out.m4a
22:00
<
johnjaye >
hmm. the math checks out. i guess maybe there is something wrong with the video then

128kb/s is roughly 1MB/min
22:01
<
johnjaye >
another|: yes that came out to 170MB or so
22:01
<
johnjaye >
i'm missing something here. why was that instant?
22:01
<
johnjaye >
does -c:a copy make it reencode the video?
22:02
<
another| >
It says nothing about video
22:03
<
johnjaye >
maybe without -c copy it reencodes the audio?
22:04
<
johnjaye >
i thought -c:a copy would do that
22:04
<
another| >
that is the default, yes
22:04
<
another| >
do what?
22:04
<
BtbN >
it tells it to copy all audio streams without re-encoding
22:04
<
johnjaye >
i thought -c:a copy would do the same as what you had
22:04
<
johnjaye >
but it's not
22:04
<
BtbN >
it tells it literally nothing about all non-audio streams.
22:05
<
johnjaye >
meaning what? it's reencoding the video stream and then discarding it since the output is an audio file?
22:06
<
BtbN >
m4a is just mp4 with a different name
22:06
<
another| >
this is getting nowhere. Please talk in full cmd lines
22:06
<
BtbN >
so it'll probably just put it in there anyway
22:06
<
BtbN >
You have gotten all info you need twice now, so not sure what else to tell you
22:06
<
johnjaye >
m4a can have video streams?
22:07
<
johnjaye >
ok. that is not what i understood from searching it.
22:07
<
johnjaye >
it specifically said it was audio only
22:07
<
another| >
Who or what said that?
22:07
<
BtbN >
m4a is literally mp4, with a different file extension
22:08
<
BtbN >
like all the other m4* formats
22:08
<
another| >
technically, in ffmpeg it's a slightly different muxer
22:08
<
BtbN >
Yeah, it gets different defaults applied
22:08
<
johnjaye >
so if i do ffmpeg -i input.mp4 -vn -c:a copy out.m4a the operation takes a few seconds
22:08
<
BtbN >
but if there is a video stream, it will absolutely end up in there
22:08
<
johnjaye >
but without the -vn it takes about 5 minutes
22:08
<
BtbN >
yeah, that sounds about right
22:08
<
BtbN >
transcoding video is slow
22:08
<
kepstin >
i think in ffmpeg the m4a extension ('ipod' muxer) sets different brands in the isobmff container?
22:09
<
johnjaye >
indeed it is
22:09
<
johnjaye >
is there an audio only format i can use to force audio?
22:09
<
johnjaye >
i thought that's what i was accomplishing by using .m4a
22:09
<
another| >
kepstin: yes
22:09
<
kepstin >
if you only want audio, add mapping options to select only audio
22:10
<
BtbN >
you posted a perfectly fine commandline just now
22:10
<
johnjaye >
ok. i'll rely on -vn and -an then as opposed to the file format
22:11
<
BtbN >
you're gonna need that anyway, cause if you were to try to mux video to say .mp3, pretty sure you'd end up with an error
22:11
<
BtbN >
it won't just silently discard the video stream
22:12
<
another| >
It might also try do use it as cover art
22:12
<
johnjaye >
so i can't just mindlessly do ffmpeg -i myfile.mp4 <... options ...> file.mp3
22:12
<
BtbN >
Yeah, mp3 is a really messy non-format
22:12
<
BtbN >
it's pretty much just raw bitstream in a file
22:13
<
johnjaye >
is ogg technically better? i remember for awhile people were encoding video in .ogm
22:13
<
BtbN >
Theora is pretty much a dead codec
22:14
<
BtbN >
And using Vorbis is weird, when Opus exists

what is the dominant container format? just mp4* now?
22:18
<

depends on how you see it
22:18
<

mpegts, matroska via webm, mp4/mov
