michaelni: seems like a regression caused by rebase onto master, I'll investigate further when I'm done flying

(or possibly a bug fixed by a later commit in the two-part series)

ubitux: I'm probably missing sth but why is `ffprobe -show_packets -show_data` not an option?
<JEEB>
because you need to then parse that data out of the ffprobe output most likely
<ubitux>
yeah, i'm using binary tools down the line
<ubitux>
so i needed raw data
dellas has joined #ffmpeg-devel
<beastd>
Ah ok. The default output could be relatively easy parsed into separate files or whatever is needed e.g. with awk (could also transform the hexdump back into binary)
<beastd>
Could really be more convenient though
<ubitux>
-f data is just fine :)
<beastd>
hehe, the -f data weapon: passing through everything :)

Lynne: I know 4:4:4, 4:2:0, 4:2:2 and I think the DV one was 4:1:0... but I've not heard of 4:4:0 :D
<courmisch>
JEEB: 4:1:1
dellas has joined #ffmpeg-devel
dellas has quit [Remote host closed the connection]
<courmisch>
what even is 4:4:0? skipping UV on 3 out of 4 rows?
<JEEB>
right, 4:1:1
<courmisch>
so 4:4:0 is 90 degrees rotation of 4:1:1 ?
<jkqxz>
There is lots of 4:4:0 JPEG around. It's what you get when you rotate 4:2:2.
<JEEB>
ah

courmisch: 440 is the inverse of 422, vertical resolution is halved
<Lynne>
for chroma
<Lynne>
oh, that explain it
<Lynne>
though the image is a square album cover art, lol
<JEEB>
:D
<courmisch>
nonsensical naming convention
<courmisch>
how do you call square-rotated 4:1:1 ? 4:4:-2 ?
<nevcairiel>
technically you cant rotate 4:1:1 within the confines of those formats
<nevcairiel>
it does not allow for a quarter vertical resolution
