thanks @hiiamboris @dsunanda

@hiiamboris

maybe even
system/view/screens/1/size * system/view/metrics/dpi / 96 + 3 and complement 3

but this needs testing on nonstandard resolutions / dpis

@greggirwin

We need to make sure that's doc'd somewhere.

Hello, how can I write two correlation commands in one line, for example?

create -dir % test
change -dir % test

If they are separated, space is occupied, for example cmd
md test && cd test

hiiamboris

@hiiamboris

what have you tried?

@ams02468

I want to fit two commands in one line

hiiamboris

@hiiamboris

Red does not distinguish new line from space or tab.

@ams02468

ok thx @hiiamboris

Is there any example for how use the dll library like 7z in red?

hiiamboris

@hiiamboris

both red/red and red/community repos are full of examples

https://github.com/ldci/redCV/blob/master/docs/RedCV_Manual.pdf maybe smth here too

I was looking for a link to your Red/System introduction, but haven't found it, so posted random one

I'm trying to take a script that converts 4K MP4 video from my Sony RX10 iii camera to a format editable by Davinci Resolve. For testing, I have the script print the string before it calls it. If i manually copy that string direct to the command line it works perfectly. But when the script calls it, it makes a video from just one frame. How call I correct this? Here's the script:

red []
f: request-file
str: to-string mold f
in-str: trim/with str "%"
out-str: copy in-str
replace out-str "MP4" "mov"
print out-str
ffm-str: rejoin ["ffmpeg -i " in-str " -c:v dnxhd -profile:v dnxhr_hq -pix_fmt yuv422p -c:a pcm_s16le -f mov " out-str]
print ffm-str
call/wait ffm-str
quit

hiiamboris

@hiiamboris

see if print outputs the correct string, minding the quotes

laturk

@laturk

hiiamboris, it does.

hiiamboris

@hiiamboris

no idea

Gregg Irwin

@greggirwin

@qtxie, any ideas? @laturk have you tried with /shell or /show? I know R2 had some issues in later releases if /show wasn't used. I haven't tried FFMPEG from Red though.

hiiamboris

@hiiamboris

it's possible that Red calls 32-bit version of ffmpeg, with 32-bit codecs, and those have some bugs resulting in this

if it's windows we're talking about

also ensure you're using latest, not stable, build

laturk

@laturk

Greg, using /shell or /show doesn't help.

Gregg Irwin

@greggirwin

OK, thanks for trying and reporting back.

laturk

@laturk

hihambrois, I think you are probably right that it is a codec problem.

I'm using archlinux, not windows. The build of red I'm using is about a week old.

Is there any way to make the resulting file overwrite the existing file?

hiiamboris

@hiiamboris

that's up to ffmpeg

laturk

@laturk

hiiamboris, yes, I just needed to add the -y option to ffmpeg. I should have realized that.

I don't understand how red can call the wrong codecs though.

laturk

@laturk

I can upload a short video file if anyone would like see what is happening. It is only a few seconds long, but still 74.3 MB.

hiiamboris

@hiiamboris

I've no idea how it works in linux under the hood, but since Red is using 32-bit libraries, it's possible that it's child processes are using those libs too, and that those are buggy.

@cloutiy

Red needs some tweeters. I can try to get the ball started if there is any interest.

laturk

@laturk

Will red eventually be using 64-bit libraries. 32-bit is pretty well a thing of the past.

hiiamboris

@hiiamboris

eventually yes

laturk

@laturk

Rebol view no longer works for me. I get: User Error: Bad face in screen pane! Near: size-text self

laturk

@laturk

Does "eventually" mean any time soon?

hiiamboris

@hiiamboris

Unlikely.

laturk

@laturk

hiiambrois, I was afraid of that. Thanks for replying.

dsunanda

@dsunanda

@laturk If Red is somehow calling the wrong version of ffmpeg, you may be able to bypass that by writing a short shell script to call ffmpeg, and then CALLing that from within Red.

laturk

@laturk

dsunanda, thanks, but I only have one version of ffmpeg installed, and even if I call it using its full path the result is the same.

laturk

@laturk

Success. Use call/console, and it works.
