Creating stories out of a long video:

.makeVid FILE_NAME 00:00.0 -> 01:00.0
OR

ffmpeg -sn -hide_banner -loglevel error -ss 00:00.0 -to 01:00.0 -i Fate-Royalty.mp4 -vf "scale='min(iw,1280)':'min(ih,720)'" -pix_fmt yuv420p -c:v hevc_nvenc "part1.mp4" -y

Then:

.sh ffmpeg -i part1.mp4 -vf 'split[original][copy];[copy]scale=-1:ih*(16/9)*(16/9),crop=w=ih*9/16,gblur=sigma=20[blurred];[blurred][original]overlay=(main_w-overlay_w)/2:(main_h-overlay_h)/2' -c:v libx264 -crf 20 out1.mp4 -hide_banner -loglevel error -y

Then:

.sh ffmpeg -i out1.mp4 -vf "scale='min(iw,1280)':'min(ih,720)'" -c:v libx264 out1final.mp4 -hide_banner -loglevel error -y

Then:

.eval await user.send_story('out1final.mp4', privacy='all', pinned=True)

Do It by Code

Generating a PEM format RSA private/public key:

openssl genrsa -out elot-privatekey01.pem 2048
openssl rsa -pubout -in elot-privatekey01.pem -out elot-publickey01.pem

Exporting info about a PEM generated RSA private key:

$rsa = [System.Security.Cryptography.RSA]::Create()
$rsa.ImportFromPem((gc "path" -raw))
$rsa.ExportParameters(true)

Take note that parameters are in Big Endian. For Little Endian, use Array.Reverse on them.

Marvin Attack: potential key recovery through timing sidechannels

### Impact
Due to a non-constant-time implementation, information about the private key is leaked through timing information which is observable over the network. An attacker may be able to use th...

If you want ffmpeg to use your gpu, you have to use:

-c:v h264_nvenc
-c:v hevc_nvenc #for h.265
