Personal opkg Package Repo + youtube-dl + ffmpeg

unique1984

It is really simple!

After compile process packages will be create in the source folder.

Full path -> source/bin/packages/mipsel_24kc

Just copy that folder to public domain and edit the /etc/opkg/distfeeds.conf
file proper way.

I build for myself it includes youtube-dl, ffmpeg, some video tools etc.

wget -qO- https://yasinkarabulak.com/omega2/packages/distfeeds.conf >> /etc/opkg/distfeeds.conf

	OR

nano /etc/opkg/distfeeds.conf

# below lines goes in to /etc/opkg/distfeeds.conf

FFMPEG video to bmp sequence on omega2

In your 'ffmpeg installed computer' convert some video to your display size. (If you try this part in the omega it will possibly kill you, "time issue - life time" )
ffmpeg -i some-video-file.mp4 -vf scale=320:240 scaled.avi
copy scaled.avi file to ffmpeg installed omega2 using flashdisk, scp etc.
then we are ready!

connect the console of omega2 and type the command (edit the directory for your side)
ffmpeg -i scaled.avi -pix_fmt rgb565 -r 1/1 seqtest/file%001d.bmp
in this code 1/1 means 1 frame per second, 25/1 25 frame per second, and so on. Omega2p can handle 12fps
