[FFmpeg-user] PNG images to avi - transparency issue

[Gopi Nath]

Hello,

i am trying to convert png images to avi which is working fine, but the
video is not showing the background transparency (png images has)

this is what my statement
ffmpeg -r 30 -start_number 1 -f image2 -i "imagespath" -y -pix_fmt yuv420p
-q:v 1 "output.avi"

after reading from forum, i tried adding png codec
ffmpeg -r 30 -start_number 1 -f image2 -i "imagespath" -vcodec png -y
-pix_fmt yuv420p -q:v 1 "output.avi"

then it shows the error
Incompatible pixel format 'yuv420p' for codec 'png', auto-selecting format
'rgb24'

so, i removed pix_fmt, then it creates video with transparency, but i am
able to open this video ONLY in VLC player, not any other players supported
this codec
ffmpeg -r 30 -start_number 1 -f image2 -i "imagespath" -vcodec png -y -q:v
1 "output.avi"

please suggest me any working method.

Regards,
Gopi.
