Deinterlacing with ffmpeg?

[jameswilson]

lol i found that too.
The only way to do it would be to capture the input with ffmpeg and then deinterlace it then give it to zm, how i dont know

Also the new hd std has 1080i so its still interlaced as it uses half the bandwidth of 1080p

720p would be the ideal resolution really as its progressive without too much bandwidth. There are lots of programs that would capture the input and de-interlace it but I dont think you could get proper status reports from it which is probably why a custom capture program was written.

With regards to the original question in this forum. While researching I found out if you want to de-interlace clips when exporting, ffmpeg wont do it (as you found out)

but mencoder will using the following command

Code: Select all

mencoder mf://filename.jpg -mf w=720:h=576:fps=10:type=jpg -vf lavcdeint -ovc lavc -lavcopts vcodec=mpeg4 -ofps 25 -oac copy -o output.avi

Where

filename.jpg = the jpg file you want to convert (can use *.jpg to convert an entire event)
w= width in pixels
h= height in pixels
fps = the fps rate of your camera
-vf lavcdeint is the deinterlacing filter (read the man as there are quite a few deinterlacing filters)

dunno if that helps but after a quick test I got a working video file of an event that was fully deinterlaced.

hi kdf... nice find! Exactly what I've been looking for.

Can you help a noob out though and show us all how you could integrate this function into zoneminder to replace the ffmpeg/mpeg_encode function?

Thanks heaps:)
