how to convert flv to divx in order to play in a dvdplayer

[bfa1trung]

Someone can help please, this following command didn't work:

ffmpeg -i "blessing 14_8_2015_v1.flv" -vcodec mpeg4 -b:a 200000 -s 853x480 -vtag DX50 -ar 44100 -ab 128 -ac 2 -acodec mp3 -vol 100 "Output.divx"

result :

[NULL @ 0000000002929980] Unable to find a suitable output format for 'Output.divx'
Output.divx: Invalid argument

Replace "output.divx" with "output.AVI".

Also: -s 853x480 is not acceptable, use either 852x480 or 854x480.

AFAIR, the built-in MPEG4 codec of ffmpeg is very sucky, and unless things have changed lately,
you should choose libxvid instead.

Neither of those resolutions is optimal. Encoders/decoders usually work with mod16 or mod8 pixel blocks.
848x480 is both mod16 and mod8.
856x480 would be mod8 only.

852x480 is mod4 or mod2.
854x480 is mod2 only.

"Optimal" or not, they do work.
Decent encoders know how to deal with mod4 and mod2 frame dimensions.
Decent decoders know how to discard the junk used for filling in the 8x8 or 16x16 blocks.
AFAIK, only the MPEG-1 and MPEG-2 encoders are forever bound to the 8x8-block restriction.

Ooops, I hadn't noticed that detail

If your hardware is 'ancient', then you can't use anything above 720x576, IIRC.
I stopped using standalone DVD-players years ago, this is the reason why I don't care about
mod16, maximum bitrates, etc Etc ETC, anymore.

Yes. And don't use mod2.

[bfa1trung]

so do 848x480 over pass 720x576 ? should I set it to 720x480?

[Detmek]

Yes, it does. 720x576@25fps are maximum width and height for PAL standard and 720x480@29,97fps are maximum width and height for NTSC standard. If your original intent was to encode in 854x480 resolution you should use 720x400 for mod 16 and to keep aspect ratio.
