Re: [Elphel-support] broken files from footage?

2012-11-17 Thread flavio soares
No success here... =/

I uploaded two files to elphel's ftp (folder Videos). I used ffmpeg to
convert a mkv file to a series of jpegs. One of them is the jpg, the
other is just the jpg renamed to jp4. If I use elphel_dng to convert
them to dng, the colors shift completely. I can't seem to make
movie2dng work with them however...

Of all the scenes, this is the one I'd like to save the most. Any hints?

thanks again for all the help!

Flavio,

Looks like ffmpeg puts (at least) its own headers into the
files: JFIF Lavc52.123.0... - this causes the wrong conversion.

I don't know whether an *.mkv file has full frames inside (most likely it's
not)

If it does then
split_mov_2.phphttp://community.elphel.com/files/php_scripts/split_mov_2.php.txtcan
split it.
If not - the solution might be replacing the headers with the ones from the
correct footage.

Could you also upload an mkv sample?

Regards,
Oleg
