[FFmpeg-user] Converting from Avid DNxHD files results in black or white pictures only

Tue Feb 7 11:28:33 CET 2012


I have DNxHD encoded source files, from two different creators. I'm
unable to decode either of them, regardless of the output codec I use
in FFmpeg. Transcoding them with other applications such as Adobe
Media Encoder or QuickTime itself is not a problem though.

For example, just trying with a very simple command line.

The output file is available here:
http://dl.dropbox.com/u/24074822/dnxhd/out.mp4
It just shows a black picture in every player I've tried, from VLC to QuickTime.

The same happens with another DNxHD file as source.
Note that I have omitted all "Multiple ff_thread_finish_setup() calls"
messages in the following output.

What could be wrong here? I've never been able to properly decode
these source files, although all players show them without problems
(e.g. QuickTime, VLC, Premiere Pro).
I might be able to supply the source files, but they're rather big (~25GB).

Best regards
Werner Robitza
