 Yes, but if I use the native decoder I get a different value:

 In short, of the various options I tried (libavcodec native decoder,
 display, okular, irfanview), only ffmpeg+libopenjpeg and okular were able
 to correctly decode the file generated by ffmpeg with libopenjpeg. It
 could also be a problem related to libopenjpeg.
