Script d’installation automatique de MediaSPIP

Progressive or Interlaced misinterpreted when transcoding to DNxHD mxf with ffmpeg
19 avril 2015, par OlleHi, don’t know if i am doing it wrong or is there a bug.
Trying to transcode 1080i Video from Quicktime Animation interlaced upper field with a stereo audio to MXF, DNxHD with discreet mono audio channels and video interlaced.
DNxHD = VC-3 op1a 120M.Everything works as a charm except for the end result is being tagged as Progressive ! I can see, when i look at the video, that it is interlaced and good looking, so everything is in order.
But the MXF file is identifying it self as a Progressive video, so our asset management system treat it as a progressive file 1080p and so does the Avid Mediacomposers.
I can’t se the problem with ffprobe but i can in MediaInfo v0.7.69
Se below.Command that i run :
./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 10:00:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000 -flags +ildct -y test.mxf
The transcoded file run with media info reports this strange result.
Scan type : Progressive
Original scan type : Interlaced
Original scan order : Top Field Firstseems as
-flags +ildct
don’t affect Scan type :The output from ffmpeg :
Olles-MacBook-Pro-2:NoBackUp olso$ ./ffmpeg -i OLLETEST_MANSZELM_ANIMATION.mov -timecode 00:10:00:00 -threads 16 -map 0:0 -map 0:1 -map 0:1 -map_channel 0.1.0:0.1 -map_channel 0.1.1:0.2 -vcodec dnxhd -b:v 120M -acodec pcm_s24le -ar 48000 -flags +ildct -y test.mxf
