Hi Cedric,
are you able to extract correctly 20m bands information using gdalinfo
(you need gdal >= 2.x)?
gdalinfo
SENTINEL2_L1C:S2A_OPER_MTD_SAFL1C_PDMC_20151206T152255_R093_V20151206T094609_20151206T094609.xml:20m:EPSG_XXXXX
Check examples on gdal s2 driver documentaton:

I answer to myself,
after compiling with gdal 2.1 it's the same: it works well but the
syntax that I use to extract only 20m bands give the same results as 10m.

Hi,
thanks for the tricks.
I have tried and it works well with 10m.
However, I tried to extract 20m bands and the results is the same as
10m.
otbcli_ExtractROI -in

-out /media/sf_clardeux/TMP/S2/roi_s2.tif uint16 -startx 10000
-starty 15000 -sizex 5000 -sizey 5000
What should be the good command line ?
For information, in windows (not ubuntu for otb), I tried with gdal
translate and it works very well.
I will try to compile again otb with superbuild but with gdal 2 and
not 1.11

I've downloaded a L1C product today and make a quick experiment
with OTB
(otb trunk compiled against gdal trunk with integrated s2
driver) and
monteverdi and it works well so far.
- ReadImageInfo is working without problem (on L1C product and
also on
subdatasets with each resolution)
I was able to access S2 10 meters bands using OTB extended
filenames ans
"sdataidx" keyword.
I've made an extract 10000*10000 using the ExtractRoi application:
./otbcli_ExtractROI -in
"/product_path/S2A_OPER_PRD_MSIL1C_PDMC_20151208T114907_R120_V20151208T070604_20151208T070604.SAFE/S2A_OPER_MTD_SAFL1C_PDMC_20151208T114907_R120_V20151208T070604_20151208T070604.xml?&sdataidx=SENTINEL2_L1C:S2A_OPER_MTD_SAFL1C_PDMC_20150818T101440_R022_V20150813T102406_20150813T102406.xml:10m:EPSG_32632"
-out ~/temp/roi_s2.tif uint16 -sizex 10000 -sizey 10000
What we should do now:
- Test the support with gdal 1.X (with the superbuild for instance)
- In Monteverdi we can't for now use extended filenames syntax
to open
directly subdatasets from a product (from the GUI or from the
command
line). We need most likely a dedicated interface to browse and
select
subdatasets wich corresponds to a set of bands in a specific UTM
zone.
All the info can be retrieved from gdal.
Note that there are some useful examples in the driver
documentation to
access subdatasets, create VRT, convert products tiled tif...
