• avcodec/opustab : Avoid indirection to access ff_celt_window

  avcodec/opustab : Avoid indirection to access ff_celt_window
  Currently, it is accessed via a pointer (ff_celt_window)
  
  exported from opustab.h which points inside a static array
  
  (ff_celt_window_padded) in opustab.h. Instead export
  
  ff_celt_window_padded directly and make opustab.h
  
  a static const pointer pointing inside ff_celt_window_padded.
  
  Also mark all the declarations in opustab.h as hidden,
  
  so that the compiler knows that ff_celt_window has a fixed
  
  offset from the code even when compiling position-independent
  
  code.

• Iterate recursively in every subfolder and run a batch file

  6 août 2018, par Gokul Nair

  Please look at the following scenario wherein a folder A has many subfolders with different names. These subfolders have n number of .jpg files, which I am trying to scale and crop.

  Folder A\
  
    SubFolder 01\*.jpg
  
    SubFolder 02\*.jpg
  
    .
  
    .
  
    .
  
    SubFolder xx\*.jpg

  These sub-folders are with different names and do not have a trend when it comes to its names.

  I have created a batch file which would scale and crop images. This is working perfectly. I need to run the following command (name of file : ScaleCrop.bat) in each SubFolder xx :

  for %%I in (.) do set CurrDirName=%%~nxI
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=-1:260, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=260:-1, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  pause

  The command Scales and crops the image in the folder and saves these files in to a folder named SacledImages, which too has subfolders of the same name (SubFolder 01, SubFolder 02,…,SubFolderxx).

  I have created another .bat file which I used to copy ScaleCrop.bat to each subfolder.

  for /d %%a in ("C:\Users\Name\Desktop\Folder A\*") do copy " C:\Users\Name\Desktop\Folder A\ScaleCrop.bat" "%%a"

  How could I code a batch file run and execute ScaleCrop.bat from each of these subfolders ?

  I tried using the following code, but this just calls the .bat file inside each subfolder, however it is not executing :

  for /f %%f in ('dir /ad /b') do start %%f\ScaleCrop.bat

  I Tried the following as well, this does the trick, but all images are getting overwritten as the scaled-cropped images are saved on to /SacledImages Folder and not inside ScaledImages/SubFolderxx :

  for /r "C:\ Users\Name\Desktop\Folder A " %%a in (.) do (
  
    pushd %%a
  
  for %%I in (.) do set CurrDirName=%%~nxI
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=-1:260, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  for %%a in ("*.JPG") do ffmpeg -i "%%a" -vf ^"scale=260:-1, crop=250:250^" "..\ScaledImages\%CurrDirName%\%%a.JPG"
  
  pause
  
    popd

• Revision cd2cc27af1 : Removing redundant calls to clamp_mv2. We could avoid calling clamp_mv2 because

  24 août 2013, par Dmitry Kovalev

  Changed Paths :
   Modify /vp9/decoder/vp9_decodemv.c

  
  
  Removing redundant calls to clamp_mv2.

  We could avoid calling clamp_mv2 because it has been already called
  inside vp9_find_best_ref_mvs function.
