Avidemux

Here is a simple tinypy script that will load all files with a mp4 extension in a folder.

#
# Load all the files in c:\tmp with .mp4 extension.
# That's it.
#
ext="mp4"
inputFolder="c:\\tmp\\"
#
def convert(filein):   
    if(0 == adm.loadVideo(filein)):
        ui.displayError("oops","cannot load "+filein)
        raise
    print("Done")
    
#
# Main
#
ui=Gui()
adm=Avidemux()
#
list=get_folder_content(inputFolder,ext)
if(list is None):
    raise
for i in list:
        convert(i)
print("Done")

The first part is the initialization. We set the input folder (beware, on windows the \ must be put twice, so c:\tmp\ becomes c:\\tmp\\) and extension '.mp4' here. Ending the path with a '\\' is a good idea.

ext="mp4"
inputFolder="c:\\tmp\\"

The we create the object that enables tinypy to interact with avidemux

ui=Gui()
adm=Avidemux()

All avidemux commands will be performed on the 'adm' object. Next, get the list of files with the given extension and call the 'convert' function for all of them

list=get_folder_content(inputFolder,ext)
if(list is None):
    raise
for i in list:
        convert(i)
print("Done")

You'll note that “list” is the list of files with full path to them, i.e. c:\\tmp\\foobar.mp4

def convert(filein):   
  if(0 == adm.loadVideo(filein)):
      ui.displayError("oops","cannot load "+filein)
      raise
  print("Done")

That's where everything happens. For this simple example, we just load the file, and raise an error if we cannot
