Great stuff Chandan, this fixes one of the main Freevo-1.7 bugs.
There is one new problem:
> + for (item, dir_str) in config.AUDIO_ITEMS:

causes a crash when the web radio has been activated, web radio is a
single fxd file and goes into AUDIO_ITEMS.
What is a bit of a problem is large image files, 7.2MegaPixel cameras
give an image typically 3072x2304 which is approximately 3MB, the
directory takes ages to display the images when there are more than a few.
What I have suggested to Wout is that we create a small image, and use
this as the img src.
The code to do this is (about line 510):
small_image_path = self.cache_dir + filepath.replace("/", "_")
if not os.path.exists(small_image_path):
size = (info['width'], info['height'])
new_size = self.resize_image(filepath, size)
image = imlib2.open(filepath)
new_image = image.scale(new_size)
new_image.save(small_image_path)
If you or Wout would like to do this it would be great.
I will need to do the same when "freevo cache" is run, but this needs to
be done first.

These didn't work in the original patch either.

The go into the overlay directory as raw files. From util/videothumb.py:
if image.mode == 'BGRA':
image.mode = 'RGBA'
if imagefile.endswith('.raw.tmp'):
f = vfs.open(imagefile[:-4], 'w')
data = (str(image.get_raw_data(format=image.mode)), \
image.size, image.mode)
f.write('FRI%s%s%5s' % (chr(image.width), \
chr(image.height), image.mode))
f.write(data[0])
f.close()
os.unlink(imagefile)
They get decode in util/fileops.py:
def read_thumbnail(filename):
"""
return image cached inside filename
"""
f = open(filename)
header = f.read(10)
if not header[:3] == 'FRI':
return read_pickle(filename)
data = f.read(), (ord(header[3]), ord(header[4])),\
header[5:].strip(' ')
f.close()
return data
image = pygame.image.fromstring(\
str(url.get_raw_data(format=url.mode)), url.size, url.mode)
Thanks again,
