list index out of range

[anotherancientalien]

Hi;
VideoFiled uploading video but after uploading I have this error:

Exception Value: list index out of range
Exception Location:/library/videothumbs.py in generate_thumb, line 51

line 51:
for c in range(len(histogram[0])):
ac = 0.0
for i in range(n):
ac = ac + (float(histogram[i][c])/n)
avg.append(ac)

How can I solve the problem?
Thanks in advance

Could you possibly toss a debug statement in so we can see what histogram contains? Is PIL, ffmpeg properly installed?

With print histogram:

try running ffmpeg from a terminal. If you receive this message 'sh: ffmpeg: command not found' or similar then you will need to create a symlink (or copy the binary) from the ffmpegx application folder. Since ffmpegx is a GUI, it does not install the ffmpeg commandline tool by default.

Try this:
sudo ln -s /Applications/ffmpegX.app/Contents/Resources/ffmpeg /usr/local/bin/
sudo chown root:wheel /usr/local/bin/ffmpeg
sudo chmod 755 /usr/local/bin/ffmpeg

FYI: videothumbs is now wrapped within a package installer and is available via Python's Package Index. Cheers!
