Hello,

Antispoofing.optflow was produced an error like this;

Traceback (most recent call last):

File "./bin/motion_framediff.py", line 24, in <module>

sys.exit(antispoofing.motion.script.framediff.main())

File "/home/ubuntu/work/antispoofing.optflow-1.0.5/eggs/antispoofing.motion-1.1.1-py2.7.egg/antispoofing/motion/script/framediff.py", line 76, in main

input = bob.io.VideoReader(filename)

RuntimeError: The detected decoder (`h264' = `H.264 / AVC / MPEG-4 AVC / MPEG-4 part 10') for the video stream on the input video file `database/train/real/client001_session01_webcam_authenticate_adverse_1.mov' is not currently supported by this version of Bob. Convert the video file to a supported codec or disable the `check' flag on the VideoReader object (if you are sure of what you are doing).

But i check the supported codec on bob site and set the file which is supported (ffmpeg).

Which format is supported by Bob 1.2.2?

Thanks.

Bob uses ffmpeg (or libav) to read the input file. So, the answer is "whatever your version of ffmpeg/libav supports".

To know exactly what decoders are supported by the ffmpeg/libav version you have installed, you can do like this:

$ python

...

>>> import bob

>>> import pprint

>>> pprint.pprint(bob.io.supported_videoreader_formats())

>>> pprint.pprint(bob.io.supported_video_codecs())

For example, in my present system, these commands show:

'long_name': 'AVI (Audio Video Interleaved)',

'mov': {'extensions': ('mov', 'mp4', 'm4a', '3gp', '3g2', 'mj2'),

Hello,

I found a sample video on idiap web site and those are working. it seems that my video was produced via mistake settings. i will fix it. Also the other problem is about face location files. How can i produce a face location files as ".face"? I searched it in the bob packages or antispoofing packages but i did not find.

Regards,

Devrim DONER

Hello,

These files are text files with 1 line for each frame in the matching video file.

Each line corresponds to:
