Alan,

I've downloaded and had your code working before, but I just redownloaded and built it, everything went smooth, but when I run it now based on the command given in the README, it seg faults when I select the bounding box. In fact, the very first time I ran it, it froze every time i moved the window or tried specifying the bounding box. Now it just seg faults everytime

Hi could you try debbuging so that I can see when the seg fault occur?

Thanks

Never mind, I used the gdb and was able to get some output, here it is:

Hi, I can see that the algorithm cant find any good or bad bounding boxes
(Found 0 good boxes, 0 bad boxes). What parameters are you passing to the
program, how are you running it?
I'v seen this error before when the video file is not read correctly.

I just run the first command given in the README to use my laptop webcam... I've had this working before. I thought the seg fault was my fault from playing around with the code a little bit, so i just downloaded a new copy today, but it is still seg faulting. the command i run is ./run_tld -p ../parameters.yml -tl

What happens when you run it using a video?
by doing..
./run_tld -p ../parameters.yml -s ../_input/motocross.mpg -tl

This is the output:

VIDIOC_QUERYMENU: Invalid argument
VIDIOC_QUERYMENU: Invalid argument
VIDIOC_QUERYMENU: Invalid argument
capture device failed to open!

I tried the command above, but when I looked in the _input directory I noticed there wasn't a file called motocross.mpg... but there was one call motorbike.mp4. Regardless I tried both command, and they resulted in the same error.

Hi I just re-downloaded and tried the code but it worked fine with both
camera and video inputs. Have you made any change to the parameters.yml
file? or the ffmpeg software?

What OS are you on?

Could you also try running valgrind on it?

valgrind ./run_tld -p ../parameters.yml -s ../_input/motorbike.mp4 -tl

I haven't changed the parameters.yml at all. When I was compiling the software, I get the printf errors, and add #include <stdio.h> in the necessary files. Does yours compile before fixing those? Also, here is the output from running valgrind on the .mp4 file.... I haven't gotten the seg fault there though, because the video never even opens. Here is the output from valgrind:

Well, I just deleted my copy again, redownloaded and built it. The tracking using my webcam works now, but the second command to use the input video still doesn't work. same error.

Great to know that its working with the camera. I included the missing
headers so everything should compile fine now. I don't know why it doesn't
open the input video though. Try moving the video to the same folder as the
executable and just run

./run_tld -p ../parameters.yml -s motorbike.mp4 -tl

Or try it with a different video, I don't have any issues running it with
the video.
