Raspberry Pi B+ Streaming Video Error

[babadoctor]

I was following this tutorial on how to livestream video from pi and i got stuck at this part: http://gyazo.com/705640ee1a277e84b7a7d532e67adcbdthe tutorial is: http://blog.miguelgrinberg.com/post/stream-video-from-the-raspberry-pi-camera-to-web-browsers-even-on-ios-and-android and i was using the updated version of how to build and run mjpg streamer here: http://blog.miguelgrinberg.com/post/how-to-build-and-run-mjpg-streamer-on-the-raspberry-pi\\

 

it seems to have a problem with replacing the other file

Symbolic links aren't used to replace files, it's used to create a link, a sort of "shortcut". You're not able to create this shortcut because there is already a file with that name in the folder that you want to create the link. If you type cd /usr/inlcude/linux/ and then ls you'll most likely see that videodev.h already exists, I'm not sure how the thing you're trying to do works exactly but you could change the name of the file and then create the link.

nvm i just read that it overwrites the same file.

the ln -s command should have the source first and then the target but there was already a file with that name on the target path, that's why it failed. Maybe the software updated which made that step obsolete .

well i just ran into another problem... It wont stream onto my local network. it says that it cannot find the ./mjpg_streamer folder when i try to type LD_LIBRARY_PATH=./ ./mjpg_streamer -i "input_file.so -f /tmp/stream -n pic.jpg" -o "output_http.so -w ./www" after typing mkdir /tmp/stream

 

$ raspistill -w 640 -h 480 -q 5 -o /tmp/stream/pic.jpg -tl 100 -t 9999999 -th 0:0:0 &

 

any suggestions on what the problem might be?
