Hi Admin,

I'm trying to install the webcam server but I'm having this message "Fail: start command failed"

do you now the reason by the way im already a donor and i have enterd with my id on my server.

please Help

Hi

The issue is not related at all with your donator status but seems to be linked with the firmware or with motion settings. Please to note webcam server is not a "donator" feature.

First, do you have an usb webcam plugged?
So check if the firmware detects it => go to the usb-devices menu and post here the content

I could reproduce the issue on my 5big2 and it is a lib issue:

Code: Select all

root@Acrab:/ # /usr/bin/motion -c /share/1100/motion-webcam/motion.conf -p /var/run/motion.pid
/usr/bin/motion: error while loading shared libraries: libavformat.so.52: cannot open shared object file: No such file or directory


And indeed 3 lib are missing with the last firmware version

Code: Select all

root@Acrab:/ # ldd /usr/bin/motion
        libm.so.6 => /lib/libm.so.6 (0xb6ece000)
        libpthread.so.0 => /lib/libpthread.so.0 (0xb6eae000)
        libjpeg.so.62 => /usr/lib/libjpeg.so.62 (0xb6e88000)
        libavformat.so.52 => not found
        libavcodec.so.51 => not found
        libavutil.so.49 => not found
        libz.so.1 => /usr/lib/libz.so.1 (0xb6e68000)
        libsqlite3.so.0 => /usr/lib/libsqlite3.so.0 (0xb6dd6000)
        libc.so.6 => /lib/libc.so.6 (0xb6c9a000)
        /lib/ld-linux.so.3 (0xb6f7e000)
        libdl.so.2 => /lib/libdl.so.2 (0xb6c8f000)
        libgcc_s.so.1 => /usr/lib/libgcc_s.so.1 (0xb6c68000)


Now libav libraries are installed with some addons packages and we did not notice motion required some of them :pound
Currently you can fix the issue by installing minidlna and adding these symlinks (it seems there is no issue to use more recent lib versions with motion):

Code: Select all

Jocko: removed

With these symlink, motion starts without warning:

For a complete fix, we have to find the old libs from previous firmware image

So the missing lib are very old and compiled by fvdw in 2009!. We removed them wrongly on version 18.x

To restore them do

Code: Select all

plugout download 6498
tar -xf /tmp/fvdw-sl-18-x-libav-2009.tgz -C /

check if you find them

Code: Select all

ls -l /opt/lib/libav*

Then update the library cache

Code: Select all

ldconfig

Now motion should start without issue

Sorry how to i retore can you give some step by step. thansk

What is it that you do not understand with these commands ?

Code: Select all

plugout download 6498
tar -xf /tmp/fvdw-sl-18-x-libav-2009.tgz -C /

You just have to open a shell window to run them

Hi
It seems you managed to follow my instruction (at least download the package from your nas).

Any new about your issue ?
