failing to install webcam server

[josephouverney]

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

[Jocko]

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

[Jocko]

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

[josephouverney]

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

[Jocko]

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

[Jocko]

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

Any new about your issue ?
