problem compiling, ffmpeg related?

[multiplex]

hello everyone.. what i expected to be a simple upgrade as turned to

i recently upgraded to 12.04 Ubuntu (prior to upgrade)

i'm upgrading 1.25 to 1.26.3 from source

i get this during make



zm_ffmpeg_camera.cpp:85: undefined reference to `avformat_close_input'
zm_ffmpeg_camera.o: In function `FfmpegCamera::PrimeCapture()':
zm_ffmpeg_camera.cpp:118: undefined reference to `avformat_open_input'

This appears to be ffmpeg related, and i've tried a number of different versions as I read older versions work better on ZM? I tried current release and .10 along with the version provided by apt-get

any pointers?

Thanks!

What does your configure command look like?

[multiplex]

./configure --with-webdir=/usr/share/zoneminder --with-cgidir=/usr/lib/cgi-bin --with-webuser=www-data --with-webgroup=www-data --with-ffmpeg=/usr/local/lib CPPFLAGS=-D__STDC_CONSTANT_MACROS

I did manage to get a little further. Looks like i needed the dev packages of a few 'libav' components. libavutil-dev, libavdevice-dev, libavcodev-dev, libavformat-dev, libswscale-dev

now im only left with

zm_mpeg.o: In function `encode_frame':
/home/ppp-admin/ZoneMinder-1.26.3/src/zm_mpeg.cpp:40: undefined reference to `avcodec_encode_video2'

figuring it might be another library needed.

seems as though the compiled version of ffmpeg i had installed was fighting with the packaged version. I uninstalled ffmpeg from source and things cleared up

now i'm fighting a memory map error with zmwatch.pl - can't write to the given location

usually things go smoother for me

seems as though an error occured while migrating my DB from 1.25.0 to 1.26.3.

I ended up creating a new DB from scratch and everything seems to work now. Now i'll just move over my 20 monitors by hand

sorry to clog up the forums
