[supernath]

Hi i worked through you tutorial the first time round and it worked fine. Thankyou. However i want to use ffmpeg-php as well so i rebuilt ffmpeg but this time enabling the shared option (./config --enable-shared)
but i now recieve the error:
ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

Please can you help.

Many thanks

Hi

Whenever using the --enable-shared, you must make sure the appropiate libraries are available; while compiling as well as runtime.
Hence libavdevice.so, which in a regular build is compiled into libavdevice.a should turn into libavdevice.so.

So in which case, compile-time or run-time, do you experience this error?

I get stuck when i run make to install ffmpeg :

tea@Ceylon:~/Untarz&Zips/FFmpeg/ffmpeg$ make
/home/tea/Untarz&Zips/FFmpeg/ffmpeg/version.sh "/home/tea/Untarz&Zips/FFmpeg/ffmpeg" version.h 
/bin/sh: /home/tea/Untarz: not found
/bin/sh: Zips/FFmpeg/ffmpeg/version.sh: not found
make: *** [version.h] Error 127

I can't seem to find any useful information about make Error 127.

The ./configure step prior to this exits successfully...I don't really know what to do next.

Any similar experiences or ideas about what i could do?


cheers & thanks for a stellar tutorial.

That I would say depends on how often you use it. If you use ffmpeg once in a blue moon, I'd say probably whenever your workflow requires it - update before you start working on the stuff, and then leave it be unless there's some egregious problem. You could also follow the ffmpeg git changelog and see what fixes or new features matter enough to you to compile a new build.

If it's more regular, you could do anywhere from daily, weekly, monthly...whatever you prefer. There's the possibility of having an automated build system as well, where it'd just grab the source from SVN at a scheduled time (say every Friday at noon), compile, and install without any user interaction - I don't know how to do this, but I'm sure someone else on here could tell you.

Thanks, this worked great. I didn't need the x264 support, but it got ffmpeg turning flac files into mp3 quite well.

Hi, I installed latest version of Ffmpeg and x264 from http://ubuntuforums.org/showpost.php...&postcount=360
Now I have a new problem converting an .ogg to .avi that I didn't have before. The .ogg in question is actually the container- form output from recordmydesktop. Probably better explained from terminal output.....

:~$ ffmpeg -i out2.ogg -b 128 -ar 11025 -s 400x240 -pass 1 -passlogfile log-file outputx.avi

I don't know where I've gone wrong here, could somebody help me out please?
