This is a library file provided by ffmpeg that it is not finding. Check and make sure you have installed ffmpeg and if you are building from source you will need the ffmpeg-devel as well.

I already successfully build ffmepg from source. what this message says it not that libavcode.so is not found, but that the symbol mm_flags is not found. any ideas?

There were no errors about undefined reference to `mm_flags' when you built ffmpeg?

can't be sure of that now. I just tried to recompile, but 'make' no longer does anything. is there a way to uninstal and start from scratch?

Thanks

ok. I did a make clean to start from scratch.

everything compiled and installed fine with only some warning. but this error message still come up when I ran the app.

I think from the build dir for ffmpeg you can run a
make uninstall
after that (only if the above comand worked) do a
make distclean
Then you can start over with ffmpeg. It has been a while since I've built and installed source so I could be wrong. I usualy now build the source into a packaged RPM and then install the RPM these days.

do you know if the ffmpeg used for zm needs the ffplay? I disabled that during configure. don't know if that's my problem.

I would say no, I don't think so, but I could not say for sure.

ok, found my problem!

there is a second copy of libavcodec.so hiding in another dir. all my new makes did not replace it. my folly.

now, I still don't know which of my fixes were necessary. but the app does run now.

Thanks so much!
