undefined symbol in ssc-ffmpeg.so: avcodec_register_all

[thorstenhirsch]

Hi,

it has already been some weeks (before the firmware update of my SB from 2.5.x to 2.7.x) since I played my last ogg file, but when I tried it today, the SB told me “unable to play that format” and the filename was marked with an ‘x’. I couldn’t even find it by its tags (i searched for the artist). I could only see the filename when browsing all songs by title. Anyway, I thought upgrading firefly to the latest version (1586) might solve the problem. But it didn’t. First I compiled it with the same configuration as I had before, so I enabled sqlite3, upnp, flac and ogg. There were no startup errors in the logfile, but something must went wrong, because mt-daapd was not linked to the shared libraries of flac or ogg. Anyway, I decided to give ffmpeg a try and that’s where I’m stuck now:

I already added /usr/local/lib to /etc/ld.so.conf long time ago. Here’s my output of ldd /usr/local/share/mt-daapd/plugins/ssc-ffmpeg.so:

By the way, firefly is running on a linkstation/mipsel.

Shouldn’t mt-daapd-ssc.sh find these commands?

# /usr/local/bin/mt-daapd-ssc.sh /mnt/hda/share/musik/niagara/la_verite/ultravision.ogg 0 0

/usr/local/bin/mt-daapd-ssc.sh: oggdec: command not found

/usr/local/bin/mt-daapd-ssc.sh: wavstreamer: command not found

Yeah, maybe not. Your environment for daemons might be pretty sparse. You can edit the mt-daapd-ssc.sh and add the full path to the files in the script.

And that’s probably your best best for transcoding — using ssc-script rather than ffmpeg. ffmpeg (like other open source projects I know. *cough*) doesn’t seem to ever release stable versions, which means its impossible to code for it, as the api is constantly changing. If you have a snap from another time period than I do, then our APIs are difference, and no work.

For the most part, I only added it for windows machines as they don’t have an easy way to fork+exec or popen a console program.
