Unable to Convert to MP3 on Raspberry Pi 5 / arm64 / aarch64

[jcarletto27]

Describe the bug I receive an error "Conversion failed" when I run LibationCli convert on my raspberry pi, I've tried this in docker, and a bare install to the host raspberry pi system with the same results. the logs claimed it could load the ffmpegacc.so or ffmpegacc.arm64.so so I compiled it myself and linked it but I still see the same issue.

thanks again for such great work!

To Reproduce Steps to reproduce the behavior:

1. install latest version of raspberry pi os debian bookworm
2. download libation 11.1 for linux arm64
3. sudo dpkg -i the deb file
4. download an audible book (successful)
5. libationcli convert

Expected behavior libationcli convert should create an mp3

I'm about to be nothing but bad news:

1) I'm beyond novice at all things Linux. Chardonnay uses tech which is out of the box supposed to work for mac and linux. Aside from what you see in my docs, this is more or less the extent to which I'm able to support linux 2) In the morning I fly out for quite a while so I wouldn't be able to address this even if I did know what I was doing 3) This error technically appears to be from a dependency of mine: AAXClean. I'm not sure if he still maintains it. I recommend opening a ticket on his page. Maybe also reply here with a link to your new ticket so they can be connected:

I feel bad about my lack of success here in general and for you specifically as a recent tipper. I'd do more if I could.

[jcarletto27]

No worries, I'm a software dev too, so I get it. I'll see what I can do, and maybe off a PR or a docker image if I get it working.

thanks again for such a great program! aside from the MP3 conversion it's been great!

[rmcrackan]

If you can fix this with a PR I'll for sure take a look when I get back in town. Best of luck

I have no idea if the 11.3 changes affect Linux builds or not, but perhaps something in there fixes the issues? I was just looking, and saw this: AAXClean upgrade to .net8.

[jcarletto27]

Thanks @CLHatch I did test that but to no avail. This seems to be an issue with missing and loading libraries on arm64/aarch64.

Thankfully I just had luck moments ago! I built the libraries from AAXCLEAN.Codecs inside the docker container (not sure if this is important), moving them to the core libation folder were LibationCli sits, and then added a config in /etc/ld.so.conf.d/ that points back to the libation executable folder. Then cleared the cache by echo "" > /etc/ld.so.cache then ran ldconfig to repopulate the cache.

I'm now successfully converting to mp3 on the RPI 5

moving those same .so files to another folder that already exists in the conf.d folder might have also worked but I didn't test it

[jcarletto27]

here's a copy of my built .so files and my conf in case this is helpful to anyone else having the same problem. I'll see about adding these steps to the Dockerfile somehow

I was able to push a docker image for use by others
