PW4 Sox Media Player v2 KUAL extension

[dhdurgee]

Thank you for the testing. I guess I will need to check the version levels of the provided libraries in the original sox package and replace those two with the same version level to avoid this problem.

This suggests I need to do the same for the other support libraries to be sure I include working versions.

Regarding the UI, that is a limitation of KUAL. The best that can be done is what the author of the V2 did using Python to dynamically recreate the menus.

If you have a chance it would be helpful to know if there are any other missing dependencies among the library files and what levels of those dependencies need to be. At this point it appears that I either need to provide an appropriate libc6 of 2.28 or find versions of the library files that will work with the level present in the Kindle firmware.

I'm not sure if this will do it, but try unzipping the attached into your library directory and try the ldd again on the mad and mp3 library files.

It looks like that is not compatible.

Here’s a quick update on my testing with the new HF Sox package and libraries:

I confirmed my Kindle PW4 is running glibc 2.20 (checked via /lib/libc.so.6).

I tried playing an MP3 using the updated Sox, but got this error:

relocation error: /lib/libpthread.so.0: symbol h_errno, version GLIBC_PRIVATE not defined in file libc.so.6 with link time reference

I also checked the system’s environment and confirmed my current libraries (and that glibc is 2.20, not 2.27 or 2.28).

It seems the included libmad and libmp3lame libraries were built against a newer glibc than what’s on my Kindle, causing this error.

Thanks again for your help—happy to test more builds.

Also, here's a ton of info on my device if you have any more questions about compatibility.

BusyBox is a multi-call binary that combines many common Unix
utilities into a single executable. The shell in this build
is configured to run built-in utilities without $PATH search.
You don't need to install a link to busybox for each utility.
To run external program, use full path (/sbin/ip instead of ip).

Will look for versions built against glibc 2.20 and get back to you.

Dave

[dhdurgee]

I went back to the archives looking for earlier releases and have attached what I hope will be working replacements for libmad and libmp3. Please try these replacements and remove that libc from your library.

Let me know how it goes.

Surprised to see it's still going.

It actually could be done, when the solution is found for older fw versions I'll try to remember to make an update that will make working with individual files easier. I can't remember why exactly didn't I do this in the first place, but it could be just too much for KUAL and was dropped during testing.

Anyway, I've been thinking about adding an interface into overlay somehow, my best idea is to make it either a plugin for KOReader (if it's even possible, never used it), or to use LIPC and show the interface on an event. Or even make a separate app for audiobook listeners.

I've managed to track down useful events for those who might wish to try it before I have a chance. I've not been able to find an event that is triggered for the main menu, but the book overlay and the "crown" (which is status bar probably) is these two in com.lab126.winmgr:

titleBarVisiblityChange "invisible"
chromeVisiblityChange "chromeDown"

So one can subscribe to them like this:

lipc-wait-event -m com.lab126.winmgr titleBarVisiblityChange,chromeVisiblityChange

and track whether the overlay is open or not.

To find the actual menu event it would help to do:

lipc-probe -a
# get a lot of possible interfaces
# for each of them do
lipc-wait-event -m {interface} "*"
# lipc-wait-event -m com.lab126.winmgr "*"
# and try to open the menu

but it's a lot and obvious places didn't give me much.

It works. However, Is it possible to add options to play the next or previous tracks, or to manually select a specific song to play?

You say that it works, which particular audio formats are you able to play?

The v2 version uses Python to enable additional features, but that is not my code and I understand there are still problems getting Python running on the HF firmware.

I would suggest you get in touch with the author of the v2 code to see if he can get things sorted out for his code and Python in the HF firmware.

I'm sure there are any number of people who would be interested in you enhancing your version further, but first the issue of getting Python working reliably on the HF firmware needs to be resolved. Once your current version will run on HF firmware then work on further improvements.

As you can see here I have been working to put a working HF version together of the original version, but I am hampered by the lack of a Kindle with HF firmware to test on. If you have one I would appreciate someone checking which of the audio support libraries I cribbed from Debian Jessie are working and which are not. The sox binaries and libraries appear fine, it is the audio support libraries that are in some cases problematic.

This appears to mostly be related to the fact that the HF firmware uses GLIBC 2.20 and thus the binaries and libraries cannot depend upon a later release.

Thanks for your work on version 2 and I look forward to seeing a newer release.

Well, at the moment I have two PW4 Kindles, one with 5.10.1.3 (pre-HF, I guess) and one with 5.16.2.1.1 (HF, it seems). To the 5.16 one I've installed kterm -armhf from here, python3.9 with Update_python3_0.15.N_install_pw2_and_up.bin from here, set up v2 of the extension (figured out there's no individual track selection after opening the sources though, that's a bummer), connected the headphones and it just worked. Python opens from kterm, the player works but requires some patience since the menu update is not instant, maybe I'll need to add GNU Awk in the mix.

Let me know how can I help, pointers to the previous messages containing important information will be helpful since you had some progress already.

Interesting, I had thought that 5.16.3 was the first HF firmware.

At this point the best way you could help me would be to download the soxhf.zip from a few posts earlier and install it. Then download the libm.so.zip from a more recent post and overwrite those two libraries with them. At that point you should be able to test from KUAL and see what formats work.

You could also via kterm do the ldd on all of the audio format support libraries and see which ones are missing what dependencies. You don't have to check the libsox libraries as they are fine.

Once we get my version up and running you can update your version to incorporate the proper HF versions for that release. I assume there is no way to issue a single release for both.

Thanks again for any help you can give me.

Yep, went to check and it turned out that 5.16.2.1.1 is indeed not yet a HF version, I've only attempted to install kterm-armhf, but it failed to launch. At least that explains why does the player work.

As for testing, I don't see any benefit in updating (yet, gotta buy one more Kindle first) and to speed things up I'd suggest using Tailscale together with @Hubris, it has a feature called "subnet routers" that will help you get direct access to the Kindle with HF firmware. @Hubris will have to configure Tailscale on their PC to route their local subnet to Tailscale, enable SSH over Wi-Fi and add your PC as a second team member. Once done, you'll be able to just ssh root@192.168.1.123 to their Kindle from your device and do the testing.
