PM won't play/stream media Topic is solved

[andyprough]

Hey @andyprough thanks for your help and patience, unfortunately the package built with explicit alsa support didn't fix the problem (btw the flag to disable dbus was rejected and I had to remove it). I wonder if there's a rather easy way to inspect the path that PM is searching for libavcodec and the like, maybe I could have misconfigured env variables or something?

Just out of curiosity I downloaded a live ISO of Endeavor and ran it in a vm. Here's the output of 'fd -H libavcodec /' -

Code: Select all

[liveuser@eos-2024.01.25 ~]$ fd -H libavcodec /
/usr/share/man/man3/libavcodec.3.gz

/usr/lib/libavcodec.so.60.31.102

/usr/include/libavcodec/

Just in case it's of any use.

Your media file from wikipedia and videos from yewtu.be are playing with audio on Pale Moon for me on this Endeavor live ISO when I download the tarball from palemoon.org and run the Pale Moon binary. I had to install dbus-glib and xcb-util in order to get Pale Moon to start.

Let me know if there's anything else you want me to explore on this Endeavor live ISO. Here's some gstreamer output that is supposed to give a list of all the codecs on the system. I don't know if this is the best way to list them or not, just a random command I found online:

@andyprough unfortunately I already had all those codecs installed, however I fixed one of the two problems and maybe this could help narrowing down the issue.
I looked at the terminal while launching mpv and I noticed that it complained about the numactl package missing (that means that I probably needed something to optimize CPU/memory management, quite odd): as soon as I installed the package, Invidious magically worked, even after uninstalling mpv. Also, the MP3 entry showed up in the Preferences->Applications list. But, when it comes to wikipedia audio files, the behavior becomes erratic: in the beginning, when clicking the playback/speaker icon, the browser did play the file but opening it in a separate tab. Then, after a few hours, this stopped happening and I couldn't play the files anymore, exactly as before...And, another time, it worked normally! However, when I visit https://www.merriam-webster.com/dictionary/ciao the audio files plays correctly (but I couldn't figure out whether it was a mp3 file or not).

You may have fixed it. I think if I recall correctly that the server that serves up wikipedia media files is kind of erratic.

If you want a lot of mp3 files to try, one of my favorite Bible radio sites has thousands of daily radio shows in mp3 format: https://thenarrowpath.com/radio_archive.php
They all play for me in a player in Pale Moon.

thanks for all your help andy, I have also tried some mp3s on the website that you suggested me. It keeps on playing the file in a separate window, opening the PM built-in player, is it the same on your side? Because I don't remember if it's the default behavior, FF simply plays the audio in the background.

Yes, it opens a separate window for me on Pale Moon and I get the media player, same like you I suspect.

I have just turned on the PC and tried again, guess what, this time the file is played in the background without opening any window, that's crazy I think it's a matter of some kind of intrinsec instability of my system, but it would be hard to guess what, I should ask some Arch dev in their forum (maybe I need to install yet another package?). However it's not a big deal, the most important thing is that the playback is working now.

Regrettably, I've already attempted this approach, assuming that the browser might perform better with PulseAudio and Apulse, but it proved unsuccessful. I also experimented with another Arch Linux-based distribution (Obarun Linux), only to encounter the same outcome, whereas the default browser, Midori, functioned properly.

If you already have PulseAudio then there wouldn't be any use for apulse that I can think of. If Obarun is using Midori as their default browser then the Obarun devs are probably compiling Midori specifically for their system. I don't recall enough about the Obarun system other than its use of the s6 init manager to know what options Obarun's devs would be building Midori with.
