Replay gain settings issue

[Gracus36]

Hello.

Just saw this issue while trying to play with replay gain settings.

If you try to change replay preamp or default replay gain options, vlc will freeze.

Then it ask if you want to close the app and once restart, settings value are not changed.

Will probably not be able to provide a log due to vlc freeze and restart, but I can provide screen recording if needed.

I haven't seen that behavior. Do you have LogCat Reader? If you are comfortable using adb it's another good way to capture crash events.

https://play.google.com/store/apps/deta ... .logcatapp

Use ADB to grant android.permission.READ_LOGS to LogCatReader (you'll need a USB cable for this part):
adb shell "pm grant com.dp.logcatapp android.permission.READ_LOGS && am force-stop com.dp.logcatapp"

Once inside LogCat, you can add a filter (upper right corner) for ERROR level logs. It should quickly cut through the informational messages and reveal the issue. There is a share option in the menu which makes it easy to save the logs to Google Drive (or any other app installed on your device).

Will try to get a computer from a friend but not sure it will be possible...

Hope someone will have the same issue and will be able to provide a log...

Did you confirm the issue is not showing up inside VLC under More->Settings->Advanced->Debug Logs? See if you can start logging and trigger the crash.

[Gracus36]

Will try. But keeping in mind that vlc restart, I do not think it will be shown in vlc log...

[Gracus36]

As expected, nothing seems to be shown in vlc log....

All I see is this showing in loop in the log...

If it's a crash, VLC will save it on the disk. If you're using the beta version, you can send it by using the crash reporter. If it's an ANR, I'm afraid you'll need to provide logs with adb.

[Gracus36]

Vlc totaly freeze

Here is a screen recording:

Can you confirm it is a crash or an ANR?
If it's a crash, where the log should be saved?

[Gracus36]

So, I juste use the crash reporter.

It sends the db.zip and logcat.zip.

Hope it will help while I try to get a computer to try to get more information...

[Aza]

It's not a crash, it's an ANR (Application Not Responding). Unfortunately, the crash reporter is useless here. I saw you use a Samsung device with Android 12 si I tried to reproduce this on a similar devices but was not able to.
If you can use adb, a full logcat would be useful.

[Gracus36]

Thanks.

I will follow rstone advice and use logcat reader to find what happen

[Gracus36]

Just saw a weird thing...

Uninstall end reinstall vlc : a lot of setting have not been reset to default.

Start to think that the last samsung update went a little bit wrong.

Will reset my phone from scratch and come back to you with a log if issue is still there...

[Gracus36]

Hello.

Do not know what have been change in RC3 but the issue seems to be solved.

Thanks.

[Gracus36]

Hello.

Come back on this one.

Replay gain settings can now be change but it seems that replay gain is not applied even if audio file has replay gain info in tags...

[Aza]

Do you have a sample to share?

[Gracus36]

Here you go : https://bun.filedit.ch/MXImlZhooBWtUGNNaBJm.mp3

Replay gain info have been put in tags with foobar.
Media info show them.

If I play the file with foobar, replay gain is applied.
If I play it with vlc, volume is higher like if replay gain is not applied.
Same settings for the 2 software : track mode and gain only.

[Gracus36]

Any news on this issue?

[Gracus36]

Here is a log if it could help

Found some line about code not being supported anymore but found nothing about replay gain...

[rstone]

There seems to be an issue with the presence of the video stream for the cover art. If I reprocess your file and strip out the art it works correctly.

ffmpeg -i source.mp3 -map 0 -map -0:v -c copy destination.mp3

You can see the problem via VLC on the desktop, too. Load the media information and navigate to codec details. There should be two additional entries in the details: one for track replay gain and the other for album replay gain. If you do not see it on the desktop, it's not going to work under Android either.

[Gracus36]

I do not have computer. All is done on android.

Files are tagged with automatag app using id3 v2.4.
Replay gain values are added in tag with foobar replay gain scanner.

MediaInfo app see perfectly track replay gain AND album replay gain.

If I play an audio file with foobar, both can be applied if I use track mode or album mode.
With vlc, none of them can be applied no matter if I choose track mode or album mode.

If I understand, you say that vlc deal with the artwork like a video stream? What would be the purpose to use a video stream to display a static picture...

I can see the ReplayGain info in the desktop version of VLC, however it is ignored and has absolutely no effect at all on the desktop version either.
But ReplayGain of this file is working fine with AIMP and Foobar on both Windows and Android.


Side note: the Metadata tab of the desktop version of VLC has non resizable columns, so you can't see the full name of the tags whilst the value column is taking about 4/5 of the width.

[Gracus36]

At least I know I'm not the only one having issue...

[Aza]

I'll let the people in charge know about it.
