bug: unexpected audio behaviour and compilation

[spambroo]

I have cloned this repo and used 'make' cmd during that it shows,

but the compilation finally over... it starts to play well but after 20secs the audio starts to buffer.... (even after i have installed all the dependencies)

my system:
Ubuntu 22.04 LTS  WSL

[ravachol]

Thank you for this report, I will look into it.

[spambroo]

one thing i have to mention here,

when i installed kew through sudo bash -c "curl https://raw.githubusercontent.com/ravachol/kew/main/install.sh | bash"

it starts to play well but after 20secs the audio starts to buffer

but when i cloned the repo and installed through 'sudo make install'

it shows those my previously mentioned compilation warnings and when i starts to play it shows segmentation fault

[ravachol]

man that sucks. what version of ffmpeg do you have?

[ravachol]

If you run: ffmpeg -version dpkg -l | grep libavformat-dev

[ravachol]

The thing is that function signature should be only in version 4.4 of ffmpeg and earlier, so it's weird because you should be on a much later version.

[spambroo]

i have just used the cmd from your docs to install dependencies....

could you provide proper versions of those dependencies..... with cmd for that

[ravachol]

I think I fixed it.

Yeah, so ubuntu 24.04.4 LTS is running ffmpeg 4.4, but ffmpeg is at version 7.

However if you grab the latest kew from the main branch it should work on your version of ffmpeg.

[ravachol]

Please let me know if it doesn't.

when i compiled latest version of this repo again using 'make'

this warnings appears

when i tried to play a song segmentation fault appears as i previously mentioned with an image

[ravachol]

Those warnings shouldn't matter. The segfault does however.

[ravachol]

I see now that Ubuntu 24.04 has a kew version of 2.4.2. Maybe that is the latest version you can run. I don't know the details of why they didn't make a later version.

https://repology.org/project/kew/versions

[ravachol]

I tried installing kew 2.6 on Ubuntu 24.04 LTS and it worked, I couldn't reproduce the segfault. What kind of music file are you trying to play?

[spambroo]

its .mp3 file embedded with cover image..... and can we continue this conversation in discussions. ??

[ravachol]

sure. closing this.
