No audio with some videos

I get this error with some files, search a LOT, but can't find a resolution. I re-installed the audio codecs but didn't solve the problem.

With some videos the audio works very well

I'm sorry if the answer is somewhere, but I really couldn't find it.

This shouldn't happen. Can you post the output of mediainfo -f yourfile.mkv on a file that doesn't work, or post a sample file?

[vallx-ny]

Sure, here is:

Can you cut a sample and upload it somewhere? E.g. dd if=input.mkv.mkv of=output.mkv count=10000 creates a 10 MB file named output.mkv, that contains the first 10 MB of input.mkv.

[vallx-ny]

Sure, here it is: http://www.mediafire.com/download.php?zgqcl5hu7i750wx

[ghost]

Thanks, that's very helpful.

Somehow there's no audio at the start of the file, which breaks decoder initialization. I'll try to fix it.

[ghost]

Should be fixed now.

[vallx-ny]

I updated and tested, but still not working. I must say that this error only happens with 10bit encoded(the most recent ones, but doesn't work with any other player(besides vlc). There are files from the same source, that works.

Detected file format: Matroska [stream] Video (+) --vid=0 (h264) [stream] Audio (+) --aid=0 (*) (aac)

And the same error with another video

Maybe is the format of the encode(or like you said the splash image breaking everything), I don't know very well. I'll try with other file without that cover from another source.

Thanks for your attention and sorry for anything.

[ghost]

I updated and tested, but still not working.

The same file? The sample you posted works for me now. If there are any other files that are not working, can you cut a sample and upload it?

Thanks for your attention and sorry for anything.

You don't have to be sorry, reports about broken playback are very welcome.

[vallx-ny]

Thanks for all the support. Even the sample file that I posted for you doesn't works, I still get the error

Even after the update: http://i.imgur.com/Poufc8Q.png

Same error: http://i.imgur.com/vIZ1aJT.png

Maybe I did something wrong?

[ghost]

Since we're testing exactly the same file with (supposedly) using the same mpv version, I see two possibilities:

1. You're not using the mpv binary you freshly build or something similar. (Stuff like this happens often!)
2. Something is different about the default settings. Can you try with mpv -no-config -ao null output.mkv? Since this sets the null audio output, you won't hear anything, but it also includes a possible difference between our systems. You shouldn't see the decoder initialization errors.

[ghost]

Ping?

[vallx-ny]

Oh I'm sorry, I had some internet problems and couldn't respond.

So, for some reason it still does't work. So I tried mplayer2, and it works with leaves me conclusion that I did something wrong with the audio configuration. I tried the command that you asked me but I still get the same error.

I can't really see what I'm doing wrong.

[ghost]

Sorry for having you test so much, but you can post the full output of mpv -no-config -ao null -vo null -v output.mkv?

[vallx-ny]

No worries, you're already helping me so much.

mpv git-ba43d98

That's a git revision from before the fix.

ds_fill_buffer: EOF reached (stream: audio)

Yep, exactly the problem I fixed.

Your configuration is ok, but the mpv version doesn't include the fix.

[vallx-ny]

I was pretty sure that I had updated it... (new with git-hub and etc)

I'm so sorry for taking so much of your time with such a silly mistake by my part. I updated it and is working perfectly now. Thanks for all the help. and sorry for my innatention.

[ghost]

It's ok, I'm glad you reported a bug and you had the patience to provide enough information so that I could fix it.
