vdatanet 1549 Posted July 31, 2019 Share Posted July 31, 2019 What is the audio bitrate? Stream #0:1: Audio: ac3, 48000 Hz, 5.1(side), fltp, 384 kb/s (default) Link to comment Share on other sites More sharing options...
Guest asrequested Posted July 31, 2019 Share Posted July 31, 2019 (edited) Reading this again, it appears as though downmixing is isn't being done correctly. What audio options does your TV have? Does it have an option to process the sound to a pseudo surround sound? What is your TV doing with your audio?

mad_cow 2 Posted August 1, 2019 Author Share Posted August 1, 2019 Um, actually I have no idea what audio options my TV has.

Guest asrequested Posted August 1, 2019 Share Posted August 1, 2019 Well, if other similar audio plays correctly, I'm wondering if the channel arrangement it wrong. I have an anime like that. The voice is on the front right channel etc. I keep meaning to fix it, but I forget about it. Can you share the file? Link to comment Share on other sites More sharing options...
vdatanet 1549 Posted August 1, 2019 Share Posted August 1, 2019 The strange thing is when transcoding is downmixed fine, so channel arrangement should be ok. We definitely need a sample to take a look. Link to comment Share on other sites More sharing options...

We definitely need a sample to take a look. Yeah, it's a weird one. But if the channels are wrong, depending on how it's downmixed, it could omit some channels and give the output he's describing. He has sound, but it's the wrong sound. Link to comment Share on other sites More sharing options...

mad_cow 2 Posted August 17, 2019 Author Share Posted August 17, 2019 Here's a link to the media files and the subtitle files that accompany it. https://www.dropbox.com/sh/x4hm72rbpqpyp2d/AAC8rP4ifvDt2xiX8aP01XZfa?dl=0 Link to comment Share on other sites More sharing options...
Guest asrequested Posted August 17, 2019 Share Posted August 17, 2019 I think I see the problem. The file header is saying that the audio is only 2 channel AC3, but ffprobe is reading the actual media correctly as 6 channels. There might be a simple fix.....

Guest asrequested Posted August 17, 2019 Share Posted August 17, 2019 (edited) Yeah, that's the problem. If I leave the audio set to auto, it plays correctly. But If i set it downmix to stereo, you only get the extraneous audio. Edited August 17, 2019 by Doofus Link to comment Share on other sites More sharing options...

Guest asrequested Posted August 17, 2019 Share Posted August 17, 2019 Someone with good knowledge of ffmpeg could probably give you a command line that would decode and re-encode it. I can do that in mpv, on playback. Link to comment Share on other sites More sharing options...
mad_cow 2 Posted August 19, 2019 Author Share Posted August 19, 2019 Thanks for looking into this. Good to see that it is a media issue and not a bug. Link to comment Share on other sites More sharing options...
