Audio conversion of a TrueHD video to TrueHD or E-ac3 (DD +) using ffmpeg to convert

[Gilson dos Santos tavares]

Dear, please, does anyone understand ffmpeg well?
I have a video in TrueHD that when I play it on my Blu-ray which is TrueHD it informs that the audio cannot be supported, I thought about converting and I have tried all, hanbrake, Davinci, Audacity and none can do this type of conversion, Handbrake it even has a TrueHD option but also my blu-ray doesn't recognize it and I have other videos in TrueHD 7.1 that I have no problems playing, just this one !!
I found this code in a publication and I thought it could be used for my case, I tried but it presented errors in the conversion, please someone who understands ffmpeg can help me? Can I adjust this code to what I need? Thanks!!
Look:
For example:
ffmpeg -i "input.thd" -c:a eac3 -b:a 1536k "output.eac3"
or within a container:
ffmpeg -i "input.mkv" -map 0 -c:v copy -c:a eac3 -b:a 1536k -c:s copy "output.mkv"

Is it a bluray disc or something else? ( ).

@lovinthehd Thanks for writing, no, I downloaded a trailer from a trailer-only website, it has 0:24 seconds

Yeah downloads can be sketchy....

@lovinthehd but it is in TrueHD but it is a format that my blu-ray does not recognize the audio but my blu-ray is TrueHD, I find it strange that it doesn’t work, that’s why I’m looking for someone who knows the ffmpeg codes because the best I could do was to transform this DD +/E-ac3 audio trailer!!

Why would your player recognize a pirated format?

@lovinthehd
Why pirated?
It's not a movie
It's a trailer
Sorry but I wanted to understand why you are writing do you understand ffmpeg or are you a tax inspector of people who pirate a disc?
Remembering, this video of mine is not a disc you understand?

@lovinthehd Dear, I'm sorry, I don't want to be rude but if you don't understand ffmpeg nor should you be writing, I'm just writing to talk about a subject I know!!

Don't call me dear Not sure what your particular application with source/gear is at issue....dear.

@lovinthehd
I don't know which translation you are using I would never call you hanny or Darling and the correct translation is darling no "Dear" and in fact Dear is Dear, Caros, Gentlemen....
If you don't know what I'm looking for and how I use it, I don't understand why you wrote it and even worse, you don't know anything about ffmpeg, when I see a publication I only write if I understand the subject being questioned !!!

So, lots of stuff said, but nothing to get to actually getting the disc to play.

Short story, it's not going to play like a standard disc would because the player expects a specific folder structure with supporting index files in it in order for it to know what to play and where.

HOWEVER, if your player supports different file types (many do) such as .mp4 or .mkv then you can simply put your trailer into a container and plug a USB drive into your player and go.

You are MASSIVELY overcomplicating this. It really just depends on what formats your player supports. You shouldn't have to re-encode anything, or change it to a different codec.

@panteragstk Thanks for the comment, in fact this video is not on a disc, I put it on a USB stick to play on my blu-ray, there is a website that I believe has a partnership with the film production companies where it makes it available for you to download some trailers Dolby Atmos, TrueHD 7.1 or Dolby or 5.1 dts. My blu-ray is native TrueHD, I have some trailers in Atmos and TrueHD that reproduces without any problem, only the one that doesn't work, as I said in the publication I already changed the audio to DD + / E-ac3 but the purpose of my publication was find someone you know from ffmpeg because maybe that person knows a code for TrueHD 7.1 audio!!

If the track doesn't come with TrueHD, then converting something else to TrueHD is a pointless exercise. It will cost you time and get you no increase in quality. FFmpeg doesn't encode into the lossless formats, but can encode into multichannel PCM.

@panteragstk
Now I understand what you mean
But what I had thought is that the ffmpeg would change the encoding when converting to TrueHD but not as a copy, but instead doing the conversion just so I would be able to reproduce it on my Blu-ray
And I just thought that because my Player on the Notebook had a ffmpeg code to do a specific encoding to reproduce this video perfectly, I imagined that by doing this conversion on ffmpeg I would be able to reproduce it on my device !!
This conversion that I did I can reproduce in Dolby Atmos too but is in a low quality 448k which was what I was able to do since I don’t have the code information to have a better quality
The funny thing is that of all that I have, this is the only Trailer that has no audio when playing on blu-ray

Yeah, those trailers you can download (although free, and not illegal) can still be pretty sketchy.
