which package(s) needed for Handbrake to render audio with AAC (FDK)?

English Multimedia
1

In Handbrake, when I transcode mp4 to mkv, the output file is missing audio if I set the audio codec to AAC (FDK) or to AC3. However, the output file has working audio if I set the audio codec to use *Vorbis *or AAC passthru. (passthru is, of course, expected to “just work”)

Does this mean that I’m missing package(s) that Handbrake needs for the transcoding? I *do *have the following packages installed, which I would have thought would be enough.

I have only libfdk-aac2. ghb readily transcodes mp4 to m4v. Never dared to tinker with settings.

What’s ghb?

I think I may have misunderstood my problem. What I thought was handbrake failing to produce audio may actually be VLC failing to play a video with audio of a certain format.

A new example:
handbrake transcodes an mp4 file into an mkv file with Vorbis audio: VLC can play it fine, including the audio.
handbrake transcodes an mp4 file into an mkv file with Opus audio: VLC can play the video but not the audio.

So would that mean that I’m simply missing a package required to play Opus audio? When I searched the repos for Opus, I had installed everything that seemed “obvious” for the purpose of playing Opus audio.

Thank you.

Show the stream information of the video generated by handbrake (aka ghb). Run the command in a konsole and post the output as follows:

I seems to me that the current Tumbleweed build of Handbrake is in fact defective in some way.

I have found that videos transcoded from .mp4 to .mkv with audio set to AAC(FDK) produces a mute audio track.

This is my ffplay output from one of these transcodes:

As you can see, the audio metadata is 0.

The same file transcoded with audio set to AC3(Pass through) shows the following output:

Now the audio metadata is non-zero.

I have a Leap 15.2 installation on another partition, and Handbrake functions normally there.

I would submit a bug report to Packman but I don’t see how.
