Do you have the example file somewhere? The link from the github issue was broken. And so is the gentoo handbrake ebuilds according to the handbrake forums. I'm using a custom ebuild, based on something I found in an overlay last year, would be interesting to try and transcode your file.

Thank you.
I have choosen a small file.
The files are from my camera. Well it was around 2008. So it has PCM audio.
coding log for that file. auto settings withotu doing anything, any changes on my side

Yes the content is a bit funny. It's just to remember something of the past.

Two flaws of handbrake.
PCM audio seems to be dropped from file when you just click convert.
Crop autosetting is bad, it halfs down the conversion rate.
The files are already at 640x480, so the middle section of the ratio screen gives double the conversion rate as the auto selected crop feature, which keeps the video also at 640x480.
I have not yet checked if there is a way to change those auto settings. I think crop is a bad feature! Not very smart to crop contents below some screen ratio. like 640x480, ... |

I tried running the file through the command line version, and the output apparently keeps the audio stream, and indeed muxes the encoded video and audio together at the end, but the resulting file is still silent, which is weird. | Code: | | HandBrakeCLI -i img_0010.avi -o TEST.mkv -e x264 --x264-preset slower -q 22 -E copy --audio-fallback flac24 |
The output indicates that the audio is fine.... | Code: | [16:28:02] scan: audio 0x1: adpcm_ms, rate=8000Hz, bitrate=32000 Unknown (adpcm_ms) (1.0 ch)

I'll try to take a closer look at the file when I get in front of the computer, did this remotely.

Scratch that, my video player at work was shitty, there's sound in my test encode, and I also get sound from the result of just opening your file in the GUI version and clicking encode. Here's a link to the ebuild I use, which you can put in your personal overlay.

Thank you.
May I ask how you read out the file properties ?
| Quote: | The output indicates that the audio is fine....

I just use the vlc hidden info dialog for the media.
I have to look later in the differences in these ebuilds. Or in the software components in question
It's good to know that it works on your side. |

All the output was from the HandBrakeCLI command. A good way to check out the details of a video is to use ffprobe, which is a part of media-video/ffmpeg.
