Cannot encode any video with sound other than stereo

Post by meddyaas » Sat Sep 09, 2017 12:16 am

Hi all,

Video >
bitrate = 2000
Rate mode = average
Format = H.265
Encoder = NVENC
Source = Auto (FFMEG)

Audio >

Format = AC-3
Encoder = Auto (FFMEG)

Sound >

Anything other than "stereo" and the encode gets stuck on preprocessing and I have to kill the application.

Source is AVC, AC-3 (5.1 channels)

have tried for several days to try and get it to work but nothing works. I would prefer to keep the audio as 5.1

the settings do not matter one bit, even after a full revert, just changing the Default 'Stereo' to 'Original' will prevent mediacoder from getting past the 'preprocessing' part.

Have you tried updating to latest version. Just tested encoding with 5.1 channel and there is no problem.
If it is stuck at analyzing, it's not the problem of encoding but the original file can't be parsed.

the exact same original files, using the exact same settings in MC, get recoded by earlier versions of MC.
this bug was introduced last year, i would guess second half. 0.8.50 had the bug for sure.

note: i have to use 0.8.34.5716 for daily recoding purposes, no version since has chosen to run at full speed on my main computer. 0.8.50 DID run at full speed, but was unusable due to this.

i just did some tests.
mediacoder with sound set to original gets stuck on preprocessing with any scene release i can find.
it works with .ts files i recorded myself from TV.
it gets stuck with a file i recoded (with mediacoder) FROM one of these .ts files.
