Audio desync with PCM source

Post by Deleted User 13735 »

Description of problem or question:

A recent round of tests indicates that audio from PCM sources may lead the video stream by >=42 to <=47 milliseconds in the encode. This desync is not apparent with compressed audio sources, including AAC and AC3.

Complete discussion at:
https://www.vegascreativesoftware.info/ ... s--111194/



Steps to reproduce the problem (If Applicable):

Encode a video stream with uncompressed audio to a complementary format in Handbrake.


HandBrake version (e.g., 1.0.0):

HandBrake 1.0.3 (2017022500) - 64bit
OS: Microsoft Windows NT 6.1.7601 Service Pack 1 - 64bit
CPU: Intel(R) Core(TM) i7-6850K CPU @ 3.60GHz
Ram: 16294 MB,
GPU Information:
Radeon (TM) RX 480 Graphics - 21.19.407.0
Screen: 1920x1080
Temp Dir: C:\Users\John\AppData\Local\Temp\
Install Dir: C:\Program Files\HandBrake


Operating system and version (e.g., Ubuntu 16.04 LTS, macOS 10.13 High Sierra, Windows 10 Creators Update):

Hopefully John will have some time to look at this one. Will be easier to track if you will create an issue on GitHub.

Desync aside, the log indicates level 4.1 isn’t valid for the frame size.

@BradleyS
Sorry for the confusion and distraction with levels. When Musicvid asked for my logs, I just zipped the whole folder. That UHD file was not part of the original test cases.

Here is the Mediainfo report for the source video for a 35 second project that I did last night:

Thanks for the logs. I've asked another developer who works on our sync code to take a look.

Although Youtube does its own processing, this test offers a fair approximation of what is going on. I treat it as more of an annoyance than a bug. I will elevate it to Github, however.

"I treat it as more of an annoyance than a bug."

My interpretation of this behavior is slightly different.

If the audio lags the video by a frame or two, it's an annoyance.

If the audio leads the video by a frame or two, it's a bug.

Can't escape that logic.
