#4089 new defect

Audio delays in AV Foundation capture

Reported by: LordHDL Owned by:

Version: git-master Keywords: avfoundation

Blocking: Reproduced by developer: no
Analyzed by developer: no

Description

Summary of the bug: When screen capturing with audio on OS X, the audio will lag behind video. The actual amount of delay varies. It can sometimes be half a second or sometimes 2 full seconds.

How to reproduce: Record video and audio with AV Foundation. Since built-in output is not yet available as a device in ffmpeg, I used Soundflower (2ch) instead.

Please keep in mind that the following example video was actually the best output file I've gotten in all my tests. Most of my results have severe audio delays. https://www.dropbox.com/s/rmd2p9qi3sltvdi/audiotest.avi?dl=0

Update on this; I believe I know what causes the delay. It seems to happen when you attempt to record using a file name that exists and get the prompt to overwrite the previous file. It doesn't happen when using -y or when using a non-existing file name.

Here are examples and outputs: https://www.dropbox.com/s/bujc3oxaqtxxexi/overwrite.tar.xz?dl=0

I would like to see the samples of your tickets but I would have to register with dropbox which I will not do. Please attach samples to the tickets you've opened.

I have to let go the mouse?! Thanks! ;)

Registering with Dropbox is not necessary. They prompt you to register but you can just close the prompt and download as a guest anyway.

Note: See TracTickets for help on using tickets.
