Samuel Mimram commented on LS-636:
----------------------------------
The problem seems to come from the feeding rates. The file is 48000 Hz / 24fps.
The generator is fed alternatively with
- 1 frame
- 1024 audio samples
Converted in tikz (with 48000 tikz per sec):
- 1 frame = 2000 tikz
- 1024 samples = 1024 tikz
so video feeding is at a higher rate than audio feeding, thus the leak!!!

> As reported on the ML (

> leak highly suspected...).
> set("frame.video.channels",2)
> set("frame.audio.samplerate",48000)
> set("frame.video.width",320)
> set("frame.video.height",240)
> set("frame.video.samplerate",25)
> s = single("big_buck_bunny_720p_stereo.ogg")
> s = mksafe(s)
