ffmpeg 7.0.1 and Windows 7

[oniiz86]

I haven't changed ffmpeg defaults but if that is a desired change and simple to implement I would consider it.

@autodidact Thanks for the consideration, it would be greatly appreciated if you could implement this easily in the Windows 7 builds, the original eac3to developer madshi had disabled DRC in his custom FFmpeg build, the concern is about preserving the original dynamic range there is some old discussion about it here https://ffmpeg.org/pipermail/ffmpeg-devel/2015-March/170771.html

Does someone know how to use the apple aac_at in high efficiency 2 (aac_he_v2)

here it sais https://trac.ffmpeg.org/wiki/Encode/AAC#aac_at
Note: -profile option only accepts numeric values for aac_at encoder, e.g. 4 works as aac_he and 28 as aac_he_v2. (​https://trac.ffmpeg.org/ticket/9574).

so "-profile:a 4" (aac_he) is working but "-profile:a 28" (aac_he_v2) just crashes

I just tested with the version of ffmpeg I have
The -profile:a 28 fails with a bunch of errors.
I'm using the last 32-bit versions autodidact posted.

It is possible that a later version of audiotoolbox Encoder might be able to do this.
It probably would tale a later version of Windows than my Windows 7 32-bit.
Probably a 64-bit version of ffmpeg,audiotoolbox Encoder,& Windows could .

This is crashing on latest ffmpeg 8.1.1 from this post https://forum.videohelp.com/threads/414767-ffmpeg-7-0-1-and-Windows-7/page3#post2781425
Im on Win 10 64bit, and also the latest audiotoolbox files from https://github.com/AnimMouse/QTFiles

[autodidact]

I think with aac_at the aac_he_v2 profile may only work directly on MacOS. On Windows we use the
audiotoolboxwrapper which is based on qaac and that only supports aac_he.

QAAC only does LC and HEv1. It can use some of the audiotoolkit filters while it works.
