Windows XP compatible non-SSE2 FFmpeg binaries

Meh, it's just that the MSFN guys are just overly concerned with not redistributing any Windows dll at all ever, so they didn't want that. Not that there's anything wrong with it, in fact the RyanVM guys were more than willing to link those things. Besides, the backported APIs are open source and publicly available on GitHub (which is owned by Microsoft by the way), while the redistributed dll are just Microsoft dll that one can find in any version of Windows, so it's not like we're doing something bad.

To circumvent the Python 3 issue (for now) I've switched to the Mbed TLS 2.28.2 branch, as mentioned earlier.
And I've re-added the time-stretching and pitch-shifting rubberband audio-filter, as per special request.

Outstanding news, Reino, thanks!
Speaking of which, are we gonna get a new build of ffms2 as well?
The last one was based on ffmpeg 4.5 while we're at 5.2

[Reino]

But latest commit is from 20-05-2021. Or would a release based on a newer FFmpeg make a difference?

Same ffms2, just based on a newer FFMpeg version so that decoders are new.
It would make a difference, namely it would:

1) Be able to decode Sony's IPCM
2) Be able to properly decode DNX120 interlaced

See https://rwijnsma.home.xs4all.nl/files/ffms2. Untested.

Doesn't work...



It's missing the Bcrypt stuff

BCryptCloseAlgorithmProvider
BCryptGenRandom
BCryptOpenAlgorithmProvider

[Reino]

Sorry, my mistake. Please re-download.

[FranceBB]

Works like a charm.

Four months have gone by, so it's time for another round of binaries. As usual, see post #1 for details.

This time there's one little difference though. I had to compile FFmpeg without libfdk-aac this time. It appears the FFmpeg developers have pushed quite some libfdk-aac related code the last couple of months, but Gianluigi hasn't updated his code yet (on which I depend). And I'm getting "undefined reference to"-errors with the patch in its current state. I wish I could code in C/C++, but alas.
This actually makes me wonder; do we really still need libfdk-aac? I haven't really been keeping up with FFmpeg's development progress lately, and its internal AAC encoder in particular, so does anyone know how this encoder performs quality-wise compared to libfdk-aac at the moment? I know at least that a couple of years ago it did pretty good already, though not yet as good as libfdk-aac.

Besides FFmpeg, one can also find new binaries/libraries of frei0r, openssl, curl and xidel on my host. And especially for FranceBB , I've compiled ffms2 (again, no new updates) against my latest shared FFmpeg release. This means that 'ffms2.dll' is really small now, but relies on 'avformat-60.dll', 'avcodec-60.dll', etc. somewhere in %PATH%.

Thanks for the new version, but this effectively makes this new build unusable for me. My Xtreamer external player does not get along with FFmpeg´s internal aac encoder, most audio which was encoded with the native FFmpeg encoder comes out totally distorted. There have not been software updates for my Xtreamer for many years now, and I will not discard it just for this reason.

Which means that I need to downgrade FFmpeg to the previous version again, I think that I will not be missing too many things.

You won't be missing anything at all, because libfdk-aac hasn't seen any updates since 31-05-2022.
For the next release I assume Gianluigi has updated his code.

Or maybe it's because fdk-aac is added for other systems like GCC that don't work with aac float ffmpeg.

Maybe use this

No problem, I've put avcodec-60.dll and avformat-60.dll in C:\Program Files\Avisynth\Plugins along ffms2.dll, ffindex.exe and ffms2.avsi and it worked like a charm.

@Reino
I've tried Your latest Build for FFmpeg v6.1:
Works perfectly for me on WinXP-Win10 + Linux with Wine (Win11 and macOS not tested yet).
Tnx, again for Your Work.

@manolito
This Player works with Reino's latest Build and AAC.
