[FFmpeg-devel] FSB File Version 5 Support

[Michael Tonks]

Hello I am trying to convert some files that have the .fsb extension using
ffmpeg, and received an error:

version 5 is not implemented

along with the following message:

If you want to help, upload a sample of this file to
ftp://upload.ffmpeg.org/incoming/ and contact the ffmpeg-devel mailing
list. (ffmpeg-devel at ffmpeg.org)

The sampel file is available via github here:
https://gist.github.com/miketonks/b9fe5b647407a44c86c65a017927e7d9

The full command and out put is:

ffmpeg -i ambient/weather/rain1.fsb test.ogg

[fsb @ 0x555abcc746c0] version 5 is not implemented. Update your
FFmpeg version to the newest one from Git. If the problem still
occurs, it means that your file has a feature which has not been
implemented.

ambient/weather/rain1.fsb: Not yet implemented in FFmpeg, patches welcome


After a bit of digging I found that in libavformat/fsb.c#L48
<https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/fsb.c#L48> there
is support for version3 and 4 but not version 5.  Last updated 2015.

FYI The files I am using are from the Minecraft Vanilla Resource Packs
published at:

https://www.minecraft.net/en-us/addons

https://aka.ms/resourcepacktemplate

This is the file format used to make addons for minecraft - I'm just
playing around with the kids but it would be great to be able to build out
own sounds for the game on linux, any help much appreciated.

Many thanks,

Mike
