Software News : FFmpeg 1.1.3 now available for OS4
Posted by MickJT on 2013/3/8 19:04:32 (1690 reads) News by the same author
Software News

FFmpeg 1.1.3 has been ported to AmigaOS4.

It includes thousands of improvements and support for a multitude of new decoders, encoders, muxers and filters.

Notable features are the ability to burn-in subtitles through the use of the new subtitles filter (via libass), and the support for converting and playing MOD/MED modules (via libmodplug).

The first time the subtitles filter is used, a cache will be built by scanning the contents of Fonts:_TrueType

Amongst the new filters are audio resampling from any format to any other, scene detection, volume detection, super2xsai scaling, logo removal, deshake, temporal deinterlacing, smart blur and many more.

You can download it now from OS4Depot.

 Re: FFmpeg 1.1.3 now available for OS4

I did notice one glitch decompressing the archive on my OS4 beta
system: there is a "Generic_PPC" directory while the Unpack script
is looking for "Generic PPC".

I renamed the directory (changing the "_" to a space) and then the
Unpack script worked just fine.

As commenters on OS4Depot mentioned, you have to protect the resulting
executables with "+e" to be executable and then everything works

Thanks again!

I'm not sure what you're using to extract. There's no underscore in the directory. You can see that when you click "Show Contents" on OS4Depot. UnArc, LHA and Dopus4 (XADmaster lib) fine here.

Should I re-upload it and add some lines in the script to add the executable flags, or is it not worth it for just that?

 Re: FFmpeg 1.1.3 now available for OS4

Actually you both are correct.

I os4depot there is not underscore (show content)

But when I unpack it with unarc in OS4, in result there is underscore.

As this xdelta3-decoder was another new thing for me in amigaland, I was totally without idea at start... :)

Thank you, great package!

@pjs / @Mlehto

You're using the broken internal LhA decoder. Try this one: http://www.unsatisfactorysoftware.co.uk/download.php?file=xad_lha

Indeed, updating XAD's LHA plug-in and rebooting
fixed decompressing and the space/underscore

I thought I'd already done that. hmm....
probably on another machine. ;)

I have re-uploaded this to OS4Depot to use a fixed libmodplug (works with .med), and updated the Unpack script to set the executable flags on the files.

Sorry my ignorance, but does this archive contains a libavcodec? Wich is used by several programs, like dvplayer?

Is this fast enough to be usefull with 800mhz Saam EP Flex

 Re: FFmpeg 1.1.3 now available for OS4
libavcodec is in the libffmpeg.lha package. avcodec.library is based on libavcodec, but it takes a lot of work to make an amigaos shared library version of it. I think the API is a lot different now too. It's beyond my skill set.

I've found that 800mhz is too slow for high definition and AVC/H-264 (and probably VP8/WebM) material, but fine for most other things, in mplayer, but not in ffplay (no acceleration).

ffplay is there just for completeness, and for those with fast enough machines to use it.
