@dbermond

Thanks for your answer (and this package).

For context: I usually use ffmpeg-qsv, which is broken for me currently (I guess because of the latest intel-media-driver update). Whatever the case, I assumed this package will work, and it does, except for audio encoding.

My go-to line is

ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -i <in> -vf hwupload=extra_hw_frames=64,format=qsv' -c:v hevc_qsv -q 22 -c:a libfdk_aac -vbr 5 <out>

but libfkd_aac isn't available and bitrate limiting audio with another encoder (aac) doesn't seem to work, essentially rendering qsv unfeasible if you don't just pass through audio.

PS: Adding "--enable-libfdk_aac" to this PKDBUILD solved my issues.

@Schlaefer This is not the purpose of the package.

For this type of functionality (support for qsv + fdk_aac codecs), you should use another package like ffmpeg-full-git.

It would be nice if the build would include libfdk-aac.

@danboid I'm not sure about what you are referring as the 'foss qsv driver'. intel-media-sdk and intel-media-driver are already open source.

Regarding ffmpeg commands, this will work nice to encode something to h264 using qsv:

$ ffmpeg -i <input> -codec:a copy -codec:v h264_qsv -preset:v medium -rdo 1 -qscale:v 5 -look_ahead 0 -pix_fmt nv12 <output>

There are many ffmpeg options that you can use and tweak. Please refer to some specific forum for help on using ffmpeg command line.

Hi dbermond

Thanks for maintaining this PKGBUILD!

Have you considered creating a ffmpeg qsv PKGBUILD that doesn't use intel-media-sdk? Or, how would I modify this PKGBUILD to build ffmpeg using the FOSS qsv driver? I ask because I have read that the FOSS version of the qsv encoder is more forgiving regarding the input files than when using the official intel media libraries.

I'd also be interested to see any example ffmpeg commands for transcoding from one variety of 4K h264 to a qsv encoded 4K h264 file. I'm hoping that in doing so I can save some disk space. Ideally with both the decoding and encoding being qsv accelerated.

A working example of transcoding from 4K h264 to 1080 h264 using qsv would be great too, if you have one, as I think a lot of people would want to do that too.

Important note:

  • in short: the next time you update your system, use this command: # pacman -Syu intel-media-driver. If you're using intel-media-driver-git you're not affected and you can skip this note.

  • the long story: intel-media-driver is now in the [community] official repository (it is a dependency of intel-media-sdk, which in turn is a dependency of this package). intel-media-driver from the official repository changed the pkgver major number, causing it to be seen as a downgrade by pacman (and AUR helpers of course). This means that pacman will not automatically pull/install intel-media-driver from official repositories when you simply use the usual -Syu. You need to manually specify intel-media-driver alongside with the -Syu command as shown above.

I've fixed the package. It's now building fine.

There's been a change with hardening-wrapper that you'll need to address so ffmpeg-qsv-git installs properly.
