I don't have vulkan here but that's what I use with QSV. Maybe it is
an inspiration to you:
ffmpeg -video_size "$resolution"\

Hello there
I'm on Windows 10 with ffmpeg and I would like to make a video (a slide) with a
bunch of jpeg files and an mp3 music file.
I tried first
cat *.JPG | ffmpeg -y -f image2pipe -framerate 1 -i SligoAir_WhiteBlanket.mp3
-vsync vfr -pix_fmt yuv420p -movflags +faststart output.mkv
with fail
ffmpeg -video_size "$resolution"\

Because this is a generic script not limited to 1080p. That way I can
use it for 4k as well what is not possible with level 4.2.
Furthermore, with x
oki, cool. i dont know how ffmpeg deals x11 capture, i thought probing is
used only on mpeg streams.

And if I Would like to have each image shown during 15 seconds (I have 15
pictures and whants the total time being 225 sec), How should I specified the

Hello,
is it possible to compile ffmpeg to include only support for AAC-LC
profile support from the whole AAC decoder?

Hi you lovely people,
I have an error caused when I use the aresample filter that I think has
something to do with the position of the filter in the chain.
Failed to inject frame into filter network: I/O error
The system takes a variety of different source configurations so I have some
code that
I have 15 JPEG file to be used for a slide (duration: 135 sec): Each image is

AAC-LC is patent free at this point in US. AAC-Main in theory could be a
patent free in December 2020 as the corresponding standard

even if there's no config options, one can aways edit sbr routines in some
way in (fdk)aac sources to castrate support of HE profile...

Hello again,
maybe someone could help a ffmpeg-newbie to get the correct hls-settings
(hope there is something possible without re-encoding). The GOP is
IPP 31 CLOSED (got it from this script
https://gist.github.com/ragnraok/638023456771dc596e6f953b47061f0e).
Thanks,
