24 août 2024, par Rok BenkoI'm trying to install ffmpeg via vcpkg on Windows by running the following command :


vcpkg.exe install ffmpeg


The installation throws an error when getting CMake variables for x64-windows.

What does this error mean ? The suggested

PS : I opened logs, but I have no idea how to solve the error. I don't understand them.

As you can see, these audio streams are single channel as each stream is mapping to a unique channel.


I want to combine these audio streams into a aac file such that the output has the channel information retained.


I use the following command to do this :


ffmpeg -i -filter _complex "[0:a:0][0:a:1][0:a:2][0:a:3][0:a:4][0:a:5][0:a:6][0:a:7]join=inputs=8:channel_layout=7.1[aout]" -map "[aout]" -c:a aac output_audio_join.aac


The individual audio streams were having a duration of duration=103.728625 seconds.


The output however is 862.207660 seconds. Why ?

ffmpeg : Strange behaviour with fade-in and fade-out in conjunction vs successively
29 novembre 2023, par CErI have a video file I want to fade in and out over a duration of three seconds each.


My code is :


ffmpeg -i video.mp4 -vf "fade=t=in:st=0:d=3,fade=t=out:st=169.288000:d=3" videofaded.mp4


Expected behaviour : Fade from and to black over 3s.
What I get : No fade in at all but a fade out as specified.


If I run
ffmpeg -i video.mp4 -vf "fade=t=in:st=0:d=3" -c:a copy fadein.mp4
to juste fade in everything works as expected.

Can anybody help my identify the problem ? I want to fade in and out in the same turn as there are a couple of videos to edit.


Thanks,
Chris
