Changer son thème graphique
22 février 2011, parLe thème graphique ne touche pas à la disposition à proprement dite des éléments dans la page. Il ne fait que modifier l’apparence des éléments.

Enable QSV for FFmpeg with directshow input and JPEG image sequence output
10 mars 2020, par clicI’m using FFmpeg with Directshow input. The output is a series of single JPEG images. FFmpeg itself maps the stream to mjpeg and uses image2 for the output.
Is it possible to increase performance by using the Intel QuickSync Video (QSV) hardware acceleration for this process ? The FFmpeg QuickSync Wiki actually lists JPEG encoding since Braswell.
This is what I tried so far :
ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -f dshow -video_size 3840x2160 -framerate 25 -i "video=My Webcam" -vf hwupload=extra_hw_frames=64,format=qsv -vcodec mjpeg_qsv "C:\out\%d.jpg"
The command works, images are generated - but the GPU load seems to be the same as without any qsv options..?
Thanks !

ffmpeg : Concat multiple mp4 with no audible delay between clips
16 novembre 2014, par GeuisI have several dozen mp4 clips that all have the same resolution, codecs, etc. I’m trying to combine them into a single file using ffmpeg, but there always seems to be a slight audio delay between the clips. My problem is that I’d like them to be seamless.
Been following the steps here, https://trac.ffmpeg.org/wiki/How%20to%20concatenate%20(join,%20merge)%20media%20files
There’s always a slight delay between the files, which is especially noticeable in the audio.
Is there a recommended way to merge video files with no delay between them ?
