• How to use hardware acceleration for ffmpeg [closed]

  11 mars 2024, par Kevin Gilbert

  I am try to get hardware acceleration going on my Dell Inspiron AMD laptop. It appears that vaapi is installed but how to I use it in ffmpeg ?

  


  For testing, all I want is to accelerate

  


  ffmpeg -i input.ts output.mp4


  


  Currently, the unaccelerated command I am currently using is

  


  ffmpeg -y -i input.ts -c:v libx264 -preset slower -tune film -filter_complex scale=1080:608 -sws_flags lanczos output.mp4


  


  BTW : Environment is fully up-to-date Fedora 39 with stock ffmpeg.

  


• Ffmpeg encoding too slow

  8 mars 2024, par Marc Cuadras

  I'm using a Python script to encode mp4 videos in various qualities, in my case 360 +720 +1080.
Ffmpeg encoding videos very slow, 1 video taking 2 hours or more, I'm using good dedicated server from hetzner (ryzen 5 3600 + 64gm ram), any suggestion to improve speed will be really appreciated

  looking for suggestion to improve encoding speed

  


• how to get exact position in video as image view ?

  16 février 2024, par Dhruvisha Joshi

  I want to give photo editing feature in my app. so I am allowing user to add text to photo and after that I want to convert it to video using Ffmpeg command.

  


  here is my command that adds text and convert photo to video.
ffmpeg -loop 1 -i /var/mobile/Containers/Data/Application/88F535C3-A300-456C-97BB-1A9B83EAEE7B/Documents/Compress_Picture/input.jpg -filter_complex "[0]scale=1080:trunc(ow/a/2)*2[video0];[video0]drawtext=text='Dyjfyjyrjyfjyfkyfk':fontfile=/private/var/containers/Bundle/Application/DE5C8DAA-4D66-4345-834A-89F8AC19DF9B/Clear Status.app/avenyt.ttf:fontsize=66.55112651646448:fontcolor=#FFFFFF:x=349.92:y=930.051993067591" -c:v libx264 -t 5 -pix_fmt yuv420p -y /var/mobile/Containers/Data/Application/88F535C3-A300-456C-97BB-1A9B83EAEE7B/Documents/Compress_Picture/output0.mp4

  


  here is my swift code to generate command.

  


  var filterComplex = ""
var inputs = ""
var audioIndex = ""

 // At least one element has isLocation set to true
 // Do something here

                            print("No elements have isLocation set to true")
                            inputs = "-i \(inputPath)"
                            audioIndex = "1"
                        }
