• ffmpeg convert images to video and add audio in one command

  9 novembre 2022, par user2108258

  I have two commands that I would like consilidate to a 1 liner.
Here are the two queries.

  


  Here are the steps i need help

  


  

  1. create a video based on a directory of jpegs

  


  


  ffmpeg -f image2 -pix_fmt yuv420p -r 10 -s 1080x1920 -i 'Roach spray high-25263/%d.jpg' -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -crf 25 -vcodec h264 'Roach spray high.mp4' -y


  


  

  2. Merge audio with video from step 1

  


  


  ffmpeg -stream_loop -1 -i 'Roach spray high.mp4' -i '/beats/2022/Roach spray high.mp3' -shortest -map 0:v:0 -map 1:a:0 '/videos/Roach spray high/Roach spray high.mp4' -y


  


  Is there a way to combine these two steps into 1 ?

• How to correctly use h264_amf on Windows ?

  27 octobre 2022, par Harshiv

  I'm trying to use hardware encoding with FFMPEG on Windows 10 with AMD Radeon r5 M330 DGPU on laptop : HP-AC026-TX. FFMPEG version is 5.1.2-full_build-www.gyan.dev from gyan.dev. I'm using this :

  


  fmpeg ^
    -hide_banner ^
    -v verbose ^
    -i "%1" ^
    -c:v h264_amf -acodec copy -y out.mp4


  


  but it fails with :

  


  [h264_amf @ 000001fb84d80b80] AMF initialisation succeeded via D3D11.
[h264_amf @ 000001fb847ab3c0] CreateComponent(AMFVideoEncoderVCE_AVC) failed with error 36
Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height


  


  The arguments seem as generic as I could hope, FFMPEG should use sensible defaults, so I can't Understand why it is failing.
Entire FFMPEG output is :

  What should I do to make hardware encoding work ?
