video audio encoding


Versions (?)

merge one slide , audio using ffmpeg - output is AUDIO ONLY in video container ( one slide in vid track)


 / Published in: Bash
 

podcast to youtube . the output will upload ok using mpeg container for audio only 2 examples: 2 pass libx264 output .wmv file

  1. =============== 2 pass libx264 example outputs mp4 file with low video bandwidth
  2.  
  3. ./ffmpeg -y -loop_input -shortest -i test_album_cover.png -i rec_1448.3gpp -pass 1 -vframes 500 \
