• ffmpeg first segment does not have audio

  5 mars 2018, par Giorgi Peikrishvili

  I’m recording http stream using ffmpeg. Here is my command :

  ffmpeg -i https://tv-tbs-silk-front 1.adjara.com/4w/rustavi2hd/index.m3u8\?token\=376d9f864d81c7f85410ac5d3d0bde3dd6574daf-Hog86dAubE-1522939917-1520175117 -c copy -map 0 -bsf:a aac_adtstoasc -flags +global_header -f segment -segment_time 10 -force_key_frames 10 -segment_format_options movflags=+faststart -reset_timestamps 1 -strftime 1 %Y-%m-%d_%H-%M-%S.mov

  It makes segments as should be, but the only first segment does not have sound, others does.
  Any ideas about that ?

  Update as suggested in comments :
  Here is full output

  ffmpeg -i  -c copy -map 0 -g 10 -bsf:a aac_adtstoasc -flags

• Shifting overlay position every x seconds

  11 novembre 2019, par David Tran

  Currently, I add a watermark to the bottom right of my video to prevent others from republishing it. However, they blur the watermark so I’m thinking of adding a moving watermark that changes its position every x seconds.

  Below is my current ffmpeg command :

  ffmpeg -i input.mp4 -i logo.png -filter_complex "[1][0]scale2ref=iw/4:ow*90/272[wm][vid];[vid][wm]overlay=W-w-W*10/100:H-h-H*5/100" -preset veryfast output.mp4

  How can I make the watermark position from the bottom right to top right, to top left, and bottom left every 30 seconds ? Thank you.
