• ffmpeg options for playing in iPad WebView with tag

  19 septembre 2013, par Waynn Lue

  I'm trying to convert a video to be played in a tag in a WebView in iOS. I've tried the options at this link but it still doesn't seem to play. I've found videos that do successfully play, though, so I'm sure it's possible, I just can't seem to get any working. Here's the ffmpeg -i output for something that works.

  Here's what I tried from the wiki :

  ffmpeg -i {filename} -acodec aac -ac 2 -strict experimental -ab 160k -vcodec libx264 -preset slow -profile:v baseline -level 30 -maxrate 10000000 -bufsize 10000000 -b 1200k -f mp4 -threads 0 {filename}.ipad.mp4

  But the file doesn't play in the WebView.

• ffmpeg overlay not showing on first frame

  5 mai 2016, par Nic Wilson

  I’m trying to use ffmpeg to overlay a 720x720 video (previd.mp4) onto a background image (bg.jpg). I have it working except that the first frame of the video that is created shows the background only for a frame before the overlay video is shown on top of it.

  This is what I’m using to create the video and overlay :

  ffmpeg -loop 1 -i bg.jpg -i previd.mp4 -filter_complex "[1:v]scale=-1:1080[a]; [0:v][a]overlay=(main_w/2)-(overlay_w/2):0:shortest=1[video]" -map "[video]" -map 1:a -codec:a copy vid.mp4

• how to encode 25fps

  20 novembre 2020, par Vadik Jony

  i am not a programmer, but a part of my job is recoding. The person befor me left a script that recodes videos.
THE CURRENT PROBLEM : i need to add to the script the line to recode any video to 25 fps. I tried adding -filter:v fps=fps=25 to the script and it works BUT it ignores all other recoding settings. So i would be very happy if someone could help. Sorry for my trivial language, as i said - i am not a programmer :(
HERE IS THE SCRIPT :
