• To convert the extension of a file to the different directory by a ffmpeg command

  13 mars 2018, par user27240

  The command below is to convert from mp4 file to jpg file with the same file name in the same directory, .../httpdocs/save/.

  [root@server-xxxxx-x ~]# for i in `find /var/www/vhosts/xxxxxx.com/httpdocs/save/ -type f -name "*.mp4"`; do ffmpeg -i $i `echo $i | sed -En "s/.mp4$/.jpg/p"`; done

  Now, I need to convert from, .../httpdocs/save/ to the different directory, .../httpdocs/file/, how should I change the command above ? I’d appreciate if anyone could help me out.

• Convert file with any extension to MP4 with ffmpeg

  15 novembre 2019, par not legit

  I am using youtube-dl and ffmpeg to create a youtube downloader and converter (for personal use). I am trying to download a video and convert it to MP4.

  The problem I have, is that youtube-dl downloads the video in a variety of formats. Is there a way that I can download the video and then tell FFMPEG to convert it, not knowing the current file type ?

  I tried using a * wild card but that results in an error.

  @echo off
  
  title youtube downloader
  
  
  
  set /p name= URL: 
  
  echo Select a type. (vid/mp3/mp4)
  
  set /p type=
  
  
  
  IF /i "%type%"=="vid" goto vid
  
  IF /i "%type%"=="mp3" goto mp3
  
  IF /i "%type%"=="mp4" goto mp4
  
  
  
  :vid
  
  youtube-dl %name%
  
  goto commonexit
  
  
  
  :mp3
  
  youtube-dl -x --audio-format mp3 %name%
  
  goto commonexit
  
  
  
  :mp4
  
  youtube-dl -o video %name%
  
  ffmpeg -i video.* video.mp4 -hide_banner
  
  
  
  :commonexit

• lavu : add/use flag for RISC-V Zba extension

  lavu : add/use flag for RISC-V Zba extension
  The code was blindly assuming that Zbb or V implied Zba. While the
  
  earlier is practically always true, the later broke some QEMU setups,
  
  as V was introduced earlier than Zba.
