• how to reencode with ffmpeg (with limited x264)

  26 mai 2012, par sarfraz

  Until now I used this script to reencode my rips for my box (tv decoder) :

  ^_^ ( ~ ) -> cat ~/++/src/convert.sh 
  
  #! /bin/bash
  
  
  
  name=$(path -r "$1") # it gives the file name without the extension
  
  
  
  [ "$1" = *.mp4 ] && ffmpeg -i "$name".mp4 -vcodec copy -acodec copy "$name".mkv
  
  x264 --preset veryfast --tune animation --crf 18 --vf resize:720,576,16:15 -o "$name".tmp.mkv "$name".mkv
  
  mkvmerge -o "$name [freeplayer sd]".mkv "$name".tmp.mkv --no-video "$1"
  
  rm -rf "$name".tmp.mkv
  
  [ "$1" = *.mp4 ] && rm -rf "$name".mkv
  
  exit 0
  
  
  
  #EOF

  It works on my ubuntu and archlinux laptops. But it doesn’t on my desktop witch runs fedora.
  Google says that the x264 package shiped by rpmfusion doesn,t support lavf and ffms2.
  And I cannot unistall it because smplayer (witch i like) needs it.

  Ok, so I have to compile it. Google then says "you have to build ffmpeg, ffms2 tnen x264 ensuring that the flags are correctly refered." Well, didn’t work (ffms2 cannot find LIBAV - even when I am telling where - and x264 does’t configure with lavf...)

  My question is : can I use ffmpeg alone to do what my script does.
  I have ffmpeg version 0.8.11, x264 0.116.2048 59cb2eb and gcc : 4.6.1 20110804 (Red Hat 4.6.1-7)

  Any hint wound be appreciated.

  EDIT : Ok, I found that : ffmpeg -i input file -acodec copy -vcodec libx264 -preset veryfast -tune animation [that part I don’t have] output

  PS : english is not my native, plz forgive any spelling fault.

• Windows : can't generate libx264.dll because MinGW : not c compiler found

  21 avril 2015, par Sandie C

  It’s my first post in a forum ever (and in english...) Any suggestion is welcomed.

  So let’s started !

  My global goal is to recorder/transcoding and dispay an IP Camera stream from a .bat whitch calling vlc. (I tried before doing it with VLC interface and it’s going well. I don’t understand why the encoder is missing using that way)

  I want an asf container containing h264 and aac.

  ---

  .bat :

  cd C :\Program Files (x86)\VideoLAN\VLC

  vlc rtsp ://root:root@ip_adresse/media.amp —sout "#transcode vcodec=x264, vb=112 , acodec==aac, fps=25:duplicatedst=display,dst=standardaccess=file,mux = asf,dst=flux.asf" -v

  ---

  when I first execute this, VLC told me that H264 encoder was not found, so I decided to compile x264.

  I used this link

  http://www.ayobamiadewole.com/Blog/How-to-build-x264-or-libx264.dll-in-Windows

  I succeed to make the .exe but and when I got to

  ./configure —disable-cli —enable-shared —extra-ldflags=-Wl,—output-def=libx264.def

  minGW shell indicates : not working c compiler found

  I tried to find some answer, but i didn’t found a good one.

  Does anyone have an idea of what i’m doing wrong ?

  Is it possible that my gcc (4.6) is not the good one ? What should I do ?

  Need another advice :
  When I would have this libx264.ddl where should I put it to make my script working ?

  Early thanks for your answers.
