• Build libaacplus on Mac OS 10.9

  20 juillet 2020, par Thomas Ayoub

  I try to compile libaacplus using this (coming from FFMPEG website) :

  



  wget http://217.20.164.161/~tipok/aacplus/libaacplus-2.0.2.tar.gz
tar xzf libaacplus-2.0.2.tar.gz
cd libaacplus-2.0.2
sed -i '.bck' -e 's/libtool/glibtool/' autogen.sh
./autogen.sh
make
make install


  



  It fails at make step :

  I succeed to build when I was using 10.8.x but totally unable to do it with 10.9.x... Any clue ?

  



  Merry Christmas

  


• ffmpeg mp4 video cannot be played in old tv

  24 mai 2020, par Rick Brian

  I've convert many video to mp4 using ffmpeg and playing well on my TV.
  
But ever since I change my laptop to a new one, my conversion failed to load on the TV.

  



  I have tried to download old-stable ffmpeg Windows build, I tried also download a win-32 build, no good.
(I'm using x64 laptop with Windows 10 64-bit, just the same like previous laptop)
  
I also tried to add -pix_fmt yuv420p, still no good.

  



  This is code that I used to convert using ffmpeg :
  
ffmpeg -f concat -i "D:\Convert\LISTCAM.TXT" -c:v libx264 -c:a aac -pix_fmt yuv420p "Apr 2nd.mp4"

  



  I also tried to compare using ffmpeg -i between my playable mp4 file with new not-playable mp4,
  
both are just similar except the encoder header.

  



  Playable mp4 :

  Update :

  



  

  • I did a single-file input instead of a concatenation list.

  


  • I did a codec copy from a playable file, it works, but when I try to re-encode, it does not.
    
ffmpeg -i "Playable-video-file.mp4" -c:v copy -c:a aac "Output.mp4" this works

  


  



  ffmpeg -i "Playable-video-file.mp4" -c:v libx264 -crf 23 -profile:v main -level:v 3.0 -preset:v medium -c:a aac "Output.mp4" and this don't

  



  

  • I did the very same syntax and the same ffmpeg build on a friend's laptop with the same Windows 10 x64 architecture... the output file works fine and playable on my TV...

  


  • Friend's is Intel i5, mine is Intel i7
