• error while compiling x264 in linux

  14 avril 2011, par kartul

  Hey all I'm trying to compile x264 under linux (x64). But it keeps throwing me an error. I've googled around but found nothing. Here's the commandline history:

  spin@around:~/x264$ git clone git://git.videolan.org/x264.git

  If you really want to compile without asm, configure with --disable-asm.

• open source examples of use of x264 lib with directshow mobile ?

  6 avril 2011, par Blender

  Where to find open source examples of use of x264 (or any other h264 encoding lib) with directshow on windows mobile? (for example to record video from camera in the mobile phone where h264 is not supported by default into h264)

• mencoder -> x264 : FPS problem : Video is 2x faster at the output

  28 mars 2011, par Julien Palard

  I got an input video, ffmpeg says about it : 29.96FPS 59.75 tbr 1k tbn 59.83 tbc My process to encode is :

  $ mencoder input_video -vf dsize=480:320:0,scale=0:0,expand=480:320,dsize=1.5,format=i420 -of rawvideo -ofps 25 -ovc raw -nosound -o output.yuv
  $ x264 input_video --profile baseline --fps 25 [blahblah] -o output
  $ MP4Box -add output.yuv -fps 25 output.mp4
  

  Im'simplificating a lot here to let you parse less as I'm encoding the audio apart and merging the result using mp4box.

  ffmpeg -i output says that the vid is : 25 FPS 25 tbr 25 tbn 50 tbc

  And while playing the video, the audio is normal, the video is 2x faster than input, so the video ends at the half of the audio track (compared to the input, the audio is good, it's just the video running 2x faster)

  Any idea about my problem ?

• video streaming - mp4 file (x264) - and skip to location

  14 mars 2011, par Raoul

  Previously I was using apache to serve .flv files which an embedded player on an intranet page was playing.

  Is it possible to stream mp4 files (x264 encoded) in a similar manner? Are there any open source scripts/solutions for doing proper streaming (e.g. people can skip to skip to a part of the video without having to download the parts they've skiped over)?

  If anyone is doing someting similar I'd love to hear from them

  Thanks

• redhat - compile ffmpeg - how to link with liblame/x264 when they're installed locally

  23 février 2011, par Raoul

  I've managed to install ffmpeg, a basic build using

  ./configure --disable-debug --disable-network --disable-ffserver --disable-ffplay --prefix=/export/home/userid/bin/ffmpeg
  

  Now I've installed liblame and x264 to /export/home/userid/bin and tried to compile ffmpeg as follows:

  ./configure --disable-debug --disable-network --disable-ffserver --disable-ffplay --prefix=/export/home/userid/bin/ffmpeg --enable-libmp3lame  --enable-libx264 --enable-gpl
  

  And I get the error

  ERROR: libmp3lame not found
  

  How can I tell configure to look for things in /export/home/bin?

  Thanks
