• Trying to compile x264 and ffmpeg for iPhone - "missing required architecture arm in file"

  4 août 2012, par jtrim

  I'm trying to compile x264 for use in an iPhone application. I see there are instructions on how to compile ffmpeg for use on the platform here : http://lists.mplayerhq.hu/pipermail/ffmpeg-devel/2009-October/076618.html , but I can't seem to find anything this complete for compiling x264 on the iPhone. I've found this source tree : http://gitorious.org/x264-arm that seems to have support for the ARM platform.

  Here is my config line :

  ./configure —cross-prefix=/usr/bin/ —host=arm-apple-darwin10 —extra-cflags="-B /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/ -I /Developer/Platforms/iPhoneOS.platform/Developer/SDKs/iPhoneOS3.2.sdk/usr/lib/"
  

  ...and inside configure I'm using the gas-preprocessor script (first link above) as my assembler :

  gas-preprocessor.pl gcc
  

  When I start compiling, it chunks away for a little while, then it spits out these warnings and a huge list of undefined symbols :

  ld : warning : option -s is obsolete and being ignored
  ld : warning : -force_cpusubtype_ALL will become unsupported for ARM architectures
  ld : warning : in /usr/lib/crt1.o, missing required architecture arm in file
  ld : warning : in /usr/X11R6/lib/libX11.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libm.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libpthread.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libgcc_s.1.dylib, missing required architecture arm in file
  ld : warning : in /usr/lib/libSystem.dylib, missing required architecture arm in file
  Undefined symbols :
  

  My guess would be that the problem has to do with the "missing required architecture arm in file" warning...any ideas ?

• FFmpeg video encoding from iPhone to URL

  20 septembre 2016, par Nicolai Harbo

  I ran into a problem - I’m building an app, which I would like to be able to livestream. I have found a supplier, that I want to use - "all" he needs me to do, is to encode the video from the camera, to ffmpeg, and call his API. The thing is, I have no clue how to encode the video to ffmpeg. I have tried several google searches, and lots of different SDK’s for videostreaming, but it doesnt seem to help in my case.

  I know about Wowza and other livestream providers, but they cant deliver what I want, so I think this is my last option.
  So if any of you guys out there, can help me with encoding video from the camera into ffmpeg and send it to a API, please let me know how :-)
  It could be, that there’s a pod out there that i’ve overseen..

  Thanks in advance,
