• Android with pthread_cancel enabled ? ffmpeg depends on pthread_cancel

  12 mars 2014, par Whoami

  I am building ffmpeg 2.1.3 in the android with ndk r9b version.

  I have used the below command.

  ./configure --enable-shared --prefix=/home/fbuild 
  
               --cross-prefix=arm-linux-androideabi- 
  
               --enable-cross-compile 
  
               --target-os=linux --arch=arm --enable-gpl 
  
               --enable-libx264 --extra-cflags=-I/home/fbuild/include 
  
               --extra-ldflags=-L/home/fbuild/lib --disable-doc 
  
               --disable-ffmpeg --enable-network --disable-ffplay 
  
               --disable-ffprobe --disable-ffserver --enable-avresample 
  
               --enable-decoders 
  
               --enable-encoders 
  
               --enable-muxers 
  
               --enable-demuxers 
  
               --enable-parsers --enable-protocols --enable-filters 
  
               --enable-avresample --disable-indevs --enable-indev=lavfi 
  
               --disable-outdevs --enable-hwaccels --enable-libx264 
  
               --enable-zlib --enable-muxer=md5 --enable-runtime-cpudetect  
  
               --cpu=cortex-a8 
  
               --enable-pthreads --enable-static

  in config.log

   main:ffconf.82qqjSTF.c(.text+0x4): error: undefined reference to '**pthread_cancel**

  Which clearly indicates, pthread_cancel is unavailable.

  Is it an existing issue, or do we have a any other solution for the same ?

  I have enabled '—enable-pthreads',

  I am trying to stream RTSP Stream through, UDP

  Your help is much appreciated. Thanks.
