• Got error (input/output error) during tcp opening, FFMPEG

  1er juin 2012, par manutd

  I got error during tcp opening.
  Exactly to say, avformat_open_input always return -5 (input/output error).
  I looked into the source of the error code using gdb and found that getaddrinfo(in libavformat/tcp.c) function didn't work well as expected and returned the error value EIO.
  ffmpeg source have ff_getaddrinfo(in libavformat/os_support.c) function that is linked to getaddrinfo but when I run the program and my program encountered getaddrinfo, my program called other function in libc.so, dynamic library. I couldn't find which function is called.
  I gave the valid url to ffmpeg. The valid url is "http://stream.radiojavan.com/radiojavan".

  I compiled ffmpeg source for Android-use and used ffmpeg version 0.8.1
  This is my configuration.

  ./configure --target-os=linux \
  
      --prefix=$PREFIX \
  
      --enable-cross-compile \
  
      --extra-libs="-lgcc" \
  
      --arch=arm \
  
      --cc=$PREBUILT/bin/arm-linux-androideabi-gcc \
  
      --cross-prefix=$PREBUILT/bin/arm-linux-androideabi- \
  
      --nm=$PREBUILT/bin/arm-linux-androideabi-nm \
  
      --sysroot=$PLATFORM \
  
      --extra-cflags=" -O3 -fpic -DANDROID -DHAVE_SYS_UIO_H=1 -Dipv6mr_interface=ipv6mr_ifindex -fasm -Wno-psabi -fno-short-enums  -fno-strict-aliasing -finline-limit=300 $OPTIMIZE_CFLAGS " \
  
      --disable-shared \
  
      --enable-static \
  
      --extra-ldflags="-Wl,-rpath-link=$PLATFORM/usr/lib -L$PLATFORM/usr/lib -nostdlib -lc -lm -ldl -llog" \
  
      --disable-ffplay \
  
      --enable-zlib \

  Any advise would be appreciated.

• Compile ffmpeg for armv7s

  14 août 2014, par user3929400

  I am trying to compile ffmpeg on OSX 10.9. I want to use the ffmpeg framework in an iOS testapplication using xCode.

  I want to link the libfaac to ffmpeg and compile it for armv7s. When I follow the compilation guide (https://trac.ffmpeg.org/wiki/CompilationGuide/MacOSX) on the ffmpeg site, it does not work.

  I used the following configuration :

  ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --arch=armv7s

  Another configuration I tried is

  ./configure  --prefix=/usr/local --enable-gpl --enable-nonfree --enable-libass --enable-libfdk-aac --enable-libfreetype --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libx264 --enable-libxvid --arch=armv7s --enable-cross-compile --target-os=darwin

  The difference between both configuration is the cross compile and target os.

  Both configuration produces the following error message :

  GNU assembler not found, install gas-preprocessor

  Although, I have copied gas-preprocessor.pl into the directories /usr/local/bin and /usr/bin and modified the file read-write props by using chmod +x gas-preprocessor.pl

  Can somebody help me to configure ffmpeg by giving for example an example configuration which does work ?
