• How to statically build ffmpeg with librtmp without root on centos 6.4 ?

  22 avril 2014, par Shuman

  i forked STVS’s batch build script here. only added lines for rtmp ? but why it’s not working , the error i got is

  *** Building FFmpeg ***
  
  ERROR: librtmp not found

  if i check the config.log file

  gcc -D_ISOC99_SOURCE -D_FILE_OFFSET_BITS=64 -D_LARGEFILE_SOURCE -D_POSIX_C_SOURCE=200112 -D_XOPEN_SOURCE=600 -I/usr/tmp/tmp/ffmpeg-static-test/target/include -I/usr/tmp/tmp/ffmpeg-static-test/target/include -static --static -std=c99 -fomit-frame-pointer -pthread -I/usr/tmp/tmp/ffmpeg-static-test/target/include/opus -I/usr/tmp/tmp/ffmpeg-static-test/target/include -Wl,-z,relro -L/usr/tmp/tmp/ffmpeg-static-test/target/lib -c -o /var/tmp/ffconf.CIIzEs8o.o /var/tmp/ffconf.bBYD2amo.c

  /usr/bin/ld: cannot find -lssl
  
  collect2: ld returned 1 exit status
  
  ERROR: librtmp not found

  i then checked my openssl install, it’s installed and

  > which openssl
  
  /usr/bin/openssl
  
  
  
  
  
  > ldd /usr/bin/openssl
  
  linux-vdso.so.1 =>  (0x00007fffd19ff000)

  which means i have libssl.so already. i tried adding -L/usr/lib64 to the configure script, but still it’s not working.

  previously in the build script

  CFLAGS="-I$TARGET_DIR/include" LDFLAGS="-L$TARGET_DIR/lib -lm" ./configure --prefix=${OUTPUT_DIR:-$TARGET_DIR} --extra-cflags="-I$TARGET_DIR/include" --extra-ldflags="-L$TARGET_DIR/lib -lm" --extra-version=static --disable-debug --disable-shared --enable-static --extra-cflags=--static --disable-ffplay --disable-ffserver --disable-doc --enable-gpl --enable-pthreads --enable-postproc --enable-gray --enable-runtime-cpudetect --enable-libfaac --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-bzlib --enable-zlib --enable-nonfree --enable-version3 --enable-libvpx --disable-devices --enable-librtmp

  i tried

  CFLAGS="-I$TARGET_DIR/include" LDFLAGS="-L$TARGET_DIR/lib -L/usr/lib64 -lm" ./configure --prefix=${OUTPUT_DIR:-$TARGET_DIR} --extra-cflags="-I$TARGET_DIR/include" --extra-ldflags="-L$TARGET_DIR/lib -L/usr/lib64 -lm" --extra-version=static --disable-debug --disable-shared --enable-static --extra-cflags=--static --disable-ffplay --disable-ffserver --disable-doc --enable-gpl --enable-pthreads --enable-postproc --enable-gray --enable-runtime-cpudetect --enable-libfaac --enable-libmp3lame --enable-libopus --enable-libtheora --enable-libvorbis --enable-libx264 --enable-libxvid --enable-bzlib --enable-zlib --enable-nonfree --enable-version3 --enable-libvpx --disable-devices --enable-librtmp

  same error, what am i missing ?

• frame : allow align=0 (meaning automatic) for av_frame_get_buffer()

  8 février 2017, par Anton Khirnov

  frame : allow align=0 (meaning automatic) for av_frame_get_buffer()
  This will avoid every caller from hardcoding some specific alignment,
  
  which may break in the future with new instruction sets.

• avdevice/x11grab : rename the "w" Window to "root" in paint_mouse_pointer

  8 septembre 2014, par Antonio Ospite

  avdevice/x11grab : rename the "w" Window to "root" in paint_mouse_pointer
  This specifies better the meaning of the variable, and is also in
  
  preparation of a subsequent change which will introduce a temporary
  
  Window variable for which "w" is an good name.
