save in ffmpeg-2.8.22.tar.gz
use tar -zxvf ffmpeg-2.8.22.tar.gz get FFmpeg-2.8.22 folder
change folder cd FFmpeg-2.8.22

  • 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

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

    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 ?

  • Cut .mkv Video using ffmpeg without changing original bitrate

    23 janvier 2021, par benito_h

    I accidently said an unappropriate swear word during an educational video (good start I know). So I would like to remove this section from the .mkv video. However I would like the video and audio bitrate and quality unchanged.

    


    First, I tried cutting the video slightly after the relevant time stamp without reencoding it, using for example

    


    ffmpeg -i input.mkv -ss 00:01:09.200 -c copy -t 4:11 output.mkv


    


    but this way the first couple of seconds seem to get lost.

    


    Is there a way to remove the relevant segment (01:08.800 to 01:09.200) while maintaining the same bitrate / quality for audio and video ? Since only formulas are shown, a slight out-of-sync wouldnt even matter.
