  • how is the 'response' parameter calculated for rtsp authentication ?

    11 septembre 2015, par zcaudate

    So I’ve captured a couple of packets from ffmpeg to a ip camera with rtsp, which I’ve attached at the end of the question :

    In the second request/response pair, the protocol sees that it needs authentication and returns a nonce="be129bc71fa3ddfbff9989ed6f748268" to the user

    In the third request/response pair, there is a response="da0882d360a56deef2994d8ba0de8e89" being sent to the server and I’m not sure how that is generated. The user/password pair is admin with a blank password.

    Any ideas of where to look in the RFCs would be great

  • ffmpeg is failing to convert mov files from iPhone 4

    It’s only happening for mov files. There are couple of tricky places it looks like it’s trying to take screenshot from a video.

    Maybe anyone witnessed anything similar and can give me a tip ?

  • Reduce compiled ffmpeg library size based on what I need

    20 septembre 2014, par Alin

    I finally managed to build ffmpeg as detailed in here : https://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/ and in the end, I have a ffmpeg library which accepts command arguments.

    I am ONLY applying a watermark image over the video so for it I am using this ffmpeg command :

    ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi

    Basic config :

      ./configure \
    
    --prefix=$PREFIX \
    
    --disable-shared \
    
    --enable-static \
    
    --disable-doc \
    
    --disable-ffmpeg \
    
    --disable-ffplay \
    
    --disable-ffprobe \
    
    --disable-ffserver \
    
    --disable-doc \
    
    --disable-symver \
    
    --enable-protocol=concat \
    
    --enable-protocol=file \
    
    --enable-muxer=mp4 \
    
    --enable-demuxer=mpegts \
    
    --enable-memalign-hack \
    
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    
    --target-os=linux \
    
    --arch=arm \
    
    --enable-cross-compile \
    
    --sysroot=$SYSROOT \
    
    --extra-cflags="-Os -fpic -marm $ADDI_CFLAGS" \
    
    --extra-ldflags="$ADDI_LDFLAGS"

    No other commands needed from ffmpeg.

    When compiling ffmpeg I get these files :

    enter image description here

    I want to reduce the size of the library to as small as possible, so given the above command, are there any files that I can remove from final build ?

    ALSO which is the most common CPU found in current devices ? arm v7vfpv3, arm v7vfp, arm v7n ? I want to cover as many devices as possible.
