  • How to fix scrambled output

    26 janvier 2020, par Krishnakumar

    I am seeing the following scrambled output for a live stream when processing an udp input stream. I am using the recently downloaded ffmpeg from GIT. Stop and Start of ffmpeg command resolves the issues temporarily.

    Scrambled Out

    libavutil : introduce AVFilmGrainParams side data

    This patch introduces a new frame side data type AVFilmGrainParams for use
    
with video codecs which support it.
    

    It can save a lot of memory used for duplicate processed reference frames and
    
reduce copies when applying film grain during presentation.

  • how do i modify this ffmpeg build script for minimal binary size output

    13 janvier 2015, par Brian

    I’m trying to build the ffmpeg binaries for android on 3 chipsets. The output file size is too large to include in the project around 15mb.

    https://github.com/falnatsheh/ffmpeg-android is the github project repo

    the .sh build script for ffmpeg is like this

    #!/bin/bash
    

    
. abi_settings.sh $1 $2 $3
    

    
pushd ffmpeg
    

    
case $1 in
    
  armeabi-v7a | armeabi-v7a-neon)
    
    CPU='cortex-a8'
    
  ;;
    
  x86)
    
    CPU='i686'
    
  ;;
    
esac
    

    
make clean
    

    
./configure \
    
--target-os="$TARGET_OS" \
    
--cross-prefix="$CROSS_PREFIX" \
    
--arch="$NDK_ABI" \
    
--cpu="$CPU" \

--sysroot="$NDK_SYSROOT" \
    
--enable-pic \

--disable-doc \
    
--disable-shared \
    
--enable-static \
    
--pkg-config="${2}/ffmpeg-pkg-config" \
    
--prefix="${2}/build/${1}" \
    
--extra-cflags="-I${TOOLCHAIN_PREFIX}/include $CFLAGS" \
    
--extra-ldflags="-L${TOOLCHAIN_PREFIX}/lib $LDFLAGS" \
    
--extra-libs="-lm" \
    
--extra-cxxflags="$CXX_FLAGS" || exit 1
    

    
make -j${NUMBER_OF_CORES} && make install || exit 1
    

    
popd

    I tried adding —disable-everything as the first line in configure but then the compiler complains that I didnt set a target-os even though its the next line

    In the app I only use ffmpeg to take input mp4 videos and transpose and rotate them
    here are the two commands

    -y -i %s -vf transpose=%d -tune film -metadata:s:v rotate=0 -c:v libx264 -preset ultrafast -crf 27 -c:a copy -bsf:a aac_adtstoasc %s

    where %s is a file path

    and then concat files

    -y -i concat:%s -preset ultrafast -crf 27 -c:v copy -c:a copy -bsf:a aac_adtstoasc %s

    If someone can help me with the build script that would be awesome
