  • Compiling ffmpeg for Android on OSX

    16 février 2021, par Tim Autin

    I'm trying to compile ffmpeg for Android, on OSX 10.12.4 .

    



    Here are the steps I followed :

    



    1°) Compile pkg-config

    



    Download the sources from here . Extract && cd in the pkg-config folder.

    



    export DST=/a/path/on/my/computer

./configure --with-internal-glib --prefix=$DST --exec-prefix=$DST
make -j2
make install

export PATH=$PATH:$DST/bin


    



    2°) Compile ffmpeg

    



    Download the sources from here. Extract && cd in the ffmpeg folder.

    



    export NDK=/path/to/android-ndk-r15c
export PLATFORM_VERSION=android-26
export ARCH=arm
export PLATFORM=$NDK/platforms/$PLATFORM_VERSION/arch-$ARCH
export TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64

export PREFIX=$(pwd)/android/$ARCH

export ADDI_CFLAGS="-Os -fpic -marm"
export ADDI_CONFIGURE_FLAG=""
export ADDI_LDFLAGS=""

./configure \
  --prefix=$PREFIX \
  --enable-shared \
  --disable-static \
  --disable-doc \
  --disable-ffmpeg \
  --disable-ffplay \
  --disable-ffprobe \
  --disable-ffserver \
  --disable-symver \
  --disable-avdevice \
  \
  --pkg-config=pkg-config \
  \
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  --target-os=linux \
  --arch=$ARCH \
  --enable-cross-compile \
  --sysroot=$PLATFORM \
  --extra-cflags="$ADDI_CFLAGS" \
  --extra-ldflags="$ADDI_LDFLAGS" \
  \
  $ADDI_CONFIGURE_FLAG

make -j2


    



    Make fails with the following error :

    I'm able to fix that error by renaming B0 & B1 variables in the source to A0 & A1 (don't know why it fixes the problem), but then it fails somewhere else. I guess something is wrong in my config, and I'd prefer to avoid having to patch the source.

    



    So the questions are :

    



      

    • does someone know what's wrong here ? Do I need to give some args to gcc ?
    • 


    • is the —target-os=linux correct, or should it be —target-os=darwin ? Is target-os the OS where the compilation is done, or where ffmpeg will be executed ? By using darwin, I can compile using —enable-static, but not —enable-shared (which I want).
    • 


    



    Note : I need to compile it myself as I want only an arm version, with HTTPS support. Thus I can't use the existing built versions.

    


  • MP4 file starts from a non-key frame [closed]

    1er octobre 2023, par userDtrm

    I have used the following ffprobe command to analyse a .mp4 file.

    


    


    ffprobe -i <input /> -show_frames - select_streams v:0 -print_format flat &amp;> save_to_file.text

    &#xA;

    &#xA;

    It produces the following output.

    &#xA;

    As seen in this output, the 1st frame appears to be a P frame. I'm curious as to how will the decoder decode this frame without a preceding I frame (key frame) ? The P frame will not have enough information to reconstruct the image from its residual data without the key frame.

  • Stream specifier ':a' in filtergraph description [0:v][0:a][1:v][1:a]concat=a=1:n=2:v=1[s0][s1] matches no streams

    6 septembre 2022, par Mash

    I am using ffmpeg-python and I am trying to make a code that gets all the clips from a folder, converts all of them to the same format then merge all of them with their audio to one final video file.

    &#xA;

    Here is how the python script looks like

    &#xA;

    import os&#xA;import ffmpeg&#xA;&#xA;dir = "./clips/"&#xA;&#xA;# Reshape video&#xA;for f in os.listdir(dir):&#xA;  (&#xA;    ffmpeg&#xA;    .input(os.path.join(dir, f))&#xA;    .filter("scale", size="hd1080", force_original_aspect_ratio="increase")&#xA;    .filter(&#x27;fps&#x27;, fps=60, round=&#x27;up&#x27;)&#xA;    .output(str(os.path.join(dir, f))[:-4] &#x2B; "_reshaped.mp4")&#xA;    .run()&#xA;  )&#xA;&#xA;# Select reshaped video&#xA;files = []&#xA;&#xA;for f in os.listdir(dir):&#xA;  if "_reshaped.mp4" in str(os.path.join(dir, f)):&#xA;    files.append(ffmpeg.input(str(os.path.join(dir, f))))&#xA;&#xA;# eparate video and audio, then flat the array&#xA;video_and_audios_files = [item for sublist in map(lambda f: [f.video, f.audio], files) for item in sublist]&#xA;&#xA;# concat all&#xA;joined = (&#xA;    ffmpeg&#xA;    .concat(*video_and_audios_files, v=1, a=1)&#xA;    .node&#xA;)&#xA;&#xA;# merge video and audio&#xA;(&#xA;    ffmpeg&#xA;    .output(joined[0], joined[1], "./out.mp4")&#xA;    .run()&#xA;)&#xA;&#xA;

    &#xA;

    Now here is my output, this is the output of the part of the code that merges every clip into one (aka the merge video and audio section of the code)
