• Building x264 on a Mac for android “No working C compiler found”

  20 novembre 2015, par LostPuppy

  I am trying to build x264 and eventually use it to build ffmpeg the following is my script :

  #!/bin/bash
  
  
  
  NDK="/Users/account/Documents/FFmpeg/android-ndk-r10e"
  
  TOOL_DIR_ARM="/Users/account/Documents/FFmpeg/android-ndk-r10e/sources/ffmpeg-2.8.2/my-android-toolchain"
  
  SYSROOT=$NDK/platforms/platforms/android-21/arch-arm
  
  echo "removing tool chain directory if it exists"
  
  rm -r $TOOL_DIR_ARM
  
  
  
  $NDK/build/tools/make-standalone-toolchain.sh \
  
      --platform=android-21 \
  
      --arch=arm \
  
      --install-dir=$TOOL_DIR_ARM \
  
      --toolchain=arm-linux-androideabi-clang3.6\
  
      --llvm-version=3.6 \
  
      --system=darwin-x86_64
  
  
  
  if [ -d $SYSROOT ]; then
  
      echo "$SYSROOT is a valid directory"
  
  fi
  
  
  
  function build_x264
  
  {
  
  cd x264
  
  
  
  # another build for phone
  
  ./configure \
  
  --cross-prefix=arm-linux-androideabi- \
  
  --sysroot=$SYSROOT \
  
  --host=arm-linux \
  
  --enable-static \
  
  --enable-pic \
  
  --disable-cli 
  
  
  
  make -j4
  
  make install
  
  
  
  cd ../
  
  }
  
  
  
  
  
  function build_one
  
  {
  
  cd 
  
  
  
  # another build for phone
  
  ./configure \
  
  --sysroot=$SYSROOT \
  
  --target-os=linux \
  
  --arch=arm \
  
  --cross-prefix=$TOOL_DIR_ARM/bin/arm-linux-androideabi- \
  
  --cc=$TOOL_DIR_ARM/bin/clang \
  
  --enable-cross-compile \
  
  --enable-encoder=mpeg4 \
  
  --enable-pthreads \
  
  --enable-gpl \
  
  --enable-libx264 \
  
  --enable-pic \
  
  --extra-cflags='-I/usr/local/include' \
  
  --extra-ldflags='-L/usr/local/lib'
  
  
  
  make clean
  
  make -j4
  
  make install
  
  
  
  }
  
  echo "Building x_264 library"
  
  build_x264
  
  echo "Building FFmpeg"
  
  build_one

  I get an error saying

  No working C compiler found.
  
  Makefile:3: config.mak: No such file or directory

  The following is the output from the config.log file

  checking for -mdynamic-no-pic... yes
  
  checking for -arch x86_64... yes
  
  x264 configure script
  
  
  
  checking whether gcc works... yes
  
  checking whether gcc supports for( int i = 0; i < 9; i++ ); with -std=gnu99... yes
  
  checking for -mpreferred-stack-boundary=5... no
  
  Failed commandline was:
  
  --------------------------------------------------
  
  gcc conftest.c -m64 -Qunused-arguments -Wall -I. -I$(SRCPATH) -mdynamic-no-pic -arch x86_64 -std=gnu99  -mpreferred-stack-boundary=5  -m64  -lm -arch x86_64$
  
  clang: error: unknown argument: '-mpreferred-stack-boundary=5'
  
  --------------------------------------------------
  
  Failed program was:
  
  --------------------------------------------------
  
  int main (void) {  return 0; }
  
  --------------------------------------------------
  
  checking whether yasm supports vpmovzxwd ymm0, xmm0... yes

  Solutions that I tried :

  I made sure I have a working GCC

  I have the update to date version of clang

  I have the update to date version of LLVM

• Looping Variables in a Batch File (for use with FFmpeg)

  16 avril 2021, par OrdinaryCarrot16

  I am creating a batch script that stores the input of the user into variables, that will later be used for creating converting files then adding metadata (via FFmpeg). It is working pretty good, now I'm just trying to figure out how to loop the FFmpeg line that uses all the variables the user inputted, and it will loop the command till it reaches the number specified in the 'track_amount' variable.

  


  Do you have any ideas on how to make this work ? Thanks !

  


  setlocal enabledelayedexpansion

:: Scan current directory for audio files
DIR *.mp3 OR *.m4a

set /P cover-art=Select the Audio/Image File with the Cover Art (ex. MP3/M4A or JPG/PNG): 
set /P artist=Artist/Band Name: 
set /P track_amount=How many tracks are in this album: 

if %track_amount% GTR 1 (
    set /P album=Album Name: 
)

set /P filename=Song File Name: 
set /P title=Song Name: 
set /P track=Track Number: 
set /P genre=Genre: 
set /P language=Language: 

ffmpeg -i "%cover-art%" -vf scale=512:512 -sws_flags bicubic cover_tmp.png

• FFmpeg problems with playing a stream

  13 avril 2021, par Niko

  I want to play a stream over network. While my server works I can't get it working receiving audio on client. It's router with openwrt installed and usb soundcard.

  


  When i run
ffmpeg -i "udp://@:5555" -f alsa hw:0 i get a following error

  


  [NULL @ 0x76b2b390] Requested output format 'alsa' is not a suitable output format
hw:0: Invalid argument


  


  What's wrong with my command ?
On router there is limited space. I hardly handled to install ffmpeg.

  


  There is complete log :
