• Build FFmpeg with Freetype2 for ARM ( Android )

  14 mai 2014, par Pawel Cala

  I’m trying to build FFmpeg binary file with freetype library included ( I need it for drawtext filter ). Unfortunately I cannot configure ffmpeg properly and every try ends with "freetype not found" error.

  PS I’ve tried to build guardian-ffmpeg project but i’m getting errors during configure process.

  PS2 Building plain ffmpeg works perfectly well

  Configuration script :

  make distclean &./configure --target-os=linux \
  
  --cross-prefix=arm-linux-androideabi- \
  
  --arch=arm \
  
  --cpu=armv7-a \
  
  --enable-libfreetype --enable-filter=drawtext \ #!Freetype params
  
  --disable-network \
  
  --disable-ffplay \
  
  --disable-ffprobe \
  
  --disable-ffserver \
  
  --enable-protocol=file \
  
  --sysroot=${ANDROID_NDK_ROOT_PATH}/platforms/${ANDROID_API_VERSION}/arch-arm \
  
  --prefix=build/armeabi-v7a \
  
  --disable-asm \
  
  --extra-cflags='-DANDROID -Ifreetype2/ -I${ANDROID_NDK_ROOT_PATH}/sources/cxx-stl/system/include -march=armv7-a -mfloat-abi=softfp' \
  
  --extra-ldflags='-Wl,--fix-cortex-a8 -Lfreetype2/ -L../android-libs -Wl,-rpath-link,../android-libs' \
  
  --extra-cxxflags='-Wno-multichar -fno-exceptions -fno-rtti'
  
  make -j6 && make install || exit 0

  Directories sctructure :

  ffmpeg/
  
     -ffmpeg dirs/
  
     -freetype2/
  
     -rest of ffmpeg files ( including configure, make, etc )

  I’ve checked patch sources in guardian-project and I’ve found that ffmpeg configure file might need some changes in require_libfreetype method ?!

  Thanks in advance ( and sorry for my bad english )

  EDIT :
  Building on OSX Mavericks,
  Last 3 lines of config.log ; OSX hasn’t got pkg-config therefore false in 2nd line :

  require_libfreetype
  
  false --exists --print-errors freetype
  
  ERROR: freetype not found

  With sessions in English, French, German, and beyond, MatomoCamp aims to make digital analytics more accessible, ethical, and transparent for everyone.

  MatomoCamp returns this November 2025 with an exciting new vision. For the first time, we’re expanding beyond purely technical content to welcome speakers from all backgrounds who can contribute insights on analytics, privacy, marketing, and the ethical web. Whether you’re a developer, marketer, analyst, or privacy advocate, we want to hear from you.

  What makes a great talk ?

  There’s no one right formula. But here’s what works well :

  • Real-world experience
  • Specific, actionable insights
  • A clear structure (15–45 minutes)
  • Something you care deeply about
  • A story only you can tell

  And remember — this isn’t just about Matomo. Topics that touch on ethical analytics, open source values, or digital sovereignty are more than welcome.

  Why does this matter ?

  At Matomo, we believe that data should empower, not exploit. MatomoCamp is more than just an event — it’s a celebration of what’s possible when communities come together to build a better digital future.

  As sponsors, we’re proud to support this independent, open source event. But more importantly, we want to amplify your voice — because every perspective shared brings us closer to a more ethical, transparent, and inclusive analytics ecosystem.

• ffmpeg transcode to hls and multiple aac audio tracks

  23 août 2023, par Aquarius

  I'm trying to transcode h264 mp4 file to HLS format with multiple AAC audio tracks. On Windows browsers everythins works like a shine. There's an option to switch audio track

  


  

  


  It doesn't work on Android devices or TV. On Android Opera browser video works with sound, but screen stuck while seeking and there's no option to switch audio track. On TV browser video works, it doesn't stuck when seeking but also no option to switch audio track

  


  Using video.js player on site. Below code for transcode and produced manifest file

  


  ffmpeg -i "file.mp4" -i PL-6ch.aac -i EN-6ch.aac -map 0:v -map 1:a -map 2:a -c:v copy -c:a:0 aac -ac:a:0 6 -af channelmap=channel_layout=5.1 -c:a:1 aac -ac:a:1 6 -af channelmap=channel_layout=5.1 -tag:v:0 h264 -b:v:0 2500k -tag:a:0 aac -b:a:0 384k -tag:a:1 aac -b:a:1 384k -f hls -hls_time 10 -hls_playlist_type vod -hls_list_size 0 -master_pl_name file.m3u8 -var_stream_map "v:0,agroup:AAC a:0,agroup:AAC,language:pl a:1,agroup:AAC,language:en" file_%v_.m3u8
