• Adding x264 and AAC encoding to a Telegram-based FFmpeg script

  1er octobre 2024, par Pooria Darvishi

  I'm trying to modify a Telegram script that utilizes static FFmpeg and VPX libraries to also include x264 and AAC encoding. I'm quite new to this and could use some guidance.

  


  Background :

  


  Telegram uses static .a files of FFmpeg and VPX, compiled using NDK. I have the script that builds these libraries. I want to modify this script to include x264 and AAC libraries as well.

  


  Problem :

  


  I'm unsure how to integrate x264 and AAC into the existing build process and how to configure FFmpeg to use these codecs.

  


  Code snippets :

  


  build_ffmpeg.sh :

  


  #!/bin/bash

# instructions for build
# used
# ffmpeg 4.4.3
# lib vpx 1.10.9
# NDK for compile libvpx. Last successful build with 21.1.6352462
# NDK r10e for compile ffmpeg
#
# 1) download ffmpeg
# 2) set NDK_r10e and NDK variables
# 3) download lib vpx
# 4) copy libvpx to vpx-android folder and rename as libvpx
# 5) copy build_ffmpeg foleder in ffmepg directory
# 6) run build_ffmpeg.sh
# 7) see compiled library in build_ffmpeg/adnroid folder

  Any help would be greatly appreciated.

  


  I'm working on an Android app that requires custom video encoding using FFmpeg. I've tried to build a newer version of FFmpeg but couldn't integrate it into my project due to the older version requirement. I've also tried pre-built scripts that support a wide range of codecs, but they don't generate the necessary .a files for libraries like x264, VPX, and AAC.

  


• Mapping streams by language in FFmpeg

  8 décembre 2016, par ffmpeg123

  I have lots of files with multiple audio and subtitle languages, however the track numbers aren’t consistent (the English audio stream isn’t always the first) so using a command such as :

  ffmpeg -i "input.mkv" -map 0 -map -0:a:1 -c:v copy -c:a copy "output.mkv"

  doesn’t yield expected results. After searching around I discovered it was possible to map streams based on language with this command :

  ffmpeg -i "input.mkv" -map 0 -map -0:m:language:eng -c:v copy -c:a copy "output.mkv"

  However -map -0:m:language:eng will remove all tracks with the English language flag. To keep the subtitle tracks you can use -map 0:s this is a good solution however, I want to know if it’s possible to only map audio streams based on language.
