• avformat/dump : lowercase 'Start' prefix for start offset

  avformat/dump : lowercase 'Start' prefix for start offset
  Just applying some UX polish.
  
  This is to match the lowercase trend of attributes in
  
  the dump string (and similar to chapters).

  • [DH] libavformat/dump.c

• FFmpeg Arthenica always encodes with x265 Main10 profile [closed]

  5 avril, par Jabed Dhali

  I'm using FFmpeg-Kit (Arthenica) for iOS to compress videos using the libx265 encoder. I'm building FFmpeg with a custom configuration script :

  


  export CUSTOM_CONFIG="--disable-indevs \
  --disable-outdevs \
  --disable-hwaccels \
  --enable-videotoolbox \
  --disable-protocols \
  --enable-protocol=file,fd,saf,async \
  --disable-decoders \
  --enable-decoder=${ENABLE_DECODER_LIST} \
  --disable-encoders \
  --enable-encoder=${ENABLE_ENCODER_LIST}"

export CUSTOM_CONFIG_IOS=${CUSTOM_CONFIG}
  ./ios.sh --enable-ios-videotoolbox --enable-lame --enable-libaom  --enable-libtheora --enable-libvorbis --enable-libvpx --enable-libwebp --enable-libxml2 --enable-opencore-amr --enable-openh264 --enable-opus --enable-twolame --enable-x264 --enable-x265 --enable-gpl


  


  Then I run FFmpeg with the following commands :

  


  -y -hide_banner -i input.MOV -vcodec libx265 -x265-params profile=main output.mov
-y -hide_banner -i input.MOV -vcodec libx265 -x265-params profile=main10 output.mov


  


  However, regardless of the profile I set, the output always ends up being encoded with the Main10 profile.

  


  Here’s the log output :

  


  x265 [info]: HEVC encoder version 3.4
x265 [info]: build info [Mac OS X][clang 16.0.0][32 bit][noasm] 10bit
x265 [info]: using cpu capabilities: none!
x265 [info]: Main 10 profile, Level-5 (Main tier)


  


  It seems that the FFmpeg build only supports 10-bit encoding. I want to be able to encode with different profiles (main, main10, etc.), as well as to build libx265 in a way that supports 8-bit + 10-bit + 12-bit encoding (unified 64-bit build), as like as the same command executes for MacOS.

  


  x265 [info]: HEVC encoder version 4.1+1-1d117be
x265 [info]: build info [Mac OS X][clang 16.0.0][64 bit] 8bit+10bit+12bit
x265 [info]: using cpu capabilities: NEON Neon_DotProd Neon_I8MM
x265 [info]: Main profile, Level-2.1 (Main tier)


  


  How can I correctly configure and build FFmpeg and libx265 with Mobile FFmpeg to support multiple bit depths and allow setting different profiles via -x265-params ?

  


• Cant add a custom name to my fluent-ffmpeg converted file

  11 août 2019, par mouchin777

  Im trying to add a custom name based on the name of the downloaded youtube video to the file converted by fluent-ffmpeg. Problem is I dont know how to add it into the function since var saveLocation isnt being overwriten.

      const ytdl = require('ytdl-core')
  
  const  ffmpeg = require('fluent-ffmpeg');
  
  ffmpeg.setFfmpegPath("myffmpegLocation.exe")
  
  
  
  videoUrl = "this_is_a_youtube_url"
  
  var saveLocation = "";
  
  
  
  stream = ytdl(videoUrl).on('info', (info) => {
  
      console.log(info.title)
  
      saveLocation = "./"+info.title+".mp3" //this is not being saved
  
    });
  
  
  
  
  
  var proc = new ffmpeg({ source: stream, nolog: true }).toFormat('mp3').audioBitrate(320).on('end', function() {
  
      console.log('file has been converted successfully');
  
      })
  
      .on('error', function(err) {
  
      console.log('an error happened: ' + err.message);
  
      })
  
      .saveToFile(saveLocation); //The file title --> I want to use the var saveLocation there
