• compiling ffmpeg for Mac OSX High Sierra 10.13

  29 juillet 2021, par Martin

  Hello I made an electron app that uses ffmpeg to combine audio and renders video, it works fine on windows, linux, and modern mac osx computers, but a user has reported to me that on an older version of mac osx such as High Sierra 10.13, the way that I have setup ffmpeg does not work.

  


  I have a virtual machine with High Sierra v10.13 where I install RenderTune-mac.dmg from my RenderTune releases page, then I download 2 audio files and the image from this link. I open RenderTune, and try render a video. My command to combine the audio files into a single mp3 works fine, but when I try to combine that mp3 with the image file, the ffmpeg build I have packaged with my electron app fails with this error :

  


  Command was killed with SIGABRT (Aborted): /Applications/RenderTune.app/Contents/Resources/ffmpeg -loop 1 -framerate 2 -i /Users/martin/Downloads/R-3777978-1344032418-8379.jpeg.jpg -i /Users/martin/Downloads/output-871140.mp3 -y -acodec copy -b:a 320k -vcodec libx264 -b:v 8000k -maxrate 8000k -minrate 8000k -bufsize 3M -filter:v scale=w=1920:h=1954 -preset medium -tune stillimage -crf 18 -pix_fmt yuv420p -shortest /Users/martin/Downloads/concatVideo-871140.mp4

  These files will render fine on windows/linux and recent mac versions. In order to package ffmpeg in my electron app on mac computers I had to build a custom sandboxed version with no dynamically linked libraries. I have a .sh file that automatically downloads ffmpeg and builds it with all the necessary flags for mac computers.
https://github.com/MartinBarker/RenderTune/blob/master/buildffmpeg.sh
Inside this .sh file is where I compile ffmpeg using these flags :

  


  ./configure \
    --pkgconfigdir="$WORKSPACE/lib/pkgconfig" \
    --prefix=${WORKSPACE} \
    --pkg-config-flags="--static" \
    --extra-cflags="-I$WORKSPACE/include -mmacosx-version-min=${MACOS_MIN}" \
    --extra-ldflags="-L$WORKSPACE/lib -mmacosx-version-min=${MACOS_MIN}" \
    --extra-libs="-lpthread -lm" \
        --enable-static \
        --disable-securetransport \
        --disable-debug \
        --disable-shared \
        --disable-ffplay \
        --disable-lzma \
        --disable-doc \
        --enable-version3 \
        --enable-pthreads \
        --enable-runtime-cpudetect \
        --enable-avfilter \
        --enable-filters \
        --disable-libxcb \
        --enable-gpl \
        --enable-nonfree \
        --disable-libass \
        --enable-libfdk-aac \
        --enable-libmp3lame \
        --enable-libx264 


  


  If I try to run this script in my High Sierra VM, it fails with this message :

  


  Unknown option "-extra-libs=-lpthread"

  


  if I remove that flag it fails with a different message :

  


  Unknown option "--enable-static"

  


  I need this flag in order to release my electron app on the mac apple store, can anyone help me compile a static version of ffmpeg that works on old versions like High Sierra 10.13 as well as works on modern mac os systems ?

  


• How to debug "Error in pull function & Input buffer exhausted" ?

  15 septembre 2021, par user16909319

  Introduction :

  


  I'm working on a Discord Music Bot for personal use only. Basically, when I play a 2min song with the bot, it plays the song for 1min 30secs, then skips it and plays the next one in the queue. The error is shown below :

  


  


  Error in Pull Function
  
IO error : Error number -10054 occurred
  
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] Packet corrupt (stream = 0, dts = 11154432).
  
Input buffer exhausted before END element found
  
Invalid Data found when processing Input
  
[mov,mp4,m4a,3gp,3g2,mj2 @ 0000018f86a6f4c0] stream 0, offset 0x3e805c : partial file

  


  


  The code block which I think is causing the problem :

  


  Search song method

  


      async def search_song(self, amount, song, get_url=False):
        info = await self.bot.loop.run_in_executor(None, lambda: youtube_dl.YoutubeDL(ytdl_format_options).extract_info(
            f"ytsearch{amount}:{song}", download=False, ie_key="YoutubeSearch"))
        if len(info["entries"]) == 0: return None

        return [entry["webpage_url"] for entry in info["entries"]] if get_url else info


  


  Play_song method

  


      async def play_song(self, ctx, song):
        url = pafy.new(song).getbestaudio().url
        ctx.voice_client.play(discord.PCMVolumeTransformer(discord.FFmpegPCMAudio(url, executable="C:/ffmpeg/bin/ffmpeg.exe")),
                              after=lambda error: self.bot.loop.create_task(self.check_queue(ctx)))
        ctx.voice_client.source.volume = 0.5


  


  Formatting Options I provided :

  


  ytdl_format_options = {
    'format': 'bestaudio/best',
    'outtmpl': '%(extractor)s-%(id)s-%(title)s.%(ext)s',
    'restrictfilenames': True,
    'noplaylist': True,
    'nocheckcertificate': True,
    'ignoreerrors': True,
    'logtostderr': False,
    'quiet': True,
    'no_warnings': True,
    'default_search': 'auto',
    'source_address': '0.0.0.0'
}


  


  Solutions that I've tried :

  


  

  • Running it on both Replit and locally.

  


  • Redownloading FFmpeg

  


  • Ensuring FFmpeg, pafy, and youtube_dl are all up to date.

  


  


  Things to Note :

  


  

  • Playing a 2mins song, it stops after 1min 30 seconds and displays the error above. (75% of the song)

  


  • Playing a 1hr song, it still continues after 10 minutes.

  


  


  I do not have much experience in this yet so I'm not entirely sure where in my code is actually causing this issue or other ways which I can use to test and fix the issue.
