• Glitchy mp4 File saved with Matplotlib Animation via ffmpeg

  9 janvier 2024, par Jacob Ivanov

  I am attempting to save an .mp4 file using matplotlib.animation to output some simulation results. The relevent section is as follows :

  


  ANI = FuncAnimation(fig, update, init_func = lambda : None, frames = range(0, 21300, 50))
ANI.save("[removed]/anim/v6 256 unforced 0.02.mp4", dpi = 600, fps = 30, writer = 'ffmpeg')


  


  However, it appears that there is some issue in the produced .mp4 file, as when I use macOS Quicktime to view the file, it pauses on certain frames, and restarts later on. It appears to consistently pause on the same frame a few seconds in. In order to check if Quicktime was the problem, I opened some random .mp4 files I found in a family group chat, and did not have this issue.

  


  I also tried viewing this .mp4 file with VLC, which had no issue, and played without any glitches. The Slack media viewer built into the app pauses similar to Quicktime.

  


  The following are all relevant versions :

  


  

  • macOS : 14.2.1 (23C71)

  


  • Python : 3.10.9 via Homebrew

  


  • Matplotlib : 3.6.2

  


  • ffmpeg : 6.1.1

  


  


  If it would help, I can also provide the .mp4 file itself, but I'm not quite sure how to upload it. I will be happy to provide any additional information as well.

  


  Unfortunately, I'm not very familiar with video rendering, but I would appreciate any help anyone could provide. Thank you in advance !

  


• How do i gain access to subproccess.py ?

  15 décembre 2023, par Kronik71

  So, my bot for some reason wants to access a folder in \WindowsApps\PythonSoftwareFoundation.Python.bunch_of_numbers\Lib called subproccess.py but it always gives the error : PermissionError: [WinError 5] Access is denied. I think it has to do with ffmpeg.

  


  Here's the full traceback (kinda long) :

  heres my code :

  


  import interactions

from discord import FFmpegPCMAudio
import tracemalloc

ffmpegexec = r"C:\Users\myuser\OneDrive\Desktop\ffmpeg-6.1-essentials_build\bin\ffmpeg.exe"

audiosource = r"C:\Users\myuser\Downloads\seatbelt-online-audio-converter.mp3"

source = discord.FFmpegPCMAudio(audiosource)

token = "my_token"

bot = interactions.Client(token=token)

tracemalloc.start()

@interactions.slash_command(
    name="joinvc",
    description="starts the game"
)

async def joinvc(ctx: interactions.ComponentContext):
    await ctx.send("Joining vc. Please make sure you are currently in a vc!")
    vc = ctx.author.voice.channel
    await vc.connect()

@interactions.slash_command(
    name="press",
    description="Press the button"
)

async def press(ctx: interactions.ComponentContext):
    await ctx.send(f"{ctx.author.mention} has pressed the button")
    vc = ctx.author.voice.channel
    voice_client = await vc.connect()  # Connect to the voice channel

voice_client.play(discord.FFmpegPCMAudio(executable=r"C:\Users\myuser\OneDrive\Desktop\ffmpeg-6.1-essentials_build\bin", source=audiosource))


bot.start(token)


  


  All of my code is above. I'm not exactly good at writing python, might just be something I'm misunderstanding. I just want it to play a noise in a discord voice chat when the /press command is used.

  


• Cannot Compile FFMPEG with libfreetype on Windows/Msys2

  10 octobre 2024, par Devin Dixon

  I am having issues compiling ffmpeg with libfreetype with this commmand on windows MSYS2 :

  


  ./configure     --pkg-config-flags="--static" --enable-libvpl  --enable-libopenh264     --enable-version3  --enable-libfreetype    --enable-libopus     --enable-libvpx     --enable-libvorbis     --enable-libaom     --enable-libdav1d     --disable-gpl     --disable-w32threads     --enable-pthreads     --disable-shared     --enable-static     --extra-cflags='--static'   --extra-cflags="-I/mingw64/include -static"   --extra-ldflags="-L/mingw64/lib -static" --prefix="/home/compiled"


  


  I keep getting this error :

  


  ERROR: freetype2 not found using pkg-config

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.


  


  I've installed freetype with this command :

  


   pacman -Ss mingw-w64-x86_64-freetype


  


  I've also tried compiling freetype2 from the source :

  


  git clone https://git.savannah.gnu.org/git/freetype/freetype2.git

cd freetype2

mkdir build && cd build

/mingw64/bin/cmake .. -G "MSYS Makefiles" -DBUILD_SHARED_LIBS=OFF -DCMAKE_INSTALL_PREFIX=/mingw64

make

make install


  


  And pkg-config gives this :

  


  pkg-config freetype2 --cflags --libs
-IC:/msys64/mingw64/include/freetype2 -IC:/msys64/mingw64/include/harfbuzz -IC:/msys64/mingw64/include/glib-2.0 -IC:/msys64/mingw64/lib/glib-2.0/include -IC:/msys64/mingw64/include/libpng16 -lfreetype


  


  I can confirm the package is there :

  


  ls /mingw64/lib/pkgconfig/freetype2.pc
/mingw64/lib/pkgconfig/freetype2.pc


  


  Is there anything else I should be doing to compile a static version of ffmpeg with this package ?
