• Python yt-dlp and ffmpeg error "merging of multiple formats but ffmpeg is not installed"

  27 mai, par T Tea Tie

  I am using the latest version of yt-dlp with Python 3.9.

  


  I am trying to download a youtube video in mp4 format with outputname as the youtubeid.mp4 and with best resolution not more than 4K.

  


  This is my Python code :

  


  ytid = '4cDqaLxrt6Q'
url = 'https://www.youtube.com/watch?v='+ytid
output_filename = ytid+".mp4"
    
with YoutubeDL({'format': 'bestvideo[height<=?4K]+bestaudio/best', 'output': output_filename}) as ydl:
    ydl.download(url)`#TODO debug FFmpeg and check if outputname is ok


  


  I expected to have an .mp4 file in my current working directory.

  


  Then I installed the latest version of FFmpeg from ffmpeg-master-latest-win64-gpl.zip and put ffmpeg.exe, ffplay.exe and ffprobe.exe in Scripts python folder (where yt-dlp.exe is). I also installed ffmpeg using pip install.

  


  The Traceback is :

• FFMPEG Kit issue in Banuba Video SDK : "FFmpegKit failed to start on brand"

  10 mai 2023, par Vivek Makwana

  I am trying to integrate Banuba Video Editor sdk in flutter.

  


  The issue i am facing is as below

  


  Banuba sdk works with native code for Android in Flutter

  


  So Banuba requires FFMPEG dependency to define in Native Android

  


  And I am already using 'ffmpeg_kit_flutter' plugin for flutter.

  


  So both the FFMPEG kits are conflicted and some of the functions are not found. due to that I am receiving the below error.

  


  When the app is launched I am receiving this Crash as mentioned

  


  **java.lang.Error: FFmpegKit failed to start on brand: google, model: sdk_gphone_x86, device: generic_x86_arm, api level: 30, abis: x86 armeabi-v7a armeabi, 32bit abis: x86 armeabi-v7a armeabi, 64bit abis: .&#xA;**  at com.arthenica.ffmpegkit.NativeLoader.loadLibrary(NativeLoader.java:50)&#xA;    at com.arthenica.ffmpegkit.NativeLoader.loadFFmpegKit(NativeLoader.java:189)&#xA;    at com.arthenica.ffmpegkit.FFmpegKitConfig.<clinit>(FFmpegKitConfig.java:145)&#xA;    at com.arthenica.ffmpegkit.FFmpegKitConfig.enableFFmpegSessionCompleteCallback(FFmpegKitConfig.java:864)&#xA;    at com.arthenica.ffmpegkit.flutter.FFmpegKitFlutterPlugin.registerGlobalCallbacks(FFmpegKitFlutterPlugin.java:168)&#xA;    at com.arthenica.ffmpegkit.flutter.FFmpegKitFlutterPlugin.init(FFmpegKitFlutterPlugin.java:652)&#xA;    at com.arthenica.ffmpegkit.flutter.FFmpegKitFlutterPlugin.onAttachedToActivity(FFmpegKitFlutterPlugin.java:198)&#xA;    at io.flutter.embedding.engine.FlutterEngineConnectionRegistry.attachToActivityInternal(FlutterEngineConnectionRegistry.java:351)&#xA;    at io.flutter.embedding.engine.FlutterEngineConnectionRegistry.attachToActivity(FlutterEngineConnectionRegistry.java:324)&#xA;    at io.flutter.embedding.android.FlutterActivityAndFragmentDelegate.onAttach(FlutterActivityAndFragmentDelegate.java:194)&#xA;    at io.flutter.embedding.android.FlutterActivity.onCreate(FlutterActivity.java:498)&#xA;    at com.sound.it.MainActivity.onCreate(MainActivity.kt:43)&#xA;    at android.app.Activity.performCreate(Activity.java:8000)&#xA;    at android.app.Activity.performCreate(Activity.java:7984)&#xA;    at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1309)&#xA;    at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:3422)&#xA;    at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3601)&#xA;    at android.app.servertransaction.LaunchActivityItem.execute(LaunchActivityItem.java:85)&#xA;    at android.app.servertransaction.TransactionExecutor.executeCallbacks(TransactionExecutor.java:135)&#xA;    at android.app.servertransaction.TransactionExecutor.execute(TransactionExecutor.java:95)&#xA;    at android.app.ActivityThread$H.handleMessage(ActivityThread.java:2066)&#xA;    at android.os.Handler.dispatchMessage(Handler.java:106)&#xA;    at android.os.Looper.loop(Looper.java:223)&#xA;    at android.app.ActivityThread.main(ActivityThread.java:7656)&#xA;    at java.lang.reflect.Method.invoke(Native Method)&#xA;    at com.android.internal.os.RuntimeInit$MethodAndArgsCaller.run(RuntimeInit.java:592)&#xA;    at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:947)&#xA;**Caused by: java.lang.UnsatisfiedLinkError: dlopen failed: cannot locate symbol "av_log_default_callback" referenced by "/data/app/~~umF3qlB9U53L4peU9nKYuQ==/com.sound.it-agqiFlNmMe17AHMK5gYIHw==/lib/x86/libffmpegkit.so"...**&#xA;    at java.lang.Runtime.loadLibrary0(Runtime.java:1087)&#xA;    at java.lang.Runtime.loadLibrary0(Runtime.java:1008)&#xA;    at java.lang.System.loadLibrary(System.java:1664)&#xA;    at com.arthenica.ffmpegkit.NativeLoader.loadLibrary(NativeLoader.java:48)&#xA;</clinit>

• ffmpeg "Error reinitializing filters !" on some webm videos

  9 février 2023, par The Blind Hawk

  I have a dozen of webm videos I need to resize with the following :

  


  ffmpeg -i input.webm -vf “scale=w=360:h=270:force_original_aspect_ratio=2,fps=10,crop=360:270” output.webm


  


  I tried the command and it worked fine for some webm videos, but most of the returned the following error :

  


  [AVFilterGraph @ 0x7fcb3db076c0] No such filter: '“scale'
Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
Error while processing the decoded data for stream #0:0
[libopus @ 0x7fcb3c10a000] 1 frames left in the queue on closing
Conversion failed!


  


  I checked that ffmpeg still worked fine with previously successful files.
  
How can I get ffmpeg to work with the remaining wemb videos ?
