FFMPEG Kit issue in Banuba Video SDK : "FFmpegKit failed to start on brand"
10 mai 2023, par Vivek MakwanaI 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: .

ffmpeg "Error reinitializing filters !" on some webm videos
9 février 2023, par The Blind HawkI 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 ?

error building ffmpeg on mac high sierra 10.13 "workspace/bin/ffmpeg' : No such file or directory"
14 mars 2023, par MartinHello I am trying to create a shell script
buildffmpeg.shwhich when ran, will download and build ffmpeg, so you can automate the process of making a custom ffmpeg build where the end result is an ffmpeg and ffprobe executable.

If you run the below script on mac or linux, it's worked perfectly, but when I test on my older macos 10.13 version, I first got an error about my ffmpeg snapshot url being too old :

FFMPEG_URL="https://git.ffmpeg.org/gitweb/ffmpeg.git/snapshot/74c4c539538e36d8df02de2484b045010d292f2c.tar.gz"
so I updated the var so it 'should' link to ffmpeg 6.0 (the most recent version, but im not sure if my link is correct)
FFMPEG_URL="https://git.ffmpeg.org/gitweb/ffmpeg.git/snapshot/adb4688bfb0652b2ffa5bc29e53761e27e1a3b3e.tar.gz"

When I run my below script on my mac terminal with the command
$ ./buildffmpeg.shit prints out '11' and then fails with an error :

...
INSTALL libavutil/ffversion.h
INSTALL libavutil/libavutil.pc
~11~
/Library/Developer/CommandLineTools/usr/bin/objdump: '/Users/apple/Documents/projects/buildffmpeghighsierra/workspace/bin/ffmpeg': No such file or directory


With the error being
workspace/bin/ffmpeg': No such file or directory

Is there something wrong with how my script builds ffmpeg ?
