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 : "Input/output error" Read gif from named pipe ?
23 octobre 2022, par XiradoI've been trying to debug this for hours now, and cannot seem to understand why it doesn't work.


I want to overlay a png onto all frames of a gif, and since writing all the files to disk is slow, i wanted to use pipes.


I created a named pipe using
mkfifo imgstream1and then launch ffmpeg :

ffmpeg -report -hide_banner -v 9 -loglevel 99 -y -f gif -i imgstream1 out1.gif


(This isn't actually useful as it just spits out the same gif again but it's simpler for debugging)


After ffmpeg launches it waits for data from the pipe, so i write an actual gif file to the pipe using this kotlin code


val backgroundFifo = File("imgstream1")
val inputOne = File("background.gif").readBytes()
println("background.gif -> ${inputOne.size} bytes")
val output = backgroundFifo.outputStream()
output.write(inputOne)
output.flush()
output.close()


It prints :
background.gif -> 7233247 bytes

Now ffmpeg should read the bytes and spit out a gif, but it always seems to fail doing so.


Opening an input file: imgstream1.
[gif @ 0x7714180] Opening 'imgstream1' for reading
[file @ 0x7714980] Setting default whitelist 'file,crypto,data'
[AVIOContext @ 0x7724dc0] Statistics: 7233247 bytes read, 0 seeks
imgstream1: Input/output error


Sadly this does not give any further information, i'm already on the highest log level...


I've tried multiple things :


- 

-f image2pipe-> Works, but only loads the first 2 frames of the gif- Renaming the pipe to
imgstream1.gifso ffmpeg thinks it's a gif file, no change. - Different ffmpeg versions
- Using the actual gif as an ffmpeg input works










At this point i have no idea what the problem might be, as ffmpeg seems to load all bytes.
It's worth noting that doing
cat imgstream1 > file.gifproduces the desired gif.

Any help would be appreciated !

ffmpeg Windows : standard transcode produces file that "uses unsupported encoding settings" [duplicate]
17 août 2022, par David M. Cotterusing the basic command :


ffmpeg -i infile.mp4 -vcodec libx264 -acodec aac output.mp4


poduces a file that can't be played by the standard Windows Media Player app.
Is there something i'm missing ?


Here is the log data.
