mobile-ffmpeg | FFmpeg for Android, iOS and tvOS Not maintained anymore Superseded by FFmpegKit | Graphics library

I have a video cropper working fine to all videos I tested, but a video from s20 ultra, gives me some error in FFmpeg, i don't really know if the video is oversize or not my source code https://github.com/rushidevmurari/RushiCropVideo/blob/213166834b0bc6ce83ab3f4ac494f261a57d7436/app/src/main/java/com/androworld/allinonevideoeditor/videocrop/VideoCropActivity.java

I got these link but nothing good to my work Error when cropping video using FFMPEG

I am using libVLCSharp (Xamarin bindings to the libvlc library) for video playback. I am adding a feature to transcode / compress downloaded videos to the local filesystem. Normally I'd use mobile-ffmpeg for this, but since internally VLC uses ffmpeg with different build configurations, ffmpeg transcoding does not work - android it crashes the app, ios returns a 'Invalid data found when processing input' error message when attempting to convert. The code works fine when libvlcsharp is uninstalled and there is only one instance of the ffmpeg library being used.

So, I'm looking for video compression / transcode options for Xamarin.iOS.

I've looked into the docs for libvlcsharp and it sounds like we can transcode, but it's somewhat vague on how to do that:

https://github.com/videolan/libvlcsharp/blob/3.x/docs/how_do_I_do_X.md

How do I do transcoding? Pretty similarly to how you would do it from the CLI. Read https://wiki.videolan.org/Transcode/ and try media options with Media.AddOption.

In my case, I'd like to transcode non-interactively / in the background of the app. There is a 'dummy' option in the command line interface for doing this, so I was wondering how we'd do this from libvlc / libvlcsharp.

So far, my code from these docs looks like this:

Issue : I have 7 images in a list (with different size, resolution and format). I am adding an mp3 audio file and fade effect while making a slideshow with them, as i am trying to do it by following command

I am adding video stream capture functionality to a Xamarin Forms project. I am trying to use VLC's LibVLCSharp.Forms (https://github.com/videolan/libvlcsharp) package and the Mobile ffmpeg Xamarin wrapper package, Laerdal.Xamarin.FFmpeg.* (https://github.com/Laerdal/Laerdal.Xamarin.FFmpeg.iOS). However, the internal ffmpeg library from VLC is conflicting with the ffmpeg wrapper and is built with different flags which exclude functionality that I need.

For native development, it looks like you can configure a preferred library with the OTHER_LDFLAGS flag in the Pods-.debug.xcconfig file but I don't see where to do that with Xamarin.Forms. Source: https://github.com/tanersener/mobile-ffmpeg/wiki/Using-Multiple-FFmpeg-Implementations-In-The-Same-iOS-Application

How can I configure Xamarin iOS builds to prefer the mobile ffmpeg library over the VLC ffmpeg library? If I am able to use the mobile ffmpeg library, will it cause issues with VLC?

Here is a log message when I try to run commands with ffmpeg. As you can see, ffmpeg's internal library paths reference "vlc":

I tried to create a video using multiple images having different scales or sizes or (height*widths) using Mobile-FFmpeg #
I am using this code script to get the required result:

The only thing I want to do is convert wav files to mp3 inside my Android application.

I am currently using https://github.com/tanersener/mobile-ffmpeg and with audio-release everything is working fine. As the lib size is about 40 MB and I only need a single command, I'd like to build my own .aar file as described in the Wiki to reduce the application size.

I edited the android-ffmpeh.sh ./configure:

I try to create a video with ffmpeg and save it to the device with gallery_saver package for Flutter.

The ffmpeg command works well and the video is created. But GallerySaver does not save it. As result I get no error, but a false boolean for the success argument.

This is the ffmpeg output. Is this a valid video mp4 file?

I´m using ffmpeg with flutter and I create a video from a lot of images. The problem: ffmpeg seems to not create a video with a right codec or something else.... please check my description below for concrete informations.

First the code parts:

Creating video from images

-r $settings_fps -i $tempPath/img%04d.jpg -vcodec libx264 -y -an -vf "pad=ceil(iw/2)*2:ceil(ih/2)*2" -shortest $tempPath/$videoFileName.mp4

Adding audio to the created video

-i ${finalSong.path} -i $videoPath -c:a aac -shortest $tempPath/$newVideoFileName.mp4

This is my video output from console on creating this video:

I'm making a movie player with libav. I have decoding video packets working, I have play in reverse working, I have seeking working. All this works no an x86 android emulator, but fails to work on a real android phone (arm64-v8a)

The failure is in sws_scale() - it returns 0. The video frames continue to be decoded properly with no errors.

There are no errors, warnings, alerts from libav. I have connected an avlog_callback
