QUESTION
I'm trying to build a small project that uses ffmpeg library to WebAssembly, with use of Emscripten. Before that, I tried it out by transpiling some simple program from C into Wasm and it worked fine, but that time I was not using any additional libraries.
For C++ I'm working with Visual Studio and FFmpeg I linked in project's "Properties" as follows:
all .h header files I placed in "include" catalog and I added it as "Additional Include Directories" in "C/C++" section
all .lib and .dll.a (for example avcodec.lib or libavcodec.dll.a) files I placed in "lib" and added as "Additional Library Directories" in "Linker" section
All includes and the program itself works fine, so now I was trying to prepare a Wasm module with Emscripten with the same same command that I used earlier, but already knowing that is not going to work:
...ANSWER
Answered 2021-Apr-13 at 12:56Build the FFmpeg libs with Emscripten is not an easy task, but you can follow the ffmpeg.wasm tutorials:
Read carefully until the end all the tutorial, because there are so many issues that can arise.
NoteI suggest to you to start with the FFmpeg and Emscripten version used in the tutorial and look at the build-ffmpeg.sh script. The script itself export a wasm file with a main function

I encountered this error when upgraded react-native version to 0.63.0. I searched this error but according to other sources it is either problem in react-native-material-dropdown or in react-native-material-textfield. I have also tried to look for Animated.Text.propTypes in node_modules but it does not exist. Although i found it in main.bundle.js in ios folder. My Pod file is as following:

QUESTION
I am using this FFMPEG library,
first I am playing the video inside my videoView to make sure that the video path is correct
...ANSWER
Answered 2020-Jun-22 at 18:57Alright After some digging around it turns out that I was supposed to give a path and a name to the FFmpeg to create the file for me and save the data inside that file, I shouldn't create the file and give it the file path because FFmpeg will try to overwrite that file with the one it is trying to create, by default FFmpeg doesn't have permission to overwrite it,lastly, you should also add the file extension (I was saving the file without the extension)
So what is the solution? you can simply give a path to where you want to the FFmpeg to create the file but without creating the file yourself like so
QUESTION
I discovered that Windows Photo has a pretty good basic video editor hidden in it.
My wife used it to edit a family video. Then she wanted to save the project (clips and project file, not just the final product) to USB drive.
Photo only gives you one option: Save to OneDrive. The claim is that other OneDrive devices running Photo will then be able to see the Project.
However, careful inspection of OneDrive yields no file with the title of the project and nothing that obviously looks like a video editing project file.
Does anybody know how they pulled this off and where they have hidden the project information? It can't be buried in the Registry, because that wouldn't transfer through OneDrive.
...ANSWER
Answered 2019-Apr-22 at 06:15There were two reasons I was looking into this.
1) For a video project, set the duration for all the photos in a storyboard to something other than the default. (Why isn't this built in?) and;
2) On another project, reset the duration that I'd set on a bunch of photos so it could auto sync with music.
So, I looked into this a bit, and for reference the data is stored in an Sqlite database called MediaDb.v1.sqlite located by default here (replace YOURUSERNAME) C:\Users\YOURUSERNAME\AppData\Local\Packages\Microsoft.Windows.Photos_8wekyb3d8bbwe\LocalState
You can load the database using an Sqlite reader like DB Browser however you can't update it because it contains an unrecognised database collation (column character set) called NoCaseUnicode which you can about more here
There are others who are reporting similar problems trying to access this file.
QUESTION
I'm tring to read list of videos from file and show them in ionic components in the form of list with thumbnail of the video file.But thumbnail is not created for each file properly.
videos.ts
...ANSWER
Answered 2018-Oct-06 at 06:34" Thumbnail for only fist file is created " because you used
Reason-
createThumbnail() -
it take some time to create thumbnail of video but in other side html done its work fast so html pass first url to this function and then this function is busy to make thumbnail of it,but html send all the url to this function but it is still busy so its only create one thumbnail.
Solution -
you must have to make **async** and **await** task or function so that html wait for createThumbnail().so every time html send url to this function then html wait for that function task and then send next url to that function.
here's my code for create thumbnails
async favourite(fileName){
let thumbName = fileName.substr(fileName.lastIndexOf('/') + 1);
const result = await this.commonserviceProvider.thumbUpload(thumbName,fileName); //this service is called for create thumbanils and favourite() function wait for this service
let videoName = fileName.match(/([^\/]+)(?=\.\w+$)/)[0];
const result1 = await this.commonserviceProvider.upload(videoName+".mp4",this.folderPath+videoName+".mp4",1);
this.presentToast('Saved in favourite');
}

I got this error when trying ionic cordova build android --prod --release, using ionic serve or ionic cordova run android the app works good.
Error: Type PdfViewerComponent in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts is part of the declarations of 2 modules: PdfViewerModule in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts and PdfModalPageModule in C:/app/src/pages/document-pdf/document-pdf.module.ts! Please consider moving PdfViewerComponent in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts to a higher module that imports PdfViewerModule in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts and PdfModalPageModule in C:/app/src/pages/document-pdf/document-pdf.module.ts. You can also create a new NgModule that exports and includes PdfViewerComponent in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts then import that NgModule in PdfViewerModule in C:/app/node_modules/ng2-pdf-viewer/ng2-pdf-viewer.d.ts and PdfModalPageModule in C:/app/src/pages/document-pdf/document-pdf.module.ts.
I only import ng-pdf-viewer in document-pdf.module.ts not in app.module.ts
ANSWER
Answered 2018-Feb-11 at 21:25You should import the PdfViewerModule in your document-pdf.module.ts, and do not declare the PdfViewerComponent in there, as it is already declared in the PdfViewerModule.
Update: this is how your module should look like:

My ffmpeg for my ANDROID APPLICATION on android studio 2.3.3 is compiled using this:
compile 'com.writingminds:FFmpegAndroid:0.3.2'
In the code below i have this line of code:
String[] complexCommand = {"-i", yourRealPath, "-c:v", "libx264", "-crf", "22", "-map", "0", "-segment_time", "6", "-g", "9", "-sc_threshold", "0", "-force_key_frames", "expr:gte(t,n_forced*6)", "-f", "segment", dest.getAbsolutePath()};
What i want to know:
- How do i change that complex command that i have such that i can get the last 15 frames of a 2 seconds-long 30fps video.
This is the code I'm referencing:

Answered 2017-Jul-20 at 09:53Use the select filter to select specific frames by their index.
2 seconds of video at 30 fps have 60 frames, so you want all frames from 45 onwards:

Things i want to know:
- I'd like to know what those inputs(i.e. "-sc_threshold", "-g", "-crf") are, and what are their functions.
- If a video has 30fps and is 5 seconds long, are there 150 frames, if so is ffmpeg able to extact all 150?
This is my code:
...ANSWER
Answered 2017-Jul-19 at 05:481.
-sc_threshold : It is the scene change sensitvity (range between 0 - 100). At every scene change , a new I-frame is inserted.
-g : It is GOP(Group of Pictures).Frame length interval. GOP determines maximum distance between I-frames. Bonus tips : High GOP makes video very effecient compression. Recommended value is 250
-crf : Constant Rate Factor(CRF) defines a average desired quality instead of target bitrate.
2.
Yes , It is possible to fetch each frames recorded so far in video container using FFMPEG libs.
Bonus : ffmpeg -i video.avi IMG%03d.jpg - sample command to fetch each frame and convert that as a jpg image file and store it in same location.
