FFmpeg process finishes writing the file only after closing the program
20 juin 2024, par The EngineerMy JavaFX application uses FFmpeg to extract the first frame from a video file in a separate thread and the process ends with a wait. The image is saved to a temporary directory (temp/video_preview.jpg) but becomes available only after the forced termination of the entire program. I need the image for display in ImageView immediately after the FFmpeg process is completed.


@FXML
private void onDragOver(DragEvent event) {
 if (event.getDragboard().hasFiles()) {
 event.acceptTransferModes(TransferMode.ANY);
 }
}

@FXML
private void onDragDropped(DragEvent event) {
 Dragboard db = event.getDragboard();
 boolean success = false;
 if (db.hasFiles()) {
 List<file> files = db.getFiles();
 File videoFile = files.get(0);
 Image image = extractFirstFrameFromVideo(videoFile.getAbsolutePath());
 mainImage.setImage(image);
 success = true;
 }
 event.setDropCompleted(success);
 event.consume();
}
</file>

private Image extractFirstFrameFromVideo(String pathToVideo) {
 try {
 ProcessBuilder processBuilder = new ProcessBuilder(
 ffmpegPath,
 "-y",
 "-ss", "00:00:00",
 "-i", pathToVideo,
 "-frames:v", "1",
 outputFilePath // "temp/video_preview.jpg"
 );

 Process process = processBuilder.start();

 int exitCode = process.exitValue();
 if (exitCode != 0) {
 throw new IOException("ffmpeg process exited with error code: " + exitCode);
 }

 return new Image(new File(outputFilePath).toURI().toString());

 } catch (IOException e) {
 throw new RuntimeException(e);
 }
}

How to record a video conference (e.g skype, oovoo, ...) with a program written in C#
13 août 2014, par Matin LotfalieeI want to record screen (a video conference e.g skype, oovoo, ...) with a program written in C#. I searched a lot about how to do this :
- Here suggests Windows Media Encoder, but none of their samples work correctly on my Win7. I installed the SDK but even the links to Microsoft are somehow broken or old.
- Here suggests creating a video stream from a series of screenshots using ffmpeg. but it is probably impossible to keep the audio,mic and screenshots synced.
- Here suggests creating a GIF file, but it does not support audio which is important to me.
- Here suggess using Gallio framework, but I was unable to find where the usable DLL for recording is.
- Here seems to be a great solution but it is not free...
Compression is not important to me because a video conference uses CPU a lot.
Can you help me find a good and easy solution with references ?

Why does console output "illegal aspect ratio" when program reads a flv file？
11 décembre 2015, par xiaolanI use program to read a flv file. After it executed the avformat_find_stream_info() function, the console outputs some error information. Here is detailed error information.I want to know reasons. In fact, the file with flv format is made by myself. The producing process is : I encode a H.264 packet, then write it into a flv file, including the process of avformat_write_header(flv_ofmt_ctx, NULL),av_interleaved_write_frame(flv_ofmt_ctx, &p->pkt),av_write_trailer(flv_ofmt_ctx)……
