Processing of multipart/form-data request failed. Unexpected EOF read on the socket
23 mai 2017, par RaresI am trying to upload a video file to the server(
Spring Boot) from android.A video filmed with the phone has >50 MB if you film at least 2 minutes so I have to compress the file before uploading.
Before compressing I tried to upload uncompressed files and it worked fine(10-30MB videos). Now I want to compress files because I want to send bigger videos to the server.
I use multipart/form-data in android to send the file to the server.EDIT :
protected void onActivityResult(int requestCode, int resultCode, final Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if (requestCode == REQUEST_PICK_VIDEO && resultCode == RESULT_OK && data != null) {
progressDialog = new ProgressDialog(MainActivity.this);
progressDialog.setTitle("Uploading");
progressDialog.setMessage("Please wait...");
progressDialog.show();
Thread thread = new Thread(new Runnable() {
@Override
public void run() {
String filePath = getRealPathFromURI(getApplicationContext(), data.getData());
///get the name of file without extension
StringBuilder stringBuilder = new StringBuilder(filePath);
int start = filePath.lastIndexOf('.');
stringBuilder.delete(start, filePath.length());
//--------------
//get file extension(e.g mp4)
File file = new File(filePath);
String contentType = getFileType(file.getAbsolutePath());
//--------------
//create compressed file path=initial file path+ _compressed+(random nr.)+ extension .mp4
Random random = new Random();
int fileNr = random.nextInt(999);
String compressedFilePath = stringBuilder.toString() + "_compressed" + fileNr +"."+ contentType;
//compress file from gallery and save it with the above name
String[] command = {"-y", "-i", filePath, "-s", "640x480", "-r", "25", "-vcodec",
"mpeg4", "-b:v", "150k", "-b:a", "48000", "-ac", "2", "-ar", "22050", compressedFilePath};
executeFFmpegBinary(command);
File file2 = new File(compressedFilePath);
if (file2.exists()) {
OkHttpClient httpClient = new OkHttpClient();
RequestBody fileBody = RequestBody.create(MediaType.parse(contentType), file2);
RequestBody requestBody = new MultipartBody.Builder()
.setType(MultipartBody.FORM)
.addFormDataPart("type", contentType)
.addFormDataPart("uploaded_file", file2.getName(), fileBody)
.build();
Request request = new Request.Builder()
.url(SERVER_ADDRESS_UPLOAD)
.post(requestBody)
.build();
try {
final Response response = httpClient.newCall(request).execute();
if (!response.isSuccessful()) {
printFromThread(response.toString());
throw new IOException("Error: " + response);
} else {
printFromThread(response.body().string());
}
progressDialog.dismiss();
} catch (IOException e) {
e.printStackTrace();
}
}
}
});
thread.start();
}
}When I use FFmpeg compression and I send the compressed file to the server I receive the following error in the server :
Processing of multipart/form-data request failed. Unexpected EOF read on the socketServer bean :
@RequestMapping(value = "/upload-image", method = RequestMethod.POST)
@ResponseBody
public String handleUploadImageRequest(@RequestParam("uploaded_file")
MultipartFile file) throws IOException {
File fileReceived = new File(VIDEOS_DIR+"/"+file.getOriginalFilename());
fileReceived.createNewFile();
FileOutputStream fileOutputStream = new FileOutputStream(fileReceived);
fileOutputStream.write(file.getBytes());
fileOutputStream.close();
prelucrareVideo(fileReceived);
return "....";}

FFmpeg decoded video is garbled mess with no audio. How can I fix it ? [closed]
14 septembre 2023, par Señor TontoI am trying to use FFmpeg 6.0 (which seems to have a terrible lack of documentation) to decode a .mp4/.mov file & play its audio. I am testing this on a .mov file (I tried also with a .mp4, same result) of an old animation I found. This turns out as a garbled mess that looks like an old film movie with no audio. Now, I used some old tutorials & managed to with much trial get the code I have now, which is of course half-working. I am using SDL to output the video. I'm not sure if it's a problem on the SDL end or the FFmpeg end at the moment (but I'm sure the video is a mix of the two & the audio because of SDL) I would appreciate some help as there's very little documentation I can find that isn't outdated & the deprecated list on FFmpeg hardly helps when I need to fix API-related changes. Here's my code
