android - android中的视频上传问题

Question

我正在尝试从 SD 卡上传一个 mp4 文件到远程服务器。上传成功，但当我尝试使用 VideoView 通过 url 播放该文件时，它显示“无法播放此视频”。只有使用手机拍摄的视频才会出现此问题，假设我从 watsapp 文件夹上传视频，一切正常，没有任何问题。上传前我需要做任何压缩吗？这是我用来上传视频的代码

 try {
                    FileInputStream fileInputStream = new FileInputStream(sourceFile);
                    URL url = new URL(my url for upload);
                    conn = (HttpURLConnection) url.openConnection();
                    conn.setDoInput(true);
                    conn.setDoOutput(true);
                    conn.setUseCaches(false);
                    conn.setRequestMethod("POST");
                    conn.setRequestProperty("Connection", "Keep-Alive");
                    conn.setRequestProperty("ENCTYPE", "multipart/form-data");
                    conn.setRequestProperty("Content-Type", "multipart/form-data;boundary=" + boundary);
                    conn.setRequestProperty("myFile", fileName);
                    video_name = fileName;
                    video_name = fileName.substring(fileName.lastIndexOf("/")+1);
                    dos = new DataOutputStream(conn.getOutputStream());

                    dos.writeBytes(twoHyphens + boundary + lineEnd);
                    dos.writeBytes("Content-Disposition: form-data; name=\"myFile\";filename=\"" + fileName + "\"" + lineEnd);
                    dos.writeBytes(lineEnd);

                    bytesAvailable = fileInputStream.available();
                    Log.i("ava", "Initial .available : " + bytesAvailable);

                    bufferSize = Math.min(bytesAvailable, maxBufferSize);
                    buffer = new byte[bufferSize];

                    bytesRead = fileInputStream.read(buffer, 0, bufferSize);

                    while (bytesRead > 0) {
                        dos.write(buffer, 0, bufferSize);
                        bytesAvailable = fileInputStream.available();
                        bufferSize = Math.min(bytesAvailable, maxBufferSize);
                        bytesRead = fileInputStream.read(buffer, 0, bufferSize);
                    }

                    dos.writeBytes(lineEnd);
                    dos.writeBytes(twoHyphens + boundary + twoHyphens + lineEnd);

                    serverResponseCode = conn.getResponseCode();
                    Content = conn.getResponseMessage();

                    fileInputStream.close();
                    dos.flush();
                    dos.close();
                } catch (MalformedURLException ex) {
                    ex.printStackTrace();
                } catch (Exception e) {
                    e.printStackTrace();
                }

是的，它可能会发生，因为您的 URL 包含空格，因此您只需要删除空格并设置

%20

insted of white-space like :

URL url1 = new URL(your_url.trim().replace(" ", "%20"));
