To get the best video quality (1080p DASH - format '137') and best audio quality (DASH audio - format '140'), you must use the following command: youtube-dl -f 137+140 You can choose best and type youtube-dl -f 22 Available formats for 3JZ_D3ELwOQ:ġ71 webm audio only DASH webm audio, 48k (worst)ġ40 m4a audio only DASH audio, mp4 192p DASH video 3JZ_D3ELwOQ: Extracting video information 3JZ_D3ELwOQ: Downloading video info webpage Then you can choose to download a certain format-type by entering the number for the format code (in the sample below 11): youtube-dl -f 11 url If you like the article, do not hesitate to hit the clap below to mark your appreciation towards it.To list the available formats type: youtube-dl -F url For converting file formats such as audio, video, image use java.io.ByteArrayInputStream in place of java.io.InputStream in Method 3 above. Using the above methods, all text file formats such as txt, xml, html, csv etc., can be converted to a byte array.

Creation of java.io.RandomAccessFile object may throw a java.io.IllegalArgumentException if the supplied mode is not one among “r”, “rw”, “rws” or “rwd”.A object can also be retrieved from toPath method of java.io.File class as Path path = new File(filePathStr).toPath().It also closes the file in case of any error. readAllBytes method of class closes the file automatically after the file is completely read.read method of java.io.InputStream reads only the number of bytes equal to the size of the byte array.For saving file contents in a database column, the column type in the database should be blob and its java type should be byte.Permissible modes are “r” (reading), “rw” (reading and writing), “rws” (reading and writing file’s content and its metadata to be written to storage) and “rwd” (reading and writing file contents to storage). Creating an object of this class is simple, just pass the path of the file along with the mode in which the file is to be opened.

Method 5 : Using java.io.RandomAccessFileĬlass java.io.RandomAccessFile has a method readFully which takes a byte array as parameter and reads the contents into this array in byte format. Import public static byte convertFileContentToBlob(String filePathStr)īyte fileContent = Files.readAllBytes(filePath) Public static byte convertFileContentToBlob ( String filePath ) throws IOException
