I’ve finally found an answer. There is such option as -sn which disables subtitles decoding from input stream. Also there are analogous options for audio and video decoding: -an and -vn respectively. It also turned out that there is another way to achieve this. One may use the -map option to select which streams are … Read more
Sink and Stream both are parts of the StreamController. You add a data to the StreamController using Sink which can be listened via the Stream. Example: final _user = StreamController<User>(); Sink get updateUser => _user.sink; Stream<User> get user => _user.stream; Usage: updateUser.add(yourUserObject); // This will add data to the stream. Whenever a data is added … Read more
This is one of my favorite tuck-away functions I keep on hand for multiple uses. #include <sys/stat.h> // Function: fileExists /** * Check if a file exists * * @param[in] filename – the name of the file to check * * @return true if the file exists, else false */ bool fileExists(const std::string& filename) { … Read more
In order to read the JSON incrementally, you’ll need to use a JsonTextReader in combination with a StreamReader. But, you don’t necessarily have to read all the JSON manually from the reader. You should be able to leverage the Linq-To-JSON API to load each large object from the reader so that you can work with … Read more
There’s a plugin for capturing the camera stream, It uses AVCaptureVideoDataOutput to create a capture session. Each frame is base64 encoded and passed to the Cordova UIWebView. Its experimental and is slower than any native approach.
The average decent servletcontainer itself flushes the stream by default every ~2KB. You should really not have the need to explicitly call flush() on the OutputStream of the HttpServletResponse at intervals when sequentially streaming data from the one and same source. In for example Tomcat (and Websphere!) this is configureable as bufferSize attribute of the … Read more
Here’s a solution that combines some of the good ideas already presented. Create a function in a bash script: color() ( set -o pipefail; “$@” 2>&1>&3 | sed $’s,.*,\e[31m&\e[m,’ >&2 ) 3>&1 Use it like this: $ color command -program -args It will show the command’s stderr in red. Keep reading for an explanation of … Read more
Well, the simplest way is: file.InputStream.Position = 0; … assuming the stream supports seeking. However, That may do interesting things to the Image if you’re not careful – because it will have retained a reference to the stream. You may be best off loading the data into a byte array, and then creating two separate … Read more
I think the answers referencing a FileChannel are on the mark . Here’s a sample implementation of an input stream that encapsulates this functionality. It uses delegation, so it’s not a true FileInputStream, but it is an InputStream, which is usually sufficient. One could similarly extend FileInputStream if that’s a requirement. Not tested, use at … Read more
That’s a funny question you have! In fact, buffered vs piped is not the question here. You have a small chunk; it is processed in one event. To show the issue at hand, you can write your handler like this: let chunk; req.on(‘data’, (dt) => { chunk=dt }); req.on(‘end’, () => { res.write(chunk); res.end(); }); … Read more
