python - Streaming files with cherrypy -


i trying stream video file using cherrypy. when go localhost:8080/stream?video=video.avi starts downloading, after few seconds "completes" download no matter how large file is. i'm rather new , cannot find out why doing that. also, why doesn't recognize file if matroska (.mkv) ?

here stream class:

class stream(object): @cherrypy.expose def default(self, video=none):     base_path = ".."     video = os.path.join(base_path, video)     if video == none:         return "no file specified!"     if not os.path.exists(video):         return "file not found!"     f = open(video)     size = os.path.getsize(video)     mime = mimetypes.guess_type(video)[0]     print(mime)     cherrypy.response.headers["content-type"] = mime     cherrypy.response.headers["content-disposition"] = 'attachment; filename="%s"' % os.path.basename(video)     cherrypy.response.headers["content-length"] = size      buf_size = 1024 * 5      def stream():         data = f.read(buf_size)         while len(data) > 0:             yield data             data = f.read(buf_size)      return stream() default._cp_config = {'response.stream': true}

i realised needed change open(video) open(video, 'rb') read file in binary mode. after file downloaded , worked.

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
