codec

I have a text file with first line of unicode characters and all other lines in ASCII. I try to read the first line as one variable, and all other lines as another. However, when I use the following code: # -*- coding: utf-8 -*- import codecs import os filename = '1.txt' f = codecs.open(filename, 'r3', encoding='utf-8') print f names_f = f.readline().split(' ') data_f = f.readlines() print len(names_f) print len(data_f) f.close() print 'And now for something completely differerent:' g = open(filename, 'r') names_g = g.readline().split(' ') print g data_g = g.readlines() print len(names_g)

In Python, what is the best way to write to a UTF-8 encoded file with platform-dependent newlines? the solution would ideally work quite transparently in a program that does a lot of printing in Python 2. (Information about Python 3 is welcome too!) In fact, the standard way of writing to a UTF-8 file seems to be codecs.open('name.txt', 'w') . However, the documentation indicates that (…) no automatic conversion of '\n' is done on reading and writing. because the file is actually opened in binary mode. So, how to write to a UTF-8 file with proper platform-dependent newlines? Note: The 't' mode

no matter what "CV_FOURCC" I use I get this: OpenCV Error: Unsupported format or combination of formats (Gstreamer Opencv backend doesn't support this codec acutally.) in CvVideoWriter_GStreamer::open, file /usr/src/packages/BUILD/OpenCV-2.2.0/modules/highgui/src/cap_gstreamer.cpp, line 489 writer = cv.CreateVideoWriter( filename=file, fourcc=cv.CV_FOURCC('F', 'M', 'P', '4') , fps=iFps, frame_size=(800,600), is_color=1) cv.WriteFrame(writer, cv.LoadImage(frames[i])) Also /usr/src/packages/BUILD/OpenCV-2.2.0/modules/highgui/src/cap_gstreamer.cpp, does not exist. Also CV_FOURCC('H','F','Y','U')

I created a h264 raw video file, and I was able to mux it with Android MediaMuxer on Android 4.3 and up. Now I need to support Android versions 4.1 and 4.2. I found Jcodec. And there is an example for doing this: https://github.com/jcodec/jcodec/blob/master/samples/main/java/org/jcodec/samples/mux/AVCMP4Mux.java But I'm getting java.nio.ReadOnlyBufferException exception at line 70: H264Utils.encodeMOVPacket(data); I guess this code is not for Android? How do I fix this. Can someone familiar with Jcodec help on this? xy uber.com I gave up on Jcodec. It exposes too many codec internal stuff, and

I looked everywhere here and on google - there is no valid command that works for IE9. some how IE9 is missing something. All that I tried worked everywhere else: chrome,safari,mobile device etc... I want one command that will convert it and I can use it in every device suppose to support mp4 in HTML5 video tag. I use this commands: ffmpeg -i movie.mov -vcodec copy -acodec copy out.mp4 ffmpeg -i movie.mov -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k -pix_fmt yuv420p outa.mp4 ffmpeg -i movie.mov -b

Is there a way to create a video from a series of images on android? Maybe a way to extend the MediaRecorder and being able to take images as input. I try to really create the video and store it (as an mpeg4 file for instance). Thanks for any suggestions. Showpath I'm also trying to do the same thing. I have been advice to use Libav. http://libav.org/ However I need to build it with the NDK and I currently have some issues doing it. I'm looking for some doc about it. I'll keep you posted. I've created a post about it: Libav build for Android You can use AnimationDrawable in an ImageView . Add

We have an option to check the network connection types in Android (whether it is 3G, edge or gprs). I need to check the the bandwidth rate. I need to initiate a call. For that I need to check the bandwidth rate. Above a particular bandwidth only I need to make visible an option for a call (to initiate a call). I need to find the connection speed programmatically (connection speed for Mobile Data Link, EDGE). You can download a known-size file from your server, and calculate how long did it take to download it. Then you have your bandwidth. Simple but works :) Sample, not tested : //Download
