decoding

问题 I have the problem that the decoding from a URL causes some major problems. The request URL contains %C3%BC as the letter 'ü'. The decoding server side should now decode it as an ü, but it does this: ü decoding is done like this: decoded = URLDecoder.decode(value, "UTF-8"); while value contains '%C3%BC' and decoded should now conatain 'ü', but that's where the problem is. What's going wrong here? I use this method in more than one application and it works fine in all other cases... 回答1: I

问题 I'm working on an embedded device that does not support unaligned memory accesses. For a video decoder I have to process pixels (one byte per pixel) in 8x8 pixel blocks. The device has some SIMD processing capabilities that allow me to work on 4 bytes in parallel. The problem is, that the 8x8 pixel blocks aren't guaranteed to start on an aligned address and the functions need to read/write up to three of these 8x8 blocks. How would you approach this if you want very good performance? After a

问题 I'm trying to configure a reverse proxy from Apache web server (A) to another Apache web server on different machine (B). With configuration I'm currently using I'm able to access web page located on server B as if it were on server A, however requests for some assets constantly result in ERR_CONTENT_DECODING_FAILED (at least in chrome). This doesn't happen when I'm using simple redirection instead of proxying. I have browsed through request and response headers and it seems that everything

问题 First, I want to let everyone know that I am using an aspx engine not a Razor engine. I have a table within a form. One of my textbox contains html tags like </br>Phone: </br> 814-888-9999 </br> Email: </br> aaa@gmail.com. When i go to build it it it gives me an error that says A potentially dangerous Request.Form value was detected from the client (QuestionAnswer="...ics Phone:<br/>814-888-9999<br...") . I tried the validation request="false" but it did not work. Im sorry i didn't add my

问题 I use web service to get image. The service response contains image in base64Binary format. I try to decode response data with Base64.decode() (http://iharder.sourceforge.net/current/java/base64/). See my code below: byte[] data = Base64.decode(responseString); Bitmap bmp = BitmapFactory.decodeByteArray(data, 0, data.length); imageView.setImageBitmap(bmp); decodeByteArray always return null. I try to save data in .png file. I can open this file on my PC and in the Android File Manager

问题 I want to decode and then encode a video file. The example I found on bigflakes is using the Inputsurface for decoding. I want to directly provide the decoded data to the encoder as input. I am getting error that the output buffer from decoder is null, when I provide that as input to the encoder. Any suggestions ?
