How to use JavaScript to decode from: \u003cb\u003estring\u003c/b\u003e to <b>string</b> (I searched in internet, there are some site with same question, such as: Javascript html decoding or How to decode HTML entities but it dont have same encode fomat ) Thank you very much! decodeURIComponent('\u003cb\u003estring\u003c/b\u003e'); // "<b>string</b>" Edit - I would delete the above answer if I could. The original question is a bit ambiguous. console.log('\u003cb\u003estring\u003c/b\u003e'); will already yield <b>string</b> If the \ characters are escaped, then a replacement method could be

问题 It's difficult to tell what is being asked here. This question is ambiguous, vague, incomplete, overly broad, or rhetorical and cannot be reasonably answered in its current form. For help clarifying this question so that it can be reopened, visit the help center. Closed 7 years ago . I am able to get the RGBA frame data from the camera, and I want to encode it in H.264 format. I've used FFmpeg to encode and decode H.264 video, but at a frame size of 640x480 it's too slow for my needs. I'd

Android MediaCodec decode h264 raw frame

I am using Android MediaCodec API to decode h264 frames. I could decode and render the frames on the view. My problem is the decoder miss lots of frames,especially the first some frames. DecodeMediaCodec.dequeueOutputBuffer() return -1. aAbout 150 h264 frames,just decoded 43 frames. I can not find where the problem is. Here is my codes. /** * init decoder */ private void initDecodeMediaCodec() { mDecodeMediaCodec = MediaCodec.createDecoderByType(MIME_TYPE); MediaFormat format = MediaFormat.createVideoFormat(MIME_TYPE, VIDEO_WIDTH_640, VIDEO_HEIGHT_480); mDecodeMediaCodec.configure(format, new

Here what I did achieve so far: char *in = data; char *buffer; unsigned int i; unsigned char mask[4]; unsigned int packet_length = 0; int rc; /* Expect a finished text frame. */ assert(in[0] == '\x81'); packet_length = ((unsigned char) in[1]) & 0x7f; mask[0] = in[2]; mask[1] = in[3]; mask[2] = in[4]; mask[3] = in[5]; if (packet_length <= 125) { **// This decoding works** /* Unmask the payload. */ for (i = 0; i < packet_length; i++)

Perl: utf8::decode vs. Encode::decode

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效,请关闭广告屏蔽插件后再试): 问题: I am having some interesting results trying to discern the differences between using Encode::decode("utf8", $var) and utf8::decode($var) . I've already discovered that calling the former multiple times on a variable will eventually result in an error "Cannot decode string with wide characters at..." whereas the latter method will happily run as many times as you want, simply returning false. What I'm having trouble understanding is how the length function returns different results depending on which method you use to decode. The problem

What I've Tried: I've searched around online and I've seen several similar issues but not mine. I've attempted their solutions including Uninstalling and reinstalling ImageMagick via brew. identify -list format (JPEG, GIF, PNG, TIFF, etc were all there and all had rw permissions) convert -version (png is is among the built-in delegates) convert pic1.png pic1-jpg.jpg (this worked fine) convert pic1-jpg.jpg pic1-jpg.jpg (this worked fine)

Example of both will really help. I understand how Java bytecode works and how an assembly language works. But where does DDI and TI fit in? Context: Virtual machines: versatile platforms for systems and processes 回答1: (Note: I'll assume that by "decode and dispatch" you mean a switch-based interpreter.) The difference between a switch-based and a threaded interpreter at run time is,

However, this one had a response header: GZIP encoding, and when I tried to print the source code of this web page, it had all symbols in my putty. How do decode this to regular text? 回答1: I use zlib to decompress gzipped content from web. import zlib ... # f=urllib2.urlopen(url) decompressed_data=zlib.decompress(f.read(), 16+zlib.MAX_WBITS) 回答2: Decompress your byte stream using the built-in gzip module. If you have any problems, do show the exact minimal code that
