Decoding java objects in python

生来就可爱ヽ(ⅴ<●) 提交于 2019-12-11 10:38:49
问题 Is it possible to decode java objects in python? I know the structure of the java class that returns the data. The data is returned with the header of 'Transfer-Encoding: chunked' Or do I need to get the return data sent as xml / json? This is an example of the response I get; (Note some of the control characters are removed by pasting) -- response -- 200 OK Server: Apache-Coyote/1.1 Transfer-Encoding: chunked Date: Tue, 22 Nov 2011 13:24:41 GMT ��srjava.util.ArrayListx����a�IsizexpGwXsr,com

draw graph of encoded bit rate of video vs play location

China☆狼群 提交于 2019-12-11 08:55:29
问题 I am trying to measure the variation in the bandwidth required when a video is played over the network. For this purpose, i need to make a graph of the bandwidth required to play the video continuously at any time during the video. I tried processing the video with gstreamer but it gives me the bit rate of the decoded[not encoded] video which is more or less constant. Is there a way to get the encoded bit rate of a video over time? 回答1: Since i got no answers here, i will post the solution

GDB print string in an wrong format, a little like octal string

社会主义新天地 提交于 2019-12-11 06:03:33
问题 I show charset in my gdb: The host character set is "UTF-8". The target character set is "UTF-8". The target wide character set is "auto; currently UTF-32". But when I try to output a string in a register p (char*) $register I got a very strange string which hard to recognise: $16 = 0x100001040 "A\020\021\021\033\ndgjhbhnghkb=ejj=h\004\005\b\003 ... I am sure that if the string is purely ascii, all works fine. So what should I do to get the string I want to see? 来源: https://stackoverflow.com

avcodec_decode_video2: what do the extra bytes prevent?

↘锁芯ラ 提交于 2019-12-11 05:05:33
问题 In the documentation for avcodec_decode_video2 it gives the following warning: Warning: The input buffer must be FF_INPUT_BUFFER_PADDING_SIZE larger than the actual read bytes because some optimized bitstream readers read 32 or 64 bits at once and could read over the end. The end of the input buffer buf should be set to 0 to ensure that no overreading happens for damaged MPEG streams. If this were not implemented would this cause segmentation faults when overreading occurs? Or would it

Encode and decode a string, with password and salt, in dotnet core

蓝咒 提交于 2019-12-11 04:06:24
问题 I've been working on a simple helper for dotnet core that should encode and decode a string, based on a user provided password (key) and a salt. In contradiction to the full .NET Framework, dotnet core currently does not have an implementation for the RijndaelManaged class. Pretty much every decent encrypt/decrypt sample for C# is based on this class, rendering it useless for dotnet core. There is a lot of debate on it on the CoreFX repo on GitHub. However, with the combination of both the

Android video encoding and deocding native level

跟風遠走 提交于 2019-12-11 02:33:40
问题 Scenario : I have to read the video frames and edit them and encode it a new .mp4 file. According to the research i have done i can do this native level. Even if i am doing it in the native level which open source library i can use so that the encoding and decoding of the video will be faster. It have seen in many places people used ffmpeg but it in order to H264 stream it needs LGPL license. Is there any other libraries which have better performance and comes under GPL. 回答1: If you can use

Convert .m4a to PCM using libavcodec

倖福魔咒の 提交于 2019-12-10 21:37:15
问题 I'm trying to convert a .m4a file to raw PCM file so that I can play it back in Audacity. According to the AVCodecContext it is a 44100 Hz track using the sample format AV_SAMPLE_FMT_FLTP which, to my understanding, when decodeded using avcodec_decode_audio4, I should get two arrays of floating point values (one for each channel). I'm unsure of the significance of the AVCodecContext's bits_per_coded_sample = 16 Unfortunately Audacity plays the result back as if I have the original track is

Decoding problems in Django and lxml

偶尔善良 提交于 2019-12-10 18:02:10
问题 I have a strange problem with lxml when using the deployed version of my Django application. I use lxml to parse another HTML page which I fetch from my server. This works perfectly well on my development server on my own computer, but for some reason it gives me UnicodeDecodeError on the server. ('utf8', "\x85why hello there!", 0, 1, 'unexpected code byte') I have made sure that Apache (with mod_python) runs with LANG='en_US.UTF-8' . I've tried googling for this problem and tried different
