I'm at a loss on what I'm doing wrong. Im under the assumption I can decode a Plist file the same way I can decode a JSON file right? I don't know, I'm still new to this. //struct for PLists struct AccessControl: Decodable { enum AccessControlKeys: String, CodingKey { case api } enum KeySecretKeys: String, CodingKey { case apiKey = "KEY" case apiSecret = "SECRET" } var KEYS: [KeySecrets]

I tried to decode a series of nal units with ffmpeg (libavcodec) but I get a "no frame" error. I produced the nal units with the guideline at How does one encode a series of images into H264 using the x264 C API? . I tried the following strategy for decoding: avcodec_init(); avcodec_register_all(); AVCodec* pCodec; pCodec=lpavcodec_find_decoder(CODEC_ID_H264); AVCodecContext* pCodecContext; pCodecContext=lpavcodec_alloc_context(); avcodec_open(pCodecContext,pCodec); AVFrame *pFrame; pFrame=avcodec_alloc_frame(); //for every nal unit: int frameFinished=0; //nalData2 is nalData without the first

Passing a $json with up to 500 array elements.... works right! Above that limit... the error is: Warning: Invalid argument supplied for foreach() in /c/website/retriever/WsGlassRetriever.php on line 19 Is there some memory limit for that function's argument? I didn't found nothing about it in the docs. My version is PHP 5.2.17-rnx1.1 with Suhosin-Patch 0.9.7 (cli) 回答1: json_decode

　　NSString的长度问题 pow(2, 15) 为啥要 -19　 　　如下代码产生这个问题： NSMutableString *ms = [NSMutableString string]; for (int i=0; i<pow(2, 15)-19; i++) { [ms appendString:@"1"]; } NSLog(@"%@ %ld", ms, ms.length);// 32749 NSLog(@"%ld", ms.length); [ms appendString:@"1"]; NSLog(@"%@ %ld", ms, ms.length);// 32750 NSLog(@"%ld", ms.length); 　　输出如下： 　　...1111 32749 　　2018-07-25 15:08:27.280985+0800 Demo[30718:219829] 32749 　　...1111 <decode: missing data> 　　2018-07-25 15:08:27.280985+0800 Demo[30718:219829] 32750 　　 　　神一样存在的问题！！！ 原文：https://www.cnblogs.com/pinweyshg/p/9366139.html

Base64是网络上最常见的用于传输字节码的编码方式之一,可用于在HTTP环境下传递较长的信息。如果要通过Http调用tensorflow服务完成图像分类或者检测等任务，就需要用base64来传递图像信息。tensorflow也提供了函数decode_base64来解析图像。 tensorflow decode_base64函数的使用方法如下： def base64_decode_img (b64code) : """ :param b64code:输入为图像的base64编码字符串 :return: """ base64_tensor = tf.convert_to_tensor(b64code, dtype=tf.string) img_str = tf.decode_base64(base64_tensor) #得到（width, height, channel）的图像tensor img = tf.image.decode_image(img_str, channels= 3 ) with tf.Session() as sess: img_value = sess.run([img])[ 0 ] #得到numpy array类型的数据 print(img_value.shape) 使用decode_base64有可能会遇到 invalid character 的异常
