hw_decode.c

"hw_decode.c" 可能是一个 C 语言源代码文件的名称。根据文件名可以猜测，这个文件可能包含了一些硬件解码相关的函数或者代码实现。然而，要想更准确地回答你的问题，我需要更多的上下文信息，例如这个文件属于哪个项目或者库，它的作用和用途是什么等等。如果你能提供更多的信息，我会尽力给出更准确的答案。

java.lang.IllegalStateException: Failed to execute CommandLineRunner at org.springframework.boot.SpringApplication.callRunner(SpringApplication.java:798) [spring-boot-2.3.4.RELEASE.jar:2.3.4.RELEASE] at org.springframework.boot.SpringApplication.callRunners(SpringApplication.java:779) [spring-boot-2.3.4.RELEASE.jar:2.3.4.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:322) [spring-boot-2.3.4.RELEASE.jar:2.3.4.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1237) [spring-boot-2.3.4.RELEASE.jar:2.3.4.RELEASE] at org.springframework.boot.SpringApplication.run(SpringApplication.java:1226) [spring-boot-2.3.4.RELEASE.jar:2.3.4.RELEASE] at com.unkown.data.hw.ipran.straight.collect.UnkownDataHwIpranStraightCollectApplication.main(UnkownDataHwIpranStraightCollectApplication.java:39) [classes/:na] Caused by: feign.FeignException$InternalServerError: [500 INTERNAL SERVER ERROR] during [POST] to [http://ants-flask/api/collect/endpoint] [RemoteIpranScanService#endpoint(String)]: [<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd"> <html> <head> <title>TypeError: unsupported operand type(s) for +: 'int' and 'str' // Wer...

这个错误是由于在执行CommandLineRunner时出现了异常。具体原因是发生了500内部服务器错误，原因是POST到http://ants-flask/api/collect/endpoint的RemoteIpranScanService#endpoint(String)出现了问题。在调用com.unkown.data.hw.ipran.straight.collect.controller.RTrsHwIpranCircuitController.IpranSend(RTrsHwIpranCircuitController.java:94)和com.unkown.data.hw.ipran.straight.collect.MyRunner.run(MyRunner.java:22)时也出现了问题。建议检查代码中的POST请求和响应处理是否正确，或者检查远程服务器是否正常。

ffmpeg音频解码av_frame_alloc

av_frame_alloc函数用于为AVFrame结构体分配内存空间，AVFrame结构体用于存储解码后的音视频数据。在音频解码中，可以通过调用该函数为AVFrame结构体分配内存空间，然后将解码后的音频数据存储到该结构体中，最后再进行后续的处理操作。具体使用方法如下： ```c AVFrame *frame = av_frame_alloc(); if (!frame) { // 内存分配失败处理 } ``` 其中，AVFrame结构体的定义如下： ```c typedef struct AVFrame { /** * pointers to the data planes/channels. * This might be different from the first allocated byte */ uint8_t *data[AV_NUM_DATA_POINTERS]; /** * For video, size in bytes of each picture line. * For audio, size in bytes of each plane. */ int linesize[AV_NUM_DATA_POINTERS]; /** * pointers to the start of each picture line. * This is used for both video and audio. */ uint8_t **extended_data; /** * width and height of the video frame */ int width, height; /** * number of audio samples (per channel) described by this frame */ int nb_samples; /** * format of the frame, -1 if unknown or unset * Values correspond to enum AVPixelFormat for video frames, * enum AVSampleFormat for audio) */ int format; /** * 1 -> keyframe, 0-> not */ int key_frame; /** * Picture type of the frame. */ enum AVPictureType pict_type; /** * Quality (between 1 (good) and FF_LAMBDA_MAX (bad)). */ int quality; /** * for AV_PIX_FMT_*_BE formats, linesize alignment */ int64_t best_effort_timestamp; /** * PTS copied from the AVPacket that was decoded to produce this frame. */ int64_t pkt_pts; /** * DTS copied from the AVPacket that triggered returning this frame. */ int64_t pkt_dts; /** * duration of the corresponding packet, expressed in * AVStream->time_base units, 0 if unknown. */ int64_t pkt_duration; uint64_t metadata; int decode_error_flags; /** * number of audio channels */ int channels; /** * size of the corresponding packet containing the compressed * frame. It is set to a negative value if unknown. */ int pkt_size; /** * data type */ enum AVSampleFormat sample_fmt; /** * presentation timestamp in timebase units * (time when frame should be shown to user) * If AV_NOPTS_VALUE then frame_rate = 1/time_base will be assumed. */ int64_t pts; /** * reordered PTS from the last AVPacket that has been input into the decoder */ int64_t best_effort_timestamp; /** * sample aspect ratio (0 if unknown) * - encoding: Set by user. * - decoding: Set by libavcodec. */ AVRational sample_aspect_ratio; /** * motion vector table, used for MPEG1/2/4 and H.263 decoding */ struct AVPanScan *pan_scan; /** * macroblock decision mode */ int coded_picture_number; int display_picture_number; /** * quality (between 1 (good) and FF_LAMBDA_MAX (bad)) */ int quality; /** * buffer age (1->was last buffer and dint change, 2->..., ...) */ int age; /** * is this picture used as reference */ int reference; /** * QP table */ int8_t *qp_table_buf; /** * QP store stride */ int qp_table_linesize; /** * QP values for each macroblock */ int8_t *qp_table; /** * For hwaccel-format frames, this should be a reference to the * AVHWFramesContext describing the frame. * For normal-format frames, this should be NULL. */ AVBufferRef *hw_frames_ctx; } AVFrame; ``` 需要注意的是，AVFrame结构体中的成员变量很多，具体使用哪些成员变量取决于具体的应用场景和需求。
