一. 背景介绍 当我在手机端部署模型时，用mace转模型成功，但是在编译时出错。错误栈给了很多提示，其中一句提示就是：clang++: error: unable to execute command: Killed。 二. 分析问题与解决 该提示指的是内存不够，我的进程操作被杀掉了；解决方法就是增大swap分区的空间。 于是我在网上查找解决方法，运行下面命令即可： sudo fallocate -l 4G /swapfile sudo chmod 600 /swapfile sudo mkswap /sw

以下是针对Python调用FFmpeg将RTSP流（UDP传输）从HEVC转码为H264并封装为MP4格式时出现的不同错误的解决办法： #### 'method SETUP failed: 461 Unsupported transport' 此错误表明服务器不支持UDP传输。可以尝试以下修改： - **尝试其他传输协议**：若服务器不支持UDP，可将传输协议改回TCP。在FFmpeg命令中，将`-rtsp_transport udp`改为`-rtsp_transport tcp`。 ```python import subprocess def transcode_rtsp(): ffmpeg_cmd = [ 'ffmpeg', '-rtsp_transport', 'tcp', '-i', 'rtsp://localhost:8554/t1', '-c:v', 'libx264', '-f', 'mp4', '-movflags', 'frag_keyframe+empty_moov', 'pipe:1' ] return subprocess.Popen(ffmpeg_cmd, stdout=subprocess.PIPE) ``` - **检查服务器配置**：确认服务器是否允许UDP传输RTSP流，可能需要调整服务器的相关设置。 #### 'Could not find ref with POC ...' 该错误通常与HEVC解码过程中的参考帧缺失有关，可尝试以下方法： - **添加解码选项**：在FFmpeg命令中添加`-flags2 +export_mvs`和`-skip_loop_filter all`选项，帮助解码器更好地处理参考帧。 ```python import subprocess def transcode_rtsp(): ffmpeg_cmd = [ 'ffmpeg', '-rtsp_transport', 'udp', '-i', 'rtsp://localhost:8554/t1', '-c:v:0', 'libx264', '-flags2', '+export_mvs', '-skip_loop_filter', 'all', '-f', 'mp4', '-movflags', 'frag_keyframe+empty_moov', 'pipe:1' ] return subprocess.Popen(ffmpeg_cmd, stdout=subprocess.PIPE) ``` - **检查网络稳定性**：不稳定的网络可能导致参考帧丢失，需确保网络连接稳定。 #### 'Could not write header (incorrect codec parameters ?): Invalid argument' 此错误可能是由于编解码器参数不匹配或不正确导致的，可尝试以下操作： - **指定正确的编解码器参数**：确保输出的MP4文件使用正确的编解码器参数，如帧率、分辨率等。 ```python import subprocess def transcode_rtsp(): ffmpeg_cmd = [ 'ffmpeg', '-rtsp_transport', 'udp', '-i', 'rtsp://localhost:8554/t1', '-c:v', 'libx264', '-r', '25', # 指定帧率为25fps '-s', '1920x1080', # 指定分辨率为1920x1080 '-f', 'mp4', '-movflags', 'frag_keyframe+empty_moov', 'pipe:1' ] return subprocess.Popen(ffmpeg_cmd, stdout=subprocess.PIPE) ``` - **检查输入流的完整性**：确保输入的RTSP流正常，没有损坏或缺失关键信息。
