我正在尝试使用 FFMPEG x265 对视频进行编码，将其放入 MPEG2 TS，然后通过 UDP 流式传输。然后在另一台电脑上接收并保存。执行 PSNR。
编码工作正常，但是当我尝试流式传输时出现错误：
[mpegts @ 00000000050b0520] HEVC 比特流错误，缺少起始码，大小 1436 数据 00000100
- 第 1 步 - 编码：
ffmpeg -re -i test.ts -r 25 -b:v 2500k -preset medium -c:v libx265 -x265-params crf=27 -y -f mpegts test1.ts
没有错误，一切正常。
- 第 2 步 - 流式传输：
缺少启动代码。
ffmpeg -re -i test1.ts -c copy -f mpegts udp://172.18.60.47:1234

当我使用 x264 执行上述步骤时，一切正常。我可以流式传输视频，我可以在另一端接收它。知道有什么问题吗？这是一个BUG吗？
x264 的命令：
ffmpeg -re -i test.ts -r 25 -b:v 2500k -preset medium -c:v libx264 -x264-params crf=27 -y -f mpegts test1.ts
ffmpeg -re -i test1.ts -c 复制 -f mpegts udp://172.18.60.47:1234
谢谢您的帮助！！
