我正在尝试通过udp流式传输带有ffMpeg的电视调谐器提要。
我使用的ffMpeg命令行如下:ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/
地点:
- 1317为程序id(通道)
- 10.150.112.107是我想要流的电视频道
- 239.255.255.9是我从电视调谐器 接收原始电视频道的馈送的地方
我的问题是，与一些程序id它是工作的，而与其他一些它不是:它是与1572 ("频道10 hd")工作，但不与1317 ("7flix悉尼")。
通道1572的命令行输出如下:

谢谢你的帮助
您假设程序的前两个基本流是视频和音频，但情况可能并非如此，而这正是这里发生的事情。您最终映射了视频和一些无法转码的未知数据流。
不幸的是，它是不可能要求ffmpeg"这个程序的第一个视频流"- -map不够聪明，解析程序说明符和流类型说明符。在您的情况下，只有一个视频和一个音频流，所以您应该能够做以下操作:-map 0:p:1317 -ignore_unknown -map -d -map -s，即从程序中映射所有内容，然后删除未知，数据和字幕轨道。
