FFmpeg 到 Azure 媒体服务平滑流式输入
FFmpeg to Azure Media Services Smooth Streaming Input
我想询问使用平滑流式传输/isml 协议将 mp4 片段转换为 Azure 媒体服务实时事件的 ffmpeg 配置或命令。 AMS 尚未从 ffmpeg 获得任何输入。
这是我当前的 运行 命令：
ffmpeg -f dshow -i video="Webcam" -movflags isml+frag_keyframe -f isml -r 10 http://endpoint/ingest.isml/streaming1
当我将 RTMP 与 Wirecast 一起使用时 运行 很好。
对使用 isml 协议的 ffmpeg 命令有什么建议吗？
谢谢
这可能是您格式化摄取的方式 URL。 Smooth 摄取协议需要 /Streams(yourtrackname-identifier) 的名称。

这是我曾经使用过的一个 FFMPEG 命令行，它曾经在 Raspberry Pi 上为我工作
ffmpeg -i /dev/video1 -pix_fmt yuv420p -f ismv -movflags isml+frag_keyframe -video_track_timescale 10000000 -frag_duration 2000000 -framerate 30 -r 30 -c:v h264_omx -preset ultrafast -map 0:v:0 -b:v:0 2000k -minrate:v:0 2000k -maxrate:v:0 2000k -bufsize 2500k -s:v:0 640x360 -map 0:v:0 -b:v:1 500k -minrate:v:1 500k -maxrate:v:1 500k -s:v:1 480x360 -g 60 -keyint_min 60 -sc_threshold 0 -c:a libfaac -ab 48k -map 0:a? -threads 0 "http://johndeu-nimbuspm.channel.mediaservices.windows.net/ingest.isml/Streams(video)"
请注意，我使用了以下流标识符 - 摄取。isml/Streams（视频）
这里还有一些可能有用的命令。
