如何仅发送视频 (mp4) 以流式传输到 kinesis-video-stream
How to send only video (mp4) to stream to kinesis-video-stream
当我尝试发送我从互联网上下载的视频样本时，它同时具有 AAC 和 H-264 编解码器，以下命令工作正常。但是当我使用 OpenCV 生成 mp4 文件时，它只有 H-264 编解码器而没有 AAC，因为没有音频，它给我以下错误。
命令：
gst-launch-1.0 -v filesrc location="YourAudioVideo.mp4" ! qtdemux name=demux ! queue ! h264parse ! video/x-h264,stream-format=avc,alignment=au ! kvssink name=sink stream-name="audio-video-file" access-key="YourAccessKeyId" secret-key="YourSecretAccessKey" streaming-type=offline demux. ! queue ! aacparse ! sink.

您显然删除了管道中的 AAC 部分：
