Audio FFMPEG未从RTSP流中录制音频
我正在尝试以HLS格式记录rtsp流。我需要录音和录像。使用下面的命令，视频和音频会被录制成一些流，比如来自互联网的测试rtsp流。至于我的IP摄像头，它不工作，这意味着视频被录制，但输出文件中没有音频Audio FFMPEG未从RTSP流中录制音频,audio,video,ffmpeg,rtsp,Audio,Video,Ffmpeg,Rtsp,我正在尝试以HLS格式记录rtsp流。我需要录音和录像。使用下面的命令，视频和音频会被录制成一些流，比如来自互联网的测试rtsp流。至于我的IP摄像头，它不工作，这意味着视频被录制，但输出文件中没有音频 ./ffmpeg -i rtsp://10.0.8.152:554/media/live/1/1 -acodec copy -vcodec copy -hls_list_size 65535 -hls_time 2 "./live.m3u8" 这是我的IP摄像头在使用上述命令开始录制时的命令行

MPEG-TS流支持有限数量的音频编解码器，PCM a-law似乎不是其中之一 AAC是可接受的，可按如下方式使用：
