Here is command:
ffmpeg -i rtmp://localhost/myapp/obs -c:a libfdk_aac -b:a 32k -c:v libx264 -f flv rtmp://localhost/hls/obs_low
My RTMP server records all published streams, so I can view them all. Strange thing is, while rtmp://localhost/myapp/obs
is streaming, if I run the above ffmpeg command, it's only audio in output file, no video. And in terminal output:
Stream mapping:
Stream #0:0 -> #0:0 (aac (native) -> aac (libfdk_aac))
But if I run same command again, there could be the video. Randomly, video is there or not. If video is there, I see this output in terminal:
Stream mapping:
Stream #0:1 -> #0:0 (h264 (native) -> h264 (libx264))
Stream #0:0 -> #0:1 (aac (native) -> aac (libfdk_aac))

Just now run above ffmpeg command 20 times in a row. There was video only 12 times. 8 times = just audio. – user3278087 – 2016-08-11T13:39:16.847
Sounds like interleaving gap is large. Try with
-analyzeduration 1G -probesize 50M

what is full console output? If it's MPEG then eah you might need larger analyzeduration – rogerdpack – 2016-08-17T15:39:18.410
