need
When doing EasyDSS development, we are always testing the streaming effect.
Of course, you can use libEasyRTMP for push streaming testing.
Sometimes, we want to use OBS for push testing, that's fine too.
And other RTMP streaming tools.
But don't forget, there is also the artifact ffmpeg. ffmpeg can get various video streams and push them to the EasyDSS RTMP streaming server.
For example, to pull the camera RTSP stream and push it to EasyDSS, the command is here
ffmpeg -i rtsp://username:password@ip:port/xxxxxxx -vcodec copy -acodec copy -f flv -y rtmp://easydssip:easydssport/live/testOf course, this command is limited to the code stream provided by the camera is H.264+AAC, if not
will be -vcodec copychanged -vcodec libx264to-acodec copy-acodec aac
If so, we want to use ffmpeg to read files for RTMP push, of course, you can choose OBS, but, after all, ffmpeg is lighter than OBS, the command is here
ffmpeg -i test.h264 -vcodec copy -acodec copy -f flv -y rtmp://easydssip:easydssport/live/test-vcodec and -acodec are changed as needed to pull RTSP streams.
This satisfies our desire to push files to EasyDSS.
but. . . . .
The effect of ffmpeg streaming is often unsatisfactory, and various problems such as slow playback, asynchronous audio and video, and unstable HLS live broadcast often occur?
solve
Of course there is a solution
ffmpeg -re -stream_loop -1 -i test.h264 -vcodec copy -acodec copy -f flv -y rtmp://easydssip:easydssport/live/testadded one-re
What is this for?
We understand that -re means re-adjusting the timestamp, so that the uneven timestamps of various files, RTSP sources, and RTMP sources can all be re-adjusted by ffmpeg, and then rtmp streaming can be performed to ensure smooth live broadcast and hls slices of uniformity.
In addition, when pulling the RTSP stream, try to add the -rtsp_transport tcp option to ensure the stability of the data source and no packet loss!
