This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...) -

Using ffmpeg and ffserver to create a 2x1 live stream fails with unconnected output error
31 janvier 2021, par weevilknievelI want to combine 2 RTSP streams (CCTV cameras) into a horizontal 2x1 strip and convert to webm for use in a HTML5 webpage.



I am able to convert the streams into an mpeg or avi file easily, but as soon as I try to post it to ffserver ffm feed, I hit a wall.



Here is my working ffmpeg command which writes out to a file :



ffmpeg -rtsp_transport tcp -thread_queue_size 12 -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=1&stream=1.sdp" -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=2&stream=1.sdp" -filter_complex "[0:v][1:v] hstack=inputs=2 [v]" -map "[v]" -r 30 output.mpg



It seems the ffmpeg process is outputting two streams and one of them is MPEG ? In the above command I had to put a frame rate "-r 30" into the command otherwise I got an error which said that MPEG 1/2 did not support a framerate of 5/1 ??



As soon as I try and stream to ffserver, I get an error :



ffmpeg -rtsp_transport tcp -thread_queue_size 12 -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=1&stream=1.sdp" -i "rtsp://192.168.1.132:554/user=admin&password=mypassword&channel=2&stream=1.sdp" -filter_complex "[0:v][1:v] hstack=inputs=2 [v]" -map "[v]" -r 30 http://localhost:8090/feed5.ffm



The error I get is "Filter hstack has an unconnected output" :

ADD Image overlay to ffmpeg video stream
1er juillet 2017, par ChrisI am new to ffmpeg and want to add an HUD to the video stream, so a few questions.
- What file do I need to edit.
- What do I need to do to achieve this.
Thanks in advance. Also I am VERY new to all of this, I will need instructions step by step
I saw other questions saying to add this :
ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4But I dont know where to put it, i entered it in the terminal and got this :
pi@raspberrypi:~ $ ffmpeg -n -i video.mp4 -i logo.png -filter_complex "[0:v]setsar=sar=1[v];[v][1]blend=all_mode='overlay':all_opacity=0.7" -movflags +faststart tmb/video.mp4
