• ffmpeg Could not find input stream [closed]

  17 avril 2013, par Peter Walker

  I've seen lot's of post on streaming video feeds to ffserver but still haven't found what I wanted.

  I use not only on the mp4 file but avi and other formats as well.

      ffmpeg -i test5.mp4 http://localhost:8090/feed1.ffm

  I keep finding this error.

  Can anyone help me figure out some something or something to look for ?
  I tried googling but almost everyone uses video feeds instead or it just works well for them.
  Any clue or direction/suggestion would help. Thank you so much in advance.

• ffmpeg live stream to Youtube command line

  30 juin 2020, par brainoverflowse

  Would anyone assist myself with creating the correct ffmpeg command line for an audio and video rtsp camera feed that is 1440 and scale it to 1080 with a max bitrate of 10000 ?

  


• Is there any way to have a number of video feeds cycle in rotation with ffmpeg ?

  1er novembre 2020, par Brennan

  Is there any way I could take, lets say, 4 live video streams and have them cycle in a rotation on the screen ? I want to take a video feed and play, wait for 5 seconds, go to next video feed, wait 5 seconds, etc...Below is the actual ffmpeg command I want to use and the only idea I have thus far is :

  


  for rotation in $source4 $source5 $source6 $source7; do
    ffmpeg -rtsp_transport tcp -stimeout 100 -i $source1\
           -rtsp_transport tcp -stimeout 100 -i $source2\
           -rtsp_transport tcp -stimeout 100 -i $source3\
           -rtsp_transport tcp -stimeout 100 -i $rotation\
           -filter_complex "nullsrc=size=3840x2160 [base];\
           [0:v] setpts=PTS-STARTPTS [upperleft];\
           [1:v] setpts=PTS-STARTPTS [upperright];\
           [2:v] setpts=PTS-STARTPTS [lowerleft];\
           [3:v] setpts=PTS-STARTPTS [lowerright];\
           [base][upperleft] overlay=shortest=1 [tmp1];\
           [tmp1][upperright] overlay=shortest=1:x=1920 [tmp2];\
           [tmp2][lowerleft] overlay=shortest=1:y=1080 [tmp3];\
           [tmp3][lowerright] overlay=shortest=1:x=1920:y=1080"\
           -c:v h264_nvenc -preset llhq -f matroska - | ffplay -
           sleep 5
    done


  


  As you can see, this would not be very efficient or even usable considering how long it takes to get everything going. If anyone has any ideas I would appreciate it. I am only fluent in Linux shell scripting (Bash) so any other language would be out of my reach at this time. I am defiantly open to suggestions for other tools or frameworks to try. The main goal is to make a script for a group of security cameras with one in the mosaic that rotates through all the additional camera feeds that do not include the 3 already on the screen. It needs to be as low maintenance as possible i.e. a network issue drops connection it should automatically keep checking for connectivity and restart when established. I can do this in a Bash script very easily but getting the videos all up on screen is been a challenge. I considered making completely separate invocations of ffplay for each feed then using wmctrl or similar to arrange them on screen but I am still left with the issue of restarting the rotating one all the time.
