Hi Moritz, I am having some issues regarding changing the fps of the streamed video.
I am applying the following ffmpeg command on the terminal which has 30 fps in the output and pushes the stream to wowza server. ffmpeg -re -i ~/Videos/Movie/Chhello\ Divas\ 2015.mp4 -acodec copy -r 30 -f rtsp -muxdelay 0.01 rtsp://mahek:Mahek@123@ 192.168.201.76:1935/live/mystream During the execution of the above command, i am applying the below command simultaneously in other terminal which has 15 fps in the output. ffmpeg -re -i ~/Videos/Movie/Chhello\ Divas\ 2015.mp4 -acodec copy -r 15 -f rtsp -muxdelay 0.01 rtsp://mahek:Mahek@123@ 192.168.201.76:1935/live/mystream I am able to see that fps gets changed in the second terminal but I am not able to see the video in vlc in any of the above command ( vlc just plays the audio stream, video stream is not present). Following are my queries regarding changing the fps of the streamed video : 1. What can I do so that I am able to see the video track in vlc ? 2. When I am entering the second command it starts from 00:00:00 time, so how can I check the exact instance of time at which change in fps has resulted in video ? (for example if I am having 10 min video and I have entered first command, it starts streaming now after 5 minutes I am applying second command in another terminal it also starts with 00:00:00 time now. Actually, FPS Changes effect must come from the 5 mintues(the time at which i executed fps chagne command) only, Video plying must not be start from the beginning.)
