  • Cannot re-stream RTSP using ffmpeg [closed]

    1er mars 2024, par Wissam Elias

    ffmpeg -loglevel debug -rtsp_transport tcp -i rtsp://192.168.1.13:1935 -rtsp_transport tcp -c:v copy -f rtsp rtsp://127.0.0.1:1935/live/stream


    


    but this usage can connect to the host and reads the packets from the host but it hangs when trying to connect to the local host :

    i want to re stream the rtsp connection from the server to make it available to use this rtsp connection online.

    


  • Qt Video Recorder

    11 mai 2014, par Davlog

    I am trying to create a video recorder with Qt. What I did so far was taking a screenshot of a rectangle on the screen and save it. At the end I use ffmpeg to get a video file out of the images.

    I connected a timer’s signal timeout() to my custom slot which takes the snapshot and saves it to my tmp folder. The timer has an intervall of 1000 / 30. That should be 30 times per second. But 1000 / 30 is a little bit more than 33 milliseconds so I cannot really get 30 fps. It’s a bit more.

    I recorded a youtube video with my recorder and everything was smooth but a little bit faster / slower depending on the intervall.

    So my question basically is how do I get really 30 / 40 / 50 / ... fps ?

  • While transcoding to mpegts ffmpeg creates the first frame after 1.48 seconds delay

    15 mars 2018, par Biraj B Choudhury

    I have transcoded a file to mpegts using the following command

     ./ffmpeg -y -i big_buck_bunny_720p_5mb.mp4  -vcodec libx264  -x264opts "keyint=48:min-keyint=48:no_scenecut" -r 23.976 -c:a copy  -f mpegts test.mpegts

    When I run ffprobe on it -

    ./ffprobe  -i  test.mpegts  -select_streams v -show_frames -of csv

    I see that the first frame starts at 1.48 seconds why is this so ?

    Input #0, mpegts, from 'test.mpegts':

    After some research I added "muxdelay 0" to my command

    ./ffmpeg -y -i big_buck_bunny_720p_5mb.mp4  -vcodec libx264  -x264opts "keyint=48:min-keyint=48:no_scenecut" -r 23.976 -c:a copy  -muxdelay 0 -f mpegts test.mpegts

    And now I get the following in ffprobe

    Input #0, mpegts, from 'test.mpegts':

    Can anybody help me understand what is this muxdelay that is contributing to 1.4 seconds of delay and what is contributing to the remaining 0.08 seconds of delay.

    The first frame is at 0.000 when the output is mp4 so this is something particular to mpegts.
