  • restreaming with ffmpeg and ffserver

    13 mars 2014, par Dnaso

    I have been looking all over stack and the net and cannot find the answer (or one that works for me anyway). I have a cerevo liveshell pro which is a video encoder (pretty damn good too). In its RTSP server mode, I am able to watch audio and video on iphone and android. However, It can only hold 3 connections. I want to restream this stream NO encoding of any type on ffserver. Is this possible ? Everything I have tried so far does not open. If I disable my audio in the config file it works and if i disable video and just push audio it works, but both will not. Also I do not want to use ffmpeg if I do not have to because I am not re encoding the stream, since it is already encoded in the correct format, I just want to restream it !.

     ffmpeg -i rtsp://xxx  -vcodec copy -acodec copy http://lclhst:8090/feed1.ffm
    

    

    
<stream>
    
   format rtp
    
   videoCodec libx264
    
   AudioCodec aac
    
    I also have global headers for audio and video.
    
</stream>

    has anyone been able to fix or surpass the issue ?

  • Change the framerate of a video including audio without re-encoding using ffmpeg

    12 août 2018, par Trojaner_

    I have a 30.02 FPS .mp4-video and I’m trying to convert it to 30 FPS. I found this question but if I try the method like described in the first answer the audio gets lost because the video is getting converted in a .h264-file which can’t contain audio as I read here.

    (I’m sorry if i’ve got issues with the english language, it isn’t my mother language)

    EDIT : Here goes the content I enter in the terminal and the output that returns

    Input : ffmpeg -y -i 01.mp4 -f h264 -c copy temp1.h264

    Output : (I replaced the real paths with path\to\...)

  • How create synth with FFMPG ?

    1er novembre 2022, par Seb

    I am looking for the creation of a synth (synthé in french) with FFMPEG. For more explanation, a synth is a rectangle on a movie, where you can write text. In France, we had a very good science program on TV which have an example of the synth I'd like : https://www.youtube.com/watch?v=HR7HojWY-kg from 11:50 to 11:54 where it is written "Dr Luc DE HARO". As this example, I'd like to add on the left a image. I am looking for weeks to do that but I can't realise this synth. Could you help me please ?
