  • Mjpeg text based subtitle extraction/replay

    2 décembre 2013, par user3058117

    I have an MJPEG based avi file that I cannot replay satisfactorily.

    The video I can correctly replay in FFPlay but i cannot replay or demux the text based subtitle stream.

    The file contains time/date stamps in the subtitles embedded as ascii text which i can see between the video packets (when viewed in a hex reader).

    FFmpeg cannot identify the subtitle codec b7t can see that there is a subtitle stream.

    Ive tried a number of filter combinations using GraphStudioNext. I found a couple of working solutions (when previewed in GraphStudio when served to avisynth the subtitles had disappeared again. I checked the filtergraph and the pin out from the avi splitter had misteriously disconnected. I cannot find a way out of this.

    Does anyone have any suggestions on how i might demux the subtitle stream(short of writing a converter to extract the text to srt based on the packet timing) ?

    This is my first post so apologies if i havent observed etiquette.

  • Push to another server based on incoming url

    1er décembre 2020, par Rainmanjam

    Playing around with nginx and wanted to know if there was a way to take an incoming RTMP stream and redirect it to another server based on the URL used. For example :

    


    rtmp ://ingress.foo.com/live/ would forward to rtmp ://.internal.foo.com

    


    Thanks.
