  • Implement a simple MPEG-TS muxer using ffmpeg-lib

    1er novembre 2019, par Pierre P.

    I have an application that records raw audio data in LPCM stored in a buffer. I would like to encapsulate the data in a transport stream and send that transport stream through UDP to a stream segmenter (according to HTTP Live Streaming specifications) on another host.

    FFmpeg provides a command-line utility to do so but with a file as input
    ffmpeg -re -i output.aac -acodec copy -f mpegts udp://127.0.0.1:5555.

    My first thought was to use FFmpeg API, especially the libavformat library. Does libavformat provide a muxer that I could use to encapsulate my audio in LPCM into a transport stream or do I have to implement it from scratch ?

    I have found this source code https://github.com/FFmpeg/FFmpeg/blob/master/libavformat/mpegts.c but I am not sure if it actually does what I’m looking for.

    Thanks for your help,

  • writing simple linux bash program to trim video using ffmpeg [closed]

    12 août 2020, par feri ariyatmoko
      


    1. I know I can trim video using ffmpeg without re-encoding it using this following command :ffmpeg -i 'inputvideo.mp4' -vcodec copy -acodec copy -ss 00:09:33 -to 00:11:53 'output.mp4'

      


      2. 


    2. I've tried that command, it worked like a charm.

      


      3. 


    3. Since I will trim a lot of videos, I think it's better if I have a simple bash program to do it.

      


      4. 


    


    This is what the program should do :

    


      

    1. I use ubuntu, so the program should be written for linux system

      2. 


    2. I execute the program : ./videotrimmer.sh inputvideo.mp4 outputvideo.mp4

      3. 


    3. The program asks the starting time and the time it ends.

      4. 


    4. I enter the times.

      5. 


    5. And done !

      6. 


    


    Example :

    


      

    1. I want to trim the first 3 secs of a 10 secs video named videofile10secs.mp4. The file name of the trimmed video is videofile3secs.mp4

      2. 


    2. ./videotrimmer.sh videofile10secs.mp4 videofile3secs.mp4

      3. 


    3. The program asks the times. I input "00:00:00" and "00:00:03"

      4. 


    4. I press the return key.

      5. 


    5. Done. I should have a new file videofile3secs.mp4.

      6. 


    


    How to write that ? Any help will be highly appreciated.
