  • How to re-multiplex Multiple Program Transport Stream (MPTS) files into a single TS ?

    22 avril 2015, par rantsh

    I have multiple MPTS files recorded from satellite receivers, I need to cherry pick programs/services/PIDS from each file re-multiplex them into a single MPTS file. Optionally I might be able to get away with taking all the services from every file and adding them to the final MPTS (In case anyone knows about a multiplexer that wouldn’t allow me to cherry pick programs)

    Does anybody know how to do this with open source or free software (like VLC or ffmpeg for example) under either windows or linux ?

  • FFmpeg converting image sequence to video results in blank video [closed]

    11 septembre 2016, par Brandon Durham

    I’ve got a series of 361 .png files that I’m trying to convert to video, and for whatever reason the resulting video is just black. Here is the FFmpeg code I’m using :

    ffmpeg -f image2 -i "FeatureTour_%05d.png" -r 30 -vcodec libx264 -b:v 9600k "FeatureTour.mp4"

    The files are formatted correctly (FeatureTour_00001.png) and no errors are thrown. It just results in a 160kb mp4 files that’s black.

    Any idea what I’m doing wrong ?

    EDIT

    Here is my output after using the above code :

    28 novembre 2012, par shampoo

    i am testing clip bucket on a windows xp system , clip bucket (open source video share) uses ffmpeg to convert videos, the final command clip bucket executes is (i changed it a little to make it compatible with the current ffmpeg) :

    D:\ffmpeg-snapshot-git\ffmpeg\ffmpeg.exe -i C:
    \wamp\www\chclip/files/conversion_queue/1352973741c353c.mp4 -f flv -vcodec libx2
    64 -pre normal -r 25 -s 426x240 -aspect 1.775 -vf "pad=10:20:30:40:yellow"  -ac
    odec libfaac -ab 128000 -ar 22050 C:\wamp\www\chclip/files/videos/13540939451e18
