  • OpenCV won't open the same videofile as opened before

    12 novembre 2013, par OpenMinded

    I have a problem to load a videofile. I am using Visual Studio 2010 and OpenCV 2.4.6.

    Sometimes it loads video properly and sometimes it won't, although it is the same file and the same code (Nothing has changed). So basically, one day it works and the next day does not. I noticed some strange behavior BEFORE.

    When I run the code I get Unhandled exception

    enter image description here

    and then No source available

    enter image description here

    A few weeks ago I wasn't able to open a video in one of my project. The problem was that if I opened a project from pinned Start menu than the video couldn't be loaded.

    enter image description here

    BUT when I opened a solution right from a directory than video was loaded properly. I couldn't believe so I tried this more times.

    However, in either case it does not work this time.

    ALso, I tried to run Visual Studio as admin. Nothing.

    What could be a problem here ?

  • avformat/mpegts : initialize max_packet_size when sub-demuxer

    5 février 2022, par Gyan Doshi
    avformat/mpegts : initialize max_packet_size when sub-demuxer

    bca30570d2 added a user option to set max_packet_size replacing
    
a hardcoded value. This had a side-effect of leaving the field
    
set to 0 when packet demuxing is carried out from another demuxer
    
using avpriv functions, which could lead to demux failure.
    

    Hardcoded max_packet_size inside avpriv_mpegts_parse_open to
    
2048000 to avoid this. Value chosen to be 10x that of default value
    
to accommodate large payloads.

    I would like to transform them into one 5.1 audio channel

    I try this line of code :

    D:\test-remapping>ffmpeg -i "MelleParadis_PART1_CONSTANTE.mov" -c copy -c:a ac3 -map 0 mlle5.1.mov

    the console replies "NOT ENOUGH SPACE" and stop...
    of course there's still some space in my hard drive...
    How could I map all the 6 mono streams into 5.1 ?
    thanks in advance.
