  • ffmpeg version 2.6.8 : Stream specifier ':a' in filtergraph description matches no streams

    16 décembre 2020, par Ashitaka

    I am not getting why this isn't working.. I have tried to get the video streams with [0:v]/[0:1]/[0:v:0] & the audio streams with [0:a]/[0:0]/[0:0:0].
nothing worked.

    


    Explaining the inputs :

    


    1.1st input stream is a video that can be of varying resolution on which the filter adds a padding on to make it 600:480.

    


    2.2nd input is an overlay png which is already at 5:4 ratio.. just making it 600:480 before it gets overlaid in the filter.

    


    3.3rd & 4th ones are also videos which I don't care if they get stretched.. n they are getting stretched to 600:480.

    


    4.so finally there are 3 streams 1 overlaid video 2 stretched videos which needs to be concatenated.

    


    here's the command :

    


    ffmpeg 
-i '/home/vidinflux/public_html/assets/temp/2018020116464612/2018020116464612.mp4'

  • Using FFmpeg in .net ?

    15 juillet 2016, par daniel

    So I know its a fairly big challenge but I want to write a basic movie player/converter in c# using the FFmpeg library. However, the first obstacle I need to overcome is wrapping the FFmpeg library in c#. I’ve downloaded ffmpeg but couldn’t compile it on Windows, so I downloaded a precompiled version for me. Ok awesome. Then I started looking for C# wrappers.

    I have looked around and have found a few wrappers such as SharpFFmpeg (http://sourceforge.net/projects/sharpffmpeg/) and ffmpeg-sharp (http://code.google.com/p/ffmpeg-sharp/). First of all, I wanted to use ffmpeg-sharp as its LGPL and SharpFFmpeg is GPL. However, it had quite a few compile errors. Turns out it was written for the mono compiler, I tried compiling it with mono but couldn’t figure out how. I then started to manually fix the compiler errors myself, but came across a few scary ones and thought I’d better leave those alone. So I gave up on ffmpeg-sharp.

    Then I looked at SharpFFmpeg and it looks like what I want, all the functions P/Invoked for me. However its GPL ? Both the AVCodec.cs and AVFormat.cs files look like ports of avcodec.c and avformat.c which I reckon I could port myself ? Then not have to worry about licencing.

    But I want to get this right before I go ahead and start coding. Should I :

    1. Write my own C++ library for interacting with ffmpeg, then have my C# program talk to the C++ library in order to play/convert videos etc.

    OR

    1. Port avcodec.h and avformat.h (is that all i need ?) to c# by using a whole lot of DllImports and write it entirely in C# ?

    First of all consider that I’m not great at C++ as I rarely use it but I know enough to get around. The reason I’m thinking #1 might be the better option is that most FFmpeg tutorials are in C++ and I’d also have more control over memory management than if I was to do it in c#.

    What do you think ?
    Also would you happen to have any useful links (perhaps a tutorial) for using FFmpeg ?
