  • Video frames with timestamp or export frame name and timestamp to excel file

    20 avril 2022, par Melodic_Knee

    I need to break a video into frames (60fps) and frame name must be in the fashion of %d_hh-mm-ss.ms.png, Or, any solution that gives frame name, and the time in excel file will work

    


    Note : - time here must be the time at which the frame appeared in the video

    


  • C# library for audio resampling that has the same abilities as FFmpeg

    21 avril 2013, par Designation

    I have to use a pure C# solution for resampling audio, which can produce me the exact same results as FFmpeg's audio sampling can.

    FFmpeg first builds some kind of polyphase filter bank, and then uses that for the sampling process (sorry for the vague phrasing, but I'm not too familiar with this topic). According to this brief documentation, the initialization can be customized this way :

    AVResampleContext* av_resample_init(
    
    int     out_rate,
    
    int     in_rate,
    
    int     filter_length,
    
    int     log2_phase_count,
    
    int     linear,
    
    double  cutoff   
    
    )

    The parameters are :

    • out_rate : output sample rate
    • in_rate : input sample rate
    • filter_length : length of each FIR filter in the filterbank relative to the cutoff freq
    • log2_phase_count : log2 of the number of entries in the polyphase filterbank
    • linear : if 1 then the used FIR filter will be linearly interpolated between the 2 closest, if 0 the closest will be used
    • cutoff : cutoff frequency, 1.0 corresponds to half the output sampling rate

    I'd need to use a C# library that is configurable in the same depth. I've been trying to use NAudio (more specifically, its WaveFormatConversionStream class), but there, I could only set the input and output sample rates, so I didn't get the expected results.

    So, is there a C# lib that could resample with the same settings as FFmpeg can ? Or one that has almost all of these settings or similar ones ? Note : I need a C# solution, not a wrapper !

  • Can I extract an audio clip (a single word) from the video and insert at different points/timeline of same video using FFMPEG/libvlcsharp ?

    16 décembre 2019, par Siddharth

    I want to load a video that has a soundtrack, and I want it to take an audio clip of a single spoken word and I want the clip inserted at different points in the video. The output will be the new video. I also want to insert an image at certain points in the video (watermark).

    Can I do this using FFMPEG or libvlcsharp ?
