  • RN CameraRoll gives uri as ph : //

    30 septembre 2020, par Roman Adigezalov

    Faced such a problem, I get a video using CameraRoll in order to later transfer this file to FFMpeg, but the problem arises in the fact that the path to the file is on ios using the ph protocol. How to be in this situation ? How do I get real access to the file ?

    


  • How should one start with ffmpeg's API ?

    20 mai 2018, par JoeDough

    I’d like to make a real time streaming program that takes input from a webcamera, ffmpeg looks like a good library for encoding a stream of images but there is no documentation or community tutorials (there is just a doxygen API reference).Where should I start if there’s no official documentation ?

  • How to convert VP8 track with different frame resolution to h264

    13 septembre 2016, par Nikita

    I have a .webm file with VP8 track, recorded from WebRTC stream by external service (TokBox Archiving). The stream is adaptive, so each frame in track could have different resolution. Most players (in webkit browsers) use video resolution from track description (which is always 640x480) and scale frames to this resolution. Firefox and VLC player uses real frame resolution, changing video resolution respectively.

    I want to achieve 2 goals :

    1. play this video in Internet Explorer 9+ without additional plugin installation.
    2. change frames resolution to one fixed resolution, so the video will look identically in different browsers.

    So, my plan is :

    • extract frames from source webm file to images with real frame resolution (e.g. PNG or BMP) (how could I do that ?)
    • find max width and max height of images
    • add black padding to images, so smaller frames will be in the center of a new frame (of size MAX_WIDHTxMAX_HEIGHT)
    • combine images to h264 track using ffmpeg

    Is all correct ? How can I achieve this ? Can this algorithm be optimized some way ?

    I tried ffmpeg to extract images, but it does not parse real frame resolution, using resolution from track header.
    I think some libwebm functions can help me (to parse frame headers and extract images). Maybe someone has some code snippets to do this ?
