  • Trying to flip a movie with ffmpeg hflip vplip fails

    7 août 2019, par S.T

    I am trying to flip a movie with
    hflip
    and
    vflip

    and it’s creating an empty movie in some of the movies i converted (some of them succeeded).

    i tried to convert all kind of movies and i don’t know if this is the reason but maybe it related if the movie is in landscape or portrait ?
    This is the command i use :

    ffmpeg -i INPUT -vf hflip -c:a copy OUTPUT

    expected to see the movie flipped as i wanted in my command.

    Thanks.

  • How to estimate bandwidth / speed requirements for real-time streaming video ?

    19 juin 2016, par Vivek Seth

    For a project I’m working on, I’m trying to stream video to an iPhone through its headphone jack. My estimated bitrate is about 200kbps (If i’m wrong about this, please ignore that).

    I’d like to squeeze as much performance out of this bitrate as possible and sound is not important for me, only video. My understanding is that to stream a a real-time video I will need to encode it with some codec on-the-fly and send compressed frames to the iPhone for it to decode and render. Based on my research, it seems that H.265 is one of the most space efficient codecs available so i’m considering using that.

    Assuming my basic understanding of live streaming is correct, how would I estimate the FPS I could achieve for a given resolution using the H.265 codec ?

    The best solution I can think of it to take a video file, encode it with H.265 and trim it to 1 minute of length to see how large the file is. The issue I see with this approach is that I think my calculations would include some overhead from the video container format (AVI, MKV, etc) and from the audio channels that I don’t care about.
