  • FFmpeg libx264 iOS

    8 octobre 2013, par user441918

    I have to stream a RTSP video from IP camera in iOS. I found that I can use FFmpeg to stream the RTSP and it seems working. When I reviewed the legal terms of FFmpeg, it says "Make sure your program is not using any GPL libraries (notably libx264)". Does it mean, I cannot use libx264 library in iOS application or do I have to compile the FFmpeg library with "disable-gpl" option ?

    If FFmpeg with libx264 cannot be used in iOS, is there any other alternative library available ?

  • Create thumb of video

    10 novembre 2022, par Emre8

    I have multiple long-video recordings. In this video, I want to create a thumb but it takes a lot of CPU and time and the most critical problem is that I can't get total thumbs. During the first 1.5 hours the thumb is formed. Unfortunately, there is no sequel.

    


    How can I create a full thumb image in terms of performance and video length ?

    


    ffmpeg -i input1080p.mp4 -filter_complex "select='not(mod(n,10))',scale=150:-1,tile=layout=100x5000:overlap=1" -vframes 1 -q:v 2 oneThumbFile.jpg'


    


  • x264 Downsides of a high CRF (22) intermediary codec between conversions instead of lossless

    18 décembre 2019, par bobtheencoder

    I have a huge collection of video files that are in the range of CRF 16-20 taking up TB’s of space. The only need I have for these originals is that I have to encode them from time to time but the CRF of these final encodes is very low (CRF 26-28).

    I understand that a lossy to lossy converstion ALWAYS results in some quality loss but my question is what if the intermediate file is almost visually lossless compared to the final output.

    So to sum up, what quality difference should I expect from the following routes ?

    CRF 18 (original) -----> CRF 28 (final)
    
CRF 18 (original) -----> CRF 22 (long-term storage) -----> Lossy  CRF 28 (final)
