  • RTSP to RTMP in iOS as Transcoding

    15 mars 2019, par Naman Sheth

    I am getting live feed from some IP camera as an RTSP url and then i want to convert it to RTMP.

    Here is two aspects that we have to implement

    1. What we convert from RTSP to RTMP is transcoding.
    2. I have my iPad/iPhone Camera that user can switch and add live feed to RTMP url at this point I want to stop RTSP feed. i.e. Encoding

    This all scenario want to do with FFMPEG

    I have searched on this url but not able to figure out in iOS

    ffmpeg -i "[your rtsp link]" -f flv -r -s -an "[Your rtmp link]"

    RTSP to RTMP streaming

    Thanks in Advance !

  • Convert videos from .264 to .265 (HEVC) with ffmpeg [closed]

    11 août 2024, par John Terragnoli

    I see that there are a few questions on this subject but I am still getting errors. All I want to do is convert videos in my library to HEVC so they take up less space.
    
I've tried this :

    



    ffmpeg -i input.mp4 -c:v libx265 output.mp4


    



    ffmpeg seems to take a long time and the output seems to be about the right size. The video will play with VLC but the icon is weird and when I try to open it with QuickTime, I get the error : 'The document “output.mov” could not be opened. The file isn’t compatible with QuickTime Player.'

    



    I don't want to change any of the fancy settings. I just want the files to take up less space and with minimal or no quality loss.

    



    Thanks !

    



    EDIT : 
Having trouble keeping the time stamp that I put into the videos.
    
Originally I was using exiftool in terminal. But, sometimes that doesn’t work with videos, so I would airdrop them to my iPhone, use an app called Metapho to change the dates, and then airdrop them back. Exiftool was create but sometimes I just wouldn’t work. It would change the date to something like 1109212 Aug 2nd. Weird. Bottom line is that when I do these conversions, I really don’t want lose the time stamps in them.
