  • Storing high quality video stream (from IP Action Camera) continuously to a Storage Device and issues around Write-Speed bottlenecks

    21 mai 2017, par Aldo

    I am looking to get an Action Camera (Eken H8R, or a GoPro) for a project. Let me explain the scenario I have :

    I will obtain a live stream from the camera on to a Raspberry Pi (over WiFi) as shown here. Next, I want to continuously segment this live stream into 10-15 minute video clips and store them in an external Hard Drive (which is connected to the RPi). I am considering this thread, and the avconvcommand mentioned in the answer by Alexander.

    Now, my concern is write-speed limitations. The video stream would probably have a high bitrate, and might be 4k30fps, in which case file sizes would be huge. Would write speed to disk be a bottleneck ? If so, how will the Pi maintain a buffer to achieve this ? Could I run out of space as the memory stick on the Pi would only be around 8 gigs ? If so, what’s a better alternative ? Please correct me if I’m wrong on these as I’m only a beginner.

  • downloading and concatenating parts of videos from youtube

    17 octobre 2018, par amit

    I’m trying to create a video quiz, that will contain small parts of other videos, concatenated together (with the purpose, that people will identify from where these short snips are taken from).

    For this purpose I created a file that contain the URL of the video, the starting time of the "snip", and its length. for example :

    https://www.youtube.com/watch?v=5-j6LLkpQYY   00:00   01:00
    
https://www.youtube.com/watch?v=b-DqO_D1g1g   14:44   01:20
    
https://www.youtube.com/watch?v=DPAgWKseVhg   12:53   01:00

    Meaning that the first part should take the video from the first URL from its beginning and last for a minute, the second part should be taken from the second URL starting from 14:44 (minutes:seconds) and last one minute and 20 seconds and so forth.

    Then all these parts should be concatenated to a single video.

    I’m trying to write a script (I use ubuntu and fluent in several scripting languages) that does that, and I tried to use youtube-dl command line package and ffmpeg, but I couldn’t find the right options to achieve what I need.

    Any suggestions will be appreciated.
