  • 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.

  • Any way to speed up this side by side video merging FFMPEG command ?

    25 mai 2022, par John

    I am taking two mp4 videos and putting them side by side with a slight zoom so it looks better. Right now the best I get is speed at 7x which will still take a long time for an hour-long MP4 video (not to mention the size with ultrafast). Is there anything else I can do ? I thought maybe scaling and cropping first, then combining with copying video and audio but that doesn't appear to be faster.

    


    ffmpeg -y -i input1.mp4 -i input2.mp4 -filter_complex "[0]scale=-2:720,crop=640:720[v0];[1]scale=-2:720,crop=640:720[v1];[v0][v1]hstack;[0:a][1:a]amerge[a]"  -strict experimental -map 0:v -map '[a]' -ac 1 -preset ultrafast -vsync 0 output.mp4
