  • RTMP streaming without flash and low latency

    4 juin 2020, par Ruben Sanchez Castellano

    I have a server that currently streams out RTMP media and I need to play it with minimum delay (2-3 seconds).
Now I'm using CRTMPServer to consume the stream but, since there is no RTMP player without flash dependency, this solutions does not work for me because I need to play it embedded into a web page.

    



    At this point, I tried Nimble Streamer but I only could consume HLS, DASH and SLDP. HLS and DASH has 10 second delay so I discard these approaches.
SLDP has low latency but is a closed protocol and there is only one player (closed but freeware).

    



    On the other hand, there is RTSP but there are no HTML5 players for it. But I couldn't consume RTSP streams from Nimble neither.

    



    Any other ideas ?

    


  • ffmpeg fast seek large MP4 over HTTP

    28 juillet 2024, par Gmanicus

    I'm attempting to download snapshots from a video provided by the U.S House of Representatives :

    


    https://houseliveprod-f9h4cpb9dyb8gegg.a01.azurefd.net/east/2024-04-11T08-55-12_Download/video_3000000_1.mp4


    


    I am using fluent-ffmpeg in Node to execute this command :

    


    ffmpeg('https://houseliveprod-f9h4cpb9dyb8gegg.a01.azurefd.net/east/2024-04-11T08-55-12_Download/video_3000000_1.mp4')
  .inputOption(`-ss 03:33:33`)
  .outputOptions([
     '-vframes 1'
  ])
  .output('test.png')

// Effectively:
// ffmpeg -ss 03:33:33 -i  -y -vframes 1 test.png


    


    My intention is to fast-seek to the desired timestamp and take a snapshot over HTTP. However, when doing so, the performance is not great. A snapshot takes about 10s per 3hrs of video and seems to increase fairly linearly at that rate.

    


    However, when using ffmpeg on the same video locally, it's super fast ! Sub-500ms regardless of the desired timestamp.

    


    Is there some magic that could be done via ffmpeg options or perhaps some sort of technique with manual requests to get a snapshot at the desired segment of video more efficiently ?
