  • How to make HLS start from the begining

    15 septembre 2020, par Ariel Argañaraz

    I need some help with HLS streaming, I'm trying to create a playlist for streaming,

    



    I'm using ffmpeg to generate the files and the .m3u8 files. And for playing i'm using a web page with videojs player

    



    The idea is to simulate a live streaming using files already created.

    



    The problem is that in some version of iphone works and in another does not work.
The problem is that when I start play the video in the Safari browser of my phone it freezes for a while and then download and play the last segment.

    



    for example if the video is split in 4 differents .ts files.
It starts playing from the 4th .ts file and then stop.

    



    The problem is that I have 2 iphone mobile phone, one of them works perfectly but the other one not

    



    The not working cell phone is a iphone 6 (version 9.2.1)

    



    Here is my m3u8 file. Note that I'm using the #EXT-X-PLAYLIST-TYPE:EVENT and I remove the #EXT-X-ENDLIST from the botton. So it should be played as an live streaming.

    



    It works for another phones, it begins from the 0 second when I set the #EXT-X-START:TIME-OFFSET=0

    



    but in this version (9.2.1) the video freezes and then jumps to the last segment (webinar-3.ts) plays that segment and finally stop.

    



    #EXTM3U
#EXT-X-VERSION:4
#EXT-X-MEDIA-SEQUENCE:0
#EXT-X-ALLOW-CACHE:NO
#EXT-X-PLAYLIST-TYPE:EVENT
#EXT-X-START:TIME-OFFSET=0
#EXT-X-TARGETDURATION:6
#EXTINF:5.046444,
webinar-0.ts
#EXTINF:5,
webinar-1.ts
#EXTINF:5,
webinar-2.ts
#EXTINF:5,
webinar-3.ts


    



    Have anybody got an idea of what i'm doing wrong or how to get a m3u8 config that works for this iphone version ?

    


  • avformat/rtsp : Send mode=record instead of mode=receive in Transport header

    15 janvier 2024, par Paul Orlyk
    avformat/rtsp : Send mode=record instead of mode=receive in Transport header
    

    Fixes server compatibility issues with rtspclientsink GStreamer plugin.

    >From specification :
    RFC 7826 "Real-Time Streaming Protocol Version 2.0" (https://datatracker.ietf.org/doc/html/rfc7826), section 18.54 :
    mode : The mode parameter indicates the methods to be supported for
    this session. The currently defined valid value is "PLAY". If
    not provided, the default is "PLAY". The "RECORD" value was
    defined in RFC 2326 ; in this specification, it is unspecified
    but reserved. RECORD and other values may be specified in the
    future.
    RFC 2326 "Real Time Streaming Protocol (RTSP)" (https://datatracker.ietf.org/doc/html/rfc2326), section 12.39 :
    mode :
    The mode parameter indicates the methods to be supported for
    this session. Valid values are PLAY and RECORD. If not
    provided, the default is PLAY.

    mode=receive was always like this, from the initial commit 'a8ad6ffa rtsp : Add listen mode'.

    For comparison, Wowza was used to push RTSP stream to. Both GStreamer and FFmpeg had no issues.
    Here is the capture of Wowza responding to SETUP request :
