  • Playing RDT (Real Data Transport) through FFmpeg without SDP file

    24 février 2021, par William Seemann

    I'm doing some research into how Roku delivers their private listening stream. I believe the RTSP stream is delivered via RDT and I'm able to view the packets in Wireshark. I can't play the stream using FFmpeg despite it supporting RDT/RTSP because a SDP file is required. Is it possible to generate this SDP file or play the stream without one ?

    


  • How do you display closed caption format of HLS video stream from an m3u8 URL

    7 décembre 2016, par rynop

    I’m working on a Roku and TVOS app that is going to play HLS videos (VOD and live) as well as MP4. According to the Roku docs EIA-608 is supported on both and should also work on TVOS.

    My question is, given URL to the m3u8 how can I tell what specific format (EIA-608,WebVTT etc) of closed captioning is being used in each stream ?

    Contents of the main m3u8 (note 1st stream says no CC, but it really does have it) :

    #EXTM3U
    
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=380000,RESOLUTION=400x228,CODECS="avc1.66.30, mp4a.40.2",CLOSED-CAPTIONS=NONE
    
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_0_av.m3u8
    
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=750000,RESOLUTION=640x360,CODECS="avc1.77.30, mp4a.40.2",CLOSED-CAPTIONS=NONE
    
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_1_av.m3u8
    
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=1044000,RESOLUTION=1280x720,CODECS="avc1.64001f, mp4a.40.2",CLOSED-CAPTIONS=NONE
    
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_2_av.m3u8
    
#EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=2127000,RESOLUTION=1280x720,CODECS="avc1.64001f, mp4a.40.2",CLOSED-CAPTIONS=NONE
    
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/index_3_av.m3u8

    Contents of the 1st stream’s m3u8

    #EXTM3U
    
#EXT-X-TARGETDURATION:4
    
#EXT-X-ALLOW-CACHE:YES
    
#EXT-X-PLAYLIST-TYPE:VOD
    
#EXT-X-VERSION:3
    
#EXT-X-MEDIA-SEQUENCE:1
    
#EXTINF:4.000,
    
http://d.com/i/video/2426832/2426832_,350,640,1000,2000,.mp4.csmil/segment1_0_av.ts
    
...

    I can use ffprobe -hide_banner to show the 1st program’s stream has closed captioning. Ex :

    Duration: 00:02:36.76, start: 0.100511, bitrate: 0 kb/s
    
  Program 0
    
    Metadata:
    
      variant_bitrate : 380000
    
    Stream #0:0: Video: h264 (Constrained Baseline) ([27][0][0][0] / 0x001B), yuv420p, 400x228 [SAR 1:1 DAR 100:57], Closed Captions, 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc
    
    Metadata:
    
      variant_bitrate : 380000
    
    Stream #0:1: Audio: aac (LC) ([15][0][0][0] / 0x000F), 44100 Hz, mono, fltp, 48 kb/s
    
    Metadata:
    
      variant_bitrate : 380000

    However, as you can see, Program 0 > Stream 0 just says that is has Closed captions - it does not list the type/spec of closed captioning technology being used.

    How do I display the format of the Closed Captions ?
