ffmpeg incorrect duration when converting video to HLS

12 octobre 2016, par Julie Bsd

I’m facing an issue using ffmpeg to convert video, precisely mp4 video => Http Live Streaming (HLS)

Once converted to HLS, the .m3u8 file has a wrong duration (e.g : 20,1s instead of 20.00s), causing bugs when playing it with AVPlayer on iOS.
Playing the video with Safari cause the same issue.

Example :
1) Open Safari
2) Play this video that i’ve converted
3) Look at the download progression, stopped at 98% cause of wrong duration.

4) When you slide between 98% and 100%, the video player can crash.

EDIT 1 :

I’ve edited the command line

 ffmpeg -i  video.mp4 \

 -codec copy \

 -acodec copy \

 -map 0 -f ssegment -g 60 -sc_threshold 0 \

 -segment_list playlist.m3u8 \

 -segment_list_flags +live \

 -segment_time 2 media%05d.ts \

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 ?
