    11 mai 2020, par user1503606

00:00:06,840 --> 00:00:10,320
once long ago in the deep blue below

2
00:00:12,360 --> 00:00:14,370
Don't be silly, Gran Mother

3
00:00:14,870 --> 00:00:16,700
Everybody knows there's no such thing as

4
00:00:16,700 --> 00:00:17,200
Mermaids

5
00:00:17,620 --> 00:00:21,570
You wouldn't say that if you has meet one. You've meet a Mermaid

6
00:00:24,250 --> 00:00:25,180
This just came in

7
00:00:25,480 --> 00:00:26,630
I wanted to take priority

8
00:00:27,180 --> 00:00:28,500
And we followed stories like this before

9
00:00:28,640 --> 00:00:31,620
Would witches working mummies. No not like this

10
00:00:31,630 --> 00:00:33,190
Hundreds of people are testifying

11
00:00:33,370 --> 00:00:34,600
Welcome to Mississippi

12
00:00:42,390 --> 00:00:47,270
There's a powerful magic in you the spirit of the ocean

13
00:00:47,690 --> 00:00:53,940
Let me introduce you to your dreams, The Little Mermaid, off the Mississippi

14
00:01:01,880 --> 00:01:03,580
She was so beautiful

15
00:01:04,040 --> 00:01:05,270
And I know she was real

16
00:01:07,850 --> 00:01:08,550
I'm skeptical

17
00:01:13,460 --> 00:01:14,410
You shouldn't be here

18
00:01:17,560 --> 00:01:24,130
Mermaids do not exist

19
00:01:31,420 --> 00:01:34,300
Look isn't it beautiful? Sorry I have to go.

20
00:01:35,340 --> 00:01:48,570
Elizabeth, How can this be? It's Lock he knows i'm here he summoned me.

21
00:01:48,570 --> 00:01:50,570
We have to save here.

22
00:02:03,570 --> 00:02:05,570
Here soul is mine

23
00:02:05,570 --> 00:02:06,570
Take it

24
00:02:10,570 --> 00:02:12,570
It's the only way

25
00:02:15,000 --> 00:02:17,570
I believe

26
00:02:23,000 --> 00:02:25,570
Mississippi has always been magic

27
00:02:36,000 --> 00:02:38,000
Elizabeth please


    



    If I use AWS Media convert to add this to my playlist it outputs the following.

    



    #EXTM3U

#EXT-X-MEDIA-SEQUENCE:1
#EXT-X-PLAYLIST-TYPE:VOD

    And the WebVTT file looks like this.

    I am trying to replicate this with FFMpeg. I have tried the following command.

    



    ffmpeg -i little-mermaid.mov -i little-mermaid.srt -c copy -c:s webvtt -start_number 0 -hls_time 10000 -f hls mermaid/Eng/master.m3u8


    



    This creates a WebVTT file but it is completely wrong and out of sync. See below.

    



    All the times have changed and it's removed the first two digits from each section.

    I am trying to decide if it just makes sense to convert the .srt to WebVTT and use that file without encoding with FFMPEG just create a .m3u8 file with -hls_flag single_file that points to it but not sure what implementation this might cause.

    



    Can anyone suggest how I could do this or where I might be going wrong ?

    



    Here is the video file I am using if anyone wants to run the FFMPEG command above to test.

    Thanks

    


  • Can an executable be run as a part of a blob-triggered Azure Function ?

    24 décembre 2018, par Dhruv Kapoor

    I know executables are suitable for timer triggers, but since the timer trigger doesn’t require parallel access to the executable, I wasn’t sure if it works for blob triggers. Let’s say I have 10 messages in my queue, will the Azure runtime cause a lock on the executable ? Or will it manage just fine with 10 parallel instances ? The context to this question is a wrapper library (NReco) I’m using around the FFMPeg utility. The binaries for FFMPeg are required during the exeution of my Azure function.

  • How to start live streaming on Mac using FFMPEG ?

    22 mars 2018, par Alexandra Chis

    I am working on a MAC OS X Lion 10.7.5.

    How to properly install FFMPEG ?

    What I did :

    ruby -e "$(curl -fsSL https://raw.github.com/mxcl/homebrew/go)"
    
brew install ffmpeg --with-fdk-aac --with-ffplay --with-freetype --with-frei0r --with-libass --with-libvo-aacenc --with-libvorbis --with-libvpx --with-opencore-amr --with-openjpeg --with-opus --with-rtmpdump --with-schroedinger --with-speex --with-theora --with-tools

    and even (I think this should work, but it doesn’t)

    brew install ffmpeg

    Nothing works...I can’t list the inputs, I can’t start the streaming from the USB camera, I can’t do anything.

    ffmpeg -f video4linux2 -s 320x240 -i video="USB cam":audio="USB mic" -f oss -acodec libvorbis -vcodec libvpx -f webm http://localhost:1234/streaming

    The errors I get look like this :

    unknown input format 'video4linux'

    and the same happens for alsa, openal, vfwcap etc.

    So did anyone try live streaming with FFMPEG from MAC ?
    How to install FFMPEG so that is supports video4linux2 or v4l2 or any input format at all ? How to list the devices (USB webcams or integrated webcams) ?
