  • Audio HLS with metadata on Mac from directory of mp3 files ?

    2 février 2017, par eagspoo

    I’m trying to create HLS output (m3u8 file + many .ts files) from a list of mp3 files where the mp3 id3 metadata is preserved in the HLS output.

    I’ve been trying ffmpeg like this :

    ffmpeg -f concat -i list.txt -hls_init_time 2 -hls_time 2 out.m3u8

    where list.txt contains :

    file 01.mp3
    file 02.mp3
    file 03.mp3
    file 04.mp3
    file 05.mp3
    file 06.mp3
    file 07.mp3
    file 08.mp3
    file 09.mp3
    file 10.mp3

    The result is a single out.m3u8 file and a single very large out0.ts file. I was expecting about 1500 ts files and an m3u8 file that contains the last 5 ts files.

    I’m completely new to ffmpeg and honestly I don’t want to learn it in depth right now.

    Does anyone know how to do this either with ffmpeg or otherwise ?

  • ffmpeg mkv to mp4 including subtitles

    1er février 2017, par user3677559

    Want to convert mkv files to mp4 (h264, mp3 and subtitles). I checked the video files with ffprobe. For the output

    Stream #0:2(ger) : Subtitle : dvb_subtitle (default)

    The subtitles are included in the converted video with following ffmpeg command.

    ffmpeg -i movie.mkv -c:v libx264 -c:a libmp3lame  -b:a 320k -c:s dvd_subtitle  converted.mp4

    But for the output :

    Stream #0:3(ger) : Subtitle : subrip (default)

    The command isn’t working. There is no error message and the resulting video includes a subtitle stream, but no subtitles are showed. I tried also with the subtitle encoding mov_text and copy, but no luck. Following the output from console :

    OFFICIAL EDIT :

    I thank you so much for your help but I am still encountering problems.

    My ffserver.conf file is like this :

    # Port on which the server is listening. You must select a different
    # port from your standard HTTP web server if it is running on the same
    # computer.

    # Address on which the server is bound. Only useful if you have
    # several network interfaces.
    HTTPBindAddress 0.0.0.0

    # Number of simultaneous HTTP connections that can be handled. It has
    # to be defined *before* the MaxClients parameter, since it defines the
    # MaxClients maximum limit.
    MaxHTTPConnections 2000

    # Number of simultaneous requests that can be handled. Since FFServer
    # is very fast, it is more likely that you will want to leave this high
    # and use MaxBandwidth, below.
    MaxClients 1000

    # This the maximum amount of kbit/sec that you are prepared to
    # consume when streaming to clients.

    # You can repeat the ACL allow/deny as often as you like. It is on a per
    # stream basis. The first match defines the action. If there are no matches,
    # then the default is the inverse of the last ACL statement.
    #
    # Thus 'ACL allow localhost' only allows access from localhost.

    #
    # An SDP file is automatically generated by ffserver by adding the

    # http://localhost:8090/test1-sdp.sdp). You should usually give this
    # file to your player to play the stream.

    I started my server and executed :

    ffserver -d -f /usr/share/doc/ffmpeg-2.6.8/ffserver.conf

    No error message and everything looks fine.

    After that I execute this (in your answer, I think you forgot the port number) :

    ffmpeg -i "rtsp://200.180.90.95:554/onvif1" -r 25 -s 640x480 -c:v libx264 -flags +global_header -f flv "http://45.79.207.38:8090/feed1.ffm"
