  • FFMPEG live transcoder aac_latm audio crash

    15 mars 2013, par user1716057

    i am trying to use ffmpeg as a live transcoder to transcode tv channels from udp input to rtmp output to a wowza server.

    i have 2 kinds of input channels in 1st kind the input audio is mp2 and in the second kind the input audio is acc_latm.

    my problem is when i transcode the mp2 channels everything is fine but when i try to transcode the aac channel the audio is muted after few hours. but the video is fine.

    the output codecs are : libx264 for video and faac or fdk-aac for audio output
    i tried both aac encoders but it did not change.

    i think it is the ffmpeg aac decoder's problem. but i cannot fix this.

    i need a way to detect the problem online and restart the ffmpeg. or change the ffmpeg decoder codec.

    please help.
    thanks.

  • Live streaming using FFMPEG [migrated]

    15 mars 2013, par Luuk D. Jansen

    This is rather a simple question, but I cannot find the answer.
    I need to stream from a capture device to a server, and then have FFMPEG on the server re-code the stream suitable for HLS.

    But how do I do this ?
    I looked at Flash Media Live Encoder and VLC and ffserver but cannot really get my handle on how this should work. Basically it just seems to me I need a program to sent to a server, which accepts the stream (and maybe some user authentication) and then makes the stream available for use. I already have a system that takes files and encodes them for HLS, so then I can just as input parameter point to this application on the local server to take the stream and start encoding.

    edit : it is really only the step to accept e.g. a rtmp connection and make that available to FFMPEG on the same server. I was hoping that e.g. ffserver could do that, but I don't think so.

  • FFMPEG : Queue input is backward in time & invalid, clipping issue [on hold]

    22 octobre 2013, par Sai

    I am using FFMPEG to convert the following video from wmv to flv and getting errors.

    Command is

    ffmpeg -i Sample.wmv  -qscale 0 -s 472x314 -ar 22050 -ac 1 -ab 96k  -g 5 Sample.flv

    I am getting these errors

    [libmp3lame @ 000000000030b640] Queue input is backward in time
    
[flv @ 00000000003e6b20] st:0 PTS: 560 DTS: 560 < 577 invalid, clipping

    Although the file is getting converted from the command line. Conversion is being interrupted after integrating with my application.

    And the video size is 300MB

    Any idea why these errors were coming ?
