  • can't decode RTMP stream from adobe FMS

    25 juillet 2013, par Mike Versteeg

    I have written code to decode RTMP streams but ran into a problem decoding a stream from FMS. Same stream from Wowza server works fine, but when using Adobe FMS I
    keep getting the same error (note it works fine in a flash player).

    I can confirm the problem using ffmpeg.exe, here's the output of the latest git, anyone have an idea ?

  • Why audio element currentTime on ffmpeg encoded mp3 file in Chrome browser does not work

    26 juillet 2013, par Peter

    I have an HTML5 audio element :

    <audio preload="auto">
    
    <source src="./Sound/recording.mp3" type="audio/mpeg">
    
</source></audio>

    and I need to be able to play last 4 seconds from mp3 recording. My javaScript is :

    audio.currentTime = audio.duration-4;
    
audio.play();

    Works ok in IE10 and Firefox, but Chrome starts playing from a wrong place. The difference between reported audio.currentTime and actual playback position is about 20s. The recording.mp3 is created with ffmpeg :

    ffmpeg -i recording.wav -ab 32k recording.mp3

    It works, when I strip the ID3v2 header from the recording.mp3 (deleting the first couple bytes in the file before the audio data).

    It also works when I compress to ogg. Can somebody point me to the right direction (ffmpeg switches, audio element attributes or whatever) to get it work also in chrome ?

    Thanks in advance
