  • HTTP Live Streaming - Byte-range in m3u8 file

    3 avril 2019, par Phantom

    I'm trying to use ffmpeg to get an m3u8 file with byteranges(#EXT-X-BYTERANGE), but with several segments (.TS).

    the unique and functional solution is used:

    -hls_flags single_file

    but I do not want only one file, but several with approximate 20MB

    Does anyone have any ideas?

    my main idea was to split the mp4 file into relative sizes, and use single_file -hls_flags, to create the m3u8 file with byteranges and then form a new m3u8 file with all parts...

  • how to fade in and out background music when speech play and fade out audio at the end and mix them together using ffmpeg

    3 avril 2019, par Harshil Dholakiya

    I am using below command in my project to mix background music with my speech audio and background music slow down volume level when speech play:

    ffmpeg -y -i speech.mp3 -stream_loop -1 -i music.mp3 -filter_complex "[0:a]asplit=2[sc][mix];[1:a][sc]sidechaincompress=threshold=0.01:ratio=5[bg];[mix][bg]amix=inputs=2:duration=first:dropout_transition=0[final]" -map [final] finalAudio.mp3

    i want to add this two filter to audio:

    1) Fade-in effect to background music for 1.5 sec when speech arrive and fade-out effect when speech is finish for 1.5 sec. speech.mp3 has more than one speech and silence in between speech.

    2) Fade out effect at the end of audio for 1.5 sec.

    can anyone help me to achieve both of above filter using ffmpeg with my above command?

    How to generate video thumbnail in nodejs, I have been following these tutorials to install ffmpeg https://www.wikihow.com/Install-FFmpeg-on-Windows

    Here is the code :

     var Name = req.file['filename'];
        Files[Name] = { //Create a new Entry in The Files Variable
            FileSize: req.file['size'],
            Data: "",
            Downloaded: 0
        }
        fs.open("Temp/" + Name, 'a', 0755, function(err, fd) {
            var inp = fs.createReadStream("Temp/" + Name);
            var out = fs.createWriteStream("Video/" + Name);
            exec("ffmpeg -i Video/" + Name + " -ss 01:30 -r 1 -an -vframes 1 -f mjpeg Video/" + Name + ".jpg", function(err, dd) {
                if (err) {
                    console.log(err)
                }

  • insert audio into another audio file (eg a censor bleep)

    3 avril 2019, par Redzarf

    I need to insert a short beep into another audio file (similar to a censorship bleep) using linux and/or php.

    I'm thinking there should be some way to do it with ffmpeg (with some combination of -t, concat, map, async, adelay, itsoffset?) or avconv or mkvmerge - but haven't found anyone doing this. Maybe I need to do it in 2 stages somehow?

    For example if I have a 60 second mp3 and want to beep out 2 seconds at 2 places the desired result would be:

    0:00-0:15  from original
0:15-0:17  beep (overwrites the 2 secs of original)
0:17-0:40  from original
0:40-0:42  beep
0:42-0:60  from original

    I have a 2 second beep.mp3, but can use something else instead like -i "sine=frequency=1000:duration=2"

  • ffmpeg streaming video not in sync

    3 avril 2019, par Tenaciousd93

    I have a problem saving a streaming with ffmpeg. The problem is that video is not in sync with audio.

    The video comes 2-3 seconds before the audio.

    I try by removing and editing options but nothing change, I make some research too and I try all solution described in this great answer posted here, but it didn't work for me.

    I tried to download a chunk from playlist and I've got a .ts file with audio/video in sync.

    If I play the streaming with VLC player I can hear the audio without video for some seconds, then the video appear and is in sync with audio.

    ffplay play the same streaming correctly too: seems like there is the time information inside audio and video codec and can be played correctly in sync.

    How can I ask ffmpeg to take audio and video in sync?

    If you need ffmpeg or ffplay outputs I will post them.

    Edit: as requested, I report the full ffmpeg output of a simple command to save stream output to file:

    $ ffmpeg -i http://la7livehls-lh.akamaihd.net/i/livebkup_1@372883/master.m3u8?hdnts=st=1554271074~exp=1554271524~acl=/*~hmac=14df2434241f7fd52f5a6012094367180f8567a1a733f7ef9eeef3dc7b46ebb2 -c copy out.mp4
