  • Need help transcoding Red5 RTMP stream to MPEG2-TS

    5 février 2014, par reyniraron

    Me and my friend are going to make live shows and for that purpose I have set up a Red5 server on my old 2006 Intel Core Duo Mac mini running Mac OS X Snow Leopard Server 10.6.8.

    I use Flash Media Live Encoder to broadcast to Red5's oflaDemo application and the stream works great, except for the fact that I want the stream to work with iOS.
    I am developing an app for it, but I still need to convert my stream to Apple's HTTP Live Streaming protocol for it to work.
    Can anybody help me convert the RTMP stream to MPEG2-TS, because that's the format that mediastreamsegmenter supports ? I already have Apple's HTTP Live Streaming Tools installed on the server, so the segmenter's not a problem.

    FFmpeg doesn't work, at least not with the code I found here. With it a always get an "Operation not permitted" error. Xuggler doesn't work, not even with a Linux box.
    Can anybody please help me ? I'd really, really appreciate it.

  • Generating 64kbps audio-only mpegts for HTTP Live segmenter to meet 64kbps audio only requirement

    14 juin 2013, par Pobre

    I am trying to convert our mp4 files into mpeg-ts and segment it into .ts files for my iphone app to play. I am using Carson McDonalds's HTTP-Live-Video-Stream-Segmenter-and-Distributor to do that.

    I got his stuff complied and working correctly. I am currently trying to meet Apple's requirement where I need to provide a baseline 64 kbps audio only stream to my m3u8 playlist.
    Carson doesn't seem to have a profile for that.

    I need to be able to generate 64kbps audio-only stream from mp4, and turn that into mpeg-ts for the segmenter into ts. I am trying to find the right ffmpeg command that will validate without problem using Apple's mediastreamvalidator.

    So far I modified an existing encoding profile to try to achieve 64kbps total :

    ffmpeg -er 4 -i %s -f mpegts -acodec libmp3lame -ar 22050 -ab 32k -s 240x180 -vcodec libx264 -b 16k -flags +loop+mv4 -cmp 256 -partitions +parti4x4+partp8x8+partb8x8 -subq 7 -trellis 1 -refs 5 -coder 0 -me_range 16 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -bt 64k -maxrate 16k -bufsize 16k -rc_eq 'blurCplx^(1-qComp)' -qcomp 0.6 -qmin 10 -qmax 51 -qdiff 4 -level 30 -aspect 4:3 -r 10 -g 30 -async 2 - | %s %s %s %s %s

    but then when I try to validate it using mediastreamvalidator, it gives error after few ts :

    Playlist Validation : OK

    Segments :

    sample_cell_4x3_64k-00001.ts :

    WARNING : Media segment exceeds target duration of 10.00 seconds by 1.30 seconds (segment duration is 11.30 seconds)

    sample_cell_4x3_64k-00002.ts :

    WARNING : Media segment exceeds target duration of 10.00 seconds by 1.40 seconds (segment duration is 11.40 seconds)

    ....
    ....

    sample_cell_4x3_64k-00006.ts :

    ERROR : (-1) Unknown video codec : 1836069494 (program 0, track 0)
    ERROR : (-1) failed to parse segment as either an MPEG-2 TS or an ES

    sample_cell_4x3_64k-00007.ts :

    ERROR : (-1) Unknown video codec : 1836069494 (program 0, track 0)
    ERROR : (-1) failed to parse segment as either an MPEG-2 TS or an ES

    ....
    ....
    Average segment duration : 10.26 seconds
    Average segment bitrate : 376797.92 bps
    Average segment structural overhead : 349242.17 bps (92.69 %)

    Is there someway I can generate this correctly with just audio which totals 64kbps and turn it into mpeg-ts ready to be segmented and validated correctly ?

    Am I approaching the problem right ?
