    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • FFmpeg copying from udp to rtsp

    28 décembre 2014, par ladi2000

    So I have a (live)video stream on udp ://10.5.5.100:8463 and I copy it to udp ://localhost:1000.

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy udp://localhost:1000/go

    And it works fine in VLC but Wirecast doesn’t accept udp ://..., but it accepts rtsp ://...

    but I don’t now much about ffmpeg, so I only changed udp to rtsp

    ffmpeg -f mpegts -i "udp://10.5.5.100:8554?fifo_size=10000" -f mpegts -vcodec copy rtsp://localhost:1000/go

    But it doesn’t work and outputs this

    rtsp://localhost:1000/go: Protocol not found

    Thank you for answers !!

  • ffmpeg error while converting to mp4 Error while opening encoder for output stream #0.0

    20 mars 2016, par Josh

    I am trying to convert various file types to mp4 to be displayed using ffmpeg, but i keep getting the error :

    Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height

    Another piece that looks important is :

    [libx264 @ 0x93caef0] broken ffmpeg default settings detected

    [libx264 @ 0x93caef0] use an encoding preset (e.g. -vpre medium)

    [libx264 @ 0x93caef0] preset usage : -vpre -vpre

    [libx264 @ 0x93caef0] speed presets are listed in x264 —help

    [libx264 @ 0x93caef0] profile is optional ; x264 defaults to high

    The latest code I am running is :

    ffmpeg -i source -s 320x240 -r 30000/1001 -b 200k -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k destination

    I have seen a few other people with this issue, but their fixes didn’t work for some reason.

    In case it matters : ultimately this will be used in php, though I am trying to get it working first via putty

    EDIT: : Here is the full thing as requested(using a wmv, have tested wmv and flv) :

         ~ >> ffmpeg -i path.wmv -s 320x240 -r 30000/1001 -b 200k -r 29.97 -bt 240k -vcodec libx264 -coder 0 -bf 0 -refs 1 -flags2 -wpred-dct8x8 -level 30 -maxrate 10M -bufsize 10M -acodec libfaac -ac 2 -ar 48000 -ab 192k path.mp4
