  • ffmpeg transcoding stop after few seconds

    9 avril 2018, par Salem F

    Hi i’m trying to do this over week now with no success ,
    What’s i’m trying to do is transcoding video from live streaming source and downscale it with FFmpeg , but every time I start transcoding it broadcasting fro 11 Sec and stop . here last command I tried

      ffmpeg  -re  -i 'http://source.com/1034.ts' -preset ultrafast http://localhost:2052/feed1.ffm

    I tried to download the .ts file with IDM and it finish downloading the file on the exact 12 Sec that FFmpeg stop trans coding on it .

    does that means that FFmpeg download that file as one segment and not continued reading the source video As what video players does usually . BTW I tried with source with VLC player and it didn’t stop playing the the same source video .

    Edit :- I decide to pass FFmpeg command via FFserver config file ffserver.conf

    Launch ffmpeg -i 'http://source.com/1.ts' -copyinkf -codec copy  

    The stream works fine for a while but after testing couple sources I notice it’s struggle to trans-coding HD videos .

    I guess the issue with my VPS KVM server being very limited CPU and RAM ( 128MB only ) ! Since I tried using ultrafast preset but din’t solve the issue , another thing , I notice when I enable AVOptionVideo crf setting on ffserver.conf trans-coding runs bit smoothly without frame-rate dropping .
    Las my server uses Xeon L5520 CPU which is outdated CPU specially I gout 1/4 power of V single core (if they count HT it will be 1/8 of the real core ) :(

  • Demultiplex UDP live stream to multiple single live stream outputs using FFMPEG & FFSERVE

    22 mars 2018, par tiras muturi

    i have a problem with ffmpeg. i have an input live stream that has 8 inputs and i want to use ffmpeg to convert it from udp live steram to tcp livestream and then extract each of the 8 input stream differently.

    i have been reading about the ffmpeg documentation at they havent provided a clear way of solving my problem.

    am running

    ffmpeg version 3.2.4-1~16.04.york0 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 5.4.1 (Ubuntu 5.4.1-5ubuntu2~16.04.york1) 20170210 configuration: --prefix=/usr --extra-version='1~16.04.york0' --toolchain=hardened --libdir=/usr/lib/x86_64-linux-gnu --incdir=/usr/include/x86_64-linux-gnu --enable-gpl --disable-stripping --enable-avresample --enable-avisynth --enable-gnutls --enable-ladspa --enable-libass --enable-libbluray --enable-libbs2b --enable-libcaca --enable-libcdio --enable-libebur128 --enable-libflite --enable-libfontconfig --enable-libfreetype --enable-libfribidi --enable-libgme --enable-libgsm --enable-libmp3lame --enable-libopenjpeg --enable-libopenmpt --enable-libopus --enable-libpulse --enable-librubberband --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libspeex --enable-libssh --enable-libtheora --enable-libtwolame --enable-libvorbis --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx265 --enable-libxvid --enable-libzmq --enable-libzvbi --enable-omx --enable-openal --enable-opengl --enable-sdl2 --enable-libdc1394 --enable-libiec61883 --enable-chromaprint --enable-frei0r --enable-libopencv --enable-libx264 --enable-shared libavutil 55. 34.101 / 55. 34.101 libavcodec 57. 64.101 / 57. 64.101 libavformat 57. 56.101 / 57. 56.101 libavdevice 57. 1.100 / 57. 1.100 libavfilter 6. 65.100 / 6. 65.100 libavresample 3. 1. 0 / 3. 1. 0 libswscale 4. 2.100 / 4. 2.100 libswresample 2. 3.100 / 2. 3.100 libpostproc 54. 1.100 / 54. 1.100

    am running this command to help me split my input into multiple output that can be accessed differently.

  • Extract Video Frames In Python

    28 février 2024, par TheNone

    I want to extract video frames and save them as image.

    &#xA;&#xA;

    import os, sys&#xA;from PIL import Image&#xA;&#xA;a, b, c = os.popen3("ffmpeg -i test.avi")&#xA;out = c.read()&#xA;dp = out.index("Duration: ")&#xA;duration = out[dp&#x2B;10:dp&#x2B;out[dp:].index(",")]&#xA;hh, mm, ss = map(float, duration.split(":"))&#xA;total = (hh*60 &#x2B; mm)*60 &#x2B; ss&#xA;for i in xrange(9):&#xA;    t = (i &#x2B; 1) * total / 10&#xA;    os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))&#xA;

    &#xA;&#xA;

    But I have this error :

    What is wrong in my code ? Thanks in advance
