  • FFMPEG hangs when trying to receive rtp/udp stream

    22 décembre 2016, par NathanK

    I am trying to receive a udp stream encoded as h264. The exact command I am using is :

    ffmpeg -v 9 -loglevel 99 -re -i "udp://239.192.1.2:1234" outfile.h264

    The output I receive is :

    The problem with this is, obviously, that the ffmpeg process isn’t detecting any incoming packets on that address which causes the process to hang.
    I am, however, able to receive the stream using vlc, so I know that the packets are arriving. Here is a link to a similar problem.

    I thought, perhaps, it was a problem with reverse path filtering (as is mentioned in the link), but rp_filter is not set in /etc/sysctl.conf. I’m not quite sure what to do from here, any help is appreciated.

    Edit : I removed the @, however this changes nothing.

    The vlc command that works is :

    vlc --miface eth1 rtp://@239.192.1.2:1234

  • FFmpeg : how to stream multiple http outputs

    25 octobre 2022, par Caner Demir

    I'm assigned to search for a solution to stream more than one http output in ffmpeg. I tried the code below which uses pipe, but only the last output works, other ones don't work. The solutions I tried with tee muxer also couldn't work. Any idea how can I do that ?

    


    ffmpeg -re -i sample1.mp3 -i sample2.mp3 -filter_complex amix=inputs=2 -f mp3 pipe:1 | ffmpeg -f mp3 -re -i pipe:0 -c copy -listen 1 -f mp3 http://127.0.0.1:4000 -c copy -listen 1 -f mp3 http://127.0.0.1:4010


    


    The code I tried with tee muxer is below :

    


    ffmpeg -re -i sample1.mp3 -i sample2.mp3 -filter_complex amix=inputs=2 -c:a mp3 -f tee "[listen=1:f=mp3]http://127.0.0.1:4000|[listen=1:f=mp3]http://127.0.0.1:4010"


    


    edit : shared the log with code.

    


    ffmpeg -loglevel debug -hide_banner -re -i sample1.mp3 -filter_complex asplit=2 -c:a mp3 -listen 1 -f mp3 http://127.0.0.1:4000 -c:a mp3 -listen 1 -f mp3 http://127.0.0.1:4010

  • Filter complex apply on ffmpeg for android outputs low quality video

    17 septembre 2014, par Alin

    I finally managed to build ffmpeg as detailed in here : https://enoent.fr/blog/2014/06/20/compile-ffmpeg-for-android/ and in the end, I have a ffmpeg library which accepts command arguments.

    I am trying to apply a watermark image over the video so for it I am using preparing this ffmpeg command :

    ffmpeg -i input.avi -i logo.png -filter_complex 'overlay=10:main_h-overlay_h-10' output.avi

    I have first tried it on windows using ffmpeg.exe and the result was as expected.

    I have tried it on android using the compiled android and the output is as follows :
