  • Python FFmpeg : Unable to set audio stream language

    15 décembre 2019, par Cryptonaut

    I’m using this Python library to programmatically generate a .MOV using a single .WAV (pcm_s24le - 24 bit - 48000 Hz) as input.

    I’ve already asked a few questions relating to other aspects of my video pipeline, seen here and here.

    All I’m trying to do is assign the eng language tag to a single audio stream in the .MOV output.

    Here’s my code :

        audio = ffmpeg.input(input_audio)
    

    
    output = ffmpeg.output(audio, output_audio,
    
    acodec='copy',
    
    audio_bitrate=bitrate,
    
    metadata='s:a:0 language=eng')
    

    
    output.run()

    The .MOV output this generates displays the following via FFprobe :

    • Stream #0:0: Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, stereo, s32 (24 bit), 2304 kb/s (default)

    However, when I run the same input file using the same options/parameters via command line :

    • ffmpeg -y -i input_audio.wav -c:a copy -metadata:s:a:0 language=eng output_audio.mov

    FFprobe states the stream language is eng :

    • Stream #0:0(eng): Audio: pcm_s24le (in24 / 0x34326E69), 48000 Hz, stereo, s32 (24 bit), 2304 kb/s (default)

    Why is the command line approach outputting Stream #0:0(eng) but not the programmatic approach ?

  • Which Platform/Language to choose for Video Management System [closed]

    5 décembre 2019, par Vivek Buddhadev

    We have started on a new project, Which enables for the multiple IP cameras(Around 1000 Cameras) to record as well as available for live streaming.

    Like https://www.security.honeywell.com/uk/product-repository/maxpro-vms

    Initially, we have tried using ffmpeg commands that saves data in chunks :

    ffmpeg -i {rtsp_url} -fflags flush_packets -max_delay 2 -flags -global_header \
    
    -hls_time 2 -hls_list_size 3 -vcodec copy -y /var/www/html/Cam01.m3u8

    Then we have started http server and using node.js we are displaying the stream.

    But as we are adding more cameras into it, the performance is going down.

    Kindly suggest if there is any other way to achieve this functionality which help us to fulfill the above requirement.
