  • Convert MP3 bitrate from a stream into another stream with ffmpeg

    10 juillet 2013, par Léon Pelletier

    Using ffmpeg, I would like to know if it's possible to convert mp3 bitrate as data chunks are received ?

    That means I would send slowly chunks to ffmpeg so that it outputs a mp3 with another bitrate.

    So in very-pseudo-code, it looks like it :

    1. MP3 Request from user

    2. Send the default mp3 to ffmpeg with parameters to convert to the desired bitrate.

    3. As it's writing a new file, write what as been writen so far in the Response outputstream (I'm in ASP.Net)

    Is that feasable or I need to switch to another technology ?

    [EDIT]

    For now, I'm trying a solution like this : Convert wma stream to mp3 stream with C# and ffmpeg

    [EDIT 2]

    I answered my question, and it is feasible with an url as input and standard output as output. Using an url allows to process a file chunk by chunk, and using stdout, we can access data while it is processed.

  • Matplotlib animation MovieWriters fails on Ubuntu 12.04

    13 février 2013, par jjwebster

    I am attempting to save matplotlib animations to a movie via ffmpeg on Ubuntu 12.04 LTS (32-bit Desktop). Following the matplotlib example, it fails to load the animation writer : AttributeError: 'module' object has no attribute 'writers' (line 15 of the example) :

    import numpy as np
    
import matplotlib
    
matplotlib.use("Agg")
    
import matplotlib.pyplot as plt
    
import matplotlib.animation as animation
    

    
def update_line(num, data, line):
    
    line.set_data(data[...,:num])
    
    return line,
    

    
# Set up formatting for the movie files
    
Writer = animation.writers['ffmpeg']

    Via apt-get, I've tried installing ffmpeg, every codec imaginable, and even tried to compile ffmpeg from source. Nothing works.

    How do I get matplotlib to talk to ffmpeg on Ubuntu ?

  • ffmpeg to YouTube with tee mux giving resolution warning (65535x65535), which is not optimal

    I am streaming to YouTube and Facebook using ffmpeg , also writing data into disk (recording).

    


    it's working fine on Facebook and recording but on YouTube it's giving warning that is

    


    Please check the video resolution. The current resolution is (65535x65535), which is not optimal.

    


    and output on YouTube is also 1:1 aspect ratio due to the above resolution.

    


    I am using tee mux in ffmpeg Command.

    


    ffmpeg -f dshow -framerate 30 -i video="Integrated Webcam":audio="Microphone Array (Intel® Smart Sound Technology (Intel® SST))" -s 1920x1080 -c:v libx264 -r 30 -preset ultrafast -tune zerolatency -crf 28 -pix_fmt yuv420p -c:a aac -strict -2 -ac 2 -b:a 128k -t 4 -map 0 -f tee "[f=ismv]pipe:1 | [f=flv]rtmps ://youtube | [f=flv]facebook"
