  • Want to send a video from desktop to Wowza using ffmpeg

    3 mars 2018, par ST94

    I am trying to stream a local .mp4 video file from my laptop to Wowza Streaming Engine using ffmpeg. Both systems are able to ping each other. I give the following command on my laptop

    ffmpeg -re -i bunny_1080p_60fps_normal.mp4 -vcodec libx264 -acodec aac -ar 48000 -strict experimental -f flv "rtmp://192.168.1.22:1935/live/myStream"

    192.168.1.22 is the IP address of Wowza server residing on another system running Ubuntu 17.04.

    I see the following on the command prompt of my laptop when I give the above command,

    Can anyone please tell me what the exact procedure is to stream a video file to Wowza .

    How will I be able to view the stream at Wowza ?

  • How can I convert audio to WAVE_FORMAT_PCM using FFmpeg ?

    16 juin, par Eric Stdlib

    I am using Python's wave module to read audio, and using FFmpeg to convert audio from other types to wav. However, I am encountering some problem.

    



    I wrote v.py to generate an silence audio file a.wav

    



    import sys, wave, math
import numpy as np

wave_data = np.zeros(44100).astype(np.short)

f = wave.open('a.wav', 'wb')
f.setnchannels(1)
f.setsampwidth(2)
f.setframerate(96000)
f.writeframes(wave_data.tostring())
f.close()


    



    Then I used FFmpeg to "copy" a.wav to b.wav (though it seems to encode / decode the file), but I can only read a.wav with Python ; b.wav cannot be opened.

    



    [user@localhost tmp]$ ffmpeg -i a.wav b.wav&#xA;Guessed Channel Layout for Input Stream #0.0 : mono&#xA;Input #0, wav, from &#x27;a.wav&#x27;:&#xA;  Duration: 00:00:00.46, bitrate: 1536 kb/s&#xA;    Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 96000 Hz, mono, s16, 1536 kb/s&#xA;Stream mapping:&#xA;  Stream #0:0 -> #0:0 (pcm_s16le (native) -> pcm_s16le (native))&#xA;Press [q] to stop, [?] for help&#xA;Output #0, wav, to &#x27;b.wav&#x27;:&#xA;  Metadata:&#xA;    ISFT            : Lavf57.71.100&#xA;    Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 96000 Hz, mono, s16, 1536 kb/s&#xA;    Metadata:&#xA;      encoder         : Lavc57.89.100 pcm_s16le&#xA;size=      86kB time=00:00:00.45 bitrate=1537.8kbits/s speed= 706x    &#xA;video:0kB audio:86kB subtitle:0kB other streams:0kB global headers:0kB muxing overhead: 0.115646%&#xA;[user@localhost tmp]$ python3&#xA;Python 3.6.4 (default, Jan 23 2018, 22:25:37) &#xA;[GCC 7.2.1 20170915 (Red Hat 7.2.1-2)] on linux&#xA;Type "help", "copyright", "credits" or "license" for more information.&#xA;>>> import wave&#xA;>>> wave.open(&#x27;a.wav&#x27;)&#xA;&#xA;>>> wave.open(&#x27;b.wav&#x27;)&#xA;Traceback (most recent call last):&#xA;  File "<stdin>", line 1, in <module>&#xA;  File "/usr/lib64/python3.6/wave.py", line 499, in open&#xA;    return Wave_read(f)&#xA;  File "/usr/lib64/python3.6/wave.py", line 163, in __init__&#xA;    self.initfp(f)&#xA;  File "/usr/lib64/python3.6/wave.py", line 143, in initfp&#xA;    self._read_fmt_chunk(chunk)&#xA;  File "/usr/lib64/python3.6/wave.py", line 260, in _read_fmt_chunk&#xA;    raise Error(&#x27;unknown format: %r&#x27; % (wFormatTag,))&#xA;wave.Error: unknown format: 65534&#xA;>>> &#xA;</module></stdin>

    &#xA;&#xA;

    How should I change the command of FFmpeg to convert the file to WAVE_FORMAT_PCM, so that I can read b.wav with Python ?
