  • how do I stream a single image in a loop to a video device ? [closed]

    19 décembre 2019, par ufk

    I am trying to stream a single image to a video device in Linux.

    currently I am using Gentoo Linux with FFMpeg 4.2.1 but ffmpeg is not a requirement, if there is a better tool for the task i’m up for it.

    so I’m running the command

    ffmpeg -loop 1 -i binary-file.png -c:v -f v4l2 /dev/video0

    and this is the output that I get :

  • Getting RTSP/1.0 404 Not Found after ANNOUNCE message

    21 décembre 2019, par Joseph Matan

    I’m trying to stream a video with FFmpeg to Gstreamer-RTSP-Server (it’s actually a docker that runs the Gstreamer-RTSP-Server).
    The OPTION message gets a "RTSP/1.0 200 OK" response. However, the ANNOUNCE message gets "RTSP/1.0 404 Not Found" response.

    This the FFmpeg command (which works OK with a different RTSP-Server) :

    ffmpeg -f v4l2 -i /dev/video0 -c:v libx264 -intra -an -f rtsp -rtsp_transport tcp rtsp://192.168.1.10:8554/test

    This is the messages sequence snapshot from Wireshark :

    Any idea why the ANNOUNCE message fails ?

    The Gstreamer-RTSP-Server is part of a docker, and I guess it runs with a default Gstreamer pipeline parameters - maybe that’s can cause the issue ?

  • pydub not encoding file correctly

    21 décembre 2019, par geoffr98

    I’m trying to use pydub to take an audio stream in opus format and save it as a wav. I am currently using a file instead of a stream and it is not working.

    My code :

    myfile = open("Short_Test.opus", 'rb')
    
opus_audio_bytes = myfile.read()
    
myfile.close()
    
opus_data = BytesIO(opus_audio_bytes)
    
sound = AudioSegment.from_file(opus_data, codec="ogg")
    
print("Export now")
    
mywave_file = sound.export("mashup.wav","16k")

    It does create mashup.wav, however it is not created correctly. Here is the log output from pydub :

    subprocess.call(['ffmpeg', '-y', '-i', '-', '-acodec', 'pcm_s32le', '-vn', '-f', 'wav', '-'])
    

    
Export now

    I am confused as to why it isn’t working because the following ffmpeg command on the command line works, so I’m sure it’s my parametes in pyusb :

    ffmpeg -i Short_Test.opus -b:a 16000 mashup.wav

    Any ideas as to how to fix my problem ?
