  • ffmpeg : how to stream from rtmp to FLS ?

    21 juin 2016, par yarek

    I can create HLS from static MPEG4 using that command :

    ffmpeg -i video.mp4 -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    I am now trying to achieve that :

    live RTMP(FME)------->FFMEG-------------->HLS

    enter image description here

    I tried with :

    ffmpeg -i rtmp://127.0.0.1:1935/live/video -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    But got error :

    Closing connection : NetStream.Play.StreamNotFound
    rtmp ://127.0.0.1:1935/live/video : Unknown error occurred

    Any idea how to achieve :

    RTMP---->FMPEG----->HLS ?

    I also tried :

    ffmpeg -i "rtmp://localhost:1935/live/yarek live=1" -codec copy -map 0 -f segment -segment_list out.list -segment_time 10 out%03d.ts

    Seems better but stucks :

  • FFMPEG can't find audio device for webcam on one computer

    13 mars 2018, par David

    I am building a webcam recording app. I am using FFMPEG to capture the audio and video. I have a Logitech C930 webcam.

    Notice the "Microphone (2- Logitech Webcam C930e)" audio device. I can capture from it using FFMPEG.

    Now, I move the same camera to a different computer (Intel Compute Stick) running nearly the same build of windows (16299.251 on the stick, 16299.248 on the laptop). Stick is 32-bit home and laptop is 64-bit Pro (shouldn’t matter, should it ?).
    I run the same command with the exact same camera and same drivers installed :

    No Audio device listed ? What ? If I use python’s sounddevice module, it sees the audio device :

    > python -m sounddevice
0 Microsoft Sound Mapper - Output, MME (0 in, 2 out)
 1 Remote Audio, MME (0 in, 2 out)
  2 Primary Sound Driver, Windows DirectSound (0 in, 2 out)

  4 Remote Audio, Windows WASAPI (0 in, 2 out)
  5 Microphone (Logitech Webcam C930e), Windows WDM-KS (2 in, 0 out)

    I can capture from that audio device with sounddevice, but I can’t get FFMPEG to capture from it.

    I have been trying to debug by removing and reinstalling drivers, etc, but to no avail. I also grabbed a Microsoft Lifecam webcam and got similar results. I can see the lifecam’s audio on the laptop but not the stick in just the same manner as the logitech camera.
    How can I get the audio device to show up on the stick so I can capture from it ?
