  • FFMPEG : change input without stoping proccess

    10 juillet 2018, par admin883

    how i can change input on ffmpeg without stop process on linux Debian 9 ?
    im user decklink input and i need to change to file mp4 input.

    ffmpeg -f decklink -i 'DeckLink Mini Recorder' -vf setpts=PTS-STARTPTS -pix_fmt uyvy422 -s 1920x1080 -r 25000/1000 -f decklink 'DeckLink Mini Monitor'

  • How to overlay images sequence from pipe over a video stream with ffmpeg ?

    7 juin 2018, par Dotan Simha

    I’m trying to figure out an issue with ffmpeg.
    I have the following installation :
    - DeckLink Mini Recorder Card (for HDMI input)
    - DeckLink Mini Monitor Card (for HDMI output)

    I’ve successfully managed to take the HDMI input from the Decklink card and output is as-is to the output card with the following command :

    ffmpeg -f decklink -video_input hdmi -raw_format yuv422p10 -i "DeckLink Mini Recorder" -f decklink -pix_fmt uyvy422 "DeckLink Mini Monitor"

    I tried to add a complex-filter to add an overlay of an image, with the following command, and it works :

    ffmpeg -f decklink -video_input hdmi -raw_format yuv422p10 -i "DeckLink Mini Recorder" -i ./tools/bin/windows/2.png -y -filter_complex "[0:1][1:0]overlay=10:10" -f decklink -pix_fmt uyvy422 "DeckLink Mini Monitor"

    I’m getting a realtime feed from the decklink recorder, the image is added to the stream, and it outputs it to the output HDMI card. Everything seems to work.

    Now I tried to change the static image path to use stdin (pipe:0), and I have a tool that constantly streaming PNG images to stdout :

    ffmpeg -f decklink -video_input hdmi -raw_format yuv422p10 -i "DeckLink Mini Recorder" -i pipe:0 -y -filter_complex "[0:1][1:0]overlay=10:10" -f decklink -pix_fmt uyvy422 "DeckLink Mini Monitor"

    The result that i’m getting on the output HDMI card is a static image, of the first frame.
    The output of ffmpeg also changes now, and it looks like it stuck of the first-second of the stream :

    ```
    frame= 30 fps=7.4 q=-0.0 size=N/A time=00:00:01.00 bitrate=N/A speed=0.247x

    frames : 30,
    currentFps : 7,
    currentKbps : NaN,
    targetSize : NaN,
    timemark : ’00:00:01.00’
    ```

    It just remains on 00:00:01.00 and never changes.

    I tried to find the issue, and did the following :

    • Tried to stream Decklink Recorder -> static png file overlay -> Decklink Monitor = IS WORKS

    • Tried to stream static png file -> Decklink Monitor = IS WORKS

    • Tried to stream pipe:0 (PNG files) -> Decklink Monitor = IS WORKS

    • Tried to stream Decklink Recorder -> pipe:0 (PNG files overlay) -> RAW AVI file IS WORKS

    The only issue is with :
    - Tried to stream Decklink Recorder -> pipe:0 (PNG files) overlay -> Decklink Monitor DOES NOT WORK

    I suspect that Decklink output is more strict, and my pipe:0 with the PNG images is not stable, and the combination of both causes it to freeze.

    Any idea how to solve it ? :(

    Thanks !

    Mais pour l’ajout là c’est bizarre on voit pas le fond, c’est un peu nul, en tout cas pour cette couleur.
    Peut-être l’inverse aussi, le retrait est plus gros que l’ajout : ça ne va pas. C’est le retrait qui devrait être en mini+link (très peu mis en avant), et l’ajout en normal, ni link, ni peut-être mini non plus.
