  • ffmpeg - splitting, overlaying and selecting frame range in multiple input/outputs with complex video filter producing empty output

    11 octobre 2017, par Josep Carner

    I am trying to use ffmpeg to apply multiple filters -single input, multiple outputs-. In concrete, I am splitting the output in two, then applying an overlaying patch to one of those streams, split again and select a time range. The command I am using is :

      ffmpeg \
       -i ./dataset_test/videos/jz_10_huron_barstow.mkv \
       -an \
       -sn \
       -loglevel error \
       -filter_complex \
           "[0:v]split=2[L_in][F_in];
            [L_in]
               crop=226:307:21:74,scale=200x200,setdar=200:200,split=2\
            [L_in_0][L_in_1];\
            color=#808080:226x307,setpts=PTS-STARTPTS[L_PATCH];\
            [F_in][L_PATCH]
               overlay=21:74:shortest=1,scale=200x200,setdar=200:200,split=2\
            [F_in_0][F_in_1];\
            [F_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_0];\
            [F_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[F_1];\
            [L_in_0]select='between(t\,32\,212)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_0];\
            [L_in_1]select='between(t\,213\,393)',select='not(mod(n\,20))',setpts=(PTS-STARTPTS)/20[L_1]\
            "\
       -map [F_0] -an -sn ./out/jz_10_huron_barstow/F/0_F.mp4\
       -map [F_1] -an -sn ./out/jz_10_huron_barstow/F/1_F.mp4\
       -map [L_0] -an -sn ./out/jz_10_huron_barstow/L/0_L.mp4\
       -map [L_1] -an -sn ./out/jz_10_huron_barstow/L/1_L.mp4\

    For some reason, 0_F.mp4 is empty and 1_F.mp4 is cropped. My intuition is that it has something to do with applying splitting + overlaying + selecting. I think at some point some filter before select is changing the PTS of the frames in some way select is not properly discarding them, but I honestly don’t know how to solve it. Some insights :

    1. L_0 and L_1 are fine (no overlay is used in those two)

    2. If I suppress L outputs everything works fine (no "split" is needed at the beginning)

    Could someone provide some light ? I don’t really know what else to try.
    The logs with loglevel 40 are (some repeated lines ommited) :

  • capturing x11grab display from ffmpeg giveing "segmentation fault1 q=0.0"

    26 juin 2019, par user2369563

    In Debian 9, I am trying to record screen using ffmpeg over x11grab. it’s working great but sometimes its give error as shown below.
    Any idea what causing this ?

    exec error: Error: Command failed: ffmpeg -y  -f x11grab -s 1920x1080 -framerate 30 -i :1.0+0,0 -vsync 1 -c:v libx264 -preset ultrafast -crf 0 -pix_fmt yuv444p output.mkv
