  • ffmpeg faild when processing video from stream

    17 octobre 2019, par Milousel

    I create ffmpeg method for modify video from readstream as input. I test it on videos which I download from internet and it’s works good. When I tried it on video from my phone it crash. I tried to modify (take off few second) video from internet and try it again, but I receive the same error message.

     an error happened: ffmpeg exited with code 1: pipe:0: Invalid data found when processing input
    
Cannot determine format of input stream 0:0 after EOF
    
Error marking filters as finished
    
Conversion failed!

  • Are there differences between the parameters of different versions of ffmpeg ?

    13 octobre 2019, par Mauro Alejandro Pereira

    I want to obtain a different raw video for each frame of an MP4 file.
    My instruction works in an old version of ffmpeg but not in the new one.

    In the mp4 file there are 137 frames. It is checked. The versions are installed on different machines.

    Versions 2.8.15 :

    $ ffmpeg -i ./video.mp4 -vf fps=30 -vframes 137 -vcodec rawvideo -s '1920x1080' -pix_fmt gray -threads 0 frame%08d.raw

  • using ffmpeg.js to play H265 video, only play hvc1 format, can't play hev1 format, is there anyway to play hev1 ?

    1er novembre 2019, par Alex

    I compiled ffmpeg into ffmpeg.js and ffmpeg.wasm by using emscripten, so that it can run in the browser and play H265 video.

    However, I found that only the hvc1 format can be played.
    Like that：

    Stream #0:0(und): Video: hevc (Main) (hvc1 / 0x31637668), yuv420p(tv, bt709, progressive), 1280x720, 854 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)

    and the hev1 format cannot be played.Like that :

    Stream #0:0(und): Video: hevc (Main) (hev1 / 0x31766568), yuv420p(tv, progressive), 1920x1080 [SAR 1:1 DAR 16:9], 829 kb/s, 25 fps, 25 tbr, 12800 tbn, 25 tbc (default)
