  • How can I save local video file to django FileField ?

    11 janvier 2021, par Nina deRossi

    I create a local video file (.mp4) by adding a logo to an existing video with the following code :

    


            logo_path = os.path.join(MEDIA_ROOT, 'logo.png')

        logo = (mp.ImageClip(logo_path)
                .set_duration(video.duration)
                .resize(height=50)  # if you need to resize...
                .margin(right=8, top=8, opacity=0)  # (optional) logo-border padding
                .set_pos(("right", "top")))

        video_path = os.path.join(MEDIA_ROOT, 'test7.mp4')
        audio_path = os.path.join(MEDIA_ROOT, 'temp-audio.m4a')

        final = mp.CompositeVideoClip([video, logo])
        final.write_videofile(video_path, codec='libx264',
                              audio_codec='aac',
                              temp_audiofile=audio_path,
                              remove_temp=True
                              )


    


    I want to save the new video to a FileField of my model.
Here is the code :

    


       f = open(video_path)
   flick.videoWithWatermark.save("videoWithWaterMark.mp4", File(f))


    


    I keep getting the error :
'ascii' codec can't decode byte 0xd1 in position 42 : ordinal not in range(128)

    


    How can I save the video to a FileField ?

  • Cannot find a proper format for codec ‘h264’ (id 28), pixel format ‘none’

    20 avril 2022, par 이중범

    I downloaded jocover’s git hub ffmpeg and compiled it to stream the video to the web on the Jetsonano board
However, i tried

    


    ffmpeg -c:vh264_nvmpi -i /dev/video -f null -


    


    


    Cannot find a proper format for codec ‘h264’ (id 28), pixel format
‘none’ (id-1)

    


    Assertion *codec_id != AV_CODEC_ID_NONE failed at
src/libavdevice/v4l2.c:811

    


    


    I got this error

    


    and I tried ./ffmpeg -encoders |grep 264

    


    As a result of this console, the output is as follows :

    


    


    v… h264_nvmpi nvmpi H.264 encoder wrapper (codec h264)

    


    


    


    v… h264_v4l2m2m V4L2 mem2mem H.264 encoder wrapper (codec h264)

    


    


    


    v… h264_vaapi H.264/AVC (VAAPI) (codec h264)

    


    


    The camera specs are like this maybe Sony IMX219, a model called Raspberry Pi Camera Module V2

    


    


    ioctl : VIDIOC_ENUM_FMT

    


    Index : 0

    


    Type : Video Capture

    


    Pixel Format : ‘RG10’

    


    Name : 10-bit Bayer RGRG/GBGB

    


    


    I’d really appreciate your help

    


    thx
