  • ffmpeg add text every second with enable between filter

    12 janvier 2023, par HUNG
    ffmpeg -y -i public/media/vid1.mp4 -vf "drawtext=text='1':x=w-tw-50:y=50:fontcolor=black:fontsize=380:enable='between(t,1,2)',drawtext=text='2':x=w-tw-50:y=50:fontcolor=black:fontsize=380:enable='between(t,0,1)'" -codec:a copy public/media/vid1-1.mp4


    


    I want to add a number every second in a video. I googled and the syntax should like the above. However, only the text within between(t,0,1) can be shown and the value is keeping shown for the whole video duration. But I expected it should only show one second.

    


    I expected between(t,1,2) can show the text from 00:00:01-00:00:02. However, it never show.

    


  • Concatenating different rotated videos with ffmpeg

    14 avril 2017, par acilander

    I am trying to concatenate two videos with ffmpeg having different rotation metadata tags. The first one has rotation=180 the other one has no tag at all.

    There are two methods that can be used in ffmpeg : concat demuxer / concat protocol. Protocol is working as expected but demuxer method is not. When I use concat demuxer option in ffmpeg with copy option to avoid re-encoding the following happens :

    First video with rotation = 180 will be rotated correctly. But the second video without rotation flag will also be rotated and will be presented upside down in output video.

    I know about the options to remove rotation metadata or the possiblility to use filters to rotate the videos. But my question is if someone knows if this is expected behaviour of ffmpeg or not. For me it seems like ffmpeg uses rotation metadata from first video and uses it for all other concatenated videos. Is this assumption correct and intended ?

    Thank you for any feedback and explanations.

make: *** [ffmpeg_frame.lo] Error 1

    i read that if i get the

    make: *** [ffmpeg_frame.lo] Error 1

    error , i replace all *PIX_FMT_RGBA32* with *PIX_FMT_RGB32* inside *ffmpeg_frame.c*. but when i search the file , there is no *PIX_FMT_RGBA32* . there are all PIX_FMT_RGB32 ! .
    so i have no idea what is wrong with it .
    can anyone please help me get this going ?
    Thanks in advance

    Edited :
    Thanks to God , i finally found the cause of the problem .
    when i was trying to replace PIX_FMT_RGBA32 with PIX_FMT_RGB32 inside ffmpeg_frame.c* using VI i mistakenly messed the source code (the ffmpeg_frame.c) and removed a comment sign (*/ ) and that messed just everything :)
    i re extracted all files and then replaced all PIX_FMT_RGBA32 with PIX_FMT_RGB32 and everything compiles just fine :)
