  • ffmpeg - why I have three video streams in the output file when I have one video input (one video stream), one logo input

    17 July 2024, by Yazhou

    Hi I'm using ffmpeg to transcode some video files from prores or dv to h264/mov. Also I want to add a logo on it and make some other changes.
The command line I use is

    


    ffmpeg -i input.mov -i logo.png -c:a aac -c:v libx264 -pix_fmt yuv420p -crf 18 -map 0:a? -map 0:v -filter_complex "yadif,[1]scale=iw*1:-1[wm];[0:v:0][wm]overlay=main_w-overlay_w-5:5" -disposition:v:0 default output_h264.mov

    


    And what I got has three video streams. One for the logo,one for the video with logo, and one for original video.

    


    Though I put the default video stream as the one with both video and logo as you can see for -disposition:v:0 default, and it's also playing that stream. But when I tried to upload it on Vimeo or Youtube, it uses the wrong stream.

    


    


    How can I change the command line to let ffmpeg only output one stream?
And how can I remove the extra streams for the existed outcomes?

    


  • Copy codecs setting from video or how to join video using ffmpeg [closed]

    6 December 2012, by Степан Талабира

    We have 2 videos:
    test1.mp4 and test2.mp4

    How do I convert video 1 with parameters video 2 ? (for join them together)

    I tried to pull out the parameters of video using ffmpeg-php.
    But the result is bad .. mkvmerge or MP4Box not join this result video.
    Mencoder says that the video codec settings is different...

    Сan anyone tell me how to blind 2 video (the first small and second big) without re-encoding the second movie
    Video mp4 H.264.

  • ffmpeg split | merge video voice not sync

    2 August 2022, by Zhang

    there are what i done:

    


      

    1. download a full mp4 file.

      2. 


    2. due to it's watermark(0s-10s), i split the full video into 2 parts from 10second. the first part with watermark.

      3. 


    3. use ffmpeg delogo the first part.

      4. 


    4. merge the two video into a full again.

      5. 


    


    

    wget -O download.mp4
ffmpeg -i download.mp4 -vcodec copy -acodec copy -t 00:00:10 tmp1.mp4
ffmpeg -i download.mp4 -vcodec copy -acodec copy -ss 00:00:10 tmp2.mp4
ffmpeg -i tmp1.mp4 -vf "delogo=x=432:y=44:w=1060:h=108" -c:a copy tmp3.mp4
echo file tmp3.mp4 > mergelist.txt && echo file tmp2.mp4 >> mergelist.txt
ffmpeg -f concat -i mergelist.txt -c copy output.mp4


    


    


    problem i faced:
in the last merged video, only one tmp part is fine, the other's video and voice not sync and play time more faster than before.

    


    why i divide it, delogo(although only the first 10 seconds shows) full video more than 1h, re-encode takes much time, 10s part fine to me.
