• How to output mp4 after concatenation using ffmpeg

  27 août 2019, par Patrick

  I want to merge a couple of mp4 videos (with different fps, heigth, width and bitrate).

  I tried this with a few videos, but it always hides or skips some video files from the input.txt.

  How can I correctly merge those mp4 files ?

  Thank you !

  My command :

  ffmpeg, "-f", "concat", "-i", "concatfile.txt", "-c:v", "copy", "-sn", "-y", "merged_video.mp4", "-max_muxing_queue_size", "1024"

  -> the video does not play correctly

  EDIT :
  i now output the information of each video in concat.txt_

  Could be the issue, that the last mp4 has mono audio ?

• Why we get co located POCs unavailable while encoding a video using ffmpeg ?

  22 août 2019, par geo-freak

  I am trying to encode a video to m3u8 file. I am inserting blackframes when the video has no source in between. I used the following command to encode the video. I found the options in ffmpeg website to insert the filters and blackframes. But I am failing after making some changes as per stackoverflow and from other sources.

• How to convert mp4 file so that it can allow timeline drag in html5 video tag ?

  21 août 2019, par sgon00

  I generated a mp4 file by ffmpeg. And then correct the index by qt-faststart. But now, there is still one problem. In chrome browser, the video timeline can not be dragged. I tried another online video with the same video tag code. (for instance : http://www.w3schools.com/html/movie.mp4). The timeline dragging works fine. Can anyone please teach me how to enable timeine drag for this video ? How can I convert the mp4 file to make it right ? Thanks a lot.

  Updated :

  I kinda found the problem and fixed it. My debug http server is picky. So when I use nginx server, the mp4 video timeline can be draggable.

  But the weird part is the timeline of the movie.mp4 from w3schools.com works in my debug http server. So I don’t know the true cause, but changing to production http server solved the problem.
