• FFMPEG - Pipe Different HLS Resolutions to S3

  17 juillet 2019, par Mike

  I’m trying to save all my HLS output files directly to S3. As you can see in the code, I’m saving output files for many different sizes and bitrates. My issue is I can’t figure out how to save the files onto S3. I have managed to get this working on an EC2 instance where I save all the files on the same server, but once I try to use aws cli it fails. I can also get this working if it’s just one resolution.

  I’m guessing it has something to do with piping multiple aws cli commands since I can see it tells me Unknown options:, but I don’t see any other way of doing this.

  Also, I’m using the -progress flag so I can show the transcode progress to the user, can I pipe that directly to S3 as-well ?

  Note, the code below has been formatted to make it readable, it obviously doesn’t look like this when ran on the server.

• Trim video and extract thumbnail simultaneously

  12 septembre 2019, par Robin

  I am using the following two codes for ffmpeg.

  Trim Video :

  ffmpeg -i input.mp4 -ss 0 -t 100 -c copy -f mp4 output.mp4

  Create Thumbnail :

  ffmpeg -i input.mp4 -ss 1 -vframes 1 -f mjpeg output

  Which works as expected and is super fast, but when I combine the two like so :

  ffmpeg -i input.mp4 -ss 0 -t 100 -c copy -f mp4 output.mp4 -i input.mp4 -ss 1 -vframes 1 -f mjpeg output.jpeg

  ffmpeg runs a re-encoding copy rather than using -c copy. I really would like to execute both of these functions in a single ffmpeg command.

  Below is the output from terminal when it is generating the thumbnail, which is where it appears the re-encoding is happening.

• FFMPEG command not working on MP4 files as expected

  21 février 2020, par DavidB

  I am trying to set the output time offset for mp4 file.

  ffmpeg -ss 13.554000 -i input.mp4 -c copy -t 10 -output_ts_offset 13.554000 output.mp4

  This code works for WEBM file as expected but not for MP4.
  In webm it delays start time of video to the specified timestamp and duration is 23.554 but in mp4 it just cuts the video, start time is set to 0 and duration is 10
  Cannot find what is problem.

  ffmpeg -ss 12.960000 -i v.mp4 -c copy -t 10  -output_ts_offset 12.960000 output.mp4
