• How Can I Determine the Correct Order to Merge .exo Files into a Single File Using ffmpeg ?

  13 août 2024, par Hiển Hồ

  I need to merge several .exo files collected from an Android app into a single .exo file. You can find the files here : Google Drive link.

  


  I'm planning to use ffmpeg for this task, but I'm unsure of the correct sequence for combining the files. I initially thought the sequence was based on the first number in the file names, but that doesn't seem to be the case.

  


  Can anyone provide advice on how to determine the proper order for merging these files ?

  


• FFMPEG drops supposedly corrupt frames from original video while transcoding using h264 encoder

  19 février 2019, par t6nand

  I am using h264 for optimising MP4 for web. I have a video which has some supposedly corrupt frame(s) within it’s initial 1-2 seconds. (Frame provided below)

  On transcoding using :

  ffmpeg -i orig.mp4 -c:v libx264 -crf 25 -vf scale="-2:min(ih\,720)" -b:v 600K -g 90 -c:a libfdk_aac output.mp4

  The output MP4 has these frames dropped out and I have my output with it’s start about 1 to 2 seconds delayed from original video, thus resulting in overall less time duration in output video.

  Moreover, most media players also skip these frames in playback (like quicktime player, etc). But VLC media player was able to play this video without skipping these frames.

  Is there a way to not drop frames using ffmpeg ? And if possible is it possible to identify and fix these frames in a video ?

  Note : I tried encoding same video using AWS Elastic transcoder which actually fixed these frames (Frame provided below) :
