• Rails : MP4 videos showing up blank in Firefox (but works in Chrome)

  10 février 2015, par Mark Boulder

  I got this Rails app with uploaded MP4 videos that play back just fine in Chrome - but why do they show up blank in Firefox ?

  The video appears on the page and plays just fine if I download it :

  <video loop="loop" src="/path/to/whatever.mp4?1234567"></video>

  From Rails I did :

  <%= video_tag photo.attachment_url(:medium) %>

  I tried adding Mime::Type.register "video/mp4", :mp4 to config/initializers/mime_types.rb but to no avail.

  Live app : http://runnable.com/VNkNeJ9wpNZJBEma/paperclip-mp4-problem

  Click Run and navigate to the last post to see the MP4. Note that Runnable is very slow. If it says something bad happened in the terminal, try reloading the page until it disappears.

• why ffmpeg trimming videos while converting to m3u8 ?

  6 janvier 2017, par Puneet Singh

  I am using ffmpeg version 3.2.2, and converting mp4 and mov files to m3u8 format by below command.

  ffmpeg -i test.mov output.m3u8

  The length of test.mov is around 3 min, but it convert it to last 24-25 seconds of only, when I play that m3u8 in player. I even merge all the segments of m3u8 to confirm the length of video, by command

  ffmpeg -i output.m3u8 -c copy -bsf:a aac_adtstoasc output.mp4 

  the output.mp4 is also 24-25 sec, the last 24 seconds of test.mov.

  I don’t know what is wrong, it is working with small length input files like 10 seconds file.
