• ffmpeg mp4 x264 encoding -> playback causes "pending" in both crome and IE causing 10+ seconds delay

  29 septembre 2014, par user1978645

  After encoding a video to mp4(x264 with aac) ; I have the following weird behaviour in both crome and IE :

  Im serving the content from https with spdy enables.

  It takes up to 30 seconds before the video is actually played, in the mean time i cannot reload the page it shows up as "pending". (even after i have visual on the video sometimes it takes 10-20 seconds before i can actually reload the page, or navigate to another url on the same domain)

  After looking at the "network" tab in developer tools, i see the following requests for 1 page/video :

  Path        Method Status   Type         Initiator   Size/content  Time/latency
  
  video.mp4   GET    206 OK   video/mp4    other       32.3KB/32.0kb  600ms/339MS 
  
  video.mp4   GET    206 OK   video/mp4    other       123kb/123b     21.85s/21.46s
  
  video.mp4   GET    206 OK   video/mp4    other       7.1MB/7.2MB    1.4min/2ms

  I tried to isolate the problem, When i use an mp4 video from the internet (for example the demo video of jplayer) and load it from my server, it loads rapidly, without delays.

  So it makes me think the problem lies within the encoding. I tried various things.
  FFmpeg :

  • csr 69 (low quality)

  • various options

  HTML :

  • preload="none"

  • javascript loading/playing of the movie

  • type=’mp4/video’

  • no posterimage

  But i cannot resolve the problem. Does anyone have a clue what is causing this ?

  I have a download speed of 300kb/s and the movie is 6MB.

  After the video starts, the video isn’t fully buffered, so i wonder : What is the html5 videoplayer doing all this time ?

  The problem also blocks the connections. When i press "F5" in both chrome and IE the page beeing reloaded comes up in the network tab as "pending" and it can take 10 to 20 seconds before the page actually reloads.

  ffmpeg command : (i used various commands but this is just 1 example which causes the problem)

• What causes Firefox to refuse playing one specific MP4 that plays well on other browsers, resolution being the only difference ?

  3 décembre 2014, par Faro

  I’m a developer for a PHP powered website that allows the upload of videos which get converted to MP4 using ffmpeg. This setup worked pretty well so far, however today I came across a report of a user that couldn’t play one of the files in Firefox.

  I was unable to replicate the issue on my own machine at first, but using a fresh install of Windows 7 I actually got the same issue : The file will not play in Firefox, but works fine in Chrome. If called up directly, Firefox will say "Video can’t be played because the file is corrupt".
  When downloaded, Windows will also not create a thumbnail of the video for the file and WMP will only play the audio part.

  On my own machine the file works perfectly in WMP which made me wonder if it could be a codec issue (I do have the K-Lite Codec Pack installed), however I’ve compared the file to a working one and the only difference is the resolution, filesize and the format profile which is "High@L3.1" for a working file with a 720p resolution and "High@L4.0" for the non-working one (which is 1600x1200).

  I then read through the Wikipedia article on H.264/MPEG-4 AVC and began to wonder if the level might be the issue, and the tool I used (XMedia Recode) actually did not allow me to set a height bigger than 1080 on Level 4, however when I set the level to 5 and encoded the file again, it still wouldn’t play.

  I did find a note on the MDN page of supported formats which reads :

  Firefox/Firefox for Android/Firefox OS supports the format in some cases, but only when a third-party decoder is available, and the device hardware can handle the profile used to encode the MP4.

  I’m assuming that is why the codec pack would allow Firefox to play even the ’broken’ file on my machine, I still don’t understand though why Firefox does play some files but not this one, especially when Chrome on the same machine plays all of them.

  The line in PHP that starts the conversion is as follows :

  exec("/usr/local/bin/ffmpeg '-i' '" . $file_in . "' '-qscale' '4' '-y' '-threads' '1' '-acodec' 'libvo_aacenc' '-vcodec' 'h264' '" . $file_out . "' 2>&1", $buffer, $success);

  This should produce correct files, and this is indeed the first time a file has issues.

  I’ve uploaded a zip with 3 versions of the file, the untouched one, the converted one with the same settings the website would use, and another converted one with level 5.

  Maybe I’m missing something obvious, but I couldn’t find anything wrong with it, what do I need to change in order to produce a file that will work natively in Firefox ?

  Also, this is my first question on SO, so if you see anything that I can improve, please let me know :-)

  Edit : This is the output of calling ffmpeg (with the faststart option)

• FFMPEG output (Images > Video) is unplayable

  23 décembre 2014, par jgads

  I’m using FFMPEG to make a video slideshow from a group of images on Android. The process completes successfully and the output file is the correct/expected size (or the same as what is reported in FFMPEG’s ’progress’), but the video does not play on any Android video player (MXplayer, VLC, stock). The video players show a perpetual loading circle and never actually launch. MXplayer can see the file and generate a thumbnail but not actually play it. Here is the command :

  ffmpeg -f image2 -re -r 1 -i
  /storage/emulated/0/Pictures/phototest/%d.jpg -vcodec libx264 -f mp4
  -r 24 -preset : ultrafast -an -threads 4 -b 4000k -mbd rd -flags +mv4+aic -trellis 2 -cmp 2 -subcmp 2 -g 300 -y -pix_fmt yuv420p /storage/emulated/0/Pictures/phototest/result1.mp4

  Here’s the output via Android Logcat :

  EDIT : Note that although it appears to run ffmpeg twice here, the output file is the correct size which seems to mean that the file isn’t getting overwritten with a corrupt version, so we can probably just assume there’s a bug with Logcat (right ?)

  EDIT 2 : Trying the same command on the PC works flawlessly. Playing back this video works fine on Android.
