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

    26 novembre 2015, 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)

    /root/bin/ffmpeg    -threads 1 -y  -i /home/flirtzo/public_html//userfiles/files/94e76a18a7838e62ecb23cf0c374b1b798e7b936  -threads 0 -codec:a libfdk_aac -b:a 128k  -vf "scale=-2:320" -preset veryslow -vcodec h264 -acodec aac -strict -2  /home/flirtzo/public_html/userfiles/files/b2/72/695f4eba95169a3f29564bf9571c703b05f1b5974f5156da633eb139c80a1575452e2858dfc61cc82bfca02d2b156aa64d4503695756481dc2a5d1c673a4cdea-94e76a18a7838e62ecb23cf0c374b1b798e7b936.mp4

  • 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)

  • video after ffmpeg command conversion is not playing on windows

    10 décembre 2015, par Hemant Kumar

    I am stuck at a very weird and complex problem, hoping if anyone know the solution :

    I am converting user uploaded video using ffmpeg command on server and it was working fine as well. Today I found that if a video is recorded by a webcam from windows, is playing well in linux as well as on windows where as if user is creating a video by webcam from linux, is playing only on linux (any browser). On window it’s screen either show loading icon or black screen while audio is working fine.

    I am using following codec :

    ['-strict', '-2', '-preset slow', '-maxrate 500k', '-bufsize 1000k', vfOption, '-threads 0', '-ab 64k', '-movflags faststart','-vf scale=-1:480', '-metadata:s:v:0 rotate=0', '-vcodec libx264']

    I work on linux and using html5 player on my website. I am converting video in mp4 format.

    Input :

    ffmpeg -i /<server path="path">/stream_FE2AF05B-E630-1F7B-390B-37325B31B362.flv -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ' -threads 0 -ab 64k -s 640x480 -movflags faststart -metadata:s:v:0 rotate=0 /<server path="path">/testing.mp4
    
</server></server>
