  • FFMPEG Converted Video Not Working In HTML5

    27 novembre 2015, par Suprabhat Biswal

    Converted Avi to Mp4 using FFMPEG, Converted video not working in html
    5

    I have a section in my web page where user can upload any types of videos of any format , currently only restricted to .mp4 and .avi. After successfull upload i have displayed the same video to the user. I have bind the path in HTML5 video so that the user can view the content he/she has uploded. Video with extension .mp4 no doubt are working properly as HTML5 support them. Tricky part is it don’t support Avi files. Now here what the problem has arised. In order to display avi videos i have used FFMPEG to convert videos with extension .avi to .mp4. With lots of googling and reading forum, i have succesfully converted avi videos to mp4 . Here’s what i have used :-

    1. ffmpeg -i input.avi -acodec libfaac -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

    2. ffmpeg -i input.avi -c:v libx264 -b:a 128k -vcodec mpeg4 -b:v 1200k -flags +aic+mv4 output.mp4

    Above two are working perfectly, they have succesfully converted the video. But when i run them on browser in HTML5 and in new tab (Flash Player Plugin Installed), HTML5 doesn’t play it and flash player return an error message "Video can’t be played because the file is corrupt". But when i played them on KMplayer and in Window media player they are running perfectly.

    I have been to various threads in stackoverflow related to convert avi to mp4 and here i found following in one of the forum. where one of user has accepted this a correct answer but it ain’t worked out for me.

    1. ffmpeg -y -i sample.avi -b:v 1500k -vcodec libx264 -vpre slow -vpre baseline -g 30 sample.mp4

    Above argument returned me following error "File for preset ’slow’ not found".

    Following my futher searches i came across this thread ffmpeg convert mov file to mp4 for HTML5 video tag IE9. Here following argument worked perfectly and it able to convert video in such way that it is playble on browser.

    1. ffmpeg -y -i input.avi -vcodec libx264 -vprofile high -preset slow -b:v 500k -maxrate 500k -bufsize 1000k -vf scale=-1:480 -threads 0 -acodec libvo_aacenc -b:a 128k -pix_fmt yuv420p output.mp4.

    Problem i faced here was video is converted to 420p reso which quality is noty upto mark. Smaller resolution videos are been enlarged and seems pixelated

    Thus, i had to finally put up a question. I will be very obliged if someone can give a solution for above problem. I need to convert an avi video to mp4 supported by HTML5 video tag. It should able to play it on browser and during conversion of video it should maintain original audio and video quality plus resolution.

    Thanks

  • 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)

  • FFMPEG android is processing slow

    23 novembre 2015, par jpc

    I’m using https://github.com/WritingMinds/ffmpeg-android-java as my framework for FFMPEG

    I’m trying to convert an image to a video using this command

    ffmpeg -y -loop 1 -i input.jpg -strict -2 -vcodec mpeg4 -t 5 -pix_fmt yuv420p out.mp4

    It took about 32 seconds to finish the process which is very slow for my requirements.

    Is there a way to speed this up ? I’m thinking of something around 5 seconds, perhaps approximately equal to the specified length of the video

    here’s the log btw
