  • Set protocol-level metadata in AVFormatContext any time a packet is read.

    1er août 2014, par Andrew Stone
    Set protocol-level metadata in AVFormatContext any time a packet is read.

    If any option named "metadata" is set inside the context, it is pulled up to
    
the context and then the option is cleared.

  • 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)

  • "ffmpeg has text relocations" error in Android

    I’m building an Android video-sending application. I need the video to be compressed before being uploaded. In this case, I chose to use this Android wrapper of FFmpeg : https://github.com/hiteshsondhi88/ffmpeg-android-java

    FFmpeg error: WARNING: linker: /data/data/com.mycompany.myapplication/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

    Everything seemed fine when I compress small files (below 20 seconds), but when I tried to compress larger files, I seldom get the above error in the middle of the compression process, and the process was also terminated immediately. I need the application to be able to compress one minute video to about 20-35 MB.

    Here is the FFmpeg command I used :

    ffmpeg -y -i -codec:v libx264 -profile:v baseline -level 3.0 -b:v 2500k -minrate 2500k -maxrate 2500k -bufsize 1835k -pix_fmt yuv420p -preset ultrafast -crf 28 -codec:a copy

    Any idea on what went wrong ?
    Any kind of help would be very appreciated.
