  • ffmpeg : add a data size threshold for muxing queue size

    15 octobre 2020, par Jan Ekström
    ffmpeg : add a data size threshold for muxing queue size

    This way the old max queue size limit based behavior for streams
    
where each individual packet is large is kept, while for smaller
    
streams more packets can be buffered (current default is at 50
    
megabytes per stream).
    

    For some explanation, by default ffmpeg copies packets from before
    
the appointed seek point/start time and puts them into the local
    
muxing queue. Before, it getting utilized was much less likely
    
since as soon as the filter chain was initialized, the encoder
    
(and thus output stream) was also initialized.
    

    Now, since we will be pushing the encoder initialization to when the
    
first AVFrame is decoded and filtered - which only happens after
    
the exact seek point is hit as packets are ignored until then -
    
this queue will be seeing much more usage.
    

    In more layman's terms, this attempts to fix cases such as where :

    - seek point ends up being 5 seconds before requested time.

    - audio is set to copy, and thus immediately begins filling the
    
  muxing queue.

    - video is being encoded, and thus all received packets are skipped
    
  until the requested time is hit.

  • Slow Video play in mobile devices

    5 novembre 2015, par Rahul Chipad

    i have implemented video play functionality using html5 video tag.In web video play instantly but in mobile it takes to 15-20 seconds to play video over 3g/Wifi network

    i have searched for this issue and tried partial content request script in php but partial content request not working in browser.
    we have using ffmpeg for video encoding and akamai as cdn.

    ffmpeg -i '20102707.mp4' -y -f mp4 -vcodec libx264 -pix_fmt yuv420p -vprofile baseline -preset slow -b:v 158035 -r 12/1 -vf "scale=480:trunc(ow/a/2)*2" -acodec libfaac -b:a 18320 -ar 16000 -ac 2 '20102707_VIDEO_MEDIUM_H264.mp4' 2>&1

    i have tired different bit rate and frame rate for video encoding but all taking more time to play

    Any idea ?
