  • How to batch convert mp4 files to ogg with ffmpeg using a bash command or Ruby

    3 avril 2013, par TJ Sherrill

    I am running a OSX, don't know tons about video conversions. But I have like 200 videos that are all in mp4 format and won't play in Firefox. I need to convert them to ogg to use the html5 video tag.

    These files live in a folder structure that makes it hard to do files one at a time. I would like the bash command or Ruby command to go through all child folders and find all .mp4's and convert them.

    I found one reference of how to do this with Google : http://athmasagar.wordpress.com/2011/05/12/a-bash-script-to-convert-mp4-files-to-oggogv/

    #!/bin/bash
    
for f in $(ls *mp4 | sed ‘s/\(.*\)\..*/\1/’)
    
do
    
ffmpeg -i $f.mp4 -acodec vorbis -vcodec libtheora $f.ogg
    
done

    But have no idea how to convert this from linux to osx.

  • Revision 422d7bc918 : Relax maximum Q for extreme overshoot. Added code to relax the active maximum Q

    28 octobre 2014, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_firstpass.c



    Relax maximum Q for extreme overshoot.

    Added code to relax the active maximum Q in response
    to extreme local overshoot to reduce bandwidth peaks.

    The impact is small in metrics terms, but it this helps reduce
    bandwidth spikes and overall overshoot in a number of
    clips in our tests sets (especially the YT test set).

    In particular this should help prevent very big spikes where a clip
    is mainly easy but has a short hard section. In such a case a choice
    of maximum Q for the clip as a whole may allow us to hit the overall
    target rate but give some extreme spikes. The chunked encoding in YT
    mitigates this problem but it can show up where a longer clip is
    coded as a single chunk.
