  • How to greatly reduce video size before downloading while maintaining good quality ? [closed]

    25 septembre 2017, par Momin Shaikh

    I need to download huge files from YouTube with my android phone.. need to download a lot of 360p videos for my study purposes but living in a 3rd country like Bangladesh where bandwidth costs is super high forcing me to afford less data. So, I am looking for a way to greatly reduce file size still maintaining good quality.

    I know that converting videos to x265 or HEVC format reduces video sizes as well as keeping the good quality keeping . But i think that can not be done online.. Is there any way to just reduce file size without reducing the quality ?

  • Stack architecture for handling video uploadings

    18 septembre 2017, par Lunf

    I have Springboot app (on EC2 xlarge) which handle multi-part upload video from mobile apps. The average video file is 250 350MB which currently stored in local disk before ffmpeg thread is started to convert and upload to S3 then will be removed from local disk.

    The problem is the app server could not keep up with number of uploads concurrently (5 videos), and CPU, RAM is maxed out.

    My question is what is the strategies (architecture) to scale in order to handle more uploads concurrently and should I need to rewrite the app server in specific way to meet my goal, let say 50 videos.

    Thank you

  • Revision 3b2e73b9a4 : Remove tx cache and speed up tx size selection 1. The RD scores obtained during

    29 juillet 2015, par Yunqing Wang

    Changed Paths :
     Modify /vp9/encoder/vp9_context_tree.h


     Modify /vp9/encoder/vp9_encodeframe.c


     Modify /vp9/encoder/vp9_rdopt.c



    Remove tx cache and speed up tx size selection

    1. The RD scores obtained during the tx size selection were stored in the
    tx cache, and used to help make the tx decision for the following frames.
    This wasn’t used anymore in VP9 encoder. Recovered the related decision
    making code from 1.5+ years ago, and borg tests didn’t show any quality
    gain. This patch removed it to lower the complexity.

    2. An optimization was done after the above refactoring. If the tx_mode
    is not TX_MODE_SELECT, we only need to test the chosen tx size instead
    of all posible tx sizes. This gave a 1.5% average speed gain at speed 2,
    and a 1% average speed gain at speed 3.
