Revision 6253cc9279 : Speed setting review. Substantial reworking of the speed vs quality trade offs
1er octobre 2013, par Paul WilkinsChanged Paths :
Modify /vp9/encoder/vp9_encodeframe.c
Modify /vp9/encoder/vp9_onyx_if.c
Modify /vp9/encoder/vp9_onyx_int.h
Modify /vp9/encoder/vp9_rdopt.c
Speed setting review.Substantial reworking of the speed vs quality trade offs for
speed 1 and 2.In this patch I am attempting to freeze the "quality" meaning of
speeds 1 and 2 relative to speed 0 so that in future we can
better evaluate progress.I am targeting :
Speed 1 quality -5% vs speed 0.
Speed 2 quality -10% vs speed 0It is inevitable that quality will still fluctuate a little as we adjust
settings and add new features, but we will attempt to keep as
close as possible to these values. Above speed 2 things will remain
a bit more fluid for now.In this patch speed 1 is approximately 4-5x as fast as speed 0. This
is similar to before but the quality hit is a lot less. Likewise speed 2
is approximately 2x as fast as speed 1 but is similar in quality to the
previous speed 1 configuration.Also slight change to behavior of FLAG_EARLY_TERMINATE to insure
all reference frames get at least one rd test. Important for very low
variance regions.WIP :- Added a new speed level with old speed 4 becoming speed 5.
Speed 3 and 4 tradeoffs still WIPChange-Id : Ic7a38dd7b5b63ab1501f9352411972f480ac6264

Solution Merge mp3+mp4 together with FFMPEG or other
7 juin 2018, par SandyUgaleI have been working on a project where I have .mp3 and video file (.MP4). I have FFMG on my AWS server and I’m providing both to FFMPEG give me complete video file with provided audio file. Then I send this file to my AWS S3 and then fetch this video as needed in my web app.
Problem/Use Case :
If I have 10 mp3 and 10 mp4 video files then I have to wait the until it complete all videos then only I can send them on S3, so Im waiting for long as number goes up.
Can I control this ?
Solution-1 : Don’t need to wait for loop
Meaning instead of starting all merging together parallel I would like merging to be done one by one. Referencing above example
First merge of 1.mp3 + 1. Mp4= 1.mp4 (complete file) –upload s3.
Second merge of 2.mp3 + 2. Mp4= 2.mp4 (complete file) –upload s3.
Tenth merge of 10.mp3 + 10. Mp4= 10.mp4 (complete file) –upload s3.Solution-2 : send video as they ready
How I can know which video has been ready to send to s3 ?
Solution-3 : other service
Is there any other online API or services where I can pass mp3 + mp4 and give me video url simply after merging so technically video will hosted on either their platform or on my S3 doest matter.
