    Added a speed feature "allow_skip_recode"

    This commit added a speed feature to make the logic of calculating
    skip_recode on a block level more explicit. This also enable the
    feature to be enabled at speed 5 where the previous logic is too
    conservative, help gain back the lost speed for —rt(-5).

  • Why can't I set "aspect ratio" by ffmpeg -aspect ? [on hold]

    7 août 2014, par yasi

    I want to generate an h264 (avc) file by a jpg file. I generated it by command :

    • ffmpeg -f image2 -i img%d.jpg -vcodec libx264 sample.h264
    • mv avatar.h264 sample-320.avc

    the img%d.jpg is 0.jpg, 1.jpg, 2.jpg ... 24.jpg, all of which is the same, resolution is 320x180

    When sample.avc is generated, I checked information of it by ESEyE, it’s like below.
    enter image description here

    As you can see, the resolution is correct, but aspect ratio is weird since original jpg sequence is 320x180, whose aspect ratio is 16:9. So, I tried to keep 16:9 by the command below

    • ffmpeg -r 25 -f image2 -i img%d.jpg -vcodec libx264 -profile:v baseline -level:v 1.1 -aspect "16:9" sample.h264

    However, it doesn’t work, the generated avc aspect ratio is still 5x3.

    How can I keep aspect ratio of 16:9 ?

    P.S.
    I guess h264 miminal block is 16x16, and avc width could be padded as 192 (16 * 12), so aspect ratio is 320:192 = 5:3.
