FFMPEG (libx264) "height not divisible by 2"
3 octobre 2023, par Andy HinI am trying to encode a .mp4 video from a set of frames using FFMPEG using the libx264 codec.



This is the command I am running :



/usr/local/bin/ffmpeg -r 24 -i frame_%05d.jpg -vcodec libx264 -y -an video.mp4




I sometimes get the following error :



[libx264 @ 0xa3b85a0] height not divisible by 2 (520x369)




After searching around a bit it seems that the issue has something to do with the scaling algorithm and can be fixed by adding a -vf argument.



However, in my case I don't want to do any scaling. Ideally, I want to keep the dimensions exactly the same as the frames. Any advice ? Is there some sort of aspect ratio that h264 enforces ?

avcodec/aacps : Move initializing common stuff to aacdec_common.c
24 septembre 2023, par Andreas Rheinhardtavcodec/aacps : Move initializing common stuff to aacdec_common.c
ff_ps_init() initializes some tables for AAC parametric stereo
and some of them are only valid for the fixed- or floating-point
decoder, whereas others (namely VLCs) are valid for both.
The latter are therefore initialized by ff_ps_init_common()
and because the two versions of ff_ps_init() can be run
concurrently, it is guarded by an AVOnce.Yet now that there is ff_aacdec_common_init_once() there is
a better way to do this : Call ff_ps_init_common()
from ff_aacdec_common_init_once(). That way there is no need
to guard ff_ps_init_common() by an AVOnce any more.Signed-off-by : Andreas Rheinhardt <andreas.rheinhardt@outlook.com>
