• Anomalie #4562 : Suite #4468 : Unification des CSS pour les boutons et les icônes

  Mais pour l’ajout là c’est bizarre on voit pas le fond, c’est un peu nul, en tout cas pour cette couleur.
  Peut-être l’inverse aussi, le retrait est plus gros que l’ajout : ça ne va pas. C’est le retrait qui devrait être en mini+link (très peu mis en avant), et l’ajout en normal, ni link, ni peut-être mini non plus.

• How to set "ch_layout" in ffmpeg 6.1 ?

  9 juillet 2024, par Steven porite

  In 6.1 Ffmpeg, it use "ch_layout" to replace the "channel_layout" and "number". The "ch_layout" is "AVChannelLayout *" type. This type is defined in channel_layout.h, some kind of "ch_layout" is defined in this file too.
If I want to use the "av_dict_set_int()" set the "ch_layout" to "AV_CHANNEL_LAYOUT_STEREO", what should I fill to the "value" ?

  


  /**
 * Macro to define native channel layouts
 *
 * @note This doesn't use designated initializers for compatibility with C++ 17 and older.
 */
#define AV_CHANNEL_LAYOUT_MASK(nb, m) \
    { /* .order */ AV_CHANNEL_ORDER_NATIVE, \
      /* .nb_channels */  (nb), \
      /* .u.mask */ { m }, \
      /* .opaque */ NULL }

/**
 * @name Common pre-defined channel layouts
 * @{
 */
#define AV_CHANNEL_LAYOUT_MONO              AV_CHANNEL_LAYOUT_MASK(1,  AV_CH_LAYOUT_MONO)
#define AV_CHANNEL_LAYOUT_STEREO            AV_CHANNEL_LAYOUT_MASK(2,  AV_CH_LAYOUT_STEREO)
#define AV_CHANNEL_LAYOUT_2POINT1           AV_CHANNEL_LAYOUT_MASK(3,  AV_CH_LAYOUT_2POINT1)
#define AV_CHANNEL_LAYOUT_2_1               AV_CHANNEL_LAYOUT_MASK(3,  AV_CH_LAYOUT_2_1)


  


  /**
 * Convenience wrapper for av_dict_set() that converts the value to a string
 * and stores it.
 *
 * Note: If ::AV_DICT_DONT_STRDUP_KEY is set, key will be freed on error.
 */
int av_dict_set_int(AVDictionary **pm, const char *key, int64_t value, int flags);


  


• Error in compiling x264 on ARM 64-bit platform

  2 septembre 2021, par yanzhang.guo

  The same x264 source code I compiled on Debian 10 (Buster) system has no problem, but I can't compile it on an ARM 64-bit platform. Why ?

  


  Maybe there is something wrong with the Makefile, but I don't know where it is.

  


  


  1. Configure

     


     ./configure --disable-asm --enable-shared  --host=aarch64-linux

platform:      AARCH64
byte order:    little-endian
system:        LINUX
cli:           yes
libx264:       internal
shared:        yes
static:        no
asm:           no
interlaced:    yes
avs:           avxsynth
lavf:          no
ffms:          no
mp4:           no
gpl:           yes
thread:        posix
opencl:        yes
filters:       crop select_every
lto:           no
debug:         no
gprof:         no
strip:         no
PIC:           yes
bit depth:     all
chroma format: all


     


  


  2. Edit file config.mak,

     


     SRCPATH=.

exec_prefix=${prefix}
bindir=${exec_prefix}/bin
libdir=${exec_prefix}/lib
includedir=${prefix}/include

CLI_LIBX264 = $(LIBX264)


     


  


  3. Make, an error occurred, details in error.

     


  


  4. Add file config.h after configure,
