Description Сергей 2023-05-02 00:28:29 MSK 
OS Alt P10.1K
kernel 5.15.106-un-def-alt1

Проблема:
Для получения AVC-Intra 100 требуется формат yuv422p10le, он доступен c libx264 10-bit. По умолчанию сейчас стоит libx264-148-alt3 на 8-bit.

При попытке получить avc-intra 100.
Выдает:
    Incompatible pixel format 'yuv422p10le' for codec 'libx264', auto-selecting format 'yuv422p'
    [libx264 @ 0x556bf559f5c0]  8-bit AVC-Intra is not widely compatible
    [libx264 @ 0x556bf559f5c0] 10-bit x264 is required to encode AVC-Intra
    Error initializing output stream 0:0 -- Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height
    Conversion failed!

Простой способ проверки битности libx264.
    ffmpeg -h encoder=libx264 | grep "Supported pixel formats:"
Вывод 10 бит:
    ....
--> Supported pixel formats: yuv420p10le yuv422p10le yuv444p10le nv20le
    
Вывод 8 бит:
    ....
--> Supported pixel formats: yuv420p yuvj420p yuv422p yuvj422p yuv444p yuvj444p nv12 nv16 nv21

Я пересобрал библиотеку на 10-бит и положил ее руками в /usr/lib64/
ffmpeg отлично с ней работает.
Собирал 10 битный libx264, изменяя bit-depth. 
%configure \
  --disable-cli \
  --enable-debug \
  --enable-pic \
  --enable-shared \
  --bit-depth=(8 поменял на 10)
Предполагаю новый libx264-164-alt1 поддерживает и 8, и 10 bit.
