В данный момент этот патч не принят в апстрим, и я даже не гарантирую его стопроцентную работоспособность. Код mjpg-streamer очень плохо структурирован и чрезвычайно запутан, и я мог что-то упустить. Собственно, это одна из причин, почему µStreamer написан с нуля.

|

* ```2``` Это фича позволяет в несколько раз снизить объем исходящего трафика при трансляции HDMI, однако увеличивает загрузку процессора и добавляет небольшую задержку. Суть в том, что HDMI - полностью цифровой интерфейс, и новый захваченный фрейм может быть идентичен предыдущему в точности до байта. В этом случае нет нужды передавать одну и ту же картинку по сети несколько раз в секунду. При использовании опции `--drop-same-frames=20`, µStreamer будет дропать все одинаковые фреймы, но не более 20. Новый фрейм сравнивается с предыдущим сначала по длине, а затем помощью ```memcmp()```.

|
||||
|
||||
* ```3``` Поскольку µStreamer писался в первую очередь для устройств видеозахвата, в нем реализованы только те форматы, которые для них были нужны. MJPG в контексте входных данных означает, что устройство умеет самостоятельно сжимать картинку в JPEG и отдавать ее программе, что позволяет значительно снизить загрузку процессора и избавить его от необходимости кодировать картинку софтом. Этот формат поддерживается большинством веб-камер, но не поддерживается ни одним из встреченных мной устройств видеозахвата; его не умеет ни [Auvidea B101](https://auvidea.com/b101-hdmi-to-csi-2-bridge-15-pin-fpc/), ни [EasyCap UTV 007](https://www.amazon.com/dp/B0126O0RDC). Нет никаких технических сложностей добавить поддержку аппаратного MJPG источника, но у меня просто пока не дошли до этого руки.
