Bol na svete nov\u00fd release ESP-KVM 0.51.2, otvoren\u00e9ho firmv\u00e9ru, ktor\u00fd premie\u0148a dosku na mikroprocesore ESP32-P4 na IP-KVM s pr\u00edstupom k obrazovke, kl\u00e1vesnici a my\u0161i vzdialen\u00e9ho po\u010d\u00edta\u010da cez webov\u00fd prehliada\u010d, bez potreby in\u0161tal\u00e1cie agenta na spravovanej stanici. K\u00f3d je nap\u00edsan\u00fd v jazyku C a je distribuovan\u00fd pod licenciou Apache 2.0. Hlavn\u00e1 zmena v tomto vydan\u00ed \u2014 zaznamen\u00e1vanie toho, \u010do sa deje na obrazovke cie\u013eov\u00e9ho zariadenia na kartu microSD samotn\u00e9ho zariadenia. <\/p>\n
Recording is activated by a button in the web interface and is saved in the VIDEO directory as .ts files with H.264 video. The device captures the same stream it delivers to viewers, eliminating the need for re-encoding: on the Espressif ESP32-P4 Function EV board, the frame rate during recording remained at 21-22 per second without loss when playing back video on the target machine. The .ts file can be played in VLC and mpv, and if interrupted by card removal or power disconnection, it opens up to the point of disruption. Long recordings are divided into 10-minute files and stop after an hour; both values are adjustable. An additional button saves a screenshot in JPEG format to the SCREENSHOTS folder, including when using the H.264 codec: a dormant hardware JPEG encoder is utilized for the snapshot. <\/p>\n
Stla\u010denia kl\u00e1vesov a kliknutia my\u0161ou m\u00f4\u017eu by\u0165 zaznamenan\u00e9 do s\u00faboru so titulkami .srt ved\u013ea videa \u2014 vo forme riadkov \u201eTyped: root\u201c, \u201eCtrl+Alt+Delete\u201c, \u201e\u013dav\u00e9 kliknutie (812, 440)\u201c. Predvolene zadan\u00fd text je nahraden\u00fd bodkami, ak je to potrebn\u00e9, ulo\u017e\u00ed sa v celej svojej forme. Rozlo\u017eenie sa berie z nastaven\u00ed cie\u013eovej kl\u00e1vesnice. <\/p>\n
Pridan\u00fd re\u017eim videorekord\u00e9ra, ktor\u00fd funguje na rovnakom princ\u00edpe ako automobilov\u00fd: zariadenie neust\u00e1le uchov\u00e1va posledn\u00e9 min\u00faty obrazovky a uklad\u00e1 ich spolu s nasleduj\u00facimi sekundami, ke\u010f sa nie\u010do stane \u2014 obrazovka sa zmen\u00ed na jednoliate pozadie (typick\u00e9 pre obrazovku n\u00fadzov\u00e9ho zastavenia), objav\u00ed sa sledovan\u00e1 fr\u00e1za, zhasne indik\u00e1tor nap\u00e1jania ATX, alebo oper\u00e1tor stla\u010d\u00ed tla\u010didlo. Z\u00edskan\u00e9 video je preveden\u00e9 do form\u00e1tu MP4 s kapitolami pre ka\u017ed\u00fa udalos\u0165, a pri zapnut\u00fdch upozorneniach je odoslan\u00e9 na Telegram ako prehrate\u013en\u00e9 video v chate. <\/p>\n
Minulos\u0165 je mo\u017en\u00e9 uchov\u00e1va\u0165 dvoma sp\u00f4sobmi: v opera\u010dnej pam\u00e4ti PSRAM, kde nezaber\u00e1 miesto na karte, k\u00fdm nenastane udalos\u0165, alebo na samotnej karte kr\u00e1tkymi fragmentami s odstra\u0148ovan\u00edm zastaran\u00e9ho \u2014 druh\u00fd sp\u00f4sob funguje aj na dosk\u00e1ch s rev\u00edziou \u010dipu do 3.0, kde po spusten\u00ed k\u00f3dova\u010da H.264 zost\u00e1va vo\u013en\u00e9 PSRAM pribli\u017ene 3 MB oproti 11 MB na nov\u00fdch rev\u00edzi\u00e1ch. <\/p>\n
Objavil sa re\u017eim \u010dasozbern\u00e9ho videa: jeden sn\u00edmok sa uchov\u00e1va raz za zadan\u00fd po\u010det sek\u00fand, prehr\u00e1vanie prebieha r\u00fdchlos\u0165ou 25 sn\u00edmkov za sekundu, tak\u017ee hodina pr\u00e1ce pri intervale 10 sek\u00fand sa zmest\u00ed do 14 sek\u00fand videa. Z\u00e1znamy a sn\u00edmky s\u00fa zhroma\u017eden\u00e9 v samostatnej paneli rozhrania, odkia\u013e ich m\u00f4\u017eete stiahnu\u0165, odstr\u00e1ni\u0165 a prehr\u00e1va\u0165 bez predbe\u017en\u00e9ho na\u010d\u00edtania s\u00faboru v celku: MP4 sa otv\u00e1ra \u0161tandardn\u00fdm prehr\u00e1va\u010dom prehliada\u010da, a .ts sa rozober\u00e1 na sn\u00edmky v samotnej konzole a dek\u00f3duje t\u00fdm ist\u00fdm dek\u00f3derom H.264, ako aj \u017eiv\u00fd obraz, s pos\u00favan\u00edm a zobrazen\u00edm titulkov. Na stran\u011b za\u0159\u00edzen\u00ed je implementovan\u00e1 podpora rozsahov HTTP pre pos\u00favanie. <\/p>\n
Realizovan\u00e9 vyh\u013ead\u00e1vanie textu na obrazovke. Po\u010das nahr\u00e1vania zariadenie ka\u017ed\u00e9 tri sekundy \u010d\u00edta obrazovku ako s\u00fabor znakov a ukl\u00e1d\u00e1 pre\u010d\u00edtan\u00e9 do s\u00faboru ved\u013ea videa; v paneli nahr\u00e1vania vyh\u013ead\u00e1vanie pod\u013ea fr\u00e1zy ukazuje, kedy bola na obrazovke, a prehr\u00e1va z\u00e1znam od tohto momentu. \u010c\u00edtaj\u00fa sa iba obrazovky vykreslen\u00e9 znakogenera\u010dom \u2014 BIOS, ponuka zav\u00e1dzania, in\u0161tala\u010dn\u00fd program, konzola. <\/p>\n

Hodiny zariadenia sa teraz synchronizuj\u00fa cez NTP a \u010dasov\u00e9 p\u00e1smo sa vyber\u00e1 zo zoznamu miest v nastaveniach \u2014 predt\u00fdm sa uchov\u00e1valo v sekcii, ktor\u00fa rozhranie nezobrazovalo. <\/p>\n
