Доброго времени суток. Ситуёвина крайне мутная, отчасти ест-но по причине моей тупости... Есть китайская веб камера, вроде как full hd, однако vlc по дефолту имеет с нее 320х240, указав  show-sizw=640x360, можно немного поднять разрешение, но все равно до full hd как до китая...
Вот список поддерживаемых форматов, полученных по команде
ffmpeg.exe -hide_banner -list_options true -f dshow -i video="GENERAL WEBCAM" > b.txt 2>&1

[in#0 @ 00000245cec8f140] Error opening input: Immediate exit requested
Error opening input file video=GENERAL WEBCAM.
однако ffplay прекрасно получает с этой железяки full hd, вот вывод команды
ffprobe -f dshow -i video="GENERAL WEBCAM" > a.txt 2>&1
Input #0, dshow, from 'video=GENERAL WEBCAM':
Duration: N/A, start: 411589.936170, bitrate: N/A
Stream #0:0: Video: mjpeg (Baseline) (MJPG / 0x47504A4D), yuvj420p(pc, bt470bg/bt709/unknown), 1920x1080, 30 fps, 30 tbr, 10000k tbn
Ну и вопрос... Как заставить vlc получать с этой камеры full hd хотя бы с рук, задача максимум - получить full hd с этой камеры при помощи vlm
Заранее благодарен за любые идеи...
p.s.
ffmpeg вот такой командой
ffmpeg -f dshow -video_size 1920x1080 -i video="GENERAL WEBCAM" -c:v mpeg4 -y $out.mp4
нормально пишет в файл full hd... |
