Searching uvc 1.5 compatible webcam recording software for Windows
Hi everybody,
I am searching for an alternative to the Windows 10 "Camera" app. I own a no name webcam which is uvc 1.5 compatible ( https://en.wikipedia.org/wiki/USB_video_class ) and is able to send a ready encoded h.264 stream. The only Windows software which is able to record this stream without trying to reencode it is the Windows 10 "Metro" Camera app. All other programs for Windows I could find insist in reencoding the stream, which is completly unneccessary. Under Linux, I found the program "guvcview", which is able to exactly what I want: Use the "preencoded" h.264 stream from the camera, encode the captured audio to mp3, aac or something else and then mux both streams to mkv or mp4. In addition, guvcview allows me to select the frame size, e.g. 640x480, 1280x720 or 1920x1080, and the frame rate, which must be set to 25fps, while the Windows Camera app sticks to 30fps, which is not correct for this camera. For some reason, the builtin encoder of the camera is good enough for 25fps but sometimes to "slow" for 30fps. Does one one of you have a recommendation ? With Graphstudio, I am able to record the preencoded 25fps stream, but I am hoping for a more comfortable solution. C.U. Nanobot Last edited by NanoBot; 20th October 2020 at 22:15. Reason: Corrected the program name to Graphstudio |

If guvcview allows selectable frame size and fps then it will reencode.
Which you don't want. You may upload a video stream sample to wetransfer.

No, luckily guvcview does not recode the video, using this configuration:
Code:
#Guvcview 2.0.6 config file #video input width width=1920 #video input height height=1080 #video input format v4l2_format=875967048 #video input capture method capture=mmap #audio api audio=port #gui api gui=gtk3 #render api render=sdl #video codec [raw mjpg mpeg flv1 wmv1 mpg2 mp43 dx50 h264 vp80 theo] video_codec=raw #audio codec [pcm mp2 mp3 aac ac3 vorb] audio_codec=mp3 #profile name profile_name=default.gpfl #profile path profile_path=/home/nanobot #video name video_name=my_video.mkv #video path video_path=/media/nanobot/Daten #video sufix flag video_sufix=1 #photo name photo_name=my_photo.jpg #photo path photo_path=/home/nanobot #photo sufix flag photo_sufix=1 #fps numerator (def. 1) fps_num=1 #fps denominator (def. 25) fps_denom=25 #audio device index (-1 - api default) audio_device=4 #video fx mask video_fx=0x0 #audio fx mask audio_fx=0x0 #OSD mask osd_mask=0x0 crosshair_color=0xff00 And what I am looking for is a program with the same capabilities, but for Windows 10. And until now, I could not find one. |
