![]() ![]() If Viseron gets stuck on an error that you believe is not fatal, you can add a subset of that error to ffmpeg_recoverable_errors. Viseron always performs a sanity check on the FFmpeg decoder command with -loglevel fatal. Sometimes FFmpeg prints errors which are not fatal, such as error while decoding MB 0 12, bytestream 114567. You can list all available ones using the configure option 'list-indevs'. ![]() When you configure your FFmpeg build, all the supported input devices are enabled by default. If you specify all of width, height, fps, codec and audio_codec, Viseron will not need to call FFprobe and startup will be significantly faster. Input devices are configured elements in FFmpeg which enable accessing the data coming from a multimedia device attached to your system. To circumvent this you can manually specify all these options. Some cameras dont play nice with this and fail to report some information. Viseron needs to know the width, height, FPS and audio/video codecs of your stream.įFprobe is used on initialization to figure all this information out. because the output pattern is bad for a continuous stream of images.The config example above would give you two streams, available at these endpoints: However this - understandably - results in the error message: Could not get frame filename number 2 from pattern '/tmp/stream/pic.jpg'Īv_interleaved_write_frame(): Input/output error What I tried was the following: ffmpeg -f video4linux2 -r 10 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 /tmp/stream/pic.jpg In the hopes of speeding it up, I want to use a single ffmpeg command which continuously updates the. This works great, but is very slow (~1 fps). I wrote a bash script that continuously captures a frame from the webcam and puts it in /tmp/stream: while trueįfmpeg -f video4linux2 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 -vframes 1 /tmp/stream/pic.jpg jpg file from /tmp/stream and outputs it via http onto a website, so I can stream whatever is in that folder through a web browser. I have installed ffmpeg and mjpeg-streamer. ![]()
