Description
When using FFmpegFrameGrabber with a wifi camera, the images can have lots of artifacts. here's an example:
this is the code I am using
FFmpegLogCallback.set()
log("attempting connection to $url")
val grabber = FFmpegFrameGrabber(url)
grabber.imageHeight = 480
grabber.imageWidth = 848
grabber.format = "rtsp"
grabber.videoCodecName = "h264_mediacodec"
grabber.frameRate = 30.0
grabber.sampleRate = 30
grabber.start()
while (alive) {
val frame = grabber.grabImage()
showPreview(frame)
}
I'm wondering if there are any tweaks that can clean the video up a bit / handle missed packets better? Specifying TCP with
grabber.options["rtsp_transport"] = "tcp"
makes the image cleaner but I am running into another issue where the video stops after 30 seconds: https://github.com/bytedeco/javacv/issues/2218
