![]() This seems to have generated the video file properly as I was able to Seek, Forward, Rewind the Video using Windows Media Player and Exoplayer on Android. Switched Mode setting from Watch-Only to Record and entered in the Recording Settings MP4 as File Type, Copy as Video Codec, None as Audio Codec, 3 as Recording Segment Interval. Is it the same command used when traditional recording ? However, I notice that this might be the command used for the stream. Tried the command above using a different ip camera url and it seemed to work. Also just want to be sure, this command is when recording or when streaming?Ĭmd: -progress pipe:5 -use_wallclock_as_timestamps 1 -r 24 -analyzeduration 1000000 -probesize 1000000 -fflags +igndts -loglevel warning -i "rtsp://192.168.0.200:554/onvif1" -strict -2 -an -s 640x480 -q:v 15 -vf "fps=24" -an -c:v mjpeg -f mpjpeg -boundary_tag shinobi pipe:1 -vf "fps=1" -update 1 "/mnt/tmp/s.jpg" -y -s 640x480 -vf "fps=25" -an -c:v pam -pix_fmt gray -f image2pipe pipe:3 -vcodec copy -an -f hls -live_start_index -3 -hls_time 2 -hls_list_size 10 -start_number 0 -hls_allow_cache 0 -hls_flags +delete_segments+omit_endlist "/mnt/tmp/detectorStream.m3u8" Executed it via command line but got an error "Error writing trailer of pipe:3: Bad file descriptor". To try out and visualize buffered time ranges we can write a little bit of HTML: Īnd a little bit of JavaScript: window.So I got something like the following which I simply replaced "cmd:" with "ffmpeg". įor this audio instance, the associated TimeRanges object would have the following available properties: // returns 2 This represents two buffered time ranges - one spanning 0 to 5 seconds and the second spanning 15 to 19 seconds. Without any user interaction there is usually only one time range, but if you jump about in the media more than one time range can appear, as illustrated by the below visualization. This button is also available on the Latest Videos and Video Player pages, so you can always optimize videos even if you recorded them with an. You can click on the Optimize button after you recorded a video. This will allow you to navigate through the video and skip parts of it. end(index): The end time, in seconds, of a time range. You can use the Optimize video feature to make videos seekable.start(index): The start time, in seconds, of a time range.length: The number of time ranges in the object.( learn more about TimeRanges).Ī TimeRanges Object consists of the following properties: TimeRanges are a series of non-overlapping ranges of time, with start and stop times. Var bufferedTimeRanges = myAudio.buffered TimeRanges Object We can access these attributes like so: var myAudio = document.getElementById('my-audio') This will work with or for now let's consider a simple audio example: This is usually contiguous but if the user jumps about while media is buffering, it may contain holes. It returns a TimeRanges object, which will tell us which chunks of media have been downloaded. The buffered attribute will tell us which parts of the media has been downloaded. This article discusses how to build a buffer/seek bar using TimeRanges, and other features of the media API. Sometimes it's useful to know how much or has downloaded or is playable without delay - a good example of this is the buffered progress bar of an audio or video player.
