If you have a low bandwidth I recommend compression of the video stream: ssh USER@REMOTEHOST ffmpeg -an -f video4linux2 -s 640x480 -i /dev/video0 -r 10 -b:v 500k -f matroska - | mplayer - -idle -demuxer matroska where -an turns of audio encoding. If you want audio, replace -an with -f alsa -ac 1 -i hw:3 (where hw:3 could also be hw:0 or hw:1, … See ...
You can write it in your ~/mplayer/config : stop-xscreensaver=1 And remove the following line: heartbeat-cmd="xscreensaver-command -deactivate"
On LWN, there is a Grumpy editor series, and our esteemed editor there has reviewed video editing a few times. Dated, but perhaps worth a look.
Try Kdenlive It allows for multi-track editing, audio & video layers, and has some effects. There is also Avidemux, which is more complicated, and Openshot Video Editor.
Thanks to Warren for informing me about the mediainfo command in his partial answer. I managed to construct a command that achieved the restoration of timestamps. It loops over the applicable files, and for each file, mediainfo reads the metadata, grep and sed select and format the timestamp, and touch applies it. for file in *.mp4; do touch -t ...
You can use MediaInfo for that: $ mediainfo my.mov | grep 'Recorded date' Recorded date : 2014-2-23T09:00:00Z Getting from that date format to a touch command should be a small matter of programming. Personally, I'd use Perl's Date::Manip module for this. It can almost cope with the above format; it requires 2-digit months with ...
There are several Intel drivers options which, if they don't work perfectly with your hardware, can cause issues like this: The big one is lvds_downclock, but it defaults to off. If you've changed that default, that's the first one to try. (It's possible some kernel versions defaulted to on, so its worth a try to force-disable it). i915_enable_fbc can ...
I found the solution searching on web, especially reading this page. For transmit video: avconv -i video.mov -c:v libx264 -f mpegts udp://184.108.40.206:1234 From any client in the lan: omxplayer udp://220.127.116.11:1234 The trick is to trasmit to the multicast group with the ip range: . from 18.104.22.168 . to 22.214.171.124 '1234' is the port used to ...
xvidcap allows you to select an area from your desktop and record it. Start it with the command xvidcap find your video at ./test-0000.mpeg by default.
you can try as mentioned here.You can record everything on the screen.
They both are used and supports different set of codecs. Even more some va-api drivers run nvdpau interfaces and vice versa. Archlinux wiki is good at explaining some basic things with its tables, even non distro specific stuff, which aplies to many distros: https://wiki.archlinux.org/index.php/VA-API https://wiki.archlinux.org/index.php/VDPAU
I'm not sure you can use mencoder to annotate video in this manner.You could however use ffmpeg to do so. Assuming your version of ffmpeg supports "drawtext" you can add timestamps to your video like so. Confirm drawtext is enabled: $ ./ffmpeg -filters|& grep drawtext T.C drawtext V->V Draw text on top of video frames using ...
For Fedora, try this. DISCLAIMER: This is mostly copy-pasted from here. I'm not really sure if this will work (I don't use Fedora), but it will help you install HAL, and maybe it will. After all, NBC would seem an appropriate place for DRM-laden Flash content to show up. Anyway, here goes: First, head to http://get.adobe.com/flashplayer/ and download ...
I had the same problem. Got it to work in Firefox in two steps: Protected flash content needs HAL to work (per below), but it has been discontinued. So you have to use 'zombie hal' found here: https://launchpad.net/~mjblenner/+archive/ppa-hal by typing add-apt-repository ppa:mjblenner/ppa-hal Otherwise, Adobe has instructions here on the issue, ...
OK then ffcast -s ffmpeg -r 15 -- -pix_fmt rgb24 out.gif I selected a region, did some vim, pressed q, got a .gif. (I ran that command in another terminal.) What happened? FFcast helps the user interactively select a screen region and hands over the geometry to an external command, such as FFmpeg, for screen recording. ffcast is the glorious ...
