Add a Record button to SLP

Post by stereomii »

Add a Record button to SLP

Recording a video is rather complicated in SLP 0.2.4, 06-12 correction:0.2.3, latest image.
Next steps must be performed to start/stop recording:
  • open settings menu
    (sometimes) scroll to "Recording" checkbox
    click checkbox
    scroll to "Save" button
    click button
    click screen to dismiss settings menu
And to check recorded video:
  • click "Video Records" button
    (sometimes) scroll to last recording
    click recorded file name
and to return:
  • click "back"
    click "back"
So I added a "Record" button showing and toggling recording state. Also added displaying a link the last recorded video in the same way as make photo does.

There are quite a numer of changes to make. Maybe there are better and more structured ways but this implementation works.

Basically the solution consists of replacing the stereopi logo with a new button, linked to a new javascript function "toggle_recording()" (copied for a great deal from "make_photo()". I removed the stereopi logo so it can not accidentally be hit if we toggle recording state.
toggle_recording calls /var/www/html/toggle_recording.php.
Added two images to /var/www/html/imgs: record0.png and record1.png as inactive/active state image.
Image and Image


To get consistent information aboute recording state after a refesh op the main web page a link to /run/record.png is used, loop-record.sh copies active or inactive button image here depending on recording state.

The solution presented here incorporates "Unreadeable recorded video in SLP" viewtopic.php?f=10&t=965

Step-by-step instruction (mount filesystems rw first):

step1: dowload record0.png and record1.png (from the links above), place them in /var/www/html/imgs
step2: copy record0.png to /run (via ssh in live SLP system or else you will not find /run)
step3: rename /run/record0.png to /run/record.png
step4: via ssh in live SLP cd to /var/www/html/imgs and create a symlink to record0.png: ln -s record.png /run/
step5: create new file /var/www/html/toggle_recording.php with following content:

Code: Select all

<?php
	$path = '/media/DCIM/';
	$filename = file('/run/RECFILE');


	/// Load config file
	$config_strings = file('/opt/StereoPi/config.conf');

	/// Parse config file
	$config = array();
	foreach ($config_strings as $k => $v) {
		$tmp = explode("=", trim($v));
		$config[$tmp[0]] = $tmp[1];
        	/// shell_exec("echo $tmp[0] $tmp[1] >> /media/message");
	}

	if ($config['record_enabled'] == "0") {
    		$config['record_enabled'] = "1";
		system("sudo cp imgs/record1.png imgs/record.png >> /dev/null 2>&1 &");
	} else {
		$config['record_enabled'] = "0";
		system("sudo cp imgs/record0.png imgs/record.png >> /dev/null 2>&1 &");
	}

	$config_string = "";
	foreach ($config as $k => $v ) {
		$config_string = $config_string . $k . "=" .  $v . "\n";
	}

        system("sudo killall -q sleep >> /dev/null 2>&1 &");
        system("sudo killall -q rtsp-server >> /dev/null 2>&1 &");
        system("sudo killall -q splitter >> /dev/null 2>&1 &");
        system("sudo killall -q raspivid >> /dev/null 2>&1 &");
        system("sudo killall -q gst-launch-1.0 >> /dev/null 2>&1 &");
        system("sudo killall -q nodejs index.js >> /dev/null 2>&1 &");

	$file = fopen('/opt/StereoPi/config.conf',"w");
	fwrite($file , $config_string);
	fclose($file);

	$res['status'] = $config['record_enabled'];
	///$res['filename'] = $filename;
	$res['filename'] = $filename;
	echo json_encode($res);
?>

step6: open /var/www/html/index.php
step7: add after following lines:

Code: Select all

	<body>

		<canvas id="video_canvas"></canvas>

(around line 58) the following:

Code: Select all

<!-- JV : add record button -->
                <img style="position:absolute;right:20px;top:20px;z-index:500;display:block;" id="record_icon" alt="" src="imgs/record.png" width="50" title="Toggle recording"
                    onclick="toggle_recording()" />
step8: comment-out logo_icon (around line 69)

Code: Select all

<!--		JV : remove logo icon, too much chanche to hit it accidentally if we want to toggle recording
		<div class="fw_hide" id="logo_icon"><a href="http://stereopi.com" target="_blank"><img src="imgs/stereopi_logo1.png" width="50" title="StereoPi site"></a></div>
		JV -->
step9: I added two addition fps rates in video_fps around line 213, included here to keep line numbers in this description consistent

Code: Select all

						<option>24</option>
						<option>25</option>
step10: after

Code: Select all

			$('#save_button').on('click', function() {
				.....
      			       var record_time = $("#record_time").val();
(around line 525) add:

                       // 	JV : manage recording button state
                                ///window.alert(document.getElementById("record_icon").src);
                                if (record_enabled == "0") {
                                        document.getElementById("record_icon").src = "imgs/record0.png";
                                    } else {
                                        document.getElementById("record_icon").src = "imgs/record1.png";
                                }

step11: after function make_photo()

Code: Select all

			function make_photo() {
				show_status_message('making a photo...');
                            . . . . .
					} else {
						show_status_message('failed');
					}

				});
			}

(around line 607) add:

                        function toggle_recording() {
                                //window.alert(document.getElementById("record_icon").src.slice(-5));
                                //show_status_message('toggle recording...');
                                $.post("toggle_recording.php", {

                                        }

                                        ///page_reload();

                                        if (json.status == 0) {

                                    })
                        }
step12: save index.php
step13: open \opt\StereoPi\scripts\loop-record.sh in your favorite editor
step13: after

Step 14: save loop_record.sh

Done! reboot your StereoPi and enjoy your record button.
[*]Allthough I double-checked the correct inclusion of all changed code I think you should test it out on a copy of your SD-card. At least until I get confirmation that this description indeed works and thus is complete ;)



From here I include all changed files, instead of copying you can also overwrite them if you trust me (or diff them with the originals) (:

Re: Add a Record button to SLP

Post by Realizator »

Whoa, great tutorial, thank you!
We did not yet add a record button because of the very simple reason: with the current software configuration, we have no real control of a recording process. I.e. we can initiate a record, but if this subprocess is broken, the system does not know it, and still shows you "Recording is in a process". In the updated SLP we will control this at the low level. But, with your previously suggested improvement (to avoid broken video files), your current solution can be very stable!

That is the reason why I added a link to the last recorded video after stopping recording.
At least I now have a quick way to check my recording :)

Re: Add a Record button to SLP

Post by stereomii »

There are still some minor flaws in this solution.

If StereoPi boots up with recording enabled sometimes loop_record does not read the correct date-time. Recording starts, recording status is correctly dispayed (red button) but the record-[date-time].mp4 has an old timestamp, making it difficult to find if you have a lot of recordings.

This wrong date-time could well be present in the original 0.2.3 version. I am not able to quickly check this at this moment.

Note: to change recording enabled in /boot/stereopi.conf you have to use [SAVE] in settings menu. The toggle button does not save state in /boot/stereopi.conf
