Basically, I want to extract burnt-in subtitle from a movie ,which is mp4. I am very new with this stuff, So I got SubRip and AviSynth and converted the movie in .avi , but when I try to open it with SubRip I get this
"LoadPlugin("d:\data\dgdecode.dll")
DirectShowSource("C:\UniConverter\Converted\bzc50.avi", 23.976, true,
false, true) ConvertToRGB24()
Then I down. AviSubDetector ,but then I got
"
error in FrameOpen- Conversion to RGB24 not available. Check that you
have required codec installed" .
So I don't know exactly what are those required codec but I google it ffms2 and dgmpgdec. I don't know how to do this 'cuz I can't find anything on google, so maybe you guys can help me do this.
Thx all <3

I'm doing something fairly simple with videojs. I simply want to set the time to an arbitrary point on the timeline by clicking on an externally build UI (not the default seek stuff, but a set of divs that are acting like a progress bar.)
All the documentation and every post seems to indicate that setting currentTime as in object.currentTime(time) works. But in my case it doesn't. Not in the console, not anywhere.
Here's my code:
function clearSetTimeBug(videoObj,timeToSetTo){
console.log('timeToSetTo:'+timeToSetTo);
console.log("-1."+videoObj.id()+" readyState(): "+videoObj.readyState());//returns 4 (loaded)
console.log("0."+videoObj.id()+" bufferedEnd(): "+videoObj.bufferedEnd());//returns about 2 seconds ahead of where the playhead is)
if(videoObj.bufferedEnd()>timeToSetTo){
console.log("1."+videoObj.id()+" currentTime(): "+videoObj.currentTime()); // returns a valid videojs object id and then shows the currentTime to be where the video's current timecode as a float.
videoObj.currentTime(timeToSetTo);//this should totally work!
console.log("2."+videoObj.id()+" currentTime(): "+videoObj.currentTime());// shows that the current time is 0!
}else{
//I added this to just go to as far as it's buffered, but this doesn't work either
console.log("3."+videoObj.id()+" currentTime(): "+videoObj.currentTime());
console.log("4. newTime: "+videoObj.bufferedEnd());
videoObj.currentTime(videoObj.bufferedEnd());
pageTime=videoObj.bufferedEnd();
console.log("5."+videoObj.id()+": "+videoObj.currentTime());// still shows that the current time is 0!
console.log("6. pageTime:"+pageTime);
}
}
The player is spun up like this:
function setUpPlayers(playerId,playlist,local_file,index){
let myAspectRatio=heightRatio+":1"
let videoTag="";
videoTag +="<video id='playerInstance"+index+"' class='video-js vjs-fluid' width='100%' height='100%'>\n";
videoTag +="\t<source src='"+playlist+"' type='video/mp4'>\n";
videoTag +="</video>\n"
$('#player'+index).html(videoTag);
window["vjPlayer"+index]=videojs("playerInstance"+index, {"autoplay": false, "preload": "auto" });
}
Play() and pause() and even currentTime() to get the current time works. But trying to set it just forces the player to go back to 0.
I'm working in a Mac in Chrome Version 86.0.4240.80 and Firefox Developer's Edition 71.0b1 (64-bit). These are all local files and I'm running it from http://localhost:8000/index.php.
In the video.js github channel, I figured out the answer to this question. I hadn't checked it on my server, so running the page locally screwed up the ability to click around and set currentTime. Quite strange, actually. I'm still not sure why it happens. You can see the comment here: https://github.com/videojs/video.js/issues/6900
Not the smartest move on my part, but hopefully this might help someone else in the future.
If you know smth about this theme please leave a comment. I am trying to get pdf file from docx using phpoffice/word. But i cant make it real because for whole day testing i get only this error:
PHP Fatal error: Uncaught exception 'PhpOffice\PhpWord\Exception\Exception' with message 'PDF rendering library or library path has not been defined.
Please don't tell me to look this question in www, i tried - nothing helpful. My code:
require './vendor/autoload.php';
require './vendor/phpoffice/phpword/bootstrap.php';
$filename = 'example';
echo PHPWORD_BASE_DIR . '/TCPDF-master';
$wordPdf = \PhpOffice\PhpWord\IOFactory::load("./file_to_fill/ДКП квартира физики.docx");
$rendererName = \PhpOffice\PhpWord\Settings::PDF_RENDERER_TCPDF;
$rendererLibrary = 'TCPDF';
$rendererLibraryPath = dirname(__FILE__).'/'. $rendererLibrary;
\PhpOffice\PhpWord\Settings::setPdfRendererPath($rendererLibraryPath);
\PhpOffice\PhpWord\Settings::setPdfRendererName('TCPDF');
$pdfWriter = \PhpOffice\PhpWord\IOFactory::createWriter($wordPdf , 'PDF');
if (file_exists($filename.".pdf")) unlink($filename.".pdf");
$pdfWriter->save($filename.".pdf");
I know that my problem is library, but i really can't understand where the file of this library is. May be it happens because today for the first time i was trying to work with composer. I tried different library like dompdf and TCPDF and my be some others.
So if you have any ideas welcome.=)
So after many hours of searching and testing i got the working code. May be i am not only one need this.
For TCPDF library:
define('PHPWORD_BASE_DIR', realpath(__DIR__));
require './vendor/autoload.php';
require './TCPDF-master/tcpdf.php';
$PdfPath = realpath(PHPWORD_BASE_DIR . '/TCPDF-master');
\PhpOffice\PhpWord\Settings::setPdfRendererPath($PdfPath);
\PhpOffice\PhpWord\Settings::setPdfRendererName('TCPDF');
$phpWord = \PhpOffice\PhpWord\IOFactory::load('yourtemplate.docx');
$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord , 'PDF');
$xmlWriter->save('result.pdf');
For mpdf library:
define('PHPWORD_BASE_DIR', realpath(__DIR__));
require './vendor/autoload.php';
require './vendor/mpdf/mpdf/mpdf.php';
$PdfPath = realpath(PHPWORD_BASE_DIR . '/vendor/mpdf/mpdf');
\PhpOffice\PhpWord\Settings::setPdfRendererPath($PdfPath);
\PhpOffice\PhpWord\Settings::setPdfRendererName('MPDF');
$phpWord = \PhpOffice\PhpWord\IOFactory::load('temp.docx');
$xmlWriter = \PhpOffice\PhpWord\IOFactory::createWriter($phpWord , 'PDF');
$xmlWriter->save('result.pdf');
But the the domPDF doesn't work at all(
So this two libraries works but not good, one of it gives me "???" when i input the Russian text. And both of them gives a lot of different free space in document (may be margin). And i can't understand how edit it.
how can I get metadata of a pdf document(e.g. title, author, creation date etc) by using mupdf library? There is not enough documentation to find out this functionality. Comments are not sufficient, too. Most probably, there is a functionality for this purpose but it is hard to find under these circumstances. The following code is what I have so far.
char info[64];
globals *glo = get_globals(env, thiz);
fz_meta(glo->doc, FZ_META_INFO, info, sizeof(info));
I have used FZ_META_INFO tag, but it doesn't work. I didn't get any info, just empty. I have checked that it has metadata. Any help is appreciated.
EDIT:
Target Android sdk:20
Min Android sdk:15
Mupdf version: 1.6
ndk: r10c
Development OS: Ubuntu 12.04
In what sense 'doesn't work' ? Throws an error ? Crashes ? Are you certain the PDF file you are using has any 'Info' metadata ?
What is the version of MuPDF ? What platform are you using ?
You need to set the relevant key in the buffer you pass to fz_meta before you call fz_mets, I notice you aren't doing that.
See win_main.c at around line 487, after you get past the macro this resolves to
char info[256]
sprintf(info, "Title");
fz_meta(doc, FZ_META_INFO, info, 256);
On return 'info' will contain the metadata associated with the Title key in the dictionary.
When in doubt, build the sample app and follow it in a debugger......
If the proper casting allow to send the key,
this casting is NOT correct to receive back a char*.
Exemple;
Proper casting to send a request
char buff[2048];
strcpy(buff,"CreationDate")
if (fz_meta(ctx,doc,FZ_META_INFO,&buff,2048)) {
buff[0] = 0;
}
Will:
find the key,
convert utf8
then will crash when copyback of the result
Proper casting to receive a request
char buff[2048];
strcpy(buff,"CreationDate")
if (fz_meta(ctx,doc,FZ_META_INFO,buff,2048)) {
buff[0] = 0;
}
Will crash during dict scanning.
looks really like a bug!
I confirm that modifying original source
info = pdf_dict_gets(ctx, info, (char *)ptr);
is the way to go. (even if strange that nobody else find it while writing code, because Meta are useful features frequently used
I started to deal with ffmpeg API ( not the command prompt ) to build a movie editor, and I'm trying to find a good tutorial about how to extract keyframes from video, but I didn't find it.
Someone did it before and can write the code here?
Someone has a good tutorial about ffmpeg API?
Thank you!
In your demuxing loop, check for the AV_PKT_FLAG_KEY flag in AVPacket::flags after calling av_read_frame() with your AVFormatContext and confirming the read packet is from the correct stream of the input. Example:
AVPacket packet;
if (av_read_frame(pFormatCtx, &packet) < 0) {
break;
}
if (videoStream/* e.g. 0 or 1 */ == packet.stream_index) {
if (packet.flags & AV_PKT_FLAG_KEY) { //do something
Note that, in my experience, you sometimes need to decode up to 2 keyframes before the desired frame in order to produce a good picture.
See the doc/examples directory in the ffmpeg distribution for some API usage examples, e.g. demuxing_decoding.c. You can also reference ffmpeg.c (the source of the famous CLI) if you are brave and/or have a good IDE.
There were some language problems in my site which uses a specific theme so I thought,I should pick out the language pack edit and reload it. Because I couldn't find a way to edit it using browser on admin panel.
I just pressed a button named export language packet. I don't know if something happened that time. But it didn't give me a file (an exported file I mean) . So I didn't do anything else. But since that time I can't reach my admin panel. While I write the URL it shows me a big white screen.
On the other side the site itself (not admin panel) is reachable. What can I do to fix my problem?
Hi,
This is the error
( ! ) SCREAM: Error suppression ignored for

The error you got is in your translation file in file translations\tr\admin.php on line number 586.
To fix that error, take a backup of that file, i.e. keep a copy of that file in some other place, then try to find out the syntax error you got there. It is some kind of PHP syntax error there in that translation file. As the translation file is only for the admin section, therefore your site front end may be fine and your site admin section is not working.
If you are not able to find that error and fix it, then delete all contents from that file, and then try to load the admin section.
You should use a translation pack which is provided by prestashop, ie download it from the prestashop http://www.prestashop.com/en/translations .
Also if you want to edit translations, use admin. In your question you mentioned, that you were not able to edit translations, please do provide details for that problem, and also try to edit translations while keeping error reporting on, so if there is any problem, you will get the errors printed. If you got errors printed, then update your question with that error message.
Let me know if you still got any questions.
