WEBVTT 00:00.890 --> 00:01.100 Hey. 00:01.850 --> 00:07.700 So in this video, we are going to deal with the P.D.A fight, a kind of you can see a binary fight. 00:08.180 --> 00:12.380 And for illustration purposes, let me upload one video file. 00:13.160 --> 00:13.870 So flawed. 00:14.780 --> 00:18.100 And that is a one sample file has been kept here. 00:18.320 --> 00:22.370 Let me open this file and I will show you what is there inside this file. 00:23.180 --> 00:30.500 So let me open with this head of economic read and you can see it has just a two page and a very simple 00:30.500 --> 00:31.550 tax has been written. 00:31.910 --> 00:37.300 So sometimes the data is available as a part of such a kind of very close form format. 00:38.240 --> 00:41.870 And this is a proprietary format by this Haddo corporation. 00:42.530 --> 00:44.070 So let me upload this simple. 00:44.120 --> 00:45.170 Not really a file. 00:45.840 --> 00:46.160 OK. 00:47.150 --> 00:47.540 All right. 00:47.990 --> 00:54.130 Now, to read this and playing with this file from the python, we are going to use the library by PDAF 00:54.140 --> 00:55.930 to let us important. 00:56.170 --> 00:59.630 And let's check whether this library's available or not. 01:01.140 --> 01:03.180 By p e f. 01:04.740 --> 01:05.140 Let's. 01:06.640 --> 01:14.440 And you can see that it came like module, not phone data, so we can easily install it with Delp installation 01:14.890 --> 01:19.120 and to execute all those cell scribbly. 01:19.180 --> 01:22.690 Well, come on, you have to start with the explanation, Mark. 01:23.710 --> 01:25.510 They installed. 01:27.590 --> 01:32.580 Q Space and I thank you by EDF. 01:34.010 --> 01:40.190 So it will download this by Pudi of two package from the central repository and install on a local machine. 01:43.200 --> 01:44.430 Now, let's do the same thing. 01:44.990 --> 01:52.410 We are going to import this by PDAF to as let's say. 01:54.150 --> 01:58.100 Saada Cronin was named Space Will Give like a PDAF. 02:00.880 --> 02:03.070 Next, this same simple dot video file. 02:03.120 --> 02:04.120 We are going to read it. 02:05.050 --> 02:14.470 So we are just going to create a 5.0 and those file points will be creating from this open function. 02:15.040 --> 02:18.190 So let me give the name like sample. 02:20.060 --> 02:20.750 Not PDA. 02:21.700 --> 02:26.900 And I want to open this particular file into binary Villamor. 02:27.410 --> 02:31.400 So no more in this case, one V, a simple remote. 02:31.550 --> 02:36.440 But it will be a hot beat that indicates that this is the binary file. 02:38.430 --> 02:39.940 Hopes it will be open. 02:41.940 --> 02:47.040 Let me assign it to some failed pointer file object file, very bad. 02:49.820 --> 02:54.870 If you see the type of this file video, it won't be like a tax. 02:54.930 --> 02:55.680 Are you a rapper? 02:56.220 --> 02:57.710 We got it. 02:58.290 --> 03:03.150 It is a more friendly to because here we are dealing with the binary file. 03:04.320 --> 03:06.090 Now, let's read this fine. 03:06.210 --> 03:11.190 So for reading purposes, we are going to use this PDAF not. 03:13.330 --> 03:14.850 BDA file that he. 03:15.980 --> 03:24.000 And let me posit this fight point objects, let's say PDAF on this, quote it. 03:25.320 --> 03:27.990 So it will return as this EDF. 03:29.720 --> 03:32.910 By pdaf to over you, very the kind of objects. 03:34.040 --> 03:39.960 Let's say we want to know how many total number of pages are there inside this video of the object. 03:40.670 --> 03:42.400 So we can just simply use, like. 03:44.340 --> 03:48.180 Numb piece on this PDA for that. 03:48.700 --> 03:49.760 So that will be a two. 03:49.980 --> 03:52.640 That means there are total two pages available. 03:54.690 --> 03:58.260 Let's say if you want to grab the content of very a speech. 03:59.940 --> 04:02.780 So we can use PDAF in the school that he did. 04:03.390 --> 04:09.600 Now this is a central object and to this object on Libya are going to get all those main information 04:09.630 --> 04:12.090 associated with this Arab ruler file. 04:12.570 --> 04:14.390 And all those my information also. 04:15.450 --> 04:16.410 So let's say get. 04:17.750 --> 04:21.780 There will be lots of gang related trails that that get paid. 04:21.860 --> 04:26.870 We are going to use it and to get which particular page number you want to read. 04:26.970 --> 04:27.170 Right. 04:27.740 --> 04:30.140 So you can use it like zero. 04:30.410 --> 04:33.710 So zero indexing here refers to a very first page. 04:34.880 --> 04:35.480 Page one. 04:36.590 --> 04:40.760 Let's put into what is there inside this page one. 04:41.770 --> 04:42.190 All right. 04:42.230 --> 04:45.590 So you can see it's kind of like snooty kind of objects. 04:47.230 --> 04:53.590 Suppose we want to grab what is the text inside this page one, page one not. 04:54.820 --> 04:57.150 We can use, like extract tax. 05:00.120 --> 05:08.040 And let me add any and you can see exit the same tax or what is written inside this, a fight we help 05:08.230 --> 05:09.960 write the same way. 05:09.990 --> 05:12.170 You can grab the page, too, or so. 05:13.110 --> 05:14.820 So, yeah, that's cool. 05:16.040 --> 05:18.780 You did not get. 05:20.910 --> 05:21.410 Speech. 05:22.000 --> 05:22.990 Let's hear first one. 05:24.630 --> 05:26.760 And beach to. 05:27.890 --> 05:30.860 Not extract X. 05:33.750 --> 05:35.880 So this is the Texel Beach to. 05:37.690 --> 05:39.930 All right, so let us close this fight now. 05:41.660 --> 05:45.630 So all those reading related information, we help Danny. 05:48.170 --> 05:53.130 Now, let's see how well we can get right into some kind of pdaf fine. 05:53.870 --> 05:54.530 So far that. 05:55.660 --> 05:58.120 We hope to create a media for that object. 05:59.200 --> 06:08.110 So that will be a right writer variable will be created from PDA stored PDA writer. 06:11.370 --> 06:11.840 All right. 06:12.710 --> 06:13.040 Now. 06:14.180 --> 06:19.940 Let's say inside this PDAF, right, that we are going to add a very first page. 06:20.180 --> 06:26.430 What we have created so this first page we got from this sample DOT P.D.A, fine. 06:27.080 --> 06:29.680 So same page we can edit here also. 06:30.060 --> 06:33.710 So like add pages or one matter, these are relevant. 06:34.340 --> 06:35.740 And we can pass on here. 06:36.260 --> 06:37.190 Page one. 06:37.820 --> 06:38.870 Let me run it. 06:39.410 --> 06:45.260 Now let's open one file a right binary more so that will be open. 06:46.310 --> 06:47.540 Let's say new. 06:48.050 --> 06:50.760 Simply not to DFI. 06:51.390 --> 06:54.590 And I want to open it in to write more. 06:54.830 --> 06:56.640 And this is the binary file. 06:56.690 --> 06:59.050 So it will be a WB, right. 06:59.150 --> 06:59.810 Binary more. 07:02.090 --> 07:08.270 Let me say to some of it, one classmate, our idea really of file. 07:10.460 --> 07:11.020 And No. 07:12.860 --> 07:14.530 We can use video writer. 07:16.890 --> 07:17.150 Right. 07:17.510 --> 07:25.920 Matter and where we're going to light it so everything will be returned to this output file stream. 07:27.130 --> 07:38.710 Let me run it and let's just close this output, not close, because when something got written, you 07:38.710 --> 07:40.060 have to close that file. 07:40.170 --> 07:40.420 So. 07:41.740 --> 07:44.190 All right, now, let's just verify from here. 07:44.750 --> 07:48.430 And you can see another file, but a new one, this goes empl. 07:49.100 --> 07:49.850 Just click on it. 07:51.690 --> 07:53.700 And open with this economic read. 07:54.960 --> 08:03.060 And you can see new file, new unnice coast sample or PDA got created and now you'll be able to observe 08:03.060 --> 08:09.690 that it has just a one page because the same one page we have extricated from this simple DOT PDA file 08:10.050 --> 08:13.960 and we'll just return inside this new underscore separate. 08:13.970 --> 08:14.810 OK, PDA, fine. 08:15.750 --> 08:16.110 All right. 08:16.500 --> 08:23.970 So that is how if the data available in some kind of textual format and those data is available in such 08:23.970 --> 08:32.370 a kind of close form format of PDA format, you can use this by PDA to library and you can deal with 08:32.370 --> 08:33.350 this text. 08:34.400 --> 08:34.770 All right. 08:35.020 --> 08:36.210 Let's all about this video.
