java - jcodec - has anyone seen documentation on this library? -

-

i'm trying use jcodec encode bufferedimages h264 movie. haven't been able find example code anywhere.

has used library in past? haven't seen documentation, javadoc comes library contains no usage information. if have seen examples, or can provide insight please let me know.

thanks in advance

jcodec not support encoding of h.264. can use jna x264 library or ffmpeg. if choose route thread may going: how 1 encode series of images h264 using x264 c api? .

[update] of version 0.1.0 jcodec supports h.264 encoding, here's simple class can use turn sequence of images h.264 video in mp4 container: 

public class sequenceencoder {     private seekablebytechannel ch;     private picture toencode;     private rgbtoyuv420 transform;     private h264encoder encoder;     private arraylist<bytebuffer> spslist;     private arraylist<bytebuffer> ppslist;     private compressedtrack outtrack;     private bytebuffer _out;     private int frameno;     private mp4muxer muxer;      public sequenceencoder(file out) throws ioexception {         this.ch = nioutils.writablefilechannel(out);          // transform convert between rgb , yuv         transform = new rgbtoyuv420(0, 0);          // muxer store encoded frames         muxer = new mp4muxer(ch, brand.mp4);          // add video track muxer         outtrack = muxer.addtrackforcompressed(tracktype.video, 25);          // allocate buffer big enough hold output frames         _out = bytebuffer.allocate(1920 * 1080 * 6);          // create instance of encoder         encoder = new h264encoder();          // encoder data ( sps, pps ) stored in special place of         // mp4         spslist = new arraylist<bytebuffer>();         ppslist = new arraylist<bytebuffer>();      }      public void encodeimage(bufferedimage bi) throws ioexception {         if (toencode == null) {             toencode = picture.create(bi.getwidth(), bi.getheight(), colorspace.yuv420);         }          // perform conversion         (int = 0; < 3; i++)             arrays.fill(toencode.getdata()[i], 0);         transform.transform(awtutil.frombufferedimage(bi), toencode);          // encode image h.264 frame, result stored in '_out' buffer         _out.clear();         bytebuffer result = encoder.encodeframe(_out, toencode);          // based on frame above form correct mp4 packet         spslist.clear();         ppslist.clear();         h264utils.encodemovpacket(result, spslist, ppslist);          // add packet video track         outtrack.addframe(new mp4packet(result, frameno, 25, 1, frameno, true, null, frameno, 0));          frameno++;     }      public void finish() throws ioexception {         // push saved sps/pps special storage in mp4         outtrack.addsampleentry(h264utils.createmovsampleentry(spslist, ppslist));          // write mp4 header , finalize recording         muxer.writeheader();         nioutils.closequietly(ch);     }      public static void main(string[] args) throws ioexception {         sequenceencoder encoder = new sequenceencoder(new file("video.mp4"));         (int = 1; < 100; i++) {             bufferedimage bi = imageio.read(new file(string.format("folder/img%08d.png", i)));             encoder.encodeimage(bi);         }         encoder.finish();     } }

[update 1] use code convert interleaved yuv 4:2:0 byte array jcodec picture: 

byte[] input = ... picture output = picture.create(width, height, colorspace.yuv420); int[] d0 = output.getdata()[0], d1 = output.getdata()[1], d2 = output.getdata()[2];  for(int = 0, j0 = 0, j1 = 0, j2 = 0; < input.length; += 6, j0 += 4, ++j1 , ++j2) {     d0[j0    ] = input[i    ] & 0xff;     d0[j0 + 1] = input[i + 1] & 0xff;     d0[j0 + 2] = input[i + 2] & 0xff;     d0[j0 + 3] = input[i + 3] & 0xff;      d1[j1    ] = input[i + 4] & 0xff;     d2[j2    ] = input[i + 5] & 0xff; }

on website user have 1 group. , user can change group. it's made user.groups.clear() and user.groups.add(new_group) but it's not efficient, because there 2 sql query: delete, insert. how can change group update query? user , group related each other using manytomanyfield . means intersection table exists relating both entities, , if don't specify model map (using through attribute) django creates 1 you. looking @ sources django.contrib.auth.models see that's case. fortunatly, can access intermediary model using through attribute of manager (in case, user.groups.through ). can use regular model. example: >>> alice = user.objects.create_user('alice', 'alice@example.com', 'alicepw') >>> employee = group.objects.create(name='employee') >>> manager = group.objects.create(name='manager') >>> alice.groups.add(employee) >>> alice.groups.all() [<group: employee...

i need set custom soap header attribute on jax-ws generated webservice client. case webservice calls must go through proxy server requiring specific token (recieved web request header) present in soap request header. e.g.: 1 carserviceservice service = null; 2 service = new carserviceservice(new url(url), new qname(qname); 3 carserviceendpoint port = service.getcarserviceport(); it seems in line 3 wsdl retrieved , call fails due missing security token. 1 point direction on how done? a detailed example has been mentioned here: creating , deploying jax-ws web service on tomcat 6 this article shows how create , use security token .
