  • RealTime MPEG compression

    Is there anyway I can do real time MPEG compression ?? My harddisk is running out of sapce !! If not is there a way to tweak the Zoran chip for higher compression ??

    It mainly depends on the speed of your processor. With a PIII-500+, you should be able to do it with the right software (ie Ulead Media Studio Pro 6/Video Stuido 4). Also, you may want to look at the Divx codec, I'm still playing with it early on, but I can do 352x240 in realtime with my PII-400 using the YUY2 hack.

      How do you actually capture directly to DivX? I can't seem to get any dialog box or options where to specify wich codec, I want to use for compression. Neither with the PC-VCR or AVI_IO!?! I can only capture MJPG or RGB.

      BTW: The YUY2-hack works just fine

        Well, I've been using MSP 6, but as I said in the 'Divx question' thread, I don't think MSP likes Divx much. I tried VirtualDub 1.2a, and that managed to blue screen as soon as I hit capture. AVI_IO has the best luck, but I really and displeased that it can only do PCM for the Audio.

          gibverse,

          to do mp3 audio in realtime you need to install the Radium MP3 codec... the one that comes with Media Player will not let VFW programs encode with it.

          On my P3-500 running Win98SE I capture straight to 352x240x29.97 1200kbit Divx and 128kbit mp3 using AVI_IO, the Radium MP3 codec and DivX 3.1...

          erik,

          in AVI_IO under the Video Settings menu, choose Compression and change it from No Recompression to DivX Fast Motion and that should be that....

          ted,

          I would say used DivX depending on the size that you want to capture at... DivX can be very small at times...

          hope this helps

              Eik,

              Select RGB capture type instead of MJPEG, then go to your compression formats.

              RBryant,

              Any suggestions on where to pick up the Radium MP3 codec?

                Ah, that might explain it. I thought "Capture Type" should be YUY2. I'll give it a try.

                I ran a search on Google, and found the Radium Codec (v1.263) here (882KB):

                  Ted,

                  Sounds like you need to look into "windows scripting" to setup a scheduled task and hope windows doesn't crash while waiting for the program's time to come :-)

                  There is an article in this month's PC Magazine, (May 9 issue, pgs 141-142) that might get you started.

                  If you set something up, make up an "idiots-guide" for it so others can benefit from your efforts.

                    RBryant,

                    I don't have any choices in the Video Settings menu. The only option is "No Recompression".
                    How do I fix this?

                      Changing the capture type to RGB didn't enable me to capture to Divx or Mpeg4. The only option is Indeo 5.06, and thats it.

                      It doesn't seem like the dropdown box is working properly. Maybe my driver is corrupted.

                      Any suggestions?

                        The "dropdown" box is inded broken!!
                        It takes the first videocodec in system.ini!
                        Rearange in system.ini, ie the one you want first!!

                          You are absolutely right...changing the orders of the [drivers32] in system.ini worked! Now I can capture to DivX.

                          My system can't keep up though :/
