![]() ![]() audio-desync= To preset and synchronise your audio to video, you can +/- the integer.Īudio-sync To maintain audio/video synchronisation on the fly. sout-keep Keeps your stream open and listening. Look these up in the command line help link. I recommend that you try the example methods as they are before changing everything to suit your anticipated needs.Įxample tweaks. There are any number of “tweaks” and “mods” that can be applied to the output string or command line. Method 2 can work well in single stage and usually better in two stage, but requires more cpu power.I leave it to you, the user, to experiment with what works best for you. Method 1 works well with two stage giving an improved picture quality with modest cpu usage given that the wmv codec is less than best compared with what is available. A two stage transcode on two different boxes will be less susceptible to quality problems related to mutual or random cpu activity spikes caused by other applications. A two stage transcode may offer advantages in quality at the cost of time and hardware to effect it. Single vs Two stage transcode? A single stage transcode may work well for many situations. Or in this case 25% of the original pixel area. So scale=0.5 will half original width/height in pixels. Scale=xx determines the output size relative to source size applied to width/height ratio. The smaller the image the less compression and bandwidth needed to stream.ĭeinterlace= This command useful if you are using an interlaced source. The larger the image, the better the definition, but will require more cpu power and bandwidth. Width=xx & height=xx Determines the aspect ratio and the size of the image in pixels. So lower fps will give better quality for given bandwidth. The more fps, then the smoother the moving image, however, this uses more bandwidth and compression. As above, but relates to audio.įps=xx Frames Per Second. The more compression the lower the video quality.Īb=xx Audio Bandwidth. ![]() This parameter in effect sets the target bandwidth of the output video stream and hence the compression required. The following methods and examples deal directly with the output string found in the GUI.ĭescription of command parameters used in the methods following This should help to give an insight into how to construct a complete command line and enter the appropriate parameters. ![]() I have included an example of a complete true command line with the same parameters as the Win XP example in Method 2. The following methods and examples modify the generated stream output string. The above links will give an overview of the commands available to use to manipulate and optimise the Command output string.
