Not sure if anything I can do about it. * Changed some internal encoder setting so it gets a bit better quality as well as better compression ratio * Updated DirectShow video device plugin so you can type in a custom resolution. 0.33a - 2012-9-06 * Fixed bug where most bitmaps were not displaying * Added Window and Region capture, renamed source to "Software Capture" * Please email me (obs.jim@gmail.com) if there are any bugs, if or if you would like to suggest new features * Please email me if there are any issues with your bitrates or unexpected lag for your upload bandwidth -- not a verified issue, but if there are, please let me know 0.32a - 2012-9-01 * Fixed a major framerate and smoothness bug with the video. Video should now be operating smoothly and at the intended framerates (that your system can support at least). Stayed up to like 5 in the morning trying to pinpoint that one * Fixed some crashes when adding sources, especially the desktop capture source. * Fixed some mic and audio related crashes, hopefully your microphones should work now * Fixed some other crashes related to x264 * Added experimental 7.1 speaker support. I don't know if my coefficients are correct as I don't know the exact math behind downmixing, so it may sound a bit off. At the very least it won't crash with that setting anymore, hopefully. If anyone can explain the correct math or help me out with properly downmixing, it would be greatly appreciated.
