Has anyone tried to include libjpeg-turbo/TurboJPEG support within virtualdub ?
I want to record 2x streams of 3K video in realtime - and this seems like a good candidate. |

Hi zcream, this library sounds interesting - although compiled-in support for it in VirtualDub is unlikely to happen. Someone would have to create a Video for Windows wrapper - that writes AVI files, since libjeg-turbo only writes images. The JPEG images *should* be muxable into an MJPEG AVI stream.
If external encoders become available in capture mode, there might be a way to use the command line cjpeg.exe: | CODE | | Virtualdub.exe > BMP sequence > cjpeg.exe > JPEG sequence > ffmpeg.exe: mux to MJPEG AVI |
But wait - why not try doing everything with command line tools? FFmpeg supports device capture:| CODE | | device > ffmpeg.exe: capture > BMP sequence on RAMdisk > cjpeg.exe > JPEG sequence > ffmpeg.exe: mux to MJPEG AVI |
However moving all that data between processes might be slow; it might be faster to do everything with ffmpeg: | CODE | | device > ffmpeg.exe: capture & write AVI |
(for max speed you may want some other codec such as FFvHuff)
...just thinking out loud here... |
