I've got the following error message when opening an .avi file with VirtualDub 1.10.4 on Win7:
| QUOTE | | Couldn't locate decompressor for format 'RV24' (unknown) |
Background information: The video file was created by VLC's record function while grabbing directly from some video capture device. The video file can be played in VLC flawlessly. The media info says the codec is "24 bits RGB (RV24)".
I suppose that the .avi file is using some unusual raw video format. However, I couldn't find any codec for 'RV24'. I have already tried ffmpeg-tryout.
Any suggestions?
Thanks and best regards,
rotbart |

Since nothing seems to decode it (I tried), I would use VLC to convert it to...
* MP4/H264/AAC for viewing, or
* AVI/M-JPEG/WAV for editing (use max MJPEG bitrate, 9999 kbps) |

Open the file in any HEX-editor. Replace 'RV24' at the beginning of the file to zero and save the file. Then open the file in VirtualDub.

Amazing, it works! Thanks! Although the image is flipped vertically for some reason, but it's easy to fix within VirtualDub.
So it seems the FOURCC code was wrong. I already tried several RGB FOURCC codes (http://www.fourcc.org/rgb.php), but only those which you can enter into VirtualDub, so I didn't try the 00 00 00 00 code.  |
