Allow reading of growing avi files (currently being written)
5 décembre 2014, par Joakim PlateAllow reading of growing avi files (currently being written)
This uses the RIFF header stored size to figure out the expected AVI
file size, instead of the actual file. To work fully it requires handling
failed avio_seek() instead of assuming they always succeed.Some fate file has been cut off and contains half a frame at the end which
previously was not output during demuxing. This frame is now output to
encoder, thus the fate diff update.Bug-Id : 261

Making a video with opencv and ffmpeg. How to find the right color format ?
19 décembre 2014, par lucI have a webcam video recorder program built with python, opencv and ffmpeg
It works ok except that the color of the video is more blue than the reality. The problem seems to come from color format of images.
It seems that OpenCv is giving BGR images and ffmpeg+libx264 is expecting YUV420p. I’ve read that YUV420p correspond to YCbCr.
opencv has no conversion from BGR to YCbCr. It only has a conversion to YCrCb.
I have made some searchs and tried different alternatives to try converting opencv image to something that could be ok for ffmpeg+libx264. None is working. At this point, I am a bit lost and I would appreciate any pointer that could help me to fix this color issue.
