  • mediastreamvalidator. How can I validate local files

    20 juin 2012, par Agzam

    1) Is there any way to check segmented HLS files if they compliant and correct ?

    I guess mediastreamvalidator from Apple's HTTP Live Streaming Tools should do that, but when I run it against local index.m3u8, it says "Did not receive playlist".

    2) Is there any way to do stream validation on Windows ?

    3) Initially my problem was to do segmenting on Windows, after a lot of hours of searching I've found out that latest ffmpeg can do that. I'm not sure though if it creates correct HLS videos, it doesn't create .m3u8 playlists, which is not a big deal I guess, as long those segments are correct and use Access Unit Delimiter NALs and etc.

  • Making a video with opencv and ffmpeg. How to find the right color format ?

    17 mai 2024, par luc

    I 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.
