H.264 does not support more than 14bit, x264 does not support more than 10bit input. > Do you know of a codec that supports encoding a video using > AV_PIX_FMT_GRAY16BE pixel format (or anything similar)? jpegls, png, tiff, dpx, sgi, ffvhuff, ffv1 (all lossless) Jpeg2000, but FFmpeg needs the external library libopenjpeg for encoding gray16 (lossy or lossless) Carl Eugen _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
