For Y210 on big-endian hardware, it'll be defined as Y210BE in pixfmt.h: #define AV_PIX_FMT_Y210 AV_PIX_FMT_NE(Y210BE, Y210LE) And in the query of format_entries[] in utils.c, AV_PIX_FMT_Y210BE is not declared to have the capability to support Input or Output in swscale. So Y210 software scale is not going to be supported on big-endian hardware. Hence this won't break fate on big-endian hardware for Y210 IMHO, because this patch didn't declare it has the capability for either input or output support. If there is something wrong with my understanding, please correct me. Thanks. _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
