This isn't an error - it's a debug message noting that the decoder needs some system-specific initialisation to use the hardware, which is true (<http://git.videolan.org/?p=ffmpeg.git;a=blob;f=libavcodec/decode.c;h=03b9da25f9fd9932ae6b29d65dd76d67a105098c;hb=HEAD#l1482>). Whatever is going wrong must be somewhere after that. - Mark _______________________________________________ Libav-user mailing list [email protected] https://ffmpeg.org/mailman/listinfo/libav-user To unsubscribe, visit link above, or email [email protected] with subject "unsubscribe".
