Previously these messages are hidden in the code, thus a warning info could be a more gentle improvement IMHO. (since there will be other error logs prompted when av_hwframe_map() fails) It sounds an error message is necessary.

Detailed message could be helpful when using hwmap=mode=direct,format=xxx for both qsv and vaapi. Signed-off-by: Linjie Fu <linjie.fu@intel.com> --- libavutil/hwcontext_vaapi.c | 9 ++++++--- 1 file changed, 6 insertions(+), 3 deletions(-)
