[FFmpeg-devel] [PATCH] lavc/cbs_av1: Add read/write flag in log message

[Jun Zhao]

From: Jun Zhao <barryjzhao at tencent.com>

Before this change, the command:

ffmpeg -y -i bear-av1.mp4 -c:v copy bear-av1.ivf -loglevel 99

always dump the log message like:

AVBSFContext @ 0x55ff99e78e00] Frame 4:  size 320x240  upscaled 320  render 320x240  subsample 2x2  bitdepth 8  tiles 1x1.
    Last message repeated 1 times

it's hard to distinguish writing or reading.
