Comment (by SuRGeoNix):
It seems that the initial_pool_size of the hardware frames must be + 1 (or
even more? in my case -nvidia ffmpeg v7.1- works) for AV1. Probably
related code
https://github.com/FFmpeg/FFmpeg/blob/master/libavcodec/dxva2.c#L623
/* 1 base work surface */
num_surfaces = 1;
{{{#!c
/* add surfaces based on number of possible refs */
if (avctx->codec_id == AV_CODEC_ID_H264 || avctx->codec_id ==
AV_CODEC_ID_HEVC)
num_surfaces += 16;
else if (avctx->codec_id == AV_CODEC_ID_VP9 || avctx->codec_id ==
AV_CODEC_ID_AV1)
num_surfaces += 8;
else
num_surfaces += 2;
}}}
Maybe it just requires more margin (eg +12 surfaces for safety?)
