libavcodec/vaapi_decode : fix the problem that init_pool_size nb_surface
11 janvier 2022, par Wenbin Chenlibavcodec/vaapi_decode : fix the problem that init_pool_size < nb_surface
For vaapi if the init_pool_size is not zero, the pool size is fixed.
This means max surfaces is init_pool_size, but when mapping vaapi
frame to qsv frame, the init_pool_size < nb_surface. The cause is that
vaapi_decode_make_config() config the init_pool_size and it is called
twice. The first time is to init frame_context and the second time is to
init codec. On the second time the init_pool_size is changed to original
value so the init_pool_size is lower than the reall size because
pool_size used to initialize frame_context need to plus thread_count and
3 (guarantee 4 base work surfaces). Now add code to make sure
init_pool_size is only set once. Now the following commandline works :ffmpeg -hwaccel vaapi -hwaccel_device /dev/dri/renderD128 \
hwaccel_output_format vaapi -i input.264 \
vf "hwmap=derive_device=qsv,format=qsv" \
c:v h264_qsv output.264

ffmpeg -f concat -i c.txt -c copy concat.mp4



c.txt file content


ffconcat version 1.0
file first.mp4
outpoint 55000.0

it is done but takes a too long time, and during processing throws a lot of errors

I noticed that somehow it depends on file size or duration (e.g. if outpoint is 50000.0 it is ok and no errors) but I cannot get what is the exact problem.
