Assertion failed on quick.js on Windows #4

Open fracnesco opened 1 month ago

fracnesco commented 1 month ago

When running this on windows:

./bin/ffgac.exe -i CEP00109_mpeg4.avi -vcodec mpeg4 -an -mb_type_script mb_type.js -f rawvideo -y NUL

export function mb_type_func(args) { console.log("glitchframe") }

I get this error:

I think I've found the bug: The call to mb_type_func (ret = ff_script_call_func(script, NULL, s->mb_type_func, func_args, NULL); in mpegvideo_enc.c) is called from a different thread from which script was created in ff_mpv_encode_init(), and quickjs does not like that.

At least that's what it seems like. But I won't have time to fix it right now :/.

Seems like I'm hitting the same error with -pict_type_script : 

ffgac -i turbo_killer_trimmed.mp4 \
              -pict_type_script ../bpm_iframes.js \
              -vcodec mpeg2video \
              -f rawvideo \
              -y p_tk_nopimb_forcemv_scale0_gmax_scthrshold_max.mpg

With the error being :
