Hello! When using the mjpeg codec to convert an image from bmp to jpg format, a picture with one quantization table is created. I need two standard tables described in the jpeg iso / iec 10918-1 T.81 standard in Appendix K.1 and K.2 to be added to the output image file. I also found them in the ffmpeg source codes (jpegtables.c -> std_luminance_quant_tbl and jpegtables.c -> std_chrominance_quant_tbl [url: https://ffmpeg.org/doxygen/trunk/jpegtables_8c_source.html]. I looked through the mailing list archive and found old solutions ( https://ffmpeg.org/pipermail/libav-user/2015-July/008318.html), but now the av_codec_set_chroma_intra_matrix () function is declared depricated. How do I get what I want? How to set intra_matrix, chroma_intra_matrix and inter_matrix (in the description they are almost the same)? P.S .: Sorry, I don't speak English well. I use google translator.
