Hello, Here a little modif for better H264 decoding quality with libavcodec in Opal : in file opal-3.6.6/plugins/video/H.264/h264-x264.cxx, in the method H264DecoderContext::H264DecoderContext(), after creating the context I inserted before line 204 the lines :
_context->workaround_bugs = FF_BUG_AUTODETECT; _context->error_recognition = FF_ER_AGGRESSIVE; _context->idct_algo = FF_IDCT_H264; _context->error_concealment = FF_EC_GUESS_MVS | FF_EC_DEBLOCK; _context->flags = CODEC_FLAG_INPUT_PRESERVED | CODEC_FLAG_EMU_EDGE; _context->flags2 = CODEC_FLAG2_BRDO | CODEC_FLAG2_MEMC_ONLY | CODEC_FLAG2_DROP_FRAME_TIMECODE | CODEC_FLAG2_SKIP_RD | CODEC_FLAG2_CHUNKS; and the image is much better, at least when called by a Grandstream GXV3000. I think that the most important one is the flag CODEC_FLAG2_CHUNKS in _context->flags2.
