x262, Mpeg-2 видео кодировщик, работающий на базе видео энкодера x264.
x262, an mpeg-2 encoder building on the best-in-class features of x264.
Изменения / Changes:
-
-
MPEG-2: Restrict colorspace to 4:2:0 or 4:2:2.
-
MPEG-2: Support Matroska output.
-
MPEG-2: Allow forcing a higher profile than strictly necessary.
-
MPEG-2: Change default logging. Print "x262" instead of "x264" so that MPEG-2/H.264 is more obvious.
-
MPEG-2: API improvements. Library users can simply call x264_param_default_preset_mpeg2() to setup MPEG-2 encoding. Other API functions will not overwrite any mandatory settings. Also modify the CLI so that the --mpeg2 and --no-mpeg2 options work however the binary is called
-
MPEG-2: Prefix level names.
-
MPEG-2: Change lookahead QP. 1 was chosen because its qscale is comparable to QP 12 for H.264. Improves PSNR/SSIM a tiny bit.
-
Merge remote-tracking branch 'x264/master';
-
Fix reading of uninitialised parameter when encoding from the CLI.;
-
MPEG-2: Update copyright;
-
MPEG-2: Initial interlaced encoding support. Uses VSAD to detect interlaced macroblocks. Currently limited to 4:2:0 only..
Caution, this experimental version!
