optimized the normal bitstream writer, its faster than the alternative one on p3 now ... lets hope its at least not slower on p4 & k7

Originally committed as revision 299 to svn://svn.ffmpeg.org/ffmpeg/trunk

f004ca1c 02/13/2002 03:26 PM Michael Niedermayer

optimized encode_dc() (+2% speed on P3 for mpeg1 intra only encodings)

Originally committed as revision 298 to svn://svn.ffmpeg.org/ffmpeg/trunk

80feb2a2 02/13/2002 04:19 AM Michael Niedermayer

optimize mpeg1_encode_block()
(makeing some constant arrays global, merging put_bits(), ...)

Originally committed as revision 297 to svn://svn.ffmpeg.org/ffmpeg/trunk

4f0f8bfc 02/12/2002 10:43 PM Michael Niedermayer

aligned bitstream writer (1% slower on p3 but perhaps its faster on p4?)

Originally committed as revision 296 to svn://svn.ffmpeg.org/ffmpeg/trunk

17592475 02/12/2002 03:43 PM Michael Niedermayer

alternative bitstream writer (disabled by default, uncomment #define ALT_BISTREAM_WRITER in common.h if u want to try it)

- More work on preliminary bit rate control, just to be able to get an
average variance for picture's MBs so we can adjust qscale on the MB layer.

37fbfd0a 02/10/2002 01:56 AM Juanjo

- Now the ME is done for the entire picture when enconding, the
DCT/Quantization is done after we have calculated all the MV of the picture.
- This is the preamble for a better bit rate control.

81401c1f 02/09/2002 04:59 PM Juanjo

- Fixes on RTP and GOB headers for H.263.
- RTP callback system implemented for H.263/H.263+.
- Bug fix on DC coefficients of H.263.
- H.263 decoder now returns PTS on picture number.

PATCH by Rik Snel <>
this includes the range for quantized dct coefficients in dct_quantize() (-1023...1023)

Originally committed as revision 291 to svn://svn.ffmpeg.org/ffmpeg/trunk

PATCH by Rik Snel <>

this patch enhances the jpeg header writer. It can be asked to omit
quantisation and huffman tables and it can write different horizontal and
vertical sampling factors. (the last thing is useless for libavcodec
itself (because libavcodec only handles YUV420P at ecoder level), but the...
