Vittorio Giovara	910247f172	lavc: Deprecate avctx.{inter,intra}_quant_bias They are used by dnxhd and mpegvideo_enc exclusively, move them to codec private options instead. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Michael Niedermayer	0ea099ad3e	avcodec/mpegvideo_enc: fix undefined shifts in ff_dct_quantize_c() Fixes: signal_sigsegv_35eac16_2762_cov_2704249783_missing_frames.avi Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	f1fa1eed2a	mpegvideo: Expand macro Having this macro in an header only facilitates the use of such header. The code increase is minimal and files have one less dependency on mpegvideo.h.	10 years ago
Vittorio Giovara	e7af52a68d	mpegvideo: rv10: Move function declaration to a separate header	10 years ago
Vittorio Giovara	e3d0f49abb	mpegvideo: h263: Move all tables to a single file	10 years ago
Vittorio Giovara	d1dd0d404c	mpegvideo: Move block permutation function where is used Mark it as static.	10 years ago
Vittorio Giovara	9bb11be0e5	mpegvideo: Split picture allocation for encoding and decoding The main ff_alloc_picture() function is made more generic with all the parameters necessary as arguments. This will allows to move most of the related functions to a separate file later. Right now wrappers are provided to try and minimize the number of changes in the code.	10 years ago
Vittorio Giovara	da0c8664b4	mpegvideo: Move various temporary buffers to a separate context	10 years ago
Vittorio Giovara	378a00087f	mpegvideo: Move tables to a separate file	10 years ago
Vittorio Giovara	2f15846ad7	mpegvideo: wmv2: Move function declarations	10 years ago
Michael Niedermayer	00f3bb2ef2	avcodec/mpegvideo: Factor ff_mpv_reallocate_putbitbuffer() out Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	561d3a57aa	avcodec/mpegvideo_enc: Update the buffer size as more slices are merged Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	4e17946f10	mpegvideo: Rework various functions not to use MpegEncContext directly	10 years ago
Vittorio Giovara	a3f4c930ac	mpegvideo: Have ff_mpeg_ref_picture use AVCodecContext directly	10 years ago
Vittorio Giovara	d528045558	mpegvideo: Have ff_mpeg_unref_picture use AVCodecContext directly This skips setting the memory to 0 but allows for reuse on different contextes. Oracle did not report any unsual activity because of it.	10 years ago
Vittorio Giovara	848e86f74d	mpegvideo: Drop flags and flags2 They are just duplicates of AVCodecContext members so use those instead.	10 years ago
Vittorio Giovara	0c69164f45	h263: Convert function to macro	10 years ago
Vittorio Giovara	3d71b1f8f0	mpegvideo_enc: Simplify picture allocation	10 years ago

Andreas Cadhalpun	66624ed631	rv10: check size of s->mb_width * s->mb_height If it doesn't fit into 12 bits it triggers an assertion. Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	10 years ago

Michael Niedermayer	9843746570	avcodec/mpegvideo_enc: correctly initialize chroma_intra_matrix for MPEG1/2 Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	0bcb040a2e	avcodec/mpegvideo_enc: Consider chroma_intra_matrix in dct_quantize_trellis_c() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	7cac568b39	avcodec/mjpegenc: support trellis quantization Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	7366bb38f1	avcodec/mpegvideo_enc: Add intra_chroma_ac_vlc_length, it will be needed for mjpeg Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	4531e2c489	avcodec/mpegvideo_enc: Fix number suffixes in rc_buffer_size calculation Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Vittorio Giovara	302ca6b20e	mpegvideo_enc: initialize the encoding context This prevents several uninitialized variable uses that take place towards the end of encoding. CC: libav-stable@libav.org Bug-Id: CID 700760	10 years ago
Michael Niedermayer	2a06c2a03e	mpegvideo_enc: Draw edges on input for non-multiple of 16 resolutions This improves motion estimation and avoids using uninitialized data for resolutions that aren't a multiple of 16. Prior to `d2a25c40`, the edges used to be initialized so that encoding was deterministic, but after that commit it started using uninitialized data (for non multiple of 16 resolutions).

Michael Niedermayer	2df5b506ca	avcodec/mpegvideo_enc: remove rtp_mode=0 for H261 Suggested-by: Thomas Volkert <silvo@gmx.net> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Martin Storsjö	91bfac759d	h261enc: Disallow sliced encoding This avoids trying to do sliced encoding, even if a slice/packet size is requested (via the -ps option or the rtp_payload_size field), since the encoder currently doesn't support it (or at least our decoder can't decode it, even if the h261_encode_gob_header function is hooked up to be called from the slicing part in mpegvideo_enc.c).

Michael Niedermayer	1441641d78	avcodec/mpegvideo_enc: Allocate only a small buffer and reallocate as needed This should reduce the memory requirement Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
Michael Niedermayer	755f7929c6	avcodec/mpegvideo_enc: Only enforce rc_max_available_vbv_use on first encoding attempt This reduces repeatly re-encoding to achieve VBV compliance Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	10 years ago
