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	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	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
