Vittorio Giovara	2268db2cd0	lavu: Drop the {minus,plus}1 suffix from AVComponentDescriptor fields The new fields can be accessed directly and are more intelligible. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	9 years ago
Michael Niedermayer	e36db49b7b	avcodec: Add a min size parameter to ff_alloc_packet2() This parameter can be used to inform the allocation code about how much downsizing might occur, and can be used to optimize how to allocate the packet Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>	10 years ago
Vittorio Giovara	d6604b29ef	Gather all coded_frame allocations and free functions to a single place Allocating coded_frame is what most encoders do anyway, so it makes sense to always allocate and free it in a single place. Moreover a lot of encoders freed the frame with av_freep() instead of the correct API av_frame_free(). This bring uniformity to encoder behaviour and prevents applications from erroneusly accessing this field when not allocated. Additionally this helps isolating encoders that export information with coded_frame, and heavily simplifies its deprecation. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>	10 years ago
Andreas Cadhalpun	cb658d17b6	libopenjpegenc: use variable instead of type for sizeof Reviewed-by: Michael Niedermayer <michaelni@gmx.at> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>	10 years ago
Andreas Cadhalpun	1577526b47	libopenjpegenc: add NULL check for img before accessing it If opj_image_create fails to allocate an image it returns NULL, which causes a segmentation fault at 'img->x0 = 0'.

Jean First	1f13348f7d	lavc/libopenjpegenc: move opj_setup_encoder to libopenjpeg_encode_frame if the openjpeg parameter tcp_rates is not 0 ( using the ffmpeg compression_level option ) every 2nd image per thread is badly encoded. By moving the opj_setup_encoder function from libopenjpeg_encode_init to libopenjpeg_encode_frame this can be prevented. This fixes ticket #3754.

Vittorio Giovara	e96c3b81ca	avutil: rename AV_PIX_FMT_Y400A to AV_PIX_FMT_YA8 The rationale is that you have a packed format in form <greyscale sample> <alpha sample> <greyscale sample> <alpha sample> and shortening greyscale to 'G' might make one thing about Greenscale instead. An alias pixel format and color space name are provided for compatibility.	11 years ago
