Michael Niedermayer	72743aef03	imgconvert: Implement avcodec_find_best_pix_fmt_of_list() The old avcodec_find_best_pix_fmt() was insufficient due to 64 pix_fmt limit. In ffmpeg this problem has been solved long ago through avcodec_find_best_pix_fmt2() Today libav has added a incompatible modified version of avcodec_find_best_pix_fmt2() under the same name, thus again breaking ABI/API ... The avcodec_find_best_pix_fmt_of_list() added in this commit here makes the libav API available to ffmpeg users too. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	13 years ago

Janne Grunau	ac29054fda	imgconvert: add avcodec_find_best_pix_fmt2() The number of pixel formats outgrew the number of available bits in the bitmask used in avcodec_find_best_pix_fmt(). avcodec_find_best_pix_fmt2() uses a PIX_FMT_NONE terminated list of pixel formats instead.	13 years ago

Stefano Sabatini	e6674e46ec	lavu/imgutils: create misc functions for dealing with buffers Move the lavc/imgconvert functions and rename them as follows: avpicture_get_size -> av_image_get_buffer_size() avpicture_fill -> av_image_fill_arrays() avpicture_layout -> av_image_copy_to_buffer() The new functions have an align parameter, which allows to define the linesize alignment assumed in the buffer (which is set or read). The names of the functions are consistent with the lavu/samples API (av_samples_get_buffer_size(), av_samples_fill_arrays()).	13 years ago
Stefano Sabatini	18b4404dc3	lavc/imgconvert: fix check on av_image_check_size() return code in avpicture_get_size() The documentation states that av_image_check_size() will return a negative value in case of error, while the check is done on ret != 0. Also return a proper error code rather than -1 in case the check fails.	13 years ago

Diego Biurrun	44b0edda3f	Drop some pointless void* return value casts from av_malloc() invocations.	13 years ago
Anton Khirnov	586657c20a	lavc: deprecate img_get_alpha_info(). It's never been touched or used in any way since it was added in 2003 and only works for PIX_FMT_PAL8, which makes me conclude that nobody's ever used it.	13 years ago
Matthew Einhorn	e662b263d9	Fixes avpicture_layout to not write past buffer end. avpicture_get_size() returns the size of buffer required for avpicture_layout. For pseudo-paletted formats (gray8...) this size does not include the palette. However, avpicture_layout doesn't know this and still writes the palette. Consequently, avpicture_layout writes passed the length of the buffer. This fixes it by fixing avpicture_layout so that it doesn't write the palette for these formats.

Michael Niedermayer	1287c81d65	imgconvert: make avcodec_find_best_pix_fmt2() more bug robust against future changes Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Matthew Einhorn	adfe59407e	Adds a new pix fmt function that selects the best dest fmt from among 2 formats to convert to, given a certain src format. Similar to avcodec_find_best_pix_fmt(), but instead only compares two destination pix fmts and selects one of these fmts as the best dest format when converting from a given source format. Also, as opposed to avcodec_find_best_pix_fmt() which supports only the first 64 defined pixel formats, this supports as input any of the defined pixel formats. Also replaces the old function to rely on the new function. Signed-off-by: Matthew Einhorn <moiein2000@gmail.com> Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
