Clément Bœsch	160979f4b4	lavc/utils: make sure the iconv descriptor can be opened only once. This prevents trying to do some subtitles conversion for each event when the character encoding is not found. It now aborts early instead of flooding stderr.	12 years ago
Anton Khirnov	1afddbe59e	avpacket: use AVBuffer to allow refcounting the packets. This will allow us to avoid copying the packets in many cases. This breaks ABI.	12 years ago
Reimar Döffinger	efa7f42020	Use the avstring.h locale-independent character type functions Make sure the behavior does not change with the locale. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Stefano Sabatini	70762508ec	lavc: Prettify printing of codec tags containing non alphanumeric characters Make av_get_codec_tag_string() show codec tag string characters in a more intelligible ways. For example the ascii char "@" is used as a number, so should be displayed like "[64]" rather than as a printable character. Apart alphanumeric chars, only the characters ' ' and '.' are used literally in codec tags, all the other characters represent numbers. This also avoids relying on locale-dependent character class functions. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
Reimar Döffinger	88d55b827d	Remove incorrect use of ctype.h functions. As far as I can tell the code should not change behaviour depending on locale in any of these places. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de>	12 years ago

Clément Bœsch	8732271e40	lavc: mark bitmap based subtitles codecs as such.	12 years ago
Michael Niedermayer	a53b144ec0	avcodec: add avpriv_color_frame() Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Anton Khirnov	d2a25c4032	get_buffer(): do not initialize the data. There may be more decoders that rely on this. Those should be found and fixed.	12 years ago
Diego Biurrun	c6507946d4	dsputil: Move STRIDE_ALIGN macro to the only place it is used	12 years ago
Michael Niedermayer	b75ac7c71c	lavc: include timebase in avcodec string at debug level. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago

Michael Niedermayer	d270c32025	avcodec_decode_audio: do not trust the channel layout, use the channel count. Fixes memory corruption Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	12 years ago
Luca Barbato	bff3607547	lavc: set the default rc_initial_buffer_occupancy rc_buffer_size is not set before. Solve the initial the rate control underflow issue reported in bug 222. CC: libav-stable@libav.org Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	12 years ago
Clément Bœsch	72ff8ee158	lavc: correctly set AVSubtitle format for text based subtitles.	12 years ago
Clément Bœsch	e3c25860dc	lavc/utils: reindent in avcodec_decode_subtitle2().	12 years ago
Clément Bœsch	67286fa98b	10l: export ff_bprint_to_extradata between libs using avpriv_ prefix. Both libavformat and libavcodec requires this function.	12 years ago
Clément Bœsch	36e61e24e7	lavc: add ff_bprint_to_extradata() helper and use it. This commit also makes sure the extradata and subtitle_header are NUL terminated, without taking into account the trailing '\0' in account in the size. At the same time, it should fix 'warning: dereferencing type-punned pointer will break strict-aliasing rules' warning for compilers who don't consider uint8_t and char compatibles.	12 years ago
Diego Biurrun	015da965a6	libavcodec/utils: Add braces to shut up gcc warnings libavcodec/utils.c:1050:5: warning: missing braces around initializer [-Wmissing-braces] libavcodec/utils.c:1314:5: warning: missing braces around initializer [-Wmissing-braces]	12 years ago

Stefano Sabatini	96d815fc0c	lavc: add pkt_size field to AVFrame	12 years ago
Janne Grunau	bd255f9feb	lavc: set frame parameters after decoding only if necessary Direct rendering capable decoders call get_buffer() which will set the frame parameters. Prevents frames with wrong parameters when a decoder outputs delayed frames after a resolution or pixel format change.	12 years ago

Anton Khirnov	e57c4706e9	lavc: don't reuse audio buffers Any performance gain from this is negligible and not worth the extra code.	12 years ago
Anton Khirnov	ff953fecff	lavc: set frame properties in ff_get_buffer(). There is no point in duplicating this code in every get_buffer() implementation.	12 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	12 years ago

Paul B Mahol	da8242e2d6	8svx: move pcm_s8_planar decoder to pcm.c Removes limitation of max 2 channels for pcm_s8_planar decoder by moving it to more natural place. AV_CODEC_ID_8SVX_RAW is not used by anything anymore and is going to be removed. Signed-off-by: Paul B Mahol <onemda@gmail.com>	12 years ago
