Luca Barbato	b25e49b187	mjpegdec: properly report unsupported disabled features When JPEG-LS support is disabled the decoder would feed the data to the JPEG Lossless decode_*_scan function resulting in faulty decoding. CC: libav-stable@libav.org	12 years ago
Ronald S. Bultje	28bc406c84	mjpeg: Use hpeldsp instead of dsputil for half-pel functions Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago

Diego Biurrun	88bd7fdc82	Drop DCTELEM typedef It does not help as an abstraction and adds dsputil dependencies. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	12 years ago
Janne Grunau	6a1aa5cb26	mjpeg: initialize input padding after unescaped buffer to zero Fixes valgrind --undef-value-errors=yes warnings caused by valid overreads in the fate vsynth jpegls, cover-art-ape and cover-art-wv tests.	12 years ago
Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	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
Diego Biurrun	f75f4194d1	Restructure av_log_missing_feature message Some invocations include a verb in the log message, others do not. Yet av_log_missing_feature expects callers to provide a verb. Change the function to include a verb instead and update the callers accordingly. The result is a more natural function API and correct English in the function invocations.	12 years ago

Ronald S. Bultje	5eec5a79da	jpeg: handle progressive in second field of interlaced. Progressive data is allocated later in decode_sof(), not allocating that data leads to NULL dereferences. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org	13 years ago

Diego Biurrun	1c4717be4f	mjpegdec: use correct variable in av_log invocation libavcodec/mjpegdec.c:1463: warning: format ‘%x’ expects type ‘unsigned int’, but argument 5 has type ‘const uint8_t *’	13 years ago

Janne Grunau	e268a352af	mjpegdec: parse RSTn to prevent skipping other data in mjpeg_decode_scan Check explicitly if enough bits are left to prevent an infinite loop when the bitstream buffer is not followed by zero-padding. Based on patches by Michael Niedermayer <michaelni@gmx.at>.	13 years ago
