Anton Khirnov	f7d15d2f42	4xm: operate with pointers to AVFrames instead of whole structs. This is more correct and avoids breaking extended_data.	13 years ago

Paul B Mahol	44fe118e0a	lavc/4xm: use bytestream2_get_bytes_left Also replace relevant bytestream2 functions with unchecked variants due code that already checks for overreads. Signed-off-by: Paul B Mahol <onemda@gmail.com>	13 years ago

Anton Khirnov	df9b956751	lavc: fix decode_frame() third parameter semantics for video decoders It's got_frame, not data size	13 years ago
Anton Khirnov	594d4d5df3	lavc: add a wrapper for AVCodecContext.get_buffer(). It will be useful in the upcoming transition to refcounted AVFrames.	13 years ago

Aneesh Dogra	9b55b4bb3a	4xm: Prevent buffer overreads. 4xm decoder while decoding i2 frames can overread the buffer if proper checks are not made. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Ronald S. Bultje	3fa646e859	Revert "4xm: Prevent buffer overreads." This reverts commit `295a7c0238`. The patch breaks decoding of regular files (e.g. fate-4xm-2).	14 years ago

Aneesh Dogra	4b84f68223	4xm: pass the correct remaining buffer size to decode_i2_frame(). frame_size is the number of bytes left in the packet, so if we are passing buf-4 we can safely read frame_size+4 bytes. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago
Aneesh Dogra	893f137679	4xm: fix calculation of the next output line position in decode_i2_frame(). The current code doesn't work unless width is an exact multiple of 16. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>	14 years ago

Justin Ruggles	bc78ceec2b	4xm: remove unneeded check for remaining unused data. This is unnecessary complication that only prints a message and does not affect decoding.	14 years ago
Michael Niedermayer	e1ba29c764	4xm: check if there are bits left in decode_i_block() Fixed Ticket753 Bug Found by: Diana Elena Muscalu Signed-off-by: Michael Niedermayer <michaelni@gmx.at>	14 years ago
Reimar Döffinger	371e165443	Try to set AVFrame.reference to correct values. I am not sure these new values are correct, not am I sure the semantics are a good idea since we do not seem to make any use of them but they caused a lot of confusion, but this seems to make things closer to matching the documentation.
