* | alac: Reject rice_limit 0 if compression is used | Andreas Cadhalpun | 2015-05-08 |
| | | | | | | | | | | | If in compression mode rice_limit = 0 leads to call `show_bits(gb, k)` in `decode_scalar` with k = 0. Request a sample in case it is valid and it should be accepted. Signed-off-by: Luca Barbato <lu_zero@gentoo.org> CC: libav-stable@libav.org | ||

* | alac: Do bounds checking of lpc_order read from the bitstream | Martin Storsjö | 2013-09-29 |
| | | | | | | | | | In lpc_prediction(), we write up to array element 'lpc_order' in an array allocated to hold 'max_samples_per_frame' elements. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st> | ||
* | alac: Check that the channels fit at the given offset | Martin Storsjö | 2013-09-03 |
| | | | | | | | | | | | | | The code tries to decode a number of channels at the offset given by the ff_alac_channel_layout_offsets table. Even if the number of channels decoded so far doesn't exceed the total number of channels, we need to check that we actually can decode that number of channels at this offset as well.

* | alac: Limit max_samples_per_frame | Martin Storsjö | 2013-09-03 |
| | | | | | | | | | | Otherwise buffer size calculations in allocate_buffers could overflow later, making the code think a large enough buffer actually was allocated.

* | alac: decode directly to the user-provided AVFrame | Justin Ruggles | 2013-02-12 |
| | |||
* | alacdec: do not be too strict about the extradata size | Justin Ruggles | 2012-12-22 |
| | | | | | | | Sometimes the extradata has duplicate atoms, but that shouldn't prevent decoding. Just ensure that it is at least 36 bytes as a sanity check. CC: libav-stable@libav.org | ||
* | alacenc: add support for multi-channel encoding | Justin Ruggles | 2012-12-05 |
| | |||

| | | | | It will be useful in the upcoming transition to refcounted AVFrames. | ||

* | alac: check for truncated packets | Justin Ruggles | 2012-07-27 |
| | | | | | This will give a clearer error message when the error is caused by a truncated packet. | ||

| | | | | Reversing the lpc coefficient order simplifies indexing in the filter. | ||

* | alac: split element parsing into a separate function | Justin Ruggles | 2012-07-19 |
| | | | | | This will make multi-channel implementation simpler. Based partially on a patch by Andrew D'Addesio <modchipv12@gmail.com>. | ||
* | alac: support a read sample size of up to 32 | Justin Ruggles | 2012-07-19 |
| | | | | | Use get_bits_long() in decode_scalar(). Use unsigned int for decoded value. | ||
* | alac: output in planar sample format | Justin Ruggles | 2012-07-19 |
| | | | | | Avoids unneeded interleaving and allows for reusing the AVFrame output buffer as the internal buffer for 24-bit and 32-bit sample size. | ||

* | alac: conditionally set sign_modifier to 1 | Justin Ruggles | 2012-07-19 |
| | | | | | It is already unconditionally set to 0 prior to this, so we can modify it only when needed. | ||
* | alac: eliminate 2 unneeded local variables in bastardized_rice_decompress() | Justin Ruggles | 2012-07-19 |
| | | | | | x_modified is just unnecessary, and final_val can be removed by simplifying the unsigned-to-signed conversion. | ||
