* svq3: Avoid a division by zeroMartin Storsjö2013-09-19
| | | | | | | | | | If the height is zero, the decompression will probably end up failing due to not fitting into the allocated buffer later anyway, so this doesn't need any more elaborate check.

| | | | | | | | | This is required, since invalid parameters actually could pass the switch check below. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* dca_parser: Handle changes in DCA frame sizeJohn Stebbins2013-09-17
| | | | | | | | A change in framesize caused a perpetual loss of synchronization. So read (and use) the frame size from the frame header instead of setting it only once. Signed-off-by: Diego Biurrun <diego@biurrun.de>

* avpacket: Fix error checking in packet_allocMartin Storsjö2013-09-16
| | | | | | | | | | Previously the wrong buffer pointer was checked, when buf instead of *buf was checked. But checking the return value instead is even better. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* proresdec: Properly make sure an index doesn't run past the limitMartin Storsjö2013-09-16
| | | | | | | | | If idx equaled num_coeffs - 1 on entry to the loop, the previous check failed to break out of the loop. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* pcm-dvd: Minor leftoversChristian Schmidt2013-09-13
| | | | Drop a pointless branch in uninit and use the compact copyright.
* pcm-dvd: Support channel configuration changesChristian Schmidt2013-09-13
| | | | | | | | | | The sample buffering logic does not take into account that the blocksize could change. Reset the buffer if the channel configuration changes, since if there are leftover samples, it is most likely a broken or misconcatenated stream. This could lead to negative numbers for missing_samples during decoding. Thanks to Michael Niedermeyer for pointing these out.

* alac: Check that the channels fit at the given offsetMartin Storsjö2013-09-03
| | | | | | | | | | | | | 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.
