| | | | fdct is only initialized if encoders are enabled.

* pcx: Return an error on broken palette if err_detect is set to 'explode'Martin Storsjö2013-09-29
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* pcx: Check the packet size before assuming it fits a paletteMartin Storsjö2013-09-29
| | | | | | | | This fixes reads out of bounds. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* rpza: Fix a buffer size checkMartin Storsjö2013-09-29
| | | | | | | | | We read 2 bytes for 15 out of 16 pixels, therefore we need to have at least 30 bytes, not 16. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* xxan: Disallow odd widthMartin Storsjö2013-09-29
| | | | | | | | | Decoded data is always written in pairs within this decoder. This fixes writes out of bounds. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* xan: Only read within the data that actually was initializedMartin Storsjö2013-09-29
| | | | | | Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* xan: Use bytestream2 to limit reading to within the bufferMartin Storsjö2013-09-29
| | | | | | Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* pcx: Consume the whole packet if giving up due to missing paletteMartin Storsjö2013-09-29
| | | | | | | | | Previously, we returned 0, meaning successful decoding but 0 bytes consumed, leading to an infinite loop. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* pngdec: Stop trying to decode once inflate returns Z_STREAM_ENDMartin Storsjö2013-09-29
| | | | | | | | | | If the input buffer contains more data after the deflate stream, the loop previously left running infinitely, with inflate returning Z_STREAM_END. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* alac: Do bounds checking of lpc_order read from the bitstreamMartin Storsjö2013-09-29
| | | | | | | | | 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>

* lavc: add support for interleaved chroma formats to libx264.Kieran Kunhya2013-09-24
| | | | | | Interleaved chroma is x264's native format Signed-off-by: Anton Khirnov <anton@khirnov.net>
* h264_sei: check SEI sizeMichael Niedermayer2013-09-24
| | | | Signed-off-by: Anton Khirnov <anton@khirnov.net>
* h264: do not discard NAL_SEI when skipping framesRainer Hochecker2013-09-24
| | | | | | Setting AVDISCARD_NONREF (e.g. after flushing) resulted in 100% dropped frames. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* h264: log extradata skip only for non-ignored NALsVittorio Giovara2013-09-24

* mpegvideo: Initialize chroma_*_shift and codec_tag even if the size is 0Martin Storsjö2013-09-24
| | | | | | | | | | | | This fixes breakage in a few fate tests on certain setups (that for some reason didn't break on OS X) after the previous commit (8812a8057). Currently, some video streams are initialized in ff_MPV_common_init with width/height set at 0 and only changed to a proper video size with ff_MPV_common_frame_size_change later. The breakage was diagnosed by Anton Khirnov. Signed-off-by: Martin Storsjö <martin@martin.st>
* h263dec: Remove a hack that can cause infinite loopsMartin Storsjö2013-09-23
| | | | | | | | The actual usefulness of the hack is not known, and it does cause infinite loops with some broken input files. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* vc1dec: Undo mpegvideo initialization if unable to allocate tablesMartin Storsjö2013-09-22
| | | | | | | | | | Previously, s->context_initialized was left set to 1 if ff_vc1_decode_init_alloc_tables failed, skipping the initialization completely on the next decode call. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* vc1dec: Fix leaks in ff_vc1_decode_init_alloc_tables on errorsMartin Storsjö2013-09-22

* 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. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
