* 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.

* mov: Make sure the read sample count is nonnegativeMartin Storsjö2013-09-29
| | | | | | | | | This avoids setting a negative number of frames, ending up with a negative average frame rate. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* bfi: Avoid divisions by zeroMartin Storsjö2013-09-29
| | | | | | | | | If a zero-length video packet is to be returned, just return AVERROR(EAGAIN) and switch back to the audio stream. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* riffdec: Add sanity checks for the sample rateMartin Storsjö2013-09-29
| | | | | | | | This avoids a division by zero for G726. Reported-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* mvi: Add sanity checking for the audio frame sizeMartin Storsjö2013-09-29

* 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>

* avidec: Make sure a packet is large enough before reading its dataMartin Storsjö2013-09-29

* vqf: Make sure the bitrate is in the valid rangeMartin Storsjö2013-09-29
| | | | | | | | Even if the sample rate is valid, an invalid bitrate could pass the mode combination test below. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>
* vqf: Make sure sample_rate is set to a valid valueMartin Storsjö2013-09-29
| | | | | | | | | | This avoids divisions by zero later (and possibly assertions in time base scaling), since an invalid rate_flag combined with an invalid bitrate below could pass the mode combination test.

* lavf: Reset the entry count and allocation size variables on av_reallocp ↵Martin Storsjö2013-09-26
| | | | | | | | | | | | | | failures When av_reallocp fails, the associated variables that keep track of the number of elements in the array (and in some cases, the separate number of allocated elements) need to be reset. Not all of these might technically be needed, but it's better to reset them if in doubt, to make sure variables don't end up conflicting. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Allocate arrays with av_realloc if they will be realloced laterMartin Storsjö2013-09-26
| | | | | | | Pointers returned from av_malloc can't in general be passed to av_realloc. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpdec_qt: Add an accidentally removed allocation return value checkMartin Storsjö2013-09-26
| | | | | | This check was mistakenly removed in 5626f994f. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Add support for listen modeMartin Storsjö2013-09-26
| | | | | | | | | Also add options for specifying a certificate and key, which can be used both when operating as client and as server. Partially based on a patch by Peter Ross. Signed-off-by: Martin Storsjö <martin@martin.st>
* http: Pass options through to the nested protocolMartin Storsjö2013-09-26
| | | | | | | | When passing a dict to the nested protocol, it will consume the used options from it, so a separate copy needs to be used when reopening the connection multiple times. Signed-off-by: Martin Storsjö <martin@martin.st>
* tls: Add options for verifying the peer certificateMartin Storsjö2013-09-26
| | | | | | | | | | | | | | | | | | | | A file containing the trusted CA certificates needs to be supplied via the ca_file AVOption, unless the TLS library has got a system default file/database set up. This doesn't check the hostname of the peer certificate with openssl, which requires a non-trivial piece of code for manually matching the desired hostname to the string provided by the certificate, not provided as a library function. That is, with openssl, this only validates that the received certificate is signed with the right CA, but not that it is the actual server we think we're talking to. Verification is still disabled by default since we can't count on a proper CA database existing at all times. Signed-off-by: Martin Storsjö <martin@martin.st>

* 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>
* configure: Enable -Qansi-alias for icl 14+Alex Smith2013-09-24

* h263dec: Remove a hack that can cause infinite loopsMartin Storsjö2013-09-23
