* udp: Only bind to the multicast address if in read-only modeMartin Storsjö2012-03-09
| | | | | | | | | | | | | | | This fixes sending back RTCP RR packets if receiving RTP over multicast. If the multicast stream is sent on demand (set up and signalled via RTSP), the sender might depend on getting RTCP RR packets knowing that there are listeners, otherwise the stream can be closed after a certain timeout. This fixes receiving RTSP streams over multicast on unix, from certain Axis cameras. Signed-off-by: Martin Storsjö <martin@martin.st>

* udp: Reorder commentsMartin Storsjö2012-03-09
| | | | | | | | | When this code was added in 36b532815cb83, the new code was added between the existing comment and the existing line of code, making the old comment seem to refer to the new code. This makes it read correctly. Signed-off-by: Martin Storsjö <martin@martin.st>
* ttadec: unbreak playback of matroska filesPaul B Mahol2012-03-08
| | | | | | | | Matroska demuxer needs to recreate tta header, so just display crc error without aborting. Signed-off-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* vorbisdec: avoid invalid memory accessAaron Colwell2012-03-08
| | | | | | | | | This fixes some invalid memory access caused later in the function by res_chan[] not being set for all channels. This happens when a channel doesn't appear a submap. This change simply returns a decoder error when this situation is detected. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* Fix uninitialized reads on malformed ogg files.Dale Curtis2012-03-08
| | | | | | | | | | The ogg decoder wasn't padding the input buffer with the appropriate FF_INPUT_BUFFER_PADDING_SIZE bytes. Which led to uninitialized reads in various pieces of parsing code when they thought they had more data than they actually did.

* huffyuv: add padding to classic (v1) huffman tables.Ronald S. Bultje2012-03-08
| | | | | | | | | | We slightly overread the input buffer, so we require padding at the end of the buffer, as is documented in the get_bits API. Without padding, we'll read uninitialized data or beyond the end of the .rodata, which may crash. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org
* png: convert to bytestream2 API.Ronald S. Bultje2012-03-08

* avs: fix infinite loop on end-of-stream.Ronald S. Bultje2012-03-07
| | | | | | | | | The codec would keep returning the last decoded frame if the stream contains B-frames, since it wouldn't clear that frame from the list of frames to be returned to the user. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind CC: libav-stable@libav.org

* sbrdsp.asm: convert all instructions to float/SSE ones.Reimar Döffinger2012-03-07
| | | | | | | | | | | Since the values are floats, using the float operations makes sense, improves performance on some CPUs and makes the code SSE compatible instead of needing SSE2. Based on suggestion by Jason. Signed-off-by: Reimar Döffinger <Reimar.Doeffinger@gmx.de> Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>

* dsputil: remove shift parameter from scalarproduct_int16Christophe GISQUET2012-03-07
| | | | | | | | | There is only one caller, which does not need the shifting. Other use cases are situations where different roundings would be needed. The x86 and neon versions are modified accordingly. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
* SBR DSP: unroll sum_squareChristophe GISQUET2012-03-07
