* configure: Force mingw's ld to keep the reloc sectionAlex Smith2015-09-23
| | | | | | | | | | Binutils will always strip the relocation information from executable files even if it needs it (dynamicbase/ASLR). We can work around this by using the pic-executable flag combined with setting the correct entry point since apparently ld forgets what that should be. This problem affects both 32 and 64-bit mingw-w64. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* hls: only seek if there is an offsetAndreas Cadhalpun2015-09-22
| | | | | | | | | | | If there is no #EXT-X-BYTERANGE specified, there is no need to seek. Seeking fails anyway for rtmp, because this protocol does not support url_seek. This fixes CNN.m3u from trac ticket 4797 (i.e. Debian bug #798189). Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: Andreas Cadhalpun <Andreas.Cadhalpun@googlemail.com>

* avcodec/dvdsubdec: reject some broken packetswm42015-09-22
| | | | | | | | | | | | | If cmd_pos is broken, this would just keep accumulating packets in the reassembly buffer, until it fails and flushes the buffer on overflow. Since packets are usually rather small, this will take a lot of subtitle packets. The perceived effect is that subtitles are not displayed anymore after the faulty packet was passed to the decoder. I'm not terribly sure about this, but on the other hand this code is active only when fragmented packets need to be reassembled. Fixes sample file in trac issue #4872.
* avcodec/dvdsub: fix partial packet assemblywm42015-09-22
| | | | | | | | | | Assuming the first and second packets are partial, this would append the reassembly buffer (ctx->buf) to itself with the second append_to_cached_buf() call, because buf is set to ctx->buf. I do not know a valid sample file which triggers this, and do not know if packets can be split into more than 2 sub-packets, but it triggered with a (differently) broken sample file in trac issue #4872.
* avformat/hls: fix some cases of HLS streams which require cookieswm42015-09-22
| | | | | | | | Broken by commit ba12ba859aabfa7153ba397d869db13acdaba340. This only happens with HLS streams which use encryption and require preserving cookies sent by the server. Fixes trac issue #4846.

* avformat/assdec: do not drop duplicate subtitleswm42015-09-21
| | | | | Duplicates are perfectly legitimate with this format. A correct renderer will typically show them stacked.
* avformat/vobsub: do not attempt to check duplicate subtitleswm42015-09-21
| | | | | | | | | | | | | | | | Some .idx files actually contain duplicate subtitle events: timestamp: 00:07:52:600, filepos: 00004e800 timestamp: 00:07:52:600, filepos: 00004f800 The second will be dropped, because it has same pts, duration, and text (the text is just a dummy empty string; the real data is retrieved when actually reading vobsub subtitle packets). Dropping this is probably not intended/safe, so avoid it. See trac issue #4872 for a sample. This patch doesn't fix decoding of the sample, though.
* avformat/subtitles: make dropping duplicate events optionalwm42015-09-21

* avformat/vobsub: compare correct packet stream IDswm42015-09-21
| | | | | | | | | | | | The stream ID is essentially an arbitrary number defined by the .idx file headers. They have to match the IDs in the .sub stream. The vobsub demuxer assumed the IDs would just start from 0, increassing by 1 for each stream. This is not correct. In the sample I had, the IDs were starting from 1, leading to no subtitles being displayed at all. Fix this by using the correct stream ID. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>

* lavfi: drop the requirement that request_frame returns a frame.Nicolas George2015-09-20
