* rtpproto: Support more than one SSM include address, support excludesEd Torbett2013-07-29
| | | | Signed-off-by: Martin Storsjö <martin@martin.st>
* udp: Keep track of include and exclude sources separatelyEd Torbett2013-07-29
| | | | | | | This allows us to explicitly fail if the caller tried to set both inclusions and exclusions at the same time. Signed-off-by: Martin Storsjö <martin@martin.st>
* udp: Allow specifying multicast include/blocks as host names as wellEd Torbett2013-07-29
| | | | | | | | Previously this only allowed literal IP addresses. When these are conveyed in a SDP file as in RFC4570, host names are allowed as well. Signed-off-by: Martin Storsjö <martin@martin.st>
* avisynth: Fix a "AVISynth" vs. "AviSynth" struct name typoDiego Biurrun2013-07-29
| | | | Also fix some similar typos in comments and documentation.
* hls: Free packets when skipping packets when seekingMartin Storsjö2013-07-29

* hlsproto: Store all durations in AV_TIME_BASEMartin Storsjö2013-07-29
| | | | | | | Also parse segment durations as floating point, which is allowed since HLS version 3. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Store all durations in AV_TIME_BASEMartin Storsjö2013-07-29
| | | | | | | | | Also parse segment durations as floating point, which is allowed since HLS version 3. This is based on a patch by Zhang Rui. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Store first_timestamp in units of AV_TIME_BASEMartin Storsjö2013-07-29
| | | | | | | | | | | | | | | | | | | | | When first_timestamp was stored as-is, its actual time base wasn't known later in the seek function. Additionally, the logic (from 795d9594cfa) for scaling it based on stream_index is flawed - stream_index in the seek function only specifies which stream the seek timestamp refers to, but obviously doesn't say anything about which stream first_timestamp belongs to. In the cases where stream_index was >= 0 and all streams had the same time base, this didn't matter in practice. Seeking taking first_timestamp into account is problematic when one variant is mpegts (with real timestamps) and one variant is raw ADTS (with timestamps only being accumulated packet duration), where the variants start at totally different timestamps. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Create an AVProgram for each variantLYF2013-07-29
| | | | | | | | | Without the information, an application may choose audio from one variant and video from another variant, which leads to fetching two variants from the network. This enables av_find_best_stream() to find matching audio and video streams, so that only one variant is fetched. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Respect the different stream time bases when comparing dtsMichael Niedermayer2013-07-29
| | | | | | | | | | | | | | | | | | Also adjust the streams timestamps according to their start timestamp when comparing. This helps getting correctly interleaved packets if one stream lacks timestamps (such as a plain ADTS stream when the other variants are full mpegts) when the others have timestamps that don't start from zero. This probably doesn't work properly if such a stream is temporarily disabled (via the discard flags) and then reenabled, and such streams are hard to correctly sync against the other streams as well - but this works better than before at least. The segment number restriction makes sure all variants advance roughly at the same pace as well. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Set stream offset before opening a chained demuxerMartin Storsjö2013-07-29
| | | | | | | This makes sure we don't accidentally check discard flags for the wrong stream. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Don't check discard flags until the parent demuxer's streams actually existMichael Niedermayer2013-07-29
| | | | | | | | If passing the end of one segment while initializing the chained demuxer, the parent demuxer's streams aren't set up yet, so we can't recheck the discard flags. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Copy the time base from the chained demuxerMichael Niedermayer2013-07-29
| | | | | | | When a variant stream isn't mpegts but e.g. raw adts, the default time base (90k) isn't correct. Signed-off-by: Martin Storsjö <martin@martin.st>
* hls: Return all packets from a previous variant before moving on to the next oneMartin Storsjö2013-07-29
| | | | | | | | | | This serves as a safeguard; normally we want to use the dts comparison to interleave packets from all active variants. If that dts comparison for some reason doesn't work as intended, make sure that all packets in all variants for a certain sequence number have been returned before moving on to the next one. Signed-off-by: Martin Storsjö <martin@martin.st>
* lavf: Don't interpret just slightly broken timestamps as wraparoundMichael Niedermayer2013-07-29
| | | | | | | This avoids breaking some slightly incorrect (dts > pts) timestamps in sample HLS streams from Apple. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtsp: Support multicast source filters (RFC 4570)Ed Torbett2013-07-19
| | | | | | | | | | This supports inclusion of one single IP address for now, at the media level. Specifying the filter at the session level (instead of at the media level), multiple source addresses, exclusion, or using FQDNs instead of plain IP addresses is not supported (yet at least). Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Check the source IP if one single source has been specifiedMartin Storsjö2013-07-19
| | | | | | | | | | | | | | If another peer is sending unicast packets to the same port that we are listening on, those packets can end up being received despite using source specific multicast. For those cases, manually check the source address of received packets against the intended source address. This only handles the case when the source list is one single IP address for now, which probably is the most common case. Based on a patch by Ed Torbett. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpproto: Support IGMPv3 source specific multicast inclusionEd Torbett2013-07-19
| | | | | | | | | Blocking/exclusion is not supported yet. The rtp protocol parameter takes the same form as the existing sources parameter for the udp protocol. Signed-off-by: Martin Storsjö <martin@martin.st>

* mov: Do not allow updating the time scale after it has been setMartin Storsjö2013-07-15
| | | | | | | | | | | | The time scale is set in mdhd, and later validated in the enclosing trak atom once all of its children have been parsed. A loose mdhd atom outside of a trak atom could update the time scale of the last stream without any validation.

| | | | | | | | | The RTP timestamps can be decreasing for codecs with B-frames. For these cases, make sure the timestamps in the MP4 file track itself are nondecreasing, and add an offset to the RTP packet hint instead to produce the intended RTP timestamp.

* rmdec: Use the AVIOContext given as parameter in rm_read_metadata()Michael Niedermayer2013-07-07
| | | | | | | | | | | | | | | This fixes crashes when playing back certain RealRTSP streams. When invoked from the RTP depacketizer, the full realmedia demuxer isn't invoked, but only certain functions from it, where a separate AVIOContext is passed in as parameter (for the buffer containing the data to parse). The functions called from within those entry points should only be using that parameter, not s->pb. In the depacketizer case, s is the RTSP context, where ->pb is null.
