* Supply a User-Agent header when opening rtsp streams.Carl Eugen Hoyos2013-07-11
| | | | | | Some rtsp servers like the IP Cam IcyBox IB-CAM2002 need it. Fixes ticket #2761. Reported, analyzed and tested by trac user imavra.
* lavf/segment: add initial_offset optionStefano Sabatini2013-07-11
| | | | Should address trac ticket #2224.
* avformat/AVFormatContext: Move fields down to match the forkMichael Niedermayer2013-07-09
| | | | | | | | | | | | | | | | | | | | avconv uses private and internal fields from libavformat, we thus must match the layout even of the fields marked non public. Otherwise ffmpegs libavformat could not be used as a dropin replacement on debian/ubuntu The current soname of libavformat was not part of any release nor are any fields marked public moved thus in theory no installed shared lib ABI breakage should occur. Still the need for this change is unfortunate and chilling. If you installed shared libs from a recent development version of libavformat that is more recent than the last release. You probably want to check or rebuild applications that linked to it. minor versions of avformat & avdevice are bumped to allow detecting this as both use the updated struct Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

* lavf/http: add support for reading streamcast metadatawm42013-07-02
| | | | | | | | | | | | | | | | | | | Allow applications to request reading streamcast metadata. This uses AVOptions as API, and requires the application to explicitly request and read metadata. Metadata can be updated mid-stream; if an application is interested in that, it has to poll for the data by reading the "icy_metadata_packet" option in regular intervals. There doesn't seem to be a nice way to transfer the metadata in a nicer way. Converting the metadata to ID3v2 tags might be a nice idea, but the libavformat mp3 demuxer doesn't seem to read these tags mid-stream, and even then we couldn't guarantee that tags are not inserted in the middle of mp3 packet data. This commit provides the minimum to enable applications to retrieve this information at all. Signed-off-by: Stefano Sabatini <stefasab@gmail.com>
* lavf: add AV_DISPOSITION flags for WebVTT text track kindsMatthew Heaney2013-06-25
| | | | | | | | | | | There are 4 separate WebVTT text track kinds: subtitles (the default if not otherwise specified), captions, descriptions, and metadata. The WebM muxer needs to know which WebVTT text track kind this is, in order to synthesize the correct track type and codec id. To allow a demuxer to indicate the text track kind of the input, a new set of AV_DISPOSITION flag values has been added, corresponding to each of the non-default text track kind values.

* lavf/id3v2enc: fix cover art display on some softwareMatthieu Bouron2013-05-30
| | | | | | | | | | | | | | Adding an arbitrary amount of padding bytes at the end of the ID3 metadata fixes cover art display for some software (iTunes, Traktor, Serato, Torq). For reference (ID3 metadata): [ Apic frames ] -> cover doesn't show up [ Apic frames, Padding ] -> ok [ Apic frames, ID3 frames ] -> ok [ ID3 frames, Apic frames ] -> cover doesn't show up [ ID3 frames, Apic frames, Padding ] -> ok
* tta: remove pointless codePaul B Mahol2013-05-30
| | | | | Checking seek table crc in decoder is pointless, as seek table is not used in decoder anyway, so also stop storing seek table into extradata.

* | subtitles: introduce ASS codec id and use it.Clément Bœsch2013-04-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, we have a AV_CODEC_ID_SSA, which matches the way the ASS/SSA markup is muxed in a standalone .ass/.ssa file. This means the AVPacket data starts with a "Dialogue:" string, followed by a timing information (start and end of the event as string) and a trailing CRLF after each line. One packet can contain several lines. We'll refer to this layout as "SSA" or "SSA lines". In matroska, this markup is not stored as such: it has no "Dialogue:" prefix, it contains a ReadOrder field, the timing information is not in the payload, and it doesn't contain the trailing CRLF. See [1] for more info. We'll refer to this layout as "ASS". Since we have only one common codec for both formats, the matroska demuxer is constructing an AVPacket following the "SSA lines" format. This causes several problems, so it was decided to change this into clean ASS packets. Some insight about what is changed or unchanged in this commit: CODECS ------ - the decoding process still writes "SSA lines" markup inside the ass fields of the subtitles rectangles (sub->rects[n]->ass), which is still the current common way of representing decoded subtitles markup. It is meant to change later. - new ASS codec id: AV_CODEC_ID_ASS (which is different from the legacy AV_CODEC_ID_SSA) - lavc/assdec: the "ass" decoder is renamed into "ssa" (instead of "ass") for consistency with the codec id and allows to add a real ass decoder. This ass decoder receives clean ASS lines (so it starts with a ReadOrder, is followed by the Layer, etc). We make sure this is decoded properly in a new ass-line rectangle of the decoded subtitles (the ssa decoder OTOH is doing a simple straightforward copy). Using the packet timing instead of data string makes sure the ass-line now contains the appropriate timing. - lavc/assenc: just like the ass decoder, the "ssa" encoder is renamed into "ssa" (instead of "ass") for consistency with the codec id, and allows to add a real "ass" encoder. One important thing about this encoder is that it only supports one ass rectangle: we could have put several dialogue events in the AVPacket (separated by a \0 for instance) but this would have cause trouble for the muxer which needs not only the start time, but also the duration: typically, you have merged events with the same start time (stored in the AVPacket->pts) but a different duration. At the moment, only the matroska do the merge with the SSA-line codec. We will need to make sure all the decoders in the future can't add more than one rectangle (and only one Dialogue line in it obviously). FORMATS ------- - lavf/assenc: the .ass/.ssa muxer can take both SSA and ASS packets. In the case of ASS packets as input, it adds the timing based on the AVPacket pts and duration, and mux it with "Dialogue:", trailing CRLF, etc. - lavf/assdec: unchanged; it currently still only outputs SSA-lines packets. - lavf/mkv: the demuxer can now output ASS packets without the need of any "SSA-lines" reconstruction hack. It will become the default at next libavformat bump, and the SSA support will be dropped from the demuxer. The muxer can take ASS packets since it's muxed normally, and still supports the old SSA packets. All the SSA support and hacks in Matroska code will be dropped at next lavf bump.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The handling of the environment variable no_proxy, present since one of the initial commits (de6d9b6404), is inconsistent with how many other applications and libraries interpret this variable. Its bare presence does not indicate that the use of proxies should be skipped, but it is some sort of pattern for hosts that does not need using a proxy (e.g. for a local network). As investigated by Rudolf Polzer, different libraries handle this in different ways, some supporting IP address masks, some supporting arbitrary globbing using *, some just checking that the pattern matches the end of the hostname without regard for whether it actually is the right domain or a domain that ends in the same string. This simple logic should be pretty similar to the logic used by lynx and curl. Signed-off-by: Martin Storsjö <martin@martin.st>
