* lavf: move internal fields from public to internal contextwm42015-02-10
| | | | | | | This is not an API change; the fields were explicitly declared private before. Signed-off-by: Anton Khirnov <anton@khirnov.net>
* mpegts: relax restrictions on matching the packet start in read_headerAnton Khirnov2015-02-10
| | | | | | | | | | | analyze() is currently called both when probing and from read_header(). It determines the packet start by looking for the sync byte, followed by unset Transport Error Indicator and valid adaptation_field_control. This makes sense to do when probing, but once we already know the format is MPEG-TS, it is counterproductive to be so strict -- e.g. in some files the TEI might be set and analyze() might get called with a smaller buffer than the one used for probing, resulting in a failure.
* lavf: remove unused codewm42015-02-08
| | | | | | | | | | | | | Nothing uses it, and it provides no public API. Archeological finds: Commit 101036adb9 added the API. Commit a8dd8dc6e9 made mpegts.c use it. Commit af8aae3fa3 disabled it by default in mpegts.c. Commit ae2bb52cd2 removed all uses of this from mpegts.c. Signed-off-by: Anton Khirnov <anton@khirnov.net>

* mov: Implement parsing of the "HandlerName" from the MP4 HDLR atomHendrik Leppkes2015-02-03
| | | | | | | | | | | | | | | | | This atom typically is used for a track title. The handler name is stored as a Pascal string in the QT specs (first byte is the length of the string), so do not export it. A second length check based on the first character is added to avoid overwriting an already specified handler_name (it happens with YouTube videos for instance, the handler_name get masked), or specifying an empty string metadata. The Pascal string fix and the second length check are written by Clément Bœsch <clement.boesch@smartjog.com>.

* avio: Do not consider the end-of-buffer position validLuca Barbato2015-01-28
| | | | | | | | | | | | | | Trigger a refill if the seek action moves the pointer at the end of the buffer. Before this patch the read action following the seek would trigger the refill, while write action would write outside the buffer. In the Libav codebase few muxers seek forward outside of what already has been written so it is quite unlikely to experience the problem with the default buffer size. CC: libav-stable@libav.org

| | | | | | | | This partially reverts cf70ba37ba74089a18295b29e77dead0a3222c9e, since it didn't take into account when rotation is 0, but there is another valid operation (eg. translation) in the matrix. Found-by: Michael Niedermayer <michaelni@gmx.at>

* rtmppkt: Repeat the full 32 bit timestamp for chunking continuation packetsMartin Storsjö2015-01-15
| | | | | | | | | | | | | | | | | | This fixes sending chunked packets (packets larger than the output chunk size, which often can be e.g. 4096 bytes) with a timestamp delta (or absolute timstamp, if it's a timestamp step backwards, or the first packet of the stream) larger than 0xffffffff. The RTMP spec explicitly says (in section 5.3.1.3.) that packets of type 3 (continuation packets) should include this field, if the previous non-continuation packet had it included. The receiving code handles these packets correctly. Pointed out by Cheolho Park. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* mov: Check angle rather than full matrix when updating SARVittorio Giovara2015-01-14
| | | | | | | | | | | | When the display matrix is not the identity one, but the rotation angle is zero, there is no need to update the sample aspect ratio. Otherwise, it is possible to obtain negative values which interferes with transcoding in later stages. This kind of behaviour is reproducible on mov files with "major_brand: MSNV".

* dashenc: Use pts for MPD timeline timestampsMartin Storsjö2015-01-03
| | | | | | | | | | | | | | | This should be more correct. This also should give more sensible switching between video streams with different amount of b-frame delay. The current dash.js release (1.2.0) fails to start playback of such files from the start (if the start pts is > 0), but this has been fixed in the current git version of dash.js. Also enable the use of edit lists, so that streams in many cases start at pts=0. Signed-off-by: Martin Storsjö <martin@martin.st>

* movenc: Add an option for delaying writing the moov with empty_moovMartin Storsjö2015-01-03
| | | | | | | | | | | | | | | | | | | | | | | | | This delays writing the moov until the first fragment is written, or can be flushed by the caller explicitly when wanted. If the first sample in all streams is available at this point, we can write a proper editlist at this point, allowing streams to start at something else than dts=0. For AC3 and DNXHD, a packet is needed in order to write the moov header properly. This isn't added to the normal behaviour for empty_moov, since the behaviour that ftyp+moov is written during avformat_write_header would be changed. Callers that split the output stream into header+segments (either by flushing manually, with the custom_frag flag set, or by just differentiating between data written during avformat_write_header and the rest) will need to be adjusted to take this option into use. For handling streams that start at something else than dts=0, an alternative would be to use different kinds of heuristics for guessing the start dts (using AVCodecContext delay or has_b_frames together with the frame rate), but this is not reliable and doesn't necessarily work well with stream copy, and wouldn't work for getting the right initialization data for AC3 or DNXHD either.

* movenc: Use start_dts/cts instead of cluster[0] for writing edit listsMartin Storsjö2015-01-03
| | | | | | | This allows writing edit lists even when track->entry == 0, if the start times have been set. Signed-off-by: Martin Storsjö <martin@martin.st>
* movenc: Remove an unnecessary condition when flushing fragmentsMartin Storsjö2015-01-03
| | | | | | | | | | | If fragments == 0 it means we haven't written any moov atom yet. If the empty_moov flag is set, we already have written an empty moov atom at startup. Thus, the check for empty_moov is redundant. This is in preparation for allowing writing the moov atom later, even when using the empty moov flag. Signed-off-by: Martin Storsjö <martin@martin.st>
