* mov: Do not compute negative SAR valuesVittorio Giovara2015-01-23
| | | | | | | | 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>

* dashenc: Fix format string generationRodger Combs2015-01-22
| | | | | | | Previously this always used the "lld" format for all parameters, not only time parameters. Signed-off-by: Martin Storsjö <martin@martin.st>
* smoothstreamingenc: Add a missing "goto fail"Michael Niedermayer2015-01-19
| | | | | | | | This goto wasn't necessary originally, but it should have been added when the write_manifest call was added in 8e276378. CC: libav-stable@libav.org Signed-off-by: Martin Storsjö <martin@martin.st>

* 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>
* id3v2: fix reading v2.2 attached picturesAnton Khirnov2015-01-14
| | | | | In v2.2, the picture type is not a zero-terminated string, but has a constant size of 3 bytes.
* id3v2: add names to the parameters of ID3v2EMFunc.readAnton Khirnov2015-01-14
| | | | Some of them are not immediately obvious.
* id3v2: constify the 'tag' parameter to special metadata parsing callbackAnton Khirnov2015-01-14
| | | | Those functions should not ever modify it.
* 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".

* img2dec: correctly use the parsed value from -start_numberVittorio Giovara2015-01-14
| | | | | | | Previously the image sequence was always starting from the minimum number rather than the requested one. CC: libav-stable@libav.org
* matroskaenc: refuse to write AAC without valid extradataAnton Khirnov2015-01-09

* mpeg: Remove unused fieldLuca Barbato2015-01-07

* segment: Fix the failure pathsLuca Barbato2015-01-07
| | | | | | | | | A failure in segment_end() or segment_start() would lead to freeing a dangling pointer and in general further calls to seg_write_packet() or to seg_write_trailer() would have the same faulty behaviour. CC: libav-stable@libav.org Reported-By: luodalongde@gmail.com

* libavformat: Remove a misleading/incorrect commentMartin Storsjö2015-01-04
| | | | | | | | This comment can be traced back to the initial commit from 2001, and it seemed to be misleading/incorect already back then. (It was used for normal, non-raw file formats already then.) Signed-off-by: Martin Storsjö <martin@martin.st>
* avisynth: Use RTLD_LOCAL instead of RTLD_GLOBALMartin Storsjö2015-01-03

* 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: Get rid of a hack for updating the dvc1 atomMartin Storsjö2015-01-03
| | | | | | | Use the more generic approach with the delay_moov flag, instead of having a update mechanism specific to this one single atom. 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>

| | | | | | | | When writing an explicit time, reset the cur_time variable to this value as well. This avoids writing excessive time attributes for each segment in the timeline, as long as the segments are continuous. Signed-off-by: Martin Storsjö <martin@martin.st>

* libavformat: Only use MoveFileExA when targeting the desktop API subsetMartin Storsjö2014-12-19
| | | | | | | | | | | | | | | | The MoveFileExA is available in the headers regardless which API subset is targeted, but it is missing in the Windows Phone link libraries. When targeting Windows Store apps, the function is available both in the headers and in the link libraries, and thus there is no indication for the build system that this function should be avoided - such an indication is only given by the Windows App Certification Kit, which forbids using the MoveFileExA function. Therefore check the WINAPI_FAMILY defines instead, to figure out which API subset is targeted. Signed-off-by: Martin Storsjö <martin@martin.st>

* libavformat: Add a muxer wrapping mpegts encoding into RTPMartin Storsjö2014-12-18
| | | | | | | | | | | | | | | Since this structurally is quite different from normal RTP (multiple streams are muxed into one single mpegts stream, which is packetized into one single RTP session), it is kept as a separate muxer. Since this structurally also behaves differently than normal RTP, all of the other muxers that do chained RTP muxing (rtsp, sap, mp4) would need to be updated similarly to handle this - in particular, creating one single rtp_mpegts muxer for the whole presentation instead of one rtp muxer per stream.

* rtp: Initial H.261 supportThomas Volkert2014-12-18
| | | | | | | | | | | | | | The packetizer only supports splitting at GOB headers - if such aren't available frequently enough, it splits at any random byte offset (not at a macroblock boundary either, which would be allowed by the spec) and sends a payload header pretend that it starts with a GOB header. As long as a receiver doesn't try to handle such cases cleverly but just drops broken frames, this shouldn't matter too much in practice. Signed-off-by: Martin Storsjö <martin@martin.st>
* rtpenc: Avoid brittle switch fallthroughsMartin Storsjö2014-12-18
| | | | | | | | | Instead explicitly jump to the default case in the cases where it is wanted, and avoid fallthrough between different codecs, which could easily introduce bugs if people editing the code aren't careful. Signed-off-by: Martin Storsjö <martin@martin.st>

* rtpenc: Set the AVFMT_TS_NONSTRICT flagMartin Storsjö2014-12-18
| | | | | | | | In particular, when packetizing mpegts into rtp, the input packet timestamp may come from more than one stream, which could cause multiple packets be written with the same timestamp. Signed-off-by: Martin Storsjö <martin@martin.st>
