* lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.

* mov: Add an option to toggle dref openingDerek Buitenhuis2016-01-21
| | | | | | | | | This feature is mostly only used by NLE software, and is both of dubious value being enabled by default, and a possible security risk. Signed-off-by: Derek Buitenhuis <derek.buitenhuis@gmail.com> Signed-off-by: Luca Barbato <lu_zero@gentoo.org>
* flvdec: Add sanity checking of the last packet sizeMartin Storsjö2016-01-19
| | | | | | | | For http, this avoids spurious warnings about failed requests (e.g. HTTP error 416 Requested Range Not Satisfiable), if the last packet is truncated and the size read is bogus. Signed-off-by: Martin Storsjö <martin@martin.st>
* flvdec: perform duration search just onceMichael Niedermayer2016-01-19
| | | | | | | | When loading a truncated flv file, it would previously try to do a seek to the end of every packet read. For some input protocols (such as http), such repeated seek attempts are cripple the reading performance. Signed-off-by: Martin Storsjö <martin@martin.st>

* movenc-test: stop setting the GLOBAL_HEADER codec flagAnton Khirnov2016-01-12
| | | | | This test does no encoding, setting the flag was done just to silence the warning removed in the previous commit.
* mux: drop the warning about global headersAnton Khirnov2016-01-12
| | | | | The AVStream codec context is often not (and should not be) the actual encoding context, so this warning will be spurious in many cases.

* mpegtsenc: add flag to embed an AC-3 ES the DVB wayStefan Pöschel2015-12-14
| | | | | | | | | | | | | So far an AC-3 elementary stream is refered to in the PMT according to System A (ATSC). However System B (DVB) has a different way to signal an AC-3 ES within the PMT. This different way can be enabled by a new flag. The flag is more generally named 'system_b' as there are further differences between ATSC and DVB (e.g. the signalling of E-AC-3) which should then also be covered by it in the future.

* vocdec: do not create the stream in read_header()Anton Khirnov2015-12-12
| | | | | The stream parameters are not known until we read a packet, so postpone creating it until then.
* vocdec: put the code not shared with other demuxers under appropriate ifdefAnton Khirnov2015-12-12
|
* flvdec: do not create any streams in read_header()Anton Khirnov2015-12-12
| | | | | | | | | | | The current muxer behaviour is to create streams in read_header() based on the audio/video presence flags, but fill in the stream parameters later when we actually get some packets for them. This is rather shady, since other demuxers set the stream parameters immediately when the stream is created and do not touch the stream codec context after that. Change the flv demuxer to behave in the same way as other similar demuxers -- create the streams only when we get a packet for them.
* mp3dec: replace avpriv_mpa_decode_header with avpriv_mpegaudio_decode_headerAnton Khirnov2015-12-12
| | | | | The latter does not require a full AVCodecContext and still provides all the functionality needed here.
* mpegaudiodecheader: check the header in avpriv_mpegaudio_decode_headerAnton Khirnov2015-12-12
| | | | | | Almost all the places from which this function is called already check the header manually and in the two that don't (the mp3 muxer) the check should not cause any problems.

* ff_parse_specific_params: do not use AVCodecContext.frame_sizeAnton Khirnov2015-12-12
| | | | | | It will not be set unless the muxing codec context is also the encoding context, which is discouraged. When the frame size is not known from av_get_audio_frame_duration(), the fallback should still be good enough.
* rmenc: do not use AVCodecContext.frame_sizeAnton Khirnov2015-12-12
| | | | | | It will not be set if the stream codec context is not the encoding context. Use av_get_audio_frame_duration() instead, it should work for all audio codecs supported by the muxer.
* matroskadec: Fix sample_aspect_ratio for stereo matroska contentAaron Colwell2015-12-07
| | | | | | | | | matroskaenc applies divisors to the display width/height when generating stereo content. This patch adds the corresponding multipliers to matroskadec so that the original sample aspect ratio can be recovered.

| | | | | | Checking the codec context parameters to find out this information is far too unreliable to be useful, so it is safer to assume B-frames are always present.
