* lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.
* 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>
* 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.

* Expose metadata found in onCuePoint events in .flv files.Andrew Stone2014-08-13
| | | | | | | | | | | | | | | | Currently, only onMetaData is used, but some providers (wrongly) put metadata into onCuePoint events, and it's still nice to be able to use that data. onCuePoint events also present metadata slightly differently than onMetaData events: all metadata is found inside an object called "parameters". In order to extract this metadata, it's easiest to recurse through the object tree and pull out anything found in child objects and put it in the top-level metadata.

* flv: Index the audio streamLuca Barbato2014-08-01
| | | | | And leverage the video index if the video is just disabled as wm4 did in an initial patch.
* flvdec: Do not default to a video and audio streamUwe L. Korn2014-06-01
| | | | | | | | | If no streams were indicated in the FLV header, do not automatically allocate by default a video and an audio stream. Instead, in the case that the header did not indicate the presence of any data, allocate no stream until data actually arrives for one type. Signed-off-by: Martin Storsjö <martin@martin.st>

* flv: Workaround for buggy Omnia A/XE encoderBenjamin Larsson2014-01-11
| | | | | | | | | The Omnia A/XE encoder writes the explicit extra data incorrectly and wrongly disables parametric stereo. Truncating the extra data by setting the size to 2 works around this. The AAC extra data parser will then only parse the correct parts. Bug-id: 599

* flvdec: Check the return value of a mallocMartin Storsjö2013-03-02
| | | | | | | | | | The callers of this function can't report errors sanely.

* flvdec: Make sure sample_rate is set to the updated valueMartin Storsjö2012-05-23
| | | | | | | | | | | | | | | | The sample_rate variable is used for checks for audio format changes at the end of the function. This fixes cases where the sample rate was set from the codec id by flv_set_audio_codec (as for nellymoser 8 kHz/16 kHz), so the value set to last_sample_rate wasn't equal to sample_rate at this point. This caused the demuxer otherwise reports a spurious change to 5512 Hz and back to the correct one. Updating channels in the same way is only done for consistency. Currently, flv_set_audio_codec doesn't update that value. Signed-off-by: Martin Storsjö <martin@martin.st>

* flvdec: Validate index entries added from metadata while readingMartin Storsjö2012-02-27
| | | | | | | | | | | By validating the index entries while reading, we don't need to seek at startup to validate the entries. If the error in the index entries is not pointing to (our definition of) the start of packets, and there is an index entry pointing at some of the first packets after the metadata, the invalid index can be discarded almost immediately.
