Luca Barbato 0db6bbb24c avformat: Make avformat_free_context handle NULL
Work as the other free()-like functions.

Anton Khirnov 2d6e58497e lavf: switch to AVCodecContext.framerate for demuxing 2014-10-15 06:37:55 +00:00
Michael Niedermayer bd239c9a2e lavf: Don't drop both pts and dts if timestamps are invalid
In these cases, only drop dts. Because if we drop both we have no
timestamps at all for some files.

This improves playback of HLS streams from GoPro cameras.

Justin Ruggles 19133e96d3 lavf: fix memleaks in avformat_find_stream_info()
When AVFMT_FLAG_NOBUFFER is set, the packets are not added to the
AVFormatContext packet list, so they need to be freed when they are
no longer needed.

Anton Khirnov b263f8ffe7 lavf: add AVFormatContext.max_ts_probe
It allows to configure how long will avformat_find_stream_info() wait
to get the first timestamp.

Anton Khirnov 30e50c5027 lavf: eliminate ff_get_audio_frame_size()
It is basically a wrapper around av_get_audio_frame_duration(), with a
fallback to AVCodecContext.frame_size. However, that field is set only
when the stream codec context is actually used for encoding or decoding,
which is discouraged.

For muxing, it is generally the responsibility of the caller to set the
packet duration.
For demuxing, if the duration is not stored at the container level, it
should be set by the parser.

Therefore, removing the frame_size fallback should not break any
important case.

Andrew Stone 019d3fccc4 Set protocol-level metadata in AVFormatContext any time a packet is read.
If any option named "metadata" is set inside the context, it is pulled up to
the context and then the option is cleared.

Anton Khirnov 194be1f43e lavf: switch to AVStream.time_base as the hint for the muxer timebase
Previously, AVStream.codec.time_base was used for that purpose, which
was quite confusing for the callers. This change also opens the path for
removing AVStream.codec.

The change in the lavf-mkv test is due to the native timebase (1/1000)
being used instead of the default one (1/90000), so the packets are now
sent to the crc muxer in the same order in which they are demuxed
(previously some of them got reordered because of inexact timestamp
conversion).
