* lavf: switch to AVStream.time_base as the hint for the muxer timebaseAnton Khirnov2014-06-18
| | | | | | | | | | | | 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).

* mux: drop one of the hacks comprising compute_pkt_fields2()Anton Khirnov2014-05-19
| | | | All encoders should output proper timestamps now.
* lavf: drop the zero-sized packets hackAnton Khirnov2014-05-15
| | | | | | There should not be any valid reason anymore for passing completely empty packets to lavf. OTOH side data-only packets can be useful.
* lavf: add AVFMT_FLAG_BITEXACT.Anton Khirnov2014-05-15
| | | | | | | | Use it instead of checking CODEC_FLAG_BITEXACT in the first stream's codec context. Using codec options inside lavf is fragile and can easily break when the muxing codec context is not the encoding context.

* lavf: improve handling of sparse streams when muxingLuca Barbato2014-02-04
| | | | | | | | | | | | | | | | | | Currently ff_interleave_packet_per_dts() waits until it gets a frame for each stream before outputting packets in interleaved order. Sparse streams (i.e. streams with much fewer packets than the other streams, like subtitles or audio with DTX) tend to add up latency and in specific cases end up allocating a large amount of memory. Emit the top packet from the packet_buffer if it has a time delta larger than a specified threshold. Original report of the issue and initial proposed solution by mus.svz@gmail.com.

* lavf: ignore attachment streams for interleaving purposesAnton Khirnov2014-02-04
| | | | Those streams should never get any packets by definition.
* lavf: do basic sanity checking on muxed packetsAnton Khirnov2014-02-04
| | | | Reject packets for non-existing or attachment streams.
* lavf: Add a flag to enable/disable per-packet flushingLuca Barbato2013-09-16
| | | | | | | | | This is enabled by default and can be disabled with "-fflags -flush_packets". Inspired by a patch from Nicolas George <nicolas.george@normalesup.org>. Signed-off-by: Martin Storsjö <martin@martin.st>
