Luca Barbato	d9ae1031f5	lavf: improve handling of sparse streams when muxing 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.

Anton Khirnov	33c859c142	lavf: ignore attachment streams for interleaving purposes Those streams should never get any packets by definition.	11 years ago
Anton Khirnov	7b03b65bf0	lavf: do basic sanity checking on muxed packets Reject packets for non-existing or attachment streams.	11 years ago
Luca Barbato	596e5d4783	lavf: Add a flag to enable/disable per-packet flushing 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>	11 years ago

Luca Barbato	c2cb01d418	lavf: introduce AVFMT_TS_NEGATIVE Most formats do not support negative timestamps, shift them to avoid unexpected behaviour and a number of bad crashes.
