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.

Janne Grunau	78987a88a8	lavf: include 60 fps in guessed standard frame rates Due to what looks like an off-by-one error 60 * 12 * 1001 / 12 * 1001 is not tested as standard frame rate in avformat_find_stream_info().	11 years ago

Martin Storsjö	2aec9e228c	rtpdec_asf: Copy the need_parsing field from the chained demuxer This fixes playback of mp3 streams in rtp/asf. This used to work until `c6f1dc8`, but mostly by coincidence. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Martin Storsjö	89564be444	rtmpproto: Send a full, absolute timestamp if it isn't monotonically growing The normal differential timestamps can't handle negative differences, thus send a full packet header with an absolute timestamp in these cases.

Martin Storsjö	24eb3c7916	rtmpproto: Avoid using uninitialized memory If the url ends with .flv, we stripped it but didn't initialize rt->playpath, doing av_strlcat on an uninitialized buffer. Signed-off-by: Martin Storsjö <martin@martin.st>	11 years ago
Justin Ruggles	d01e684186	mov: do not set avg_frame_rate in the demuxer The track duration is often not reliable or is not the duration represented by the number of frames. In those cases, avg_frame_rate was reported incorrectly. Removing this code falls back to the default calculation in avformat_find_stream_info(). This is a partial revert of commit `c3aeaa540`.

Martin Storsjö	2620df1310	mov: Free an earlier allocated array if allocating a new one It could probably also be considered an error if the pointer isn't null at this point, but then we might risk rejecting some slightly broken files that we might have handled so far.

Martin Storsjö	d51f09962d	mov: Free intermediate arrays in the normal cleanup function These arrays are normally freed at the end of mov_read_trak, but make sure they're freed in case mov_read_trak returned early (due to errors) or in case the atoms that allocate arrays are encountered at some other point than within a trak (which we don't have checks against).
