* avformat/avc, mxfenc: Avoid allocation of H264 SPS structure, fix memleakAndreas Rheinhardt2020-06-26
| | | | | | | | | | | | | | | | | | | | | | Up until now, ff_avc_decode_sps would parse a SPS and return some properties from it in a freshly allocated structure. Yet said structure is very small and completely internal to libavformat, so there is no reason to use the heap for it. This commit therefore changes the function to return an int and to modify a caller-provided structure. This will also allow ff_avc_decode_sps to return better error codes in the future. It also fixes a memleak in mxfenc: If a packet contained multiple SPS, only the SPS structure belonging to the last SPS would be freed, the other ones would leak when the pointer is overwritten to point to the new SPS structure. Of course, without allocations there are no leaks. This is Coverity issue #1445194. Furthermore, the SPS structure has been renamed from H264SequenceParameterSet to H264SPS in order to avoid overlong lines.

* avformat/webvttdec: Accept \r as newlineAndreas Rheinhardt2020-06-26
| | | | | | | | | | | | | After parsing the end timestamp of a WebVTT cue block, the current code skips everything after the start of the timestamp that is not a \t, ' ' or \n and treats what is next as the start of a WebVTT cue settings list. Yet if there is no such list, but a single \r, this will skip a part of the cue payload (namely everything until the first occurence of \t, ' ' or \n) and treat what has not been skipped as the beginning of the WebVTT cue settings list that extends until the next \r or \n (or the end).

* avformat/av1: Avoid using dynamic buffer when assembling av1cAndreas Rheinhardt2020-06-26
| | | | | | | | | Given that AV1 only has exactly one sequence header, it is unnecessary to copy the content of said sequence header into an intermediate dynamic buffer; instead the sequence header can be copied from where it is in the input buffer.

* lavc/aac_ac3_parser: improve the raw AAC file bit rate calculationJun Zhao2020-06-26
| | | | | | | | | | | | | | | | | | | Now we just use one ADTS raw frame to calculate the bit rate, it's lead to a larger error when get the duration from bit rate, the improvement cumulate Nth ADTS frames to get the average bit rate. e,g used the command get the duration like: ffprobe -show_entries format=duration -i fate-suite/aac/foo.aac before this improvement dump the duration=2.173935 after this improvement dump the duration=1.979267 in fact, the real duration can be get by command like: ffmpeg -i fate-suite/aac/foo.aac -f null /dev/null with time=00:00:01.97 Also update the fate-adtstoasc_ticket3715.

* avfilter/zoompan: add in_time variableexwm2020-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | Currently, the zoompan filter exposes a 'time' variable (missing from docs) for use in the 'zoom', 'x', and 'y' expressions. This variable is perhaps better named 'out_time' as it represents the timestamp in seconds of each output frame produced by zoompan. This patch adds aliases 'out_time' and 'ot' for 'time'. This patch also adds an 'in_time' (alias 'it') variable that provides access to the timestamp in seconds of each input frame to the zoompan filter. This helps to design zoompan filters that depend on the input video timestamps. For example, it makes it easy to zoom in instantly for only some portion of a video. Both the 'out_time' and 'in_time' variables have been added in the documentation for zoompan. Example usage of 'in_time' in the zoompan filter to zoom in 2x for the first second of the input video and 1x for the rest: zoompan=z='if(between(in_time,0,1),2,1):d=1' V2: Fix zoompan filter documentation stating that the time variable would be NAN if the input timestamp is unknown. V3: Add 'it' alias for 'in_time. Add 'out_time' and 'ot' aliases for 'time'. Minor corrections to zoompan docs. Signed-off-by: exwm <thighsman@protonmail.com>

| | | | | | | | | | | | | | | | | | | Commits 957a593cd95b15a5dcb2f50306fbac59f09d8e9e and 11828b8885cc1d87ffc7b1b4bbe642ce9720b194 made the flv demuxer export a certain flag as side data to be used by the nellymoser decoder for mid-stream sample rate changes. It used a custom side data type 'F' that was never officially documented. Yet since 2215c39e94e01f57b3191a29e0e51d7e230daf49 (merged in commit 52c522c72090233edeeb0486a9bd8bee925a710a) this information is exported via the properly documented AV_PKT_DATA_PARAM_CHANGE side data. The merge commit therefore stopped exporting the 'F' sidedata; yet the changes in the Nellymoser decoder (which are now dead code (and would become dangerous if lots of new side data types were added)) have not been removed. This commit does this. Reviewed-by: Anton Khirnov <anton@khirnov.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
