* avformat/segment: remove last_cut check when detecting a new segmentMarton Balint2017-02-04
| | | | | | | | | Not starting a new segment if the elapsed microsecs since the start of the day equals the the elapsed microsecs since the start of the day at the time of the last cut seems plain wrong to me, Deti do you remember the original reason behind this check?

* lavf/segment: fix crash when failing to open segment listRodger Combs2017-01-23
| | | | | | | | | | | | | | | This happens because segment_end() returns an error, so seg_write_packet never proceeds to segment_start(), and seg->avf->pb is never re-set, so we crash with a null pb when av_write_trailer flushes the packet queue. This doesn't seem to be clearly recoverable, so I'm just failing more gracefully. Repro: ffmpeg -i input.ts -f segment -c copy -segment_list /noaxx.m3u8 test-%05d.ts (assuming you don't have write access to /)

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

| * lavf: allow custom IO for all filesAnton Khirnov2016-01-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Some (de)muxers open additional files beyond the main IO context. Currently, they call avio_open() directly, which prevents the caller from using custom IO for such streams. This commit adds callbacks to AVFormatContext that default to avio_open2()/avio_close(), but can be overridden by the caller. All muxers and demuxers using AVIO are switched to using those callbacks instead of calling avio_open()/avio_close() directly. (de)muxers that use the URLProtocol layer directly instead of AVIO remain unconverted for now. This should be fixed in later commits.

* | lavf/segment: add new option segment_clocktime_wrap_durationMarton Balint2016-01-28
| | | | | | | | | | | | | | | | | | | | This option can force the segmenter to only start a new segment if a packet reaches the muxer within the specified duration after the segmenting clock time, which makes it more resilient to backward local time jumps, such as leap seconds or transition to standard time from daylight savings time.
