* | mpegts: stop analyzing when pmt for all programs have been foundJoakim Plate2013-12-151-9/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This disables NOHEADER after finding PMT for all programs to avoid find_stream_info always exhausting probe size for mpegts. This is very important for live streams since read speed will be limited. rtsp, udp and any protocol streaming a live mpegts will have dramatically faster startup time. Note, lack of codec parameters for streams can still cause the full probe size to be exhausted. Signed-off-by: Michael Niedermayer <michaelni@gmx.at>

| | | | | | | | | | | | | | | | | | | | | | | | | | When a stream contains a single program, there's no point in doing a PID -> program lookup.

* | mpegts: add fix_teletext_pts mpegts demuxer optionMarton Balint2013-08-061-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Changes since v1 of the patch: - enable option by default - add documentation - move up PTS override code after PES header parsing, to ensure we use the last PCR before the first packet of the teletext PES packet. The option overrides teletext packet PTS and DTS values with the timestamps calculated from the PCR of the first program which the teletext stream is part of and is not discarded. Using the same teletext PID for multiple programs is possible, therefore we need some kind of heuristics to know which program PCR we should synchronize to. Using the first non-discarded PCR pid among the programs of the teletext stream seemed like a good choice. The patch does not do PCR interpolation to estimate the PCR of the teltetext packet, it just uses the last PCR of the program, which may cause a slight error (0.1 sec) in the teletext packet pts-es.
