* avformat/apngdec: set pts to AV_NOPTS_VALUEMarton Balint2018-07-02
| | | | | | | | | And let the generic code figure out the proper PTS. This is needed because apng does not provide seek functions, but after a generic seek (e.g. to file start) timestamps are not reset which causes broken timestamps when looping apngs, like in ticket #6121.

* avformat/movenc: read track title from correct keyGyan Doshi2018-06-19
| | | | | | | | | | da9cc22d5bd allowed the MOV muxer to relay a custom stream handler name, whether populated from the input stream or user-set. However, the entry key didn't match the key set by the MOV demuxer, so it wasn't effective. Fixed. Due to the change, four FATE refs have to be updated. Verified that the target payload of the tests hasn't changed in terms of CRC.
* avformat/mpegts: parse large PMTs with multiple tablesAman Gupta2018-06-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 9152c1e4955, the mpegts parser was taught how to parse PMT sections which contained multiple tables. That commit fixed parsing of PMT packets from some cable providers, which included a special SCTE table (0xc0) before the standard program map table (0x2). Sometimes, however, the combined 0xc0 and 0x2 tables are larger than a single TS packet (188 bytes). The mpegts parser already attempts to parse sections which span multiple packets, but still assumed that the split section only contained one table. This patch fixes parsing of such a sample[1]. Before: Input #0, mpegts, from 'combined-pmt-tids-split.ts': Duration: 00:00:01.26, start: 39188.931756, bitrate: 597 kb/s Program 1 No Program Stream #0:0[0xeff]: Audio: ac3, 48000 Hz, mono, fltp, 64 kb/s Stream #0:1[0xefd]: Audio: mp3, 0 channels, fltp Stream #0:2[0xefe]: Unknown: none After: Input #0, mpegts, from 'combined-pmt-tids-split.ts': Duration: 00:00:01.27, start: 39188.931756, bitrate: 589 kb/s Program 1 Stream #0:0[0xefd]: Video: h264 ([27][0][0][0] / 0x001B), none, 59.94 fps, 59.94 tbr, 90k tbn, 180k tbc Stream #0:1[0xefe](eng): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, stereo, fltp, 384 kb/s Stream #0:2[0xeff](spa): Audio: ac3 ([129][0][0][0] / 0x0081), 48000 Hz, mono, fltp, 64 kb/s Stream #0:3[0xf00]: Data: scte_35 Stream #0:4[0xf01]: Unknown: none (ETV1 / 0x31565445) Stream #0:5[0xf02]: Unknown: none (ETV1 / 0x31565445) Stream #0:6[0xf03]: Unknown: none ([192][0][0][0] / 0x00C0) With the patch, the PMT is parsed correctly so the streams are created in the correct order, are associated with "Program 1", and their codecs are set correctly.
