5fd1dce39a avcodec/mpeg4videodec: Remove use of FF_PROFILE_MPEG4_SIMPLE_STUDIO as indicator of studio profile
The profile field is changed by code inside and outside the decoder,
its not a reliable indicator of the internal codec state.
Maintaining it consistency with studio_profile is messy.
Its easier to just avoid it and use only studio_profile

acb7907319 ffmpeg: fix -stream_loop with multiple inputs
The input thread needs to be properly cleaned up and re-initalized before we
can start reading again in threaded mode. (Threaded input reading is used when
there is mode than one input file).

Fixes ticket #6121 and #7043.

b5106c5aa2 avformat/mpegts: parse large PMTs with multiple tables
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.

meant as an optimization but is not necessary.

f0e4bc61e3 avformat/movenc: fix recognization of cover image streams
For chapter images, the mov demux produces streams with disposition set
to attached_pic+timed_thumbnails. This patch fixes to properly recognize
streams that should be encoded as cover image (ones with only and only
attached_pic disposition set).

36628bd215 avformat/movenc: properly handle cover image codecs
Find codec tag for attached images using appropriate list of
supported image formats.

This fixes writing the cover image to m4v/m4a and other container
formats that do not allow these codecs as a track.

The reference software appears to use longs for 32bits and it uses int for nmeans
hinting that the intended maximum size was not 32bit.
