* | movtextdec: fix handling of UTF-8 subtitleswm42018-03-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Subtitles which contained styled UTF-8 subtitles (i.e. not just 7 bit ASCII characters) were not handled correctly. The spec mandates that styling start/end ranges are in "characters". It's not quite clear what a "character" is supposed to be, but maybe they mean unicode codepoints. FFmpeg's decoder treated the style ranges as byte idexes, which could lead to UTF-8 sequences being broken, and the common code dropping the whole subtitle line. Change this and count the codepoint instead. This also means that even if this is somehow wrong, the decoder won't break UTF-8 sequences anymore. The sample which led me to investigate this now appears to work correctly.
* | avcodec: add a subcharenc mode that disables UTF-8 checkwm42018-03-25
| | | | | | | | | | | | | | | | This is for applications which want to explicitly check for invalid UTF-8 manually, and take actions that are better than dropping invalid subtitles silently. (It's pretty much silent because sporadic avcodec error messages are so common that you can't reasonably display them in a prominent and meaningful way in a application GUI.)

* | avcodec/bsf: make sure the AVBSFInternal stored packet is reference countedJames Almer2018-03-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some bitstream filters may buffer said packet in their own contexts for latter use. The documentation for av_bsf_send_packet() doesn't forbid feeding it non-reference counted packets, which depending on the way said packets were internally buffered by the bsf it may result in the data described in them becoming invalid or unavailable at any time. This was the case with vp9_superframe after commit e1bc3f4396, which was then promptly fixed in 37f4a093f7 and 7a02b364b6. It is still the case even today with vp9_reorder_raw. With this change the bitstream filters will not have to worry how to store or consume the packets fed to them. Reviewed-by: wm4 <nfxjfg@googlemail.com> Signed-off-by: James Almer <jamrial@gmail.com>
