2025-10-15Disable use of stream IDs if there are duplicates, rather than rewriting.Carl Hetherington
It turns out that FFmpeg decoders (e.g. flv, see FFmpeg 25faaa311a74efdfdc4fed56996d7338ed807488) check stream IDs and sometimes create new streams if they see one that they didn't see before. If we change stream IDs we break this. Here we try to use stream indices in cases where the IDs are duplicated. We also account for the case where a new stream appears during examination. This wasn't covered by tests until the FFmpeg commit mentioned above, were the flv decoder creates a new stream during examination of boon_telly.mkv.

2024-11-01Needing length is the same for audio and video, so merge them.Carl Hetherington

2024-10-19Cleanup: initialise a few members in-place.Carl Hetherington
2024-10-19Tidy up and fix obtaining video length when it's not in the header.Carl Hetherington
I think this has been broken for a while as we would come out of the loop even if we still wanted to find the video length.
2024-02-21Make DCPExaminer::size() optional and deal with the consequences.v2.16.78Carl Hetherington
This means we can fix the case of a VF having no known size in a nice way, in turn fixing problems caused by the fix to #2775.

2022-01-11Use a separate AVFrame for each stream when decoding.Carl Hetherington
This seems to be what ffplay does and it feels like it makes sense as frames may be built from multiple packets AFAICS.

2020-08-02Detect soft 2:3 pulldown (telecine) files and decode them at 23.976.Carl Hetherington
DVD rips from NTSC DVDs are sometimes (always?) encoded using soft 2:3 pulldown. The video frames are actually 23.976 but FFmpeg detects them as 29.97. With the current approach of the video decoder ignoring most PTSs and assuming a constant frame rate it is vital that the file contains the number of frames per second that the detected frame rate predicts. This fixes large sync errors with NTSC DVD rips (#1790).

2016-05-18Partial work on using a no-video FFmpeg file.Carl Hetherington
2016-05-18Reasonably straightforward stuff; main things are addingCarl Hetherington
a _parent to VideoContent (mainly, but not only, for signalling) and moving the video shared_ptr into Content, which makes much more sense to replace dynamic_cast tests for whether something has video or whatever. Nearly builds.

2016-02-15Support SSA subtitles embedded within FFmpeg files.Carl Hetherington
2016-02-01Subtitle "to" times used to be stored against their "from" times.Carl Hetherington
Sadly an example shows that from times are not unique. This patch uses a hash of stuff from the first AVSubtitle as the key.
2015-11-13Disable YUV->RGB conversion controls with non-YUV sources (#649).Carl Hetherington
2015-09-25Fix assertion failure with .MTS files.Carl Hetherington
These files have subs which start but are never officially finished; this means there are no `to' times to find in find_subtitle_to. Cope with this by stopping the previous sub when a new one arrives if there hasn't been a proper "stop" in the mean time.
