[FFmpeg-devel] [PATCH v20 13/20] fftools/ffmpeg: Replace sub2video with subtitle frame filtering and use new frame-based subtitle encoding API
Soft Works
softworkz at hotmail.com
Sun Dec 5 18:23:55 EET 2021
This commit actually enables subtitle filtering in ffmpeg by
sending and receiving subtitle frames to and from a filtergraph.
The heartbeat functionality from the previous sub2video implementation
is retained and applied to all subtitle frames (bitmap, text, ..).
The other part of sub2video functionality is retained by
auto-insertion of the new graphicsub2video filter.
Justification for changed test refs:
- sub2video
The new results are identical excepting the last frame which
is due to the implementation changes
- sub2video_basic
The previous results had some incorrect output because multiple
frames had the same dts
The non-empty content frames are visually identical, the different
CRC is due to the different blending algorithm that is being used.
- sub2video_time_limited
The third frame in the previous ref was a repetition, which doesn't
happen anymore with the new subtitle filtering.
- sub-dvb
Running ffprobe -show_frames on the source file shows that there
are 7 subtitle frames with 0 rects in the source at the start
and 2 at the end. This translates to the 14 and 4 additional
entries in the new test results.
- filter-overlay-dvdsub-2397
Overlay results have slightly different CRCs due to different
blending implementation
