* avfilter/avfilter: move enable_str expression parsing into avfilter_init_dict()Paul B Mahol2021-02-06
| | | | | | | | This ensures that needed arrays are always allocated and properly initialized. Previously if code would use only avfilter_init_dict() to set options for filters it would not allocate arrays for timeline processing thus it would crash if user supplied enable option for filter(s).

* | avfilter: take_samples: do not directly return frame when samples are skippedMuhammad Faiz2017-05-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Modifying data pointer when skipping samples may make it unaligned. Workaround for Ticket6349. This should fix the crash of ticket's testcase and a crash/regression with avxsynth (reported by Michael Niedermayer). Also change frame->nb_samples < max to frame->nb_samples <= max. This improves performance.

| * lavfi: Always propagate hw_frames_ctx through linksMark Thompson2016-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Also adds a new flag to mark filters which are aware of hwframes and will perform this task themselves, and marks all appropriate filters with this flag. This is required to allow software-mapped hardware frames to work, because we need to have the frames context available for any later mapping operation in the filter graph. The output from the filter graph should only propagate further to an encoder if the hardware format actually matches the visible format (mapped frames are valid here and have an hw_frames_ctx, but this should not be given to the encoder as its hardware context).
* | lavfi: make ff_framequeue_skip_samples() more useful.Nicolas George2017-01-29
| | | | | | | | | | | | | | | | | | | | Instead of just updating statistics and leaving the work to the call site, have it actually do the work. Also: skip the samples by updating the frame data pointers instead of moving the samples. More efficient and avoid writing into shared frames. Found-By: Muhammad Faiz <mfcc64@gmail.com>
