* examples/decode_filter_video: Add loop for draining the filtergraphTobias Rapp2024-03-281-0/+19
| | | | | | | | | Depending on the filters used, the filtergraph may produce trailing data after feeding it the last input frame. Update the example to include the necessary loop for draining the filtergraph. Reviewed-by: Stefano Sabatini <stefasab@gmail.com> Signed-off-by: Tobias Rapp <t.rapp@noa-archive.com>

* avutil/imgutils: Add wrapper for av_image_copy() to avoid castsAndreas Rheinhardt2023-09-121-3/+3
| | | | | | | | | | | | av_image_copy() accepts const uint8_t* const * as source; lots of user have uint8_t* const * and therefore either cast (the majority) or copy the array of pointers. This commit changes this by adding a static inline wrapper for av_image_copy() that casts between the two types so that we do not need to add casts everywhere else.

* doc/examples/transcode: stop using decoder's AVCodecContext.time_baseAnton Khirnov2023-06-031-5/+2
| | | | | | | | The contents of this field are not defined for decoding. Use pkt_timebase, which is the timebase of demuxed packets. Drop a tautological av_packet_rescale_ts() call, as the stream and decoder timebases are the same.

* avutil/frame: deprecate AVFrame.coded_picture_number and display_picture_numberMarton Balint2023-02-131-2/+2
| | | | | | | | Their usefulness is questionable, very few decoders set them, and their type should have been int64_t. A replacement field can be added later if a valid use case is found. Signed-off-by: Marton Balint <cus@passwd.hu>
* avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_numberMarton Balint2023-02-131-2/+2
| | | | | | | | | | Frame counters can overflow relatively easily (INT_MAX number of frames is slightly more than 1 year for 60 fps content), so make sure we use 64 bit values for them. Also deprecate the old 32 bit frame_number attribute. Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | | | | This comment only applies to the scenario in which one uses the AVCodecContexts embedded in AVStreams. Yet this code sample stopped doing so in 9897d9f4e074cdc6c7f2409885ddefe300f18dc7; and the last major version bump even removed the public AVCodecContexts in AVStreams. So just remove this comment.
