* examples/transcode: flush decoder on EOFZhao Zhili2023-08-261-2/+29

* examples: fix build of mux and resample_audioSebastian Ramacher2023-07-281-2/+2
| | | | | | | | | The commits eac4324bfbe452f0292b48b2f1dc37b5052ec0be and cd8211527efbb9cad19db1c0d033da0749836e43 renamed the examples, but the targets were not updated. Hence, the builds are missing -lm. Signed-off-by: Sebastian Ramacher <sramacher@debian.org> Signed-off-by: James Almer <jamrial@gmail.com>
* doc/examples/transcode: convert timestamps between filtering and encodingAnton Khirnov2023-06-031-0/+5
| | | | The timebases do not have to match.
* 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.
* doc/examples/transcode: set packet timebase for decodingAnton Khirnov2023-06-031-0/+5
| | | | It is recommended for callers to set it, though not required.

* doc/examples/mux: rename alloc_picture to alloc_frameStefano Sabatini2023-03-121-12/+12
| | | | The new name is consistent with the updated API.
* 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>

| | | | | | | | | | | | | | | | | | | Add qsv_transcode example which shows how to use qsv to do hardware accelerated transcoding, also show how to dynamically set encoding parameters. examples: Normal usage: qsv_transcode input.mp4 h264_qsv output.mp4 "g 60" Dynamic setting usage: qsv_transcode input.mp4 hevc_qsv output.mp4 "g 60 asyne_depth 1" 100 "g 120" This command initializes codec with gop_size 60 and change it to 120 after 100 frames Signed-off-by: Wenbin Chen <wenbin.chen@intel.com> Signed-off-by: Haihao Xiang <haihao.xiang@intel.com>

* doc/examples/muxing: Remove outdated commentAndreas Rheinhardt2022-03-251-4/+0
| | | | | | | | | | 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.
