Anton Khirnov	ba32f28498	doc/examples/transcode: convert timestamps between filtering and encoding The timebases do not have to match.	1 year ago
Anton Khirnov	811b0e02be	doc/examples/transcode: stop using decoder's AVCodecContext.time_base 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.	1 year ago
Anton Khirnov	828d3b4432	doc/examples/transcode: set packet timebase for decoding It is recommended for callers to set it, though not required.	1 year ago
James Almer	ed3691338b	doc/examples/transcode_aac: use av_samples_alloc_array_and_samples to allocate the input samples buffer and pointers Fixes -Wuse-after-free warnings and simplifies code. Signed-off-by: James Almer <jamrial@gmail.com>	2 years ago

Stefano Sabatini	cd0d267b92	doc/examples/mux: rename alloc_picture to alloc_frame The new name is consistent with the updated API.	2 years ago
Marton Balint	2296078397	avutil/frame: deprecate AVFrame.coded_picture_number and display_picture_number 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>	2 years ago
Marton Balint	6b6f7db819	avcodec: add AVCodecContext.frame_num as 64 bit variant to frame_number 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>	2 years ago

Wenbin Chen	efe2b63c89	doc/examples: Add qsv_transcode example 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>	2 years ago

Andreas Rheinhardt	23cb87bb3c	doc/examples/muxing: Remove outdated comment This comment only applies to the scenario in which one uses the AVCodecContexts embedded in AVStreams.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.
