Anton Khirnov	d60d6d819d	fftools/ffmpeg: drop an always-false check	2 years ago
Anton Khirnov	8ee4365ad8	fftools/ffmpeg: only convert video frame pts if we have a frame Calling adjust_frame_pts_to_encoder_tb() with a NULL frame does not perform a meaningful action.	2 years ago
Anton Khirnov	617ea07c22	fftools/ffmpeg: call check_recording_time() with actual frame pts Not its estimated value that will not necessarily be used.	2 years ago
Anton Khirnov	86a71d6b3c	fftools/ffmpeg: stop calling adjust_frame_pts_to_encoder_tb() for audio Almost none of that function's complexity is useful for audio, it can be replaced by a simple av_rescale_q().	2 years ago
Anton Khirnov	a186360f27	fftools/ffmpeg: set AVFrame.time_base after filtering Makes it easier to track what timebase are the frame timestamps in and allows to stop accessing filters in code that shouldn't deal with filtering.	2 years ago
Anton Khirnov	d9534ec84e	fftools/ffmpeg: move logging filtered frame timestamps Do it right after the frame is received from the filtergraph. This is a more logical place for this and will simplify future commits.	2 years ago
Anton Khirnov	2fa2e146cc	fftools/ffmpeg: avoid storing full forced keyframe spec It is not needed after the spec is parsed. Also avoids ugly string comparisons for each video frame.	2 years ago
Anton Khirnov	334e52e094	fftools/ffmpeg: parse forced keyframes in of_open() Allows to remove the ugly of_get_chapters() wrapper.	2 years ago
Anton Khirnov	efe4423627	fftools/ffmpeg: store forced keyframe pts in AV_TIME_BASE_Q Rather than the encoder timebase. Since the times are parsed as microseconds, this will not reduce precision, except possibly when chapter times are used and the chapter timebase happens to be better aligned with the encoder timebase, which is unlikely. This will allow parsing the keyframe times earlier (before encoder timebase is known) in future commits.	2 years ago
Anton Khirnov	b1143330c8	fftools/ffmpeg: move force-keyframe-related vars to a separate struct There are 8 of them and they are typically used together. Allows to pass just this struct to forced_kf_apply(), which makes it clear that the rest of the OutputStream is not accessed there.	2 years ago
Anton Khirnov	630fbdcc52	fftools/ffmpeg: stop explicitly closing decoders It serves no purpose, they will be closed and freed in avcodec_free_context() called from ist_free().	2 years ago

Andreas Rheinhardt	b2d1a25816	swscale/utils: Derive range from YUVJ-pix-fmt only once Currently, it is done once per slice-thread, leading to one warning per slice-thread in case a YUVJ pixel format has been originally used. This also fixes the anomaly that said parameter are only updated for the user-facing context (whose values are retrievable via av_opt_get()) if slice-threading is not in use. Fixes ticket #9860.

Andreas Rheinhardt	8ee0711228	swscale/utils: Don't allocate AVFrames for slice contexts Only the parent context's AVFrames are ever used. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Andreas Rheinhardt	64ed1d40df	swscale/utils: Factor initializing single slice context out Initializing slice threads currently uses the function (sws_init_context()) that is also used for initializing user-facing contexts with the only difference being that nb_threads is set to one before initializing the slice contexts. Yet sws_init_context() also initializes lots of stuff that is not slice-dependent, i.e. (src\|dst)Range. This currently only works because the code sets these fields to the same values for all slice contexts. This is not nice; even worse, it entails that log messages are printed once per slice context (and therefore fill the screen). This commit lays the groundwork to fix this.
