Anton Khirnov	425b2c4a56	fftools/ffmpeg: add options for writing encoding stats Similar to -vstats, but more flexible: - works for audio as well as video - frame and/or packet information - user-specifiable format	2 years ago
Anton Khirnov	7655249f72	fftools/ffmpeg: reindent after previous commit	2 years ago
Anton Khirnov	a848a5a223	fftools/ffmpeg: move video frame dup/drop logic into its own function	2 years ago
Anton Khirnov	5874ca3650	fftools/ffmpeg: rename a variable to be more descriptive	2 years ago
Anton Khirnov	3b21f10639	fftools/ffmpeg: fix stream id in an error message. Broken in `7ef7a22251`	2 years ago
Anton Khirnov	c60941dfaf	fftools/ffmpeg: stop using AVCodecContext.sample_rate in decode_audio() Use the decoded frame's sample_rate instead, which is the authoritative value. Drop a now-obsolete check validating AVCodecContext.sample_rate.	2 years ago
Marvin Scholz	f1907faab4	fftools: use av_dict_iterate Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>	2 years ago
Anton Khirnov	becbb22eb0	fftools/ffmpeg: cosmetics Reindent after previous commit and break/split some lines as appropriate.	2 years ago
Anton Khirnov	d04ec7efe3	fftools/ffmpeg: remove a useless inner block adjust_frame_pts_to_encoder_tb() is so small that this serves no useful purpose.	2 years ago
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
Anton Khirnov	996fed5235	fftools/ffmpeg: declare loop variables inside loops in transcode_init()	2 years ago
Anton Khirnov	005f4e1caf	fftools/ffmpeg: do not assume input streams exist There can be zero input streams, with input provided by lavfi complex filtergraphs.	2 years ago
Anton Khirnov	fd8bf8d3b5	fftools/ffmpeg: remove the input_streams global Replace it with an array of streams in each InputFile. This is a more accurate reflection of the actual relationship between InputStream and InputFile. Analogous to what was previously done to output streams in `7ef7a22251`.	2 years ago
Anton Khirnov	4c40581614	fftools/ffmpeg: replace OutputStream.source_index with a pointer to InputStream This is simpler. The indirection via an index exists for historical reasons that longer apply.	2 years ago
Anton Khirnov	bda06c60fe	fftools/ffmpeg: stop inventing fake source information This code was supposed to affect copying stream dispositions, but it does not achieve that after `bd55552d69`, since dispositions are set earlier.	2 years ago
Anton Khirnov	50ecba7e84	fftools/ffmpeg: drop an arbitrary condition Encoding init code will currently fall back to a 25fps default when no framerate is known or specified, but only if there is a known source input stream. There is no good reason for this condition, so drop it.	2 years ago
Anton Khirnov	9654df1336	fftools/ffmpeg: move freeing an input stream into a separate function	2 years ago
Anton Khirnov	25620b69e0	fftools/ffmpeg: stop handling max_frames in do_video_out() Frame limiting is now handled using sync queues. This code prevents the sync queue from triggering EOF, resulting in unnecessarily many frames being decoded, filtered, and then discarded. Found-by: U. Artie Eoff <ullysses.a.eoff@intel.com>	2 years ago
Anton Khirnov	1b076556c6	fftools/ffmpeg: simplify ost_iter() The inner loop never goes through more than 1 iteration, and so can be replaced by an if(). Found-by: Andreas Rheinhardt	2 years ago
Gyan Doshi	5ccd4d3060	ffmpeg: fix implementation of updated input start time The current adjustment of input start times just adjusts the tsoffset. And it does so, by resetting the tsoffset to nullify the new start time. This leads to breakage of -copyts, ignoring of input_ts_offset, breaking of -isync as well as breaking wrap correction. Fixed by taking cognizance of these parameters, and by correcting start times just before sync offsets are applied.	2 years ago
Gyan Doshi	93faba449c	ffmpeg: shift start time correction to ffmpeg_opt In preparation for applying start time correction that accounts for all factors such as copyts, input_ts_offset ..etc	2 years ago
Anton Khirnov	c20977c4e0	fftools/ffmpeg: drop free_input_threads() Stop demuxer threads in ifile_close() instead. Simplifies the demuxer API.	2 years ago
Anton Khirnov	295848bacb	fftools/ffmpeg: move closing the input file into a separate function For now this is just closing the format context and freeing InputFile, but will contain more in the future.	2 years ago
Anton Khirnov	09cd147dcc	fftools/ffmpeg: drop init_input_threads() Start threads implicitly when ifile_get_packet() is called. Simplifies the demuxer API.	2 years ago
Jan Ekström	b9058765d7	ffmpeg: Deprecate display rotation override with a metadata key Now that we have proper options for defining display matrix overrides, this should no longer be required. fftools does not have its own versioning, so for now the define is just set to 1 and disables the functionality if set to zero.	2 years ago
Anton Khirnov	709b47f8a4	fftools/ffmpeg: free output streams in of_close() Output streams are now children of OutputFile, so it makes more sense to free them there.	2 years ago
Anton Khirnov	fe304c0694	fftools/ffmpeg: remove a cleanup block at the end of transcode() Some of it is already duplicated in ost_free() - those parts can be just dropped. The rest is moved to ost_free(), as it properly belongs there.	2 years ago
Anton Khirnov	7ef7a22251	fftools/ffmpeg: remove the output_streams global Replace it with an array of streams in each OutputFile. This is a more accurate reflection of the actual relationship between OutputStream and OutputFile. This is easier to handle and will allow further simplifications in future commits.	2 years ago
Anton Khirnov	18d96e8703	fftools/ffmpeg: reindent after previous commit	2 years ago
Anton Khirnov	2dcedd9af8	fftools/ffmpeg: move freeing an output stream into a separate function	2 years ago
Anton Khirnov	9f9bf8703b	fftools/ffmpeg: move init_output_bsfs() to ffmpeg_mux Bitstream filtering is done as a part of muxing, so this is the more proper place for this.	2 years ago
Anton Khirnov	965bff37b6	fftools/ffmpeg: move some stream initialization code to ffmpeg_mux The code in question is muxing-specific and so belongs there. This will allow make some objects private to the muxer in future commits.	2 years ago
Anton Khirnov	d579a70291	fftools/ffmpeg: move output_packet() to ffmpeg_mux This function is common to both transcoding and streamcopy, so it properly belongs into the muxing code.	2 years ago
Anton Khirnov	044d70736e	fftools/ffmpeg: move some code from init_output_stream() to init_output_stream_encode() The code is subtitle-encoding-specific, so this is a more appropriate place for it.	2 years ago
Anton Khirnov	29188f9c62	fftools/ffmpeg: rename OutputStream.sync_opts to next_pts The current name is confusing.	2 years ago
Anton Khirnov	3c0f532cbc	fftools/ffmpeg: pass the timestamp to check_recording_time() Stop setting OutputStream.sync_opts for subtitle encoding, as it is now unused.	2 years ago
Anton Khirnov	69f770f77c	fftools/ffmpeg: stop setting OutputStream.sync_opts for streamcopy It is not used for anything.	2 years ago
Anton Khirnov	76678b7137	fftools/ffmpeg: drop never-set OutputStream.first_pts	2 years ago
Anton Khirnov	5188aeaffb	fftools/ffmpeg: cosmetics Reindent after previous commit, apply some style fixes.	2 years ago
Anton Khirnov	c75be06148	fftools/ffmpeg: move forced keyframe processing into its own function	2 years ago
