Anton Khirnov	5d58a35f98	fftools/ffmpeg: deprecate the -top option It is badly named (should have been -top_field_first, or at least -tff), underdocumented and underspecified, and (most importantly) entirely redundant with the setfield filter.	1 year ago
Anton Khirnov	3c397a1d46	fftools/ffmpeg: move sending filtergraph commands to a separate function Stop accessing filtergraph internals from keyboard reading code.	1 year ago
Anton Khirnov	bff48e8d69	fftools/ffmpeg_mux: rename of_close() to of_free() This function is primarily a destructor for OutputFile, the underlying AVIOContext is normally closed earlier (right after writing the trailer).	1 year ago
Anton Khirnov	8ecbb1f9af	fftools/ffmpeg_mux: stop rescaling timestamps in of_streamcopy() This function converts packet timestamps from the input stream timebase to OutputStream.mux_timebase, which may or may not be equal to the actual output AVStream timebase (and even when it is, this may not always be the optimal choice due to bitstream filtering). Just keep the timestamps in input stream timebase, they will be rescaled as needed before bitstream filtering and/or sending the packet to the muxer. Move the av_rescale_delta() call for audio (needed to preserve accuracy with coarse demuxer timebases) to write_packet. Drop now-unused OutputStream.mux_timebase.	1 year ago
Anton Khirnov	83ace80bfd	fftools/ffmpeg: return an error from MATCH_PER_STREAM_OPT() instead of aborting	1 year ago
Anton Khirnov	2f155b18a1	fftools/ffmpeg: return an error from assert_avoptions() instead of aborting Rename it to check_avoptions().	1 year ago
Anton Khirnov	6c6f13baf3	fftools/ffmpeg: return errors from find_codec_or_die() instead of aborting Rename the function to just find_codec().	1 year ago
Anton Khirnov	26e1e80152	fftools/ffmpeg_opt: reimplement -streamid using a dictionary This does not require an arbitrary limit on the number of streams. Also, return error codes from opt_streamid() instead of aborting.	1 year ago
Anton Khirnov	5ba7aa2ce8	fftools/ffmpeg_filter: return error codes from fg_create() instead of aborting	1 year ago
Anton Khirnov	8815adfe75	fftools/ffmpeg_filter: replace remaining exit_program() with error codes	1 year ago
Anton Khirnov	ab16e324ea	fftools/ffmpeg_filter: return error codes from ofilter_bind_ost() instead of aborting	1 year ago
Anton Khirnov	e0f4259689	fftools/ffmpeg_mux: return errors from of_output_packet() instead of aborting	1 year ago
Anton Khirnov	43bcf631d0	fftools/ffmpeg_enc: return errors from enc_flush() instead of aborting	1 year ago
Anton Khirnov	80a64800ea	fftools/ffmpeg_enc: return errors from enc_frame() instead of aborting	1 year ago
Anton Khirnov	3a89e6d352	fftools/ffmpeg_filter: restrict reap_filters() to a single filtergraph This is more natural, as all except one of its callers require processing only one filtergraph.	1 year ago
Anton Khirnov	dff3a283cd	fftools/ffmpeg: rework -enc_time_base handling Read the timebase from FrameData rather than the input stream. This should fix #10393 and generally be more reliable. Replace the use of '-1' to indicate demuxing timebase with the string 'demux'. Also allow to request filter timebase with '-enc_time_base filter'.	1 year ago
Anton Khirnov	4d06742b93	fftools/ffmpeg: add more structure to FrameData It now contains data from multiple sources, so group those items that always come from the decoder. Also, initialize them to invalid values, so that frames that did not originate from a decoder can be distinguished.	1 year ago
Anton Khirnov	75d0af388f	fftools/ffmpeg_filter: make OutputFilter.filter private It should not be accessed from outside of filtering code.	1 year ago
Anton Khirnov	c328bff4da	fftools/ffmpeg_enc: return errors from enc_subtitle() instead of aborting	1 year ago
Anton Khirnov	2e742a2c3c	fftools/ffmpeg_mux: return errors from of_streamcopy() instead of aborting	1 year ago
Anton Khirnov	cce294638b	fftools/ffmpeg: return errors from assert_file_overwrite() instead of aborting	1 year ago
Anton Khirnov	432399780a	fftools/ffmpeg_filter: make OutputFile.{formats,ch_layouts,sample_rates} private They are not used outside of the filtering code.	1 year ago
Anton Khirnov	a3ab5bf80d	fftools/ffmpeg_filter: make OutputFile.width,height private They are not used outside of the filtering code.	1 year ago
Anton Khirnov	c19aa9c28f	fftools/ffmpeg_filter: make OutputFile.ch_layout private It is not used outside of the filtering code.	1 year ago
Anton Khirnov	42f3f54cf4	fftools/ffmpeg_filter: make OutputFile.format/sample_rate private They are not used outside of the filtering code.	1 year ago
Anton Khirnov	88f80977eb	fftools/ffmpeg: use AVFrame to pass subtitles from decoders to filters Allows to use the same buffering code for all media types. Will also be important for the following commit.	1 year ago
Anton Khirnov	fa717baaa5	fftools/ffmpeg_enc: constify the subtitle passed to enc_subtitle()	1 year ago
Anton Khirnov	e89a6d1089	fftools/ffmpeg_dec: move InputStream.prev_sub to Decoder It does not need to be visible outside of decoding code.	1 year ago
Anton Khirnov	a45b9d35b9	fftools/ffmpeg: move fix_sub_duration_heartbeat() to ffmpeg_dec This way ffmpeg.c does not need to access InputStream.prev_sub and it can be made private.	1 year ago
Anton Khirnov	01897c1788	fftools/ffmpeg_dec: move decoding to a separate thread This is only a preparatory step to a fully threaded architecture and does not yet make decoding truly parallel - the main thread will currently submit a packet and wait until it has been fully processed by the decoding thread before moving on. Decoder behavior as observed by the rest of the program should remain unchanged. That will change in future commits after encoders and filters are moved to threads and a thread-aware scheduler is added.	1 year ago
Anton Khirnov	5293adb1a7	fftools/ffmpeg: attach bits_per_raw_sample information to frames This way avoids encoders reaching into filters or decoders for this information.	1 year ago
Anton Khirnov	1bdd53e2f9	fftools/ffmpeg_filter: make configure_filtergraph() static It is no longer used outside of ffmpeg_filter.	1 year ago
Anton Khirnov	a7aa05c599	fftools/ffmpeg_filter: add an AVClass to FilterGraph Use it for logging.	1 year ago
Anton Khirnov	1adad44fc7	fftools/ffmpeg_dec: move InputStream.hwaccel_pix_fmt to Decoder It is purely decoder-internal state.	1 year ago
Anton Khirnov	174cb3accf	fftools/ffmpeg_dec: remove pointless InputStream.hwaccel_retrieve_data It is always set to hwaccel_retrieve_data() from ffmpeg_hw.c, so that function can just be called directly instead.	1 year ago
Anton Khirnov	25d96ab6c0	fftools/ffmpeg_hw: inline hwaccel_decode_init() into its caller The function is now trivial and cannot fail, so all error handling in its caller can be removed.	1 year ago
Anton Khirnov	df81fb46ee	fftools/ffmpeg_dec: simplify process_subtitle() Its got_output argument always points to 1.	1 year ago
Anton Khirnov	e9eb44ed88	fftools/ffmpeg_dec: drop always-0 InputStream.prev_sub.ret	1 year ago
Anton Khirnov	141d11cb3c	fftools/ffmpeg_mux: make OutputStream.pkt private It is no longer used outside of muxing code.	1 year ago
Anton Khirnov	f94957e8f4	fftools/ffmpeg_mux: simplify calling of_output_packet() Use NULL packets to signal EOF instead of a separate variable. This is made possible by the previous commit.	1 year ago
Anton Khirnov	568d414074	fftools/ffmpeg: attach filter framerate to frames This way the encoder does not need to reach backward into the filter.	1 year ago
Anton Khirnov	9630341073	fftools/ffmpeg: factor out attaching FrameData to a frame Will be useful in following commits.	1 year ago
Anton Khirnov	ad14bdbcfd	fftools/ffmpeg_filter: drop a write-only variable	1 year ago
Anton Khirnov	ba1141d8a9	fftools/ffmpeg_enc: move nb_frames{dup,drop} globals into OutputStream	1 year ago
Anton Khirnov	2674532eee	fftools/ffmpeg_filter: constify the argument of filtergraph_is_simple()	1 year ago
Anton Khirnov	3bfc2c589a	fftools/ffmpeg_filter: make InputStream.filter private It is no longer accessed outside of ffmpeg_filter.	1 year ago
Anton Khirnov	5924b70075	fftools/ffmpeg_filter: make ifilter_has_all_input_formats() static It is no longer used outside ffmpeg_filter.	1 year ago
Anton Khirnov	f8abab673c	fftools/ffmpeg: move sub2video handling to ffmpeg_filter Make all relevant state per-filtergraph input, rather than per-input stream. Refactor the code to make it work and avoid leaking memory when a single subtitle stream is sent to multiple filters.	1 year ago
Anton Khirnov	a6d67b11f5	fftools/ffmpeg_filter: move sub2video subtitle queue to InputFilterPriv This queue should be associated with a specific filtergraph input - if a subtitle stream is sent to multiple filters then each should have its own queue.	1 year ago
Anton Khirnov	5d530e3a72	fftools/ffmpeg_dec: move sub2video submission to ffmpeg_filter This code is a sub2video analogue of ifilter_send_frame(), so it properly belongs to the filtering code. Note that using sub2video with more than one target for a given input subtitle stream is currently broken and this commit does not change that. It will be addressed in following commits.	1 year ago
