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
Anton Khirnov	3d35b73b2a	fftools/ffmpeg: constify AVSubtitle parameters as appropriate	1 year ago
Anton Khirnov	87b576135e	fftools/ffmpeg_filter: factor out binding an output stream to OutputFilter While the new function is trivial for now, it will become more useful in future commits.	1 year ago
Anton Khirnov	7ea10bfef3	fftools/ffmpeg_filter: store just the link label in OutputFilter Not the entire AVFilterInOut. This is simpler.	1 year ago
Anton Khirnov	da7ae627e1	fftools/ffmpeg_filter: always pass graph description to fg_create() Currently NULL would be passed for simple filtergraphs, which would make the filter code extract the graph description from the output stream when needed. This is unnecessarily convoluted.	1 year ago
Anton Khirnov	6abb4a28ef	fftools/ffmpeg: add InputStream.index This allows to avoid access to the underlying AVStream in many places.	1 year ago
Anton Khirnov	cad59cccaf	fftools/ffmpeg_dec: move timestamp estimation state to Decoder It is purely internal to decoding.	1 year ago
Anton Khirnov	5b05e9e32a	fftools/ffmpeg_dec: move InputStream.pkt to Decoder It is purely internal to decoding.	1 year ago
Anton Khirnov	dadeb28e25	fftools/ffmpeg_dec: add decoder private data Move InputStream.decoded_frame to it. Analogous to what has been previously done for all the other major components.	1 year ago
Anton Khirnov	f15b206286	fftools/ffmpeg_hw: move hw_device_setup_for_encode() to ffmpeg_enc This function is entangled with encoder setup, so it is more encoding code rather than ffmpeg_hw code. This will allow making more encoder state private in the future.	1 year ago
Anton Khirnov	760a9bd306	fftools/ffmpeg_hw: move hw_device_setup_for_decode() to ffmpeg_dec This function is entangled with decoder setup, so it is more decoding code rather than ffmpeg_hw code. This will allow making more decoder state private in the future.	1 year ago
Anton Khirnov	dbf1c6f5f1	fftools/ffmpeg: move decoding code to ffmpeg_dec	2 years ago
Anton Khirnov	4cec5ffc45	fftools/ffmpeg: rework handling -max_error_rate Replace the decode_error_stat global with a per-input-stream variable. Also, print an error message when the error rate is exceeded.	2 years ago
Anton Khirnov	4a59dde0c7	fftools/ffmpeg: eliminate InputStream.got_output It tracks whether the decoder for this stream ever produced any frames and its only use is for checking whether a filter input ever received a frame - those that did not are prioritized by the scheduler. This is awkward and unnecessarily complicated - checking whether the filtergraph input format is valid works just as well and does not require maintaining an extra variable.	2 years ago
Anton Khirnov	f980df2c04	fftools/ffmpeg_filter: move InputFilter.type to private data It is not accessed outside of ffmpeg_filter.	2 years ago
Anton Khirnov	c4a3f7edb8	fftools/ffmpeg_filter: move InputFilter.ist to private data It is not accessed outside of ffmpeg_filter.	2 years ago
