Anton Khirnov	20c42213ea	fftools/ffmpeg_mux_init: drop an obsolete assignment This line was added in `c30a4489b4` along with AVStream.sample_aspect_ratio. However, configuring SAR for video encoding is now done after this code (specifically in enc_open(), which is called when the first video frame to be encoded is obtained), so this line cannot have any meaningful effect.	2 years ago
Anton Khirnov	858b635613	fftools/ffmpeg_mux_init: replace all remaining aborts with returning error codes Mainly concerns new_stream_*() and their callees.	2 years ago
Anton Khirnov	45473258ff	fftools/ffmpeg_mux_init: return error codes from metadata processing instead of aborting	2 years ago
Anton Khirnov	dd44871eb9	fftools/ffmpeg_mux_init: improve of_add_programs() Replace duplicated(!) and broken* custom string parsing with av_dict_parse_string(). Return error codes instead of aborting. * e.g. it treats NULL returned from av_get_token() as "separator not found", when in fact av_get_token() only returns NULL on memory allocation failure	2 years ago
Anton Khirnov	fd40197170	fftools/ffmpeg_mux_init: return error codes from validate_enc_avopt() instead of aborting	2 years ago
Anton Khirnov	4e3557aadb	fftools/ffmpeg_mux_init: return error codes from parse_forced_key_frames() instead of aborting	2 years ago
Anton Khirnov	6691d131d8	fftools/ffmpeg_mux_init: return error codes from copy_meta() instead of aborting	2 years ago
Anton Khirnov	54cbe6f57d	fftools/ffmpeg_mux_init: return error codes from ost_add() instead of aborting	2 years ago
Anton Khirnov	38a2fc2c29	fftools/ffmpeg_mux_init: move allocation out of prologue ost_add() has a very large variable declaration prologue, performing "active" actions that can fail in there is confusing.	2 years ago
Anton Khirnov	4e366100e9	fftools/ffmpeg_mux_init: return error codes from map_*() instead of aborting	2 years ago
Anton Khirnov	eee09cdf39	fftools/ffmpeg_mux_init: improve error handling in of_add_attachments() * return error codes instead of aborting * avoid leaking the AVIOContext on failure * check the return code of avio_read()	2 years ago
Anton Khirnov	b3eedca5e5	fftools/ffmpeg_mux_init: return errors from create_streams() instead of aborting	2 years ago
Anton Khirnov	cce294638b	fftools/ffmpeg: return errors from assert_file_overwrite() instead of aborting	2 years ago
Anton Khirnov	c313cdd70c	fftools/ffmpeg_mux_init: return errors from of_open() instead of aborting	2 years 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.	2 years ago
Anton Khirnov	141d11cb3c	fftools/ffmpeg_mux: make OutputStream.pkt private It is no longer used outside of muxing code.	2 years ago
Anton Khirnov	93e26a4db7	fftools/ffmpeg: handle -enc_time_base -1 during stream creation There is no reason to postpone it until opening the encoder. Also, abort when the input stream is unknown, rather than disregard an explicit request from the user.	2 years ago
Anton Khirnov	58a64e3d54	fftools/ffmpeg_mux_init: only process -enc_time_base if the stream is encoded It has no effect otherwise.	2 years ago
Anton Khirnov	c8a85d1b2f	fftools/ffmpeg_mux_init: do not overwrite OutputStream.frame_rate for streamcopy The values currently written into it are not used after streamcopy_init(), so it is better to confine them to that function.	2 years ago
Anton Khirnov	57021a68d9	fftools/ffmpeg_mux: set stream duration after the timebase is certainly known Stop assuming the encoder knows the muxing timebase, which does not always have to hold (e.g. due to bitstream filters).	2 years ago
Anton Khirnov	7520cd9f07	fftools/ffmpeg_mux_init: move OutputFilter setup code to ffmpeg_filter That is a more appropriate place for it.	2 years 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.	2 years ago
Anton Khirnov	7ea10bfef3	fftools/ffmpeg_filter: store just the link label in OutputFilter Not the entire AVFilterInOut. This is simpler.	2 years 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.	2 years ago
Anton Khirnov	b56db2956b	fftools/ffmpeg: add logging for creating output streams	2 years ago
Anton Khirnov	eeb7d92ac7	fftools/ffmpeg_mux_init: merge ost_add_from_filter() to ost_add() This way ost_add() knows about the complex filtergraph it is fed from, which will become useful in future commits.	2 years ago
Anton Khirnov	e9a868e9ee	fftools/sync_queue: add debug logging	2 years ago
Anton Khirnov	6abb4a28ef	fftools/ffmpeg: add InputStream.index This allows to avoid access to the underlying AVStream in many places.	2 years ago
Anton Khirnov	ec75b79fe1	fftools/ffmpeg: fail earlier on text/bitmap subtitles mismatch Checking whether the user requested an unsupported conversion between text and bitmap subtitles can be done immediately when creating the output stream.	2 years ago
Anton Khirnov	dfa29ba955	fftools/ffmpeg: return error codes from ist_*_add() Will be useful in future commits.	2 years ago
Anton Khirnov	09dd9c5f41	fftools/ffmpeg_filter: add filtergraph private data Start by moving OutputStream.filtered_frame to it, which really belongs to the filtergraph rather than the output stream.	2 years ago
Anton Khirnov	0add05bd3a	fftools/ffmpeg_mux_init: rename init_output_filter() to ost_add_from_filter() The previous name is misleading, because the function does not actually initialize any filters - it creates a new output stream and binds a filtergraph output to it.	2 years ago
Anton Khirnov	4800b50258	fftools/ffmpeg: simplify init_output_filter()	2 years ago
Anton Khirnov	ea4c42779b	fftools/ffmpeg_mux_init: drop a redundant assignment OutputFilter.format is initialized in ofilter_alloc().	2 years ago
Anton Khirnov	2104de13e9	fftools/ffmpeg: reindent after previous commit	2 years ago
Anton Khirnov	6cace17b0d	fftools/ffmpeg_mux_init: drop useless new_stream_{data,unknown} Their only function is checking that encoding was not specified for data/unknown-type streams, but the check is broken because enc_ctx will not be created in ost_add() unless a valid encoder can be found. Add an actually working check for all types for which encoding is not supported in choose_encoder().	2 years ago
Anton Khirnov	ab0d2052a3	fftools/ffmpeg: remove unused function arguments	2 years ago
Anton Khirnov	ecb44ca877	fftools/ffmpeg_mux_init: drop OutputStream.filters[_script] They are not needed outside of ost_get_filters(), so make them stack variables there.	2 years ago
Anton Khirnov	84e1e0fa73	fftools/ffmpeg_mux_init: move check for mixing simple/complex filters Do it in ost_get_filters() together with other similar checks. Will be useful in following commits. Also, improve the log message.	2 years ago
Anton Khirnov	0fe5eaf69d	fftools/ffmpeg_mux_init: consolidate handling -filter for audio/video	2 years ago
Anton Khirnov	30699c103f	fftools/ffmpeg_mux: make copy_initial_nonkeyframes private to muxing code It is no longer used outside of ffmpeg_mux*	2 years ago
Anton Khirnov	7f8827f28e	fftools/ffmpeg_mux: make copy_prior_start private to muxing code It is no longer used outside of ffmpeg_mux*	2 years ago
Anton Khirnov	83646146fe	fftools/ffmpeg_mux: make ts_copy_start private to muxing code It is no longer used outside of ffmpeg_mux*	2 years ago
Anton Khirnov	a34f483291	fftools/ffmpeg: add muxer-input codec parameters to OutputStream It stores codec parameters of the stream submitted to the muxer, which may be different from the codec parameters in AVStream due to bitstream filtering. This avoids the confusing back and forth synchronisation between the encoder, bitstream filters, and the muxer, now information flows only in one direction. It also reduces the need for non-muxing code to access AVStream.	2 years ago
Anton Khirnov	a064aed4c3	fftools/ffmpeg: store stream media type in OutputStream Reduces access to a deeply nested muxer property OutputStream.st->codecpar->codec_type for this fundamental and immutable stream property. Besides making the code shorter, this will allow making the AVStream (OutputStream.st) private to the muxer in the future.	2 years ago
Anton Khirnov	de38e17583	fftools/ffmpeg: initialize no-filter streams earlier There is no reason to postpone it until transcode_init() anymore, it can be done right at the end of of_open().	2 years ago
Anton Khirnov	ff92ecad2f	fftools/ffmpeg: stop setting InputStream fields from muxing/filtering code Set InputStream.decoding_needed/discard/etc. only from ist_{filter,output},add() functions. Reduces the knowledge of InputStream internals in muxing/filtering code.	2 years ago
Anton Khirnov	c7438e8737	fftools/ffmpeg_mux_init: consolidate input stream flagging code Makes it easier to see where the input stream is modified from muxer code.	2 years ago
Anton Khirnov	a0452ee837	fftools/ffmpeg_mux_init: remove a redundant check	2 years ago
Anton Khirnov	12f3f41bbf	fftools/ffmpeg: move init_output_stream_streamcopy() to ffmpeg_mux_init Everything in it can be done immediately when creating the output stream, there is no reason to postpone it.	2 years ago
