Anton Khirnov	2d59873fc1	fftools/ffmpeg_demux: add logging for -dump_attachment Makes it more clear what was written where.	1 year ago
Anton Khirnov	63e4e8e4f4	fftools/ffmpeg_demux: forward errors from dump_attachment() instead of aborting Also, check the return code of avio_close().	1 year ago
Anton Khirnov	ff0160cb37	fftools/ffmpeg_demux: drop a redundant avio_flush() It is immediately followed by avio_close(), which is documented to flush the buffers.	1 year ago
Anton Khirnov	ad80857a97	fftools/ffmpeg_demux: return errors from ifile_open() instead of aborting	1 year ago
Anton Khirnov	c313cdd70c	fftools/ffmpeg_mux_init: return errors from of_open() instead of aborting	1 year ago
Anton Khirnov	9a2335444b	fftools/ffmpeg_mux: forward EOF from the sync queue EOF from sq_receive() means no packets will ever be output by the sync queue. Since the muxing sync queue is always used by all interleaved (i.e. non-attachment) streams, this means no further packets can make it to the muxer and we can terminate muxing now.	1 year ago
Anton Khirnov	6a9d3f46c7	fftools/ffmpeg: drop an obsolete debug log The value it prints has not been cur_dts from lavf for a very long time, so it's misleading.	1 year ago
Anton Khirnov	57a42a714b	fftools/ffmpeg_filter: consolidate calling avfilter_graph_set_auto_convert() Do not call it from choose_pix_fmts(), as that function is not supposed to modify random filtergraph properties.	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	c9a99ffe51	fftools/ffmpeg_filter: make sure no input or output is bound twice	1 year ago
Marton Balint	7357012bb5	fftools/ffmpeg: fix negative timestamps at the beginning of the encoding Also fix a couple of possible overflows while at it. Fixes the negative initial timestamps in ticket #10358. Signed-off-by: Marton Balint <cus@passwd.hu>	1 year ago
QiTong Li	79f41a0760	fftools/ffplay: fix typo in frame_queue_destory Not sure if the function naming frame_queue_destory is intended because "destory" is not really a word. Changing it to "destroy" makes more sense. Signed-off-by: QiTong Li <liqitong@163.com> Signed-off-by: Marton Balint <cus@passwd.hu>	1 year ago
James Almer	50f34172e0	fftools/ffplay: remove usage of internal AVInputFormat.read_seek field It's an internal field, so it should not be touched. Reviewed-by: Marton Balint <cus@passwd.hu> Signed-off-by: James Almer <jamrial@gmail.com>	1 year ago
Anton Khirnov	1617d1a752	fftools/ffmpeg: pass subtitle decoder dimensions to sub2video Restores behavior from before `20cacfe493`. Eventually this should be handled similarly to audio/video - with a filtergraph reset or a manual scaler.	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	7d4e00ccf0	fftools/ffmpeg_dec: stop using Decoder.pkt It is only used for flushing the subtitle decoder, so allocate a dedicated packet for that. Keep Decoder.pkt unused for now, it will be repurposed in future commits.	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	b1a213ab5d	fftools/ffmpeg_filter: reject filtergraphs with zero outputs Nothing useful can be done with them currently.	1 year ago
Anton Khirnov	a7aa05c599	fftools/ffmpeg_filter: add an AVClass to FilterGraph Use it for logging.	1 year ago
Anton Khirnov	a934392db0	fftools/ffmpeg_enc: move dup_warning global variable to Encoder	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	6c9cbf7507	fftools/ffmpeg_demux: reindent after previous commit	1 year ago
Anton Khirnov	98766dbbd7	fftools/ffmpeg_demux: move the loop out of add_input_streams() Make the function process just one input stream at a time and save an indentation level. Also rename it to ist_add() to be consistent with an analogous function in ffmpeg_mux_init.	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	730a2221af	fftools/ffmpeg_enc: use a private AVPacket instance for encoding The code currently uses OutputStream.pkt, which complicates its ownership semantics.	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	96e1325d91	fftools/ffmpeg_mux: use a dedicated packet for BSF output Currently of_output_packet() reuses the input packet, which requires its callers to submit blank packets even on EOF, which makes the code more complex.	1 year ago
Anton Khirnov	c803b36b8f	fftools/ffmpeg_enc: stop using OutputStream.initialized It is set by the muxing code, which will not be synchronized with encoding code after upcoming threading changes. Use an encoder-private variable instead.	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	d7781cfb95	fftools/ffmpeg: convert timestamps inside the muxer Packets submitted to the muxer now have their timebase attached to them, so the muxer can do conversion to muxing timebase and avoid exposing it to callers.	1 year ago
Anton Khirnov	cf121592c5	fftools/ffmpeg_mux_init: do not overwrite OutputStream.frame_rate for encoding The values currently written into it are not used after enc_open(), so it is better to confine them to that function.	1 year ago
Anton Khirnov	5bea8daa78	fftools/ffmpeg_enc: do not guess frame durations from output framerate There is no reason to expect input frame durations to match output framerate.	1 year ago
Anton Khirnov	2f92650c5d	fftools/ffmpeg_enc: inline init_encoder_time_base() into its callers The function now reduces to a ternary operator, so it is shorter and clearer to eliminate it.	1 year 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.	1 year ago
Anton Khirnov	58a64e3d54	fftools/ffmpeg_mux_init: only process -enc_time_base if the stream is encoded It has no effect otherwise.	1 year ago
Anton Khirnov	2baae6434b	fftools/ffmpeg_enc: merge two adjacent video-specific blocks There is no meaningful reason for them to be separated.	1 year 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.	1 year ago
