Anton Khirnov	f6772e9bf8	avconv: make sure the filtergraph is freed on init failure The filtergraph's existence is used in several places to mean that the filtergraph is fully configured. This causes problems if it's allocated, but the initialization fails (e.g. if a non-existent filter is specified).	8 years ago
Luca Barbato	602abe77b0	avconv: Check the fifo allocation	8 years ago
Anton Khirnov	b0f36a0043	avconv: stop using setpts for input framerate forced with -r The setpts filter does not signal to the rest of the filtergraph that the stream is CFR. Just generate the timestamps manually instead.	8 years ago
Anton Khirnov	94ebf55658	avconv: restructure sending EOF to filters Be more careful when an input stream encounters EOF when its filtergraph has not been configured yet. The current code would immediately mark the corresponding output streams as finished, while there may still be buffered frames waiting for frames to appear on other filtergraph inputs. This should fix the random FATE failures for complex filtergraph tests after `a3a0230a98`	9 years ago
Anton Khirnov	d2e56cf753	avconv: move flushing the queued frames to configure_filtergraph() This is a more appropriate place for it, and will also be useful in the following commit.	9 years ago
Mark Thompson	bd31c61cf9	avconv: Remove hw_device_ctx output filter reinit hack Not needed any more because we no longer have any useful case which will reinitialise with hardware frames here.	9 years ago
Anton Khirnov	a3a0230a98	avconv: init filtergraphs only after we have a frame on each input This makes sure the actual stream parameters are used, which is important mainly for hardware decoding+filtering cases, which would previously require various weird workarounds to handle the fact that a fake software graph has to be constructed, but never used. This should also improve behaviour in rare cases where avformat_find_stream_info() does not provide accurate information.	9 years ago
Anton Khirnov	50722b4f0c	avconv: decouple configuring filtergraphs and setting output parameters Currently, a filtergraph will pull in the output constraints from its corresponding decoder context, which breaks proper layering. Instead, explicitly send the constaints on the output parameters to the filtergraph. This is similar to what is done for filtergraph inputs in 30ab4c51a180610d9f1720c75518d763515c0d9f	9 years ago
Anton Khirnov	722ec3eb35	avconv: decouple configuring filtergraphs and setting input parameters Currently, calling configure_filtergraph() will pull in the input parameters from the corresponding decoder context. This has the following disadvantages: - the decoded frame is a more proper source for this information - a filter accessing decoder data breaks proper layering Add functions for explicitly sending the input stream parameters to a filtergraph input - currently from a frame and a decoder. The decoder one will be dropped in future commits after some more restructuring.	9 years ago
Anton Khirnov	73c6ec6d65	avconv: create simple filtergraphs earlier We already have all the necessary information in open_output_file(). This makes the information about the stream/filtergraph mappings available earlier.	9 years ago
Anton Khirnov	49670e4218	avconv: add a function for determining whether a filtergraph is simple This makes the code easier to read.	9 years ago
Mark Thompson	5d273d3efa	avconv: VAAPI hwcontext initialisation and hwaccel helper Signed-off-by: Anton Khirnov <anton@khirnov.net>	9 years ago
Anton Khirnov	15e84ed3f1	avconv: convert to codecpar The switch is not yet complete because the parsers and the bistream filters do not have a new AVCodecParam-based API yet.	9 years ago
Anton Khirnov	1bf3413461	avconv: use the new buffersrc parameters API The timebase change in the zmbv-8bit test is due to the fact that previously the timebase string was evaluated as floating point, then converted to a rational. After this commit, the timebase is passed directly as is.	9 years ago
Luca Barbato	8b830ee9a2	avconv: Do not try to configure filter outputs without streams Prevent a NULL-dereference. CC: libav-stable@libav.org	9 years ago
Vittorio Giovara	18adc1fd3b	avconv_filter: Use full named options This introduces a slight timebase computation difference in zmbv-8bit fate test. This is expected since the new options are double instead of ints, and the additional precision skews the results in a non meaningful way.	9 years ago
Anton Khirnov	6d592fbd0d	avconv: split creating and (re-)configuring complex filtergraphs The current code is less than straightforward due to the fact that output streams can be created based on filtergraph definitions. This change should make the code simpler and more readable. It will also be useful in the future commits.	9 years ago
Martin Storsjö	16302246b1	avconv: Add an option for automatically rotating video according to display matrix The option is enabled by default, but can be disabled. If this is enabled, such side data isn't copied into the output stream (except when doing stream copy). Signed-off-by: Martin Storsjö <martin@martin.st>	10 years ago

Vittorio Giovara	d28fc7b29a	avconv_filter: add new line after error message	11 years ago
Anton Khirnov	488a0fa689	avconv: support -t as an input option. It limits the duration of the data read from a given input.	11 years ago
Anton Khirnov	811bd07846	avconv: make input -ss accurate when transcoding Insert (a)trim filters on the corresponding inputs, so the extra frames are decoded and discarded.	11 years ago
Anton Khirnov	56ee3f9de7	avconv: distinguish between -ss 0 and -ss not being used Using -ss 0 to drop frames with negative timestamps is a perfectly valid use case.	11 years ago
Anton Khirnov	2e661f26f8	avconv: insert extra filters in the same way for both graph inputs and outputs This will allow using the same code when one filter can be inserted both on input and output.	11 years ago
Anton Khirnov	06cd4c5a68	avconv: fix usage of deprecated lavfi API	11 years ago
Anton Khirnov	51fc88e746	avconv: improve some variable names 'filter' is too generic, since the functions in question deal with several filters. Also add const qualifiers to those variables.	11 years ago
Luca Barbato	72fbc9685c	avconv: use current syntax for the scale filter	12 years ago
Anton Khirnov	8cd472d3f9	avconv: make output -ss insert trim/atrim filters. This makes output -ss sample-accurate for audio and will allow further simplication in the future.	12 years ago
Anton Khirnov	a83c0da539	avconv: make -t insert trim/atrim filters. This makes -t sample-accurate for audio and will allow further simplication in the future. Most of the FATE changes are due to audio now being sample accurate. In some cases a video frame was incorrectly passed with the old code, while its was over the limit.	12 years ago
Anton Khirnov	bee2d75b66	avconv: update to the new options syntax. The separators were changed from ',' to '\|' in all the filters.	12 years ago
Anton Khirnov	38f0c0781a	lavfi: merge avfiltergraph.h into avfilter.h We do not support using filters without AVFilterGraph in practice anyway, so there is no point in pretending we do.	12 years ago
Martin Storsjö	e760e1d408	avconv: Make sure the encoder exists before inspecting supported_list This fixes crashes when there is no encoder for the default codec of selected format. Signed-off-by: Martin Storsjö <martin@martin.st>	12 years ago
