Anton Khirnov	b420a27e74	avconv: allow -b to be used with streamcopy In this mode it tells the muxer about the bitrate of the input stream.	8 years ago
Diego Biurrun	122de16dd8	Replace cmdutils_common_opts.h by a macro	8 years ago
Diego Biurrun	01348e411f	avconv_opt: Consistently iterate through hwaccels array in all cases avconv_opt.c:188:19: warning: comparison of unsigned expression < 0 is always false [-Wtype-limits]	8 years ago
Diego Biurrun	943533d64c	avconv: Correct function pointer assignments in options array Fixes several warnings of the type avconv_opt.c:2356:5: warning: ISO C forbids initialization between function pointer and ‘void *’ [-Wpedantic]	8 years ago
James Almer	064f19f39e	avconv: support parsing bitstream filter options Example usage: avconv -i INPUT -bsf filter[=opt1=val1:opt2=val2] OUTPUT Signed-off-by: James Almer <jamrial@gmail.com> Signed-off-by: Anton Khirnov <anton@khirnov.net>	8 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	398f015f07	avconv: buffer the packets written while the muxer is not initialized	9 years ago
Anton Khirnov	5fa255b65c	avconv: initialize output framerate earlier This will be needed in the following commits.	9 years ago
Anton Khirnov	90944ee3ab	avconv: refactor selecting an encoder Fail immediately if automatic encoder selection failed. Always set the stream_copy/encoding_needed flags in one place.	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	fe7b21c8f1	avconv: fix parsing bitstream filters The current code modifies the user-supplied string, which is shared for the whole output file. So a bitstream filter specification applied to multiple streams would not work correctly.	9 years ago
Anton Khirnov	80fb19bc23	avconv: fix a check for av_bsf_get_by_name() return value	9 years ago
Vittorio Giovara	41ed7ab45f	cosmetics: Fix spelling mistakes Signed-off-by: Diego Biurrun <diego@biurrun.de>	9 years ago

Anton Khirnov	4426540f0c	avconv: switch to the new BSF API	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	fb472e1a11	avconv: add support for Intel QSV-accelerated transcoding Signed-off-by: Luca Barbato <lu_zero@gentoo.org>	9 years ago

Vittorio Giovara	b5e4f393b6	avconv: Make the private options discovery more manifest	9 years ago
Vittorio Giovara	3973f0f773	Revert "avconv_opt: Allow printing private options" This reverts commit `7bb1c1bfd2`. A long existing version in the form of avconv -h decoder=h264 already existed, and this just duplicates it.	9 years ago
Vittorio Giovara	7bb1c1bfd2	avconv_opt: Allow printing private options Add an allowed parameter to -h and --help avconv option to print private options from a codec, format, or filter, named with the provided input value. In case multiple classes are found (eg. mov demuxer and mov muxer, or h264 decoder and h264 demuxer) print all options from all classes. It is possible to select the type of class to print by adding it before the name (eg. demuxer:mov and muxer:mov, or decoder:h264and demuxer:h264).

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.	10 years ago
Anton Khirnov	be101bc1e3	avconv: create the complex filtergraphs earlier Since global options are processed before all the other options now, we do not have to try creating the complex filtergraphs several times anymore, it is enough to do it once after the input files are opened.	10 years ago
Anton Khirnov	1959351aec	avconv: move the no streams failure to open_output_file() It is a better place for it, there is no reason to wait until transcode_init().	10 years ago
Anton Khirnov	bd2ab27c48	avconv: use read_file() for reading the 2pass stats Also, drop the now unused cmdutils_read_file(). There is no reason to have two functions doing essentially the same thing.	10 years ago
Anton Khirnov	6d5d924604	avconv: move handling the 2pass logfile into avconv_opt It more logically belongs there.	10 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.
