pfeatherstone	decdef12f5	[FFmpeg] decoding and demuxing improvements (#2784) ... * typo * - added compile time information to audio object. Not convinced this is needed actually. I'm perfectly happy just using the ffmpeg::frame object. I'm pretty sure I'm the only user who cares about audio. - created resizing_args and resampling_args * smaller videos for unit tests * shorter videos for unit tests * - decoder and demuxer: you now resize or resample at the time of read. therefore you don't set resizing or resampling parameters in constructor, but you pass them to read() - added templated read() function - simplified load_frame() * inherit from resizing_args and resampling_args * reorganised the tests to segragate decoding, demuxing, encoding and muxing as much as possible * much more basic example * demxing examples split * examples * fixing examples * wip * Fix load_frame() * added frame - specific tests * - makes sense to have a set_params() method rather than constructing a new object and moving. I mean, it works and it absolutely does the right thing, and in fact the same thing as calling set_params() now, but it can look a bit weird. * notes on defaults and good pairings * Update ffmpeg_demuxer.h Watch out for `DLIB_ASSERT` statements. Maybe one of the unit tests should build with asserts enabled. * Update ffmpeg_details.h * Update ffmpeg_muxer.h * WIP * WIP * - simplified details::resizer - added frame::set_params() - added frame::clear() - forward packet directly into correct queue * pick best codec if not specified * added image data * warn when we're choosing an appropriate codec * test load_frame() * - for some reason, you sometimes get warning messages about too many b-frames. Resetting pict_type suppresses this. - you can move freshly decoded frames directly out. * callback passed to push() * I think it's prettier this way * WIP * full callback API for decoder * updated tests * updated example * check the template parameter is callable and has 1 argument first before getting it's first argument * Potential bug fix * - write out the enable_if's explictly. It's fine. I think it's clear what's going on if someone cares - guard push() with a boolean which asserts when recursion is detected * pre-conditions on callbacks: no recursion --------- Co-authored-by: pf <pf@me> Co-authored-by: Your name <you@example.com>	1 year ago
