* lavfi: rewrite nullsrc using the code in vsrc_testsrc.cStefano Sabatini2011-10-24
| | | | | | | | | Factorize code, extend the functionality of the filter, and make it return empty buffers. This is useful for filters which ignore the input frames content. This is also changing the syntax of the nullsrc source, and dropping the framerate expression evaluation, which does not look particularly useful.

* | vf_drawtext: make x and y options parametricStefano Sabatini2011-09-24
| | | | | | | | Address trac issue #378.
* | vf_drawtext: drop text wrapping featureStefano Sabatini2011-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Or in other word, do not go to the next line when the text cannot be rendered within the frame. The rationale is that wrapping is hard to manage, as it depends on the position of the text, thus making hard/impossible to compute the size occupied by the rendered text, and makes the filter behavior unpredictible with moving text (implemented in a pending patch). Also the current wrapping code is very limited (for example it splits words in the middle), and correctly handling wrapping requires much more complexity (alignment, gravity, word parsing etc.), while drawtext is meant to be only a thin wrapper around libfreetype, so such advanced features don't belong here.
* | vf_drawtext: do not set limitations on fontsizeStefano Sabatini2011-09-23
| | | | | | | | | | | | It may be needed to use values greater than 72, and in general greater than an arbitrary big value. Let the user choose what's too big for her.

* | asrc_anullsrc: implement a request_frame callback for returning framesStefano Sabatini2011-09-18
| | | | | | | | | | This is mainly useful for filters (like the sox synth), which overwrite the content of the passed data.
* | asrc_anullsrc: extend syntax to make it accept a non positional list of ↵Stefano Sabatini2011-09-18
| | | | | | | | | | | | | | | | | | arguments The new syntax is more extensible and more user-friendly. This breaks the previous syntax, should not be an issue as possibly no-one is already using anullsrc.
* | lavfi: add audio convert filterStefano Sabatini2011-09-16
| | | | | | | | | | | | | | | | | | | | | | Add aconvert filter to perform sample format, channel layout, and packing format conversion. The aconvert code depends on audio conversion code in libavcodec, so this requires a dependency on libavcodec. Based on previous work by S.N. Hemanth Meenakshisundaram and Mina Nagy Zaki, performed for the GSoC 2010 and 2011.
* | lavfi: add avfilter_all_channel_layouts public symbolStefano Sabatini2011-09-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This list is mainly useful to be directly used as a parameter by the audio sink buffer, when there is no need to force a specific channel layout. The list of formats is generated programmatically, and avoids channel layouts not supported by libavfilter (with more than 8 channels). We preferred to avoid compile-time generation in order to avoid some unnecessary complexity (build hacks, generating code maintainance etc.). A more compact way to express this list through the use of macros should be possible when libavfilter will support more than 8 channels, as there will be no need to filter out channel layouts with more than 8 channels. See thread: Subject: [FFmpeg-devel] [PATCH] lavfi: add ff_all_channel_layouts internal symbol Date: Sat, 20 Aug 2011 15:33:16 +0200
* | lavfi: rename avfilter_all_* function names to avfilter_make_all_*Stefano Sabatini2011-09-16
| | | | | | | | | | | | | | | | | | | | A function name should tell what the function does rather than what the function returns. This also avoids possible conflicts (e.g. between a function and a public list of all supported formats), and clarifies the code. Breaks audio API/ABI, add a backward compatibility layer for video API/ABI.
* | lavfi: bump minor and update APIchanges after recent updatesStefano Sabatini2011-09-12
| | | | | | | | | | | | | | | | | | These changes were forgotten in commits: lavfi: simplify signature for avfilter_get_audio_buffer() and friends (commit 2c0317419bc8c7f28496d5181d951bbe8837071f) and lavfi: consistently use int for sample_rate in AVFilterLink and AVFilterBufferRefAudioProps (commit 4381bddc9f93da34a44e683bdc4c05c6f061244e)
* | lavfi: consistently use int for sample_rate in AVFilterLink and ↵Stefano Sabatini2011-09-12
| | | | | | | | | | | | | | | | | | AVFilterBufferRefAudioProps Also consistent with AVCodecContext.sample_rate. Simplify/avoid pointless type checks and conversions. Breaks audio API/ABI.
* | lavfi: simplify signature for avfilter_get_audio_buffer() and friendsStefano Sabatini2011-09-12
| | | | | | | | | | | | | | | | | | | | | | The additional parameters were never used and are complicating the function interface. Also, they were inconsistent with the way the video API works. So this assumes that a requested samples buffer will have *always* the format specified in the requested link. This breaks audio filtering API and ABI.
* | lavfi: rename vsink_buffer.c to sink_buffer.c, and vsink_buffer.h to ↵Stefano Sabatini2011-09-06
| | | | | | | | | | | | | | | | buffersink.h This is done in order to clarify the non-video-specific nature of the buffersink code, as the result of the video/audio API unification of the previous commit, and for improving overall consistency.
* | lavfi: unify asink_buffer and vsink_buffer APIStefano Sabatini2011-09-06
| | | | | | | | | | | | | | | | | | The new API is more generic (no distinction between audio/video for pulling frames), and avoids code duplication. A backward compatibility layer is kept for avoiding tools ABI breaks (only for the video binary interface, audio interface was never used in the tools).
