Nicolas George	9c1d649ce5	overlay: clear cur_buf on main input link. A reference is kept in the queue and freed after use.	13 years ago
Steven Robertson	82ecae8a70	lavfi: add alphaextract and alphamerge filters These filters are designed for storing and transmitting video sequences with alpha using higher-efficiency codecs such as x264 which don't natively support an alpha channel. 'alphaextract' takes an input stream with an alpha channel and returns a video containing just the alpha component as a grayscale value; 'alphamerge' takes an RGB or YUV stream and adds an alpha channel recovered from a second grayscale stream.

Anton Khirnov	4c9080a7ef	lavfi: unref AVFilterLink.out_buf in ff_end_frame(). This reduces code duplication and prevents stale pointers from remaining on the link.	13 years ago
Anton Khirnov	07bad27810	lavfi: unref AVFilterLink.cur_buf in ff_end_frame(). This reduces code duplication and prevents stale pointers from remaining on the link.	13 years ago
Anton Khirnov	533fd5b5b4	vsrc_testsrc: avoid an unnecessary avfilter_ref_buffer().	13 years ago
Anton Khirnov	5b50ae94e6	vf_slicify: clear AVFilterLink.cur_buf in start_frame(). The buffer is passed on to the next filter, so we shouldn't keep any pointers to it.	13 years ago
Anton Khirnov	0393af4f0b	vf_settb: simplify start_frame(). Avoid pointless filter ref/unref. Just use the reference passed to start_frame().	13 years ago
Anton Khirnov	9203fa0b32	vf_fieldorder: don't give up its own reference to the output buffer.	13 years ago
Anton Khirnov	f493c644cd	vf_pad: don't give up its own reference to the output buffer.	13 years ago
Anton Khirnov	ad8b6326aa	vf_overlay: don't access a buffer reference that's been given away.	13 years ago
Anton Khirnov	7155763b78	vf_drawtext: don't give up its own reference to the input buffer. Directly forwarding the input buffer to the next filter means that drawtext no longer owns any references to it and thus shouldn't refer to it in any way.	13 years ago

Stefano Sabatini	712d82130e	lavfi/avfiltergraph: apply misc fixes to fix avfilter_graph_request_oldest() @return doxy	13 years ago
Nicolas George	d483867525	avfiltergraph: document a catch in request_oldest(). This one is tricky. Consider a graph with two sink links, A and B. request_oldest() requests on A, and A returns EOF. This EOF causes a filter to flush pending frames to B; they are unrequested. Then request_oldest() moves on to B, and B returns EOF.	13 years ago
Nicolas George	f98d814bb6	avfiltergraph: add a debug message on EOF.	13 years ago
Nicolas George	d06bfda07e	lavfi: rescale link->current_pts. The doxy says, and the heap implementations assumes, it is in AV_TIME_BASE units.	13 years ago
Stefano Sabatini	fda968aa8f	lavfi: decrease logging level of message showing initial parameters Reduce log clutter, consistent with `1a49a169eb`.	13 years ago
Steven Robertson	c88d98fe4a	lavfi/movie: reindent after the previous patch Signed-off-by: Steven Robertson <steven@strobe.cc> Signed-off-by: Stefano Sabatini <stefasab@gmail.com>	13 years ago
Steven Robertson	ac726a4f0c	lavfi/movie: flush decoder frames on EOF movie currently forwards EOF (or begins looping) immediately upon reaching the last packet in the input stream, which can leave frames in the decoder. This change first tries to read any remaining packets from the decoder before forwarding EOF.

Stefano Sabatini	a5382b50f2	lavfi/buffersink: restore possibility to pass opaque data Use the init_opaque callback for the purpose. Fix regression introduced in `a5e8c41c28`. In particular, fix lavfi device in case a conversion to the supported (packed) formats is needed.	13 years ago
Stefano Sabatini	21d5609826	lavfi: add init_opaque callback This will be used by filters which require an opaque field to be passed in input. Should be required only for filters which imply a programmatic use. This is possibly a temporary solution, to be removed when we'll have a clearer and better agreememnt of how/if to pass binary data for initializing a filter. See thread: Subject: [FFmpeg-devel][PATCH] lavfi: add init2 callback Date: Fri, 6 Jul 2012 01:22:17 +0200	13 years ago
Anton Khirnov	cd99146253	lavfi: add error handling to filter_samples().	13 years ago
Anton Khirnov	083d0f6be8	asplit: don't leak the input buffer.	13 years ago
Anton Khirnov	1ffb645662	af_resample: fix request_frame() behavior. Make sure that an output frame has really been produced before returning 0.	13 years ago
