Anton Khirnov e9b992d035 lavfi: add error handling to draw_slice(). 2012-07-22 09:14:05 +02:00
Anton Khirnov ebc8d97481 lavfi: add error handling to start_frame(). 2012-07-22 09:14:04 +02:00
Ronald S. Bultje 731fa116b4 yadif: use emms_c() instead of inline assembly for emms invocations. 2012-07-21 17:16:49 -07:00
Ronald S. Bultje 3db407038e lavfi: use const for AVFilterPad declarations in all filters. 2012-07-21 16:31:15 -07:00
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.

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.

Anton Khirnov 533fd5b5b4 vsrc_testsrc: avoid an unnecessary avfilter_ref_buffer(). 2012-07-20 21:09:57 +02:00
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.
 2012-07-20 21:09:48 +02:00
Anton Khirnov 0393af4f0b vf_settb: simplify start_frame(). 
Avoid pointless filter ref/unref. Just use the reference passed to
start_frame().
 2012-07-20 21:08:50 +02:00
Anton Khirnov 9203fa0b32 vf_fieldorder: don't give up its own reference to the output buffer. 2012-07-20 21:08:26 +02:00
Anton Khirnov f493c644cd vf_pad: don't give up its own reference to the output buffer. 2012-07-20 21:08:13 +02:00
Anton Khirnov ad8b6326aa vf_overlay: don't access a buffer reference that's been given away. 2012-07-20 21:07:51 +02:00
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.

Anton Khirnov d19499c796 vf_gradfun: don't store two pointers to one AVFilterBufferRef. 2012-07-20 21:07:11 +02:00
Anton Khirnov 0fe010a36f vf_delogo: don't store two pointers to one AVFilterBufferRef. 2012-07-20 21:06:49 +02:00
Anton Khirnov 51a8049be8 vf_aspect: 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.

Anton Khirnov cd99146253 lavfi: add error handling to filter_samples(). 2012-07-09 08:25:19 +02:00

Anton Khirnov 1ffb645662 af_resample: fix request_frame() behavior. 
Make sure that an output frame has really been produced before returning
0.

Anton Khirnov 6f834293d3 af_asyncts: fix request_frame() behavior.

Justin Ruggles 8ca08066fc lavr: Use AV_SAMPLE_FMT_NONE to auto-select the internal sample format 
Also make this the default value.
 2012-07-08 15:22:11 -04:00
Anton Khirnov b7558ac293 af_amix: avoid spurious EAGAIN. 
Input on/off state can change in request_samples(), which can result in
a state where only the first input is active. get_available_samples()
will then return 0, and request_frame() will fail with EAGAIN even
though there is data on the single active input.

Take this into account and check the number of active inputs again after
calling request_samples().
 2012-07-06 13:51:58 +02:00
Anton Khirnov 54bf88e65f af_amix: return AVERROR(EAGAIN) when request_frame didn't produce output. 
0 should only be returned when there was at least one output frame.
 2012-07-06 13:51:58 +02:00
Anton Khirnov 428b369804 af_amix: only consider negative return codes as errors. 2012-07-06 13:51:58 +02:00
Mans Rullgard 7c29377b70 lavfi: reclassify showfiltfmts as a TESTPROG 
This tool uses lavfi internal symbols not accessible in shared
libraries.  TESTPROGS are linked statically to allow them use of
library internals not normally exported.

Anton Khirnov a5e8c41c28 lavfi: remove 'opaque' parameter from AVFilter.init() 
It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.
