3fb49b6053 avauddec: Finish frames if they are header buffers only and don't produce any output 
Otherwise we will consider them as one frame of raw audio that is still
pending, and shift all timestamps by the amount of time spent with header
buffers.

00ebf95e08 avauddec: If decoding a frame failed, skip it 
Otherwise the next successfully decoded frame will get its timestamp and we
will slowly let a/v sync drift apart.

9e00a37d0e Don't use exported but undeclared core debug category symbols 
It's not right and won't work on Windows with MSVC.

Use g_strdelimit(), make sure to include comma as well, which
isn't included in G_STR_DELIMITERS.

2b387ba827 avauddec: use template caps intersection for accept-caps 
Avoid doing downstream caps queries when accept-caps should just
do a shallow caps check on the element itself

channels field.

7afaf5c020 avauddec: Access field using accessors 
Those fields are documented to only be safe to access using
accessors as their position is not part of the ABI.

30a4a28793 avauddec: Ensure input buffers have FF_INPUT_BUFFER_PADDING_SIZE padding, which is required by avcodec_decode_audio4 () 2015-06-30 19:19:42 +02:00

2a445cb5f2 avauddec: Remove custom buffer allocation function 
libav always uses planar audio formats nowadays, not much use in
us trying to allocate anything here until we add support for planar
aka non-interleaved audio formats at least in audioconvert.

c6cc7b385a avauddev: Unref decoded AVFrame after we're done with it

avdec_ac3.

24780708be avauddec: drain samples until libav doesn't have more data 
We use have_data (that comes from libav), instead of only trying 10
times, to know if there are more samples available. The old code was
machine dependent as different amount of samples could be decoded by
different type of (more powerful) machines, and 10 times was not always
sufficient.

ca1b5d8576 gst-libav: fix context leaks 
A AVCodecContext needs cleaning up before being freed.
Go through all of the allocations/setups to ensure none of them
can leak a context or its contents.

9febec71c0 avauddec: Don't believe we're negotiated if negotiation failed 
It can happen that negotiation fails during get_buffer(), but then
we don't retry later and never return NOT_NEGOTIATED upstream...
and instead run into assertions.

6571196fb8 libav: avcodec_close() also resets fields like the AVCodec 
We need to reload the defaults for the codec after closing it,
otherwise we can't access codec information like the supported
sample rates and can crash.

76423a4ba7 avauddec: fix garbled audio decoding in some cases 
Calculate output buffer size based on the number of
samples, channels and bytes per sample. The buffer
size was calculated based on linesize, which may
be larger than what's required.

d69dda0391 avauddec: Use a GstBuffer instead of a GstAdapter for collecting the output buffers 
This might cause less memcpies as the GstMemories of the buffers
are just appended into a single buffer.

c445b614f9 avauddec: accumulate buffers from a single input to push it all at once 
The base audio decoder wants a 1:1 mapping for input and output
buffers, so this decoder must accumulate data in an adapter and push
it all at once after all input has been processed.
