Whenever we alloc something based on a user-supplied size, we should
really use g_try_new(), otherwise we can easily be made to abort by
passing a ridiculously large number to us for allocing. Fixes
problems with some fuzzed files.
Check the possibly 64-bit atom size more carefully before casting it
to an int and passing it to gst_pad_pull_range(), otherwise we might
end up pulling 0 bytes, getting an empty buffer as requested and
dereferencing not available data whilst thinking we actually asked
for and got 0x1000000000000 bytes. Similar fix for push mode operation
where neededbytes ends up being 0 bytes, which makes us assert. Fixes
crash with broken or fuzzed file (NB #122378).
Fix the caps to include the depth (instead of width twice) in the caps of
audio/x-raw-int.
Fix negotiation to not only copy the rate/channels of the first structure.
Don't call gst_avi_demux_src_convert() for each single index entry. Not
only do we already have the pointer to the stream context, we also know
the formats we want to convert from and to already, so we may just as
well use optimised conversion routines that bypass some of the checks
and lookups made in gst_avi_demux_src_convert().
Include the header from where we include all the system headers with the
socket stuff before we try to define EAI_ADDRFAMILY ourselves, otherwise
we define it ourselves and then get a compiler warning if a system header
defines it as well without guarding against it being defined already.
Don't leak buffers when resyncing to a keyframe.
Avoid leaking buffers when exiting the loop on error conditions.
Add some more debug info.
Fixes#585911
The previous patch to add support for additional sample formats possibly
introduced a reentrancy bug: a variable used for a loop index was declared
static. This patch fixes that, and also adds a "/* *INDENT-ON* */" annotation
following the macro block. (I don't know what the annotation is for, but the
adder, where I copied this from, has it).
Setting it to a value<16 would cause crashes before because
current_plane was set to the old number of planes-1. Also
fix calculations for non-2^n planes values.
The diff is a signed integer, not an unsigned one of course.
In modes other than GST_DEINTERLACE_ALL every frame has twice the
duration of the field duration.
When there are less timestamps that there are samples, fill up the sample table
with the last know timestamp. This situation can happen when the last sample
does not decode and doesn't need a timestamp. We however calculate the total
track length using the last sample timestamp so we need to have something
sensible in there.
Fixes#585056
in24 samples are normally big-endian but an enda box can change this to
little-endian. Recurse into the in24 box and find the enda box so that we get
the endianness right.
Fixes#582515
gst_adapter_take_buffer doesn't allow buffer to be empty.
Simply skip any part where the content is empty. Don't
create a pad for it either.

s/@GST_PLUGIN_LDFLAGS@/$(GST_PLUGIN_LDFLAGS)/
@-substitued variables variables are defined as make variables automagically,
and this gives the user the freedom to say make GST_PLUGIN_LDFLAGS=-myflag
For this add a "mode" property that defaults to "interlaced" for now as
most decoders/demuxers don't properly set the "interlaced" field on the
caps yet.
If this property is set to "auto" the element will work in passthrough
mode unless the caps contain the "interlaced" field.

Push tags already if only one pad was added, no need to wait for
the second one.
When generating our index set has_video and has_audio if we find
video or audio in case the FLV header has incorrect data.

It does not do seeking yet, it supports pull and push mode so
YES
you can use it to play youtube videos directly from an HTTP uri.
Not so much testing done yet but it parses metadata, reply to
duration queries, etc...
First of all a keyframe seek should be done to the
keyframe right before the requested position and not
to the keyframe that is nearest to the requested position.
Use per track index arrays and use our new binary search function
from core to speed up the search.
Rewrite the quant table parsing to also handle multiple tables in one JPEG HDQ
segment.
Handle more jpeg types by keeping track of the tables used per component and
putting the used ones in the quant headers.
Read the timestamp of the incomming buffer before we push it in the adapter and
flush it out again as the buffer might be unreffed then and we read from invalid
memory.
Fixes#581444.
Don't require width/height on the caps. Use the SOF header to find width/height
and fall back to the caps if there is no SOF. Also use the SOF info to find the
subsampling and quantization tables used. This allows us to set the right type
value in the JPEG rtp header.
Deprecate the quality property, it's unused now and it was used wrongly before.
Always send full quant tables for now until we have some code to detect default
ones.
Fixes#580880
Use the width and the height from the payload headers and set them on the
output caps for added awesomeness.
Fix quant parsing, we need to check the type in the lower 6 bits.
Add first bits of caching quantization tables.
Server eof (e.g. connection closed) is announced as connection closed,
so better record state and act accordingly to prevent (read/write)
errors during subsequent teardown/cleanup sequences. #Fixes 580851.(c).
We didn't handle unsynchronization at all up to now, which might have
caused frames to not be extracted - esp. frames after an APIC picture
frame. Fixes#577468.
If the codec is actually something else (e.g. mjpeg) change the caps to
match when parsing the ESDS atom.
Also, for AAC, override rate and channels with correct values read from
ESDS, since the rate/channels values elsewhere are often wrong.
We implemented the AAL2 packing, add the encoding-name for those to the caps and
a property to force AAL2 decoding (always TRUE for now).
Implement RFC3551 unpacking for regular G726.
See #567140.
In streaming mode, avidemux is not supposed to send an EOS event downstream but
it is supposed to return UNEXPECTED from the chain function instead so that
upstream can do the right EOS handling.
Fix the duration query so that it also works with formats other than
TIME, such as DEFAULT to get the number of frames.
Add a convert function.
Fixes#578052.
In the sequence of header lengths, for headers >127 bytes, we use
multiple bytes to encode the length. Bytes other than the last must have
the top (flag) bit set.
The on-npt-stop signals was added only recently to rtpjitterbuffer in
-bad, so check if the signal exists before g_signal_connect()ing to
it, to avoid warnings.
Some clips (trailers) may have (length-wise) unbalanced streams,
which stalls the pipeline if seeking into that region.
Additional stream synchronization can handle this, as well as
sparse (subtitle) streams (at some later time ?)
Try to post a decent error message when it looks like we're failing
because the Real RTSP extension plugin is missing. Also add i18n
bits for rtspsrc so our error messages get translated.
Cater for DELTA_UNIT flag on buffers, keep track of current
position, remove and warn about edit lists if any (as those
as are de facto discarded anyway), add some debug statements
and indent fixes.
The audioMuxVersion structure is packed in such a way that the codec
data does not start byte-aligned, which means there's an extra bit of
padding at the end. We don't want that bit in the codec data, since
some decoders seem get confused when they're fed with an extra codec
data byte (also it's just not right of course).
Add network interface selection when joining multicast groups.
Useful when using the udpsrc on multihomed hosts.
Fixes#575234.
API: GstUDPSrc::multicast-iface
Non-ok flow returns may happen for a variety of perfectly legitimate and expected reasons
(temporarily not linked, seeking, pipeline shutdown), so we really shouldn't spew ERROR
debug messages to stderr in those cases. Fixes#570781. (Seems like someone already took
care of some of these.)
Standard pull mode loop based SEEK handling fails in push mode,
so convert the SEEK event appropriately and dispatch to upstream.
Also cater for NEWSEGMENT event handling, and properly inform
downstream and application of SEEKABLE capabilities, depending
on scheduling mode and upstream.
Previously the sockaddr length used for recvfrom() was calculated as
sizeof (struct sockaddr). However, this is too little to hold an IPv6
address, so the full size of the gst_sockaddr union should be used
instead.
MS RTSP spec states that the UDP port pair used in subsequent SETUP
requests for various streams must be identical (since there will actually
be only 1 stream of muxed asf packets). Following traditional specs and
using different port pairs in the SETUPs for separate streams will result
in all but the first one failing and only one stream being streamed.
So, in appropriate circumstances, retry UDP SETUP using previously used
port pair. Fixes#552650.
When we are dealing with connected sockets shared between a udpsrc and a udpsink
we might receive ICMP connection refused error messages in udpsrc that will
cause it to go into a bursty loop because the poll returns right away without a
message to read.
Instead of looping, read the error message from the error queue in udpsrc.
Fixes#567857.
Reading integers from random memory addresses will result
in SIGBUS on some architectures if the memory address
is not correctly aligned. This can happen at two
places in avidemux so we should use GST_READ_UINT32_LE
and friends here. Fixes bug #572256.
stps atoms contain "partial sync" information, which means that it's
a sync point where pts != dts. This is needed to properly handle
MPEG2, H.264, Dirac, etc., in quicktime.
Not all Matroska files have a Tags element which contains
information about the title among other things. Most video
Matroska files only contain the Title element so we
should parse this too. Fixes bug #570435.
Move reallocating the history buffer out of _compute_frequencies() and call the
right function as needed. Add some logging and tweak the formatting of existing
logging. Simplify setting need_new_coefficients when changing properties.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered. Fix warnings that gtk-doc points out.
Introduce a new max-delay property that can only
be set before going to PLAYING or PAUSED. This
is used to limit the maximum delay and is set
to the current delay by default.
Using this will make sure that we have enough data
in our internal ringbuffer for the echo. With dynamic
reallocation of the ringbuffer as used before silence
could've been used as the echo directly after setting
a new delay.
Link to properties. Correct titles for examples. Document a few trivial cases. Keep lists in section file and docs/plugins/Makefile.am alphabetically ordered.
Save some allocations if the echo delay is increased often
during playback by always allocating enough memory to hold
data up to the next complete second, i.e. in the worst case
allocate memory for one additional second.
Add a note to the docs that audioecho's reverb will
sound metallic. This happens because for a real
reverb filter additional filtering is necessary.
Also note which values should be used for the delay
property to get an echo effect.
The element can add an echo and a simple reverb effect to
an audio stream but for a real reverb filter it would need
some additional filtering to prevent a metallic-sounding
result.
