Justin Ruggles 06deaf8ad3 idcin: return 0 from idcin_read_packet() on success. 
This matches the AVInputFormat.read_packet() API.
 2013-01-09 14:49:07 -05:00
Justin Ruggles 5d0450461f idcin: better error handling 
Add some additional checks for EOF and print error messages on an incomplete
header or packet.

FATE reference updated for id-cin-video due to the demuxer no longer
returning a partial video packet at EOF.
 2013-01-09 14:49:07 -05:00
Justin Ruggles 33f58c3616 idcin: check for integer overflow when calling av_get_packet() 
chunk_size is unsigned 32-bit, but av_get_packet() takes a signed int as the
packet size.
 2013-01-09 14:49:06 -05:00
Justin Ruggles 7040e479a1 idcin: allow seeking back to the first packet 
Also, do not allow seek-by-byte, as there is no way to find the next packet
boundary.
 2013-01-09 14:49:06 -05:00
Justin Ruggles 49543373f3 idcin: set AV_PKT_FLAG_KEY for video packets with a palette 2013-01-09 14:49:06 -05:00
Justin Ruggles ccc0ffb1ba idcin: set start_time and packet duration instead of manually tracking pts. 
Also, use 1 / sample_rate for audio stream time_base.
 2013-01-09 14:49:06 -05:00
Justin Ruggles 4b840930da idcin: set channel_layout 2013-01-09 14:49:06 -05:00
Justin Ruggles 12c2530b1d idcin: fix check for presence of an audio stream 2013-01-09 14:49:06 -05:00
Justin Ruggles b0c96e0613 idcin: validate header parameters 
Avoids using unsupported parameters and signed integer overflows.
 2013-01-09 14:49:06 -05:00
Justin Ruggles f7bf72a4a1 idcinvideo: correctly set AVFrame defaults 2013-01-09 14:49:06 -05:00

Justin Ruggles af68a2baae au: use %u when printing id and channels since they are unsigned 2013-01-09 11:52:57 -05:00
Justin Ruggles 47d029a4c1 au: validate sample rate 2013-01-09 11:52:57 -05:00
Justin Ruggles c837b38dd3 au: move skipping of unused data to before parameter validation 
Also do not unnecessarily skip 0 bytes.
 2013-01-09 11:52:57 -05:00
Justin Ruggles fb48f825e3 au: do not arbitrarily limit channel count 
Nothing in the AU specification sets a limit on channel count.
We only need to avoid an overflow in the packet size calculation.
 2013-01-09 11:52:57 -05:00
Justin Ruggles 2613de8805 au: do not set pkt->size directly 
It is already set by av_get_packet() even for partial reads.
 2013-01-09 11:52:57 -05:00
Justin Ruggles bd4cdef5a8 au: set block_align and use it in au_read_packet() 2013-01-09 11:52:56 -05:00
Justin Ruggles 9a7b56883d au: set bit rate 2013-01-09 11:52:56 -05:00
Justin Ruggles 3f98848d6e au: validate bits-per-sample separately from codec tag 2013-01-09 11:52:56 -05:00
Justin Ruggles 59220d559b oggenc: add a page_duration option and deprecate the pagesize option 
This uses page duration instead of byte size to determine when to buffer
the page. Also, it tries to avoid continued pages by buffering the current
page if there are already packets in the page and adding the next packet
would require it to be continued on a new page. This can improve seeking
performance.

The default page duration is 1 second, which is much saner than filling
all page segments by default.

Justin Ruggles 4164b0e8d3 lavr: mix: reduce the mixing matrix when possible 
If the matrix results in an output channel not getting a contribution
from any input channel and the corresponding input channel does not
contribute to any outputs, we can skip the channel during mixing and
silence it after mixing.

If the matrix results in an input channel not contributing to any output
channels and it is not in the output mix, or if the input channel only
contributes fully to the same output channel, we can skip the channel
during mixing.

If the matrix results in an output channel only getting full
contribution from the corresponding input channel and that input channel
does not contribute to any other output channels, we can skip the
channel during mixing.

Justin Ruggles 074a00d192 lavr: add a public function for setting a custom channel map 
This allows reordering, duplication, and silencing of input channels.
 2013-01-07 21:49:06 -05:00
Justin Ruggles 4d68269d58 lavr: typedef internal structs in internal.h 
Simplifies header dependencies by not including all other internal headers
in internal.h.
 2013-01-07 21:49:05 -05:00
Justin Ruggles 95d01c3f1c x86: lavr: use the x86inc.asm automatic stack alignment in mixing functions

Justin Ruggles d02202e08a opt: avoid segfault in av_opt_next() if the class does not have an option list 
CC: libav-stable@libav.org
 2012-12-22 15:43:27 -05:00
Justin Ruggles 5778299c7e ttadec: fix last frame handling when seeking 
Using a frame count, as is done currently, does not work at all with
seeking. Instead, when the number of samples in the final frame has
been decoded, we check if only the 32-bit CRC is remaining. If so, we
assume that it is the final frame.

There is no longer a need to keep total_frames in TTAContext.
 2012-12-22 14:45:35 -05:00
Justin Ruggles 68a04b0cce alacdec: do not be too strict about the extradata size 
Sometimes the extradata has duplicate atoms, but that shouldn't prevent
decoding. Just ensure that it is at least 36 bytes as a sanity check.

Justin Ruggles aef5150719 flac: only set channel layout if not previously set or on channel count change 
Fixes Bug 402

Justin Ruggles b2fe6756e3 lavr: add option for dithering during sample format conversion to s16 2012-12-19 18:52:54 -05:00
Justin Ruggles f1c2915ce1 lavr: remove automatic context close/open for resampling compensation 
It adds unnecessary complication for insignificant usability improvement.
The user really should know if they'll need resampling compensation before
opening the context.

Note that only the documentation has changed. The current functionality will
still work until the next major bump.

Justin Ruggles b35e5d985d doc: improve documentation for the asyncts filter first_pts option 
Note the time base for the option. Add an additional example description.
 2012-12-13 13:02:21 -05:00
Justin Ruggles c143de40c3 asyncts: fix the asyncts behavior when using the first_pts option 
Currently it will do padding, but it does not properly handle
start-of-stream trimming as documented.
 2012-12-13 13:02:21 -05:00
Justin Ruggles 8083332c2d asyncts: use clipped delta value when setting resample compensation 
The max_comp option is supposed to limit maximum compensation, but
currently the clipped value is not actually used.

Justin Ruggles 14758e3211 lavr: temporarily store custom matrix in AVAudioResampleContext 
This allows AudioMix to be treated the same way as other conversion contexts
and removes the requirement to allocate it at the same time as the
AVAudioResampleContext.

The current matrix get/set functions are split between the public interface
and AudioMix private functions.

Justin Ruggles e70c5b034c swfdec: do better validation of tag length 
Avoids trying to read a packet with 0 or negative size.
Avoids a potential infinite loop due to seeking backwards.

Partially based on a patch by Michael Niedermayer.

Justin Ruggles ab87d9b667 nuv: check for malloc failure when allocating extradata 
Also make sure extradata is freed in the case where multiple
NUV_EXTRADATA frame types are found. This may not happen in practice,
but it could happen in a malformed stream, which would lead to a memleak
if not handled.

Justin Ruggles 1d86aa8b0f lavr: do not pass consumed samples as a parameter to ff_audio_resample()
