* avcodec/mlpenc: Set AV_PKT_FLAG_KEY manuallyAndreas Rheinhardt2021-09-281-0/+1
| | | | | | | | | | TrueHD/MLP is one of the audio formats with keyframes. Currently, the generic encoding code just sets the keyframe flag for all returned packets, yet this is wrong for these encoders and will be changed in a future commit. So set the flag here for those packets that ought to have it. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mlpenc: remove frame_size array from private contextPaul B Mahol2021-09-051-23/+7
| | | | | | | It is supposed to be used with different bit depth and/or sample rates per each substream, but such currently not implemented feature is not important and current state causes problems when implementing variable restart interval to fix decoding with sample rates not multiple of 40.

* avcodec/encode: Always use intermediate buffer in ff_alloc_packet2()Andreas Rheinhardt2021-06-081-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Up until now, ff_alloc_packet2() has a min_size parameter: It is supposed to be a lower bound on the final size of the packet to allocate. If it is not too far from the upper bound (namely, if it is at least half the upper bound), then ff_alloc_packet2() already allocates the final, already refcounted packet; if it is not, then the packet is not refcounted and its data only points to a buffer owned by the AVCodecContext (in this case, the packet will be made refcounted in encode_simple_internal() in libavcodec/encode.c). The goal of this was to avoid data copies and intermediate buffers if one has a precise lower bound. Yet those encoders for which precise lower bounds exist have recently been switched to ff_get_encode_buffer() (which automatically allocates final buffers), leaving only two encoders to actually set the min_size to something else than zero (namely aliaspixenc and hapenc). Both of these encoders use a very low lower bound that is not helpful in any nontrivial case. This commit therefore removes the min_size parameter as well as the codepath in ff_alloc_packet2() for the allocation of final buffers. Furthermore, the function has been renamed to ff_alloc_packet() and moved to encode.h alongside ff_get_encode_buffer(). Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@outlook.com>

* avcodec/mlpenc: Add const where appropriateAndreas Rheinhardt2021-05-021-10/+12
| | | | | | | | | | | | The MLP/TrueHD encoder uses pointers to non-const to access several static objects that are only initialized at runtime and are therefore not declared as const. This does not result in compiler warnings, but it is fragile, as these objects are really not to be modified as they are not owned by any encoder instance. Therefore this commit adds const to the pointed to type of the pointers used to access them after their initialization. One object has even been made const.

* avcodec: Constify AVCodecsAndreas Rheinhardt2021-04-271-2/+2
| | | | | | | | | | Given that the AVCodec.next pointer has now been removed, most of the AVCodecs are not modified at all any more and can therefore be made const (as this patch does); the only exceptions are the very few codecs for external libraries that have a init_static_data callback.

* avcodec/mlpenc: Simplify finding best codebookAndreas Rheinhardt2020-12-311-24/+10
| | | | | | | | | | | | Finding the best codebook involves comparing different paths, where each path is a sequence of several decisions (namely which codebook to use). Up until now, these sequence was encoded in a NUL-terminated string and the actual decisions were encoded as ’\0'..'\3' (which encoded 0..3). This commit modifies this to actually encode it via 0..3 by switching away from a C-string to a simple array with an explicit length field.

* avcodec/mlpenc: Fix memleak upon init failureAndreas Rheinhardt2020-09-151-0/+2
| | | | | | | | | If an error happens during init after an allocation has succeeded, the already allocated data leaked up until now. Fix this by setting the FF_CODEC_CAP_INIT_CLEANUP flag. Reviewed-by: Paul B Mahol <onemda@gmail.com> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avcodec/mlpenc: remove delay codec capabilityJames Almer2020-07-011-5/+2
| | | | | | | | | | The encoder has no delayed packets at the end of the encoding process, so signaling this capability is unnecessary. This also fixes an assertion failure introduced in 827d6fe73d, as return values higher than 0 are not expected. Signed-off-by: James Almer <jamrial@gmail.com>

* mlpenc: Working MLP/TrueHD encoderJai Luthra2016-09-171-0/+2416
* Multichannel support for TrueHD is experimental There should be downmix substreams present for 2+ channel bitstreams, but ffmpeg decoder doesn't need it. Will add support for this soon. * There might be lossless check failures on LFE channels * 32-bit sample support has been removed for now, will add it later While testing, some samples gave lossless check failures when enforcing s32. Probably this will also get solved with the LFE issues. Signed-off-by: Jai Luthra <me@jailuthra.in>
