* avcodec/packet_internal: Add proper PacketList structAndreas Rheinhardt2022-01-04
| | | | | | | | | | | | | | | Up until now, we had a PacketList structure which is actually a PacketListEntry; a proper PacketList did not exist and all the related functions just passed pointers to pointers to the head and tail elements around. All these pointers were actually consecutive elements of their containing structs, i.e. the users already treated them as if they were a struct. So add a proper PacketList struct and rename the current PacketList to PacketListEntry; also make the functions use this structure instead of the pair of pointers.

* packet: initialize time_base field to (0, 1) instead of (0, 0)Lynne2021-08-02

| | | | | This commit adds a long-requested by API users opaque fields for AVPacket, as well as a time_base field.
* avcodec: Pass HDR10+ metadata to packet side data in VP9 encoderMohammad Izadi2021-06-24
| | | | | | | | | | | | | HDR10+ metadata is stored in the bit stream for HEVC. The story is different for VP9 and cannot store the metadata in the bit stream. HDR10+ should be passed to packet side data an stored in the container (mkv) for VP9. This CL is taking HDR10+ from AVFrame side data in libvpxenc and is passing it to the AVPacket side data.

* avcodec/avpacket: use av_malloc() to allocate an AVPacketJames Almer2021-05-08
| | | | | | | | av_mallocz() is superfluous as get_packet_defaults() is called immediately after it's allocated, which will initialize the entire struct to default values. Signed-off-by: James Almer <jamrial@gmail.com>

* avcodec/avpacket: Don't write into non-writable bufferAndreas Rheinhardt2020-04-30
| | | | | | | | | | The data of an AVPacket may be a part of the data of an AVBufferRef; Therefore av_grow_packet() doesn't reallocate if the available space in the actual buffer is sufficient for the enlargement. But given that it also zeroes the padding it also needs to make sure that the buffer is actually writable; this commit implements this.

* libavcodec/avpacket: Don't simply forward return value of av_dict_set()Andreas Rheinhardt2020-04-23
| | | | | | | | | | | The documentation of av_dict_set() states that values >= 0 indicate success, whereas av_packet_unpack_dictionary() implies that return values > 0 are impossible. So only forward the return value of av_dict_set() in av_packet_unpack_dictionary() on error. (Btw: av_dict_set() does currently not return values > 0.)

* avcodec/avcodec, avpacket: Return blank packet on av_packet_ref() failureAndreas Rheinhardt2020-03-28
| | | | | | | | | | | | Up until now, it was completely unspecified what the content of the destination packet dst was on error. Depending upon where the error happened calling av_packet_unref() on dst might be dangerous. This commit changes this by making sure that dst is blank on error, so unreferencing it again is safe (and still pointless). This behaviour is documented. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/avpacket: Always treat dst in av_packet_ref as uninitializedAndreas Rheinhardt2020-03-28
| | | | | | | | | | | | | | | | | | av_packet_ref() mostly treated the destination packet dst as uninitialized, i.e. the destination fields were simply overwritten. But if the source packet was not reference-counted, dst->buf was treated as if it pointed to an already allocated buffer (if != NULL) to be reallocated to the desired size. The documentation did not explicitly state whether the dst will be treated as uninitialized, but it stated that if the source packet is not refcounted, a new buffer in dst will be allocated. This and the fact that the side-data as well as the codepath taken in case src is refcounted always treated the packet as uninitialized means that dst should always be treated as uninitialized for the sake of consistency. And this behaviour has been explicitly documented. Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>

* avpacket: reset dst side_data fields in av_packet_copy_propsYusuke Nakamura2018-02-14
