* avformat/librist: increase default loglevelMarton Balint2021-03-132-6/+7
| | | | | | | | | Also remove AV_LOG_SIMULATE from the list as it is not used directly, and do not use panic level on unknown loglevel, but make them warn. Also fix mapping of NOTICE/INFO/VERBOSE and add documentation about when the option should actually be used. Signed-off-by: Marton Balint <cus@passwd.hu>

| | | | | | | | Maximum packet size is 10000 (RIST_MAX_PACKET_SIZE, which is unfortunately private) minus the RIST protocol overhead which is 28 bytes for the unencrypted case, 36 for the encrypted case. Signed-off-by: Marton Balint <cus@passwd.hu>

* avdevice/pulse_audio_dec: do not read undersized framesMarton Balint2021-03-121-30/+41
| | | | | | | | | | | Keep on reading fragments until we got fragment_size amount of data, otherwise we might get frames with 1-2 samples only if pa_stream_peek is called slightly less frequently than sample rate. Note that fragments might contain a lot less data than fragment_size, so reading multiple fragments to get fragment_size amount of data is intentional. Signed-off-by: Marton Balint <cus@passwd.hu>

* avcodec: add a get_encode_buffer() callback to AVCodecContextJames Almer2021-03-127-4/+131
| | | | | | | | | | | This callback is functionally the same as get_buffer2() is for decoders, and implements for the new encode API the functionality of the old encode API had where the user could provide their own buffers.

* cbs_sei: Detect payload overflows when reading SEI messagesMark Thompson2021-03-121-1/+16
| | | | | | | | | | The top-level GetBitContext is sized for the whole NAL unit, so it fails to detect overflows where a payload continues into the following message. To fix that, we make a new context on the stack for reading each payload.

* cbs_h265: Detect more reference combinations which would overflow the DPBMark Thompson2021-03-121-2/+21
| | | | | | | | | | | | | | | | | | | | | In total, the number of short term references (from the selected short term ref pic set), the number of long term references (combining both the used candidates from the SPS and those defined in the slice header) and the number of instances of the current picture (usually one, but can be two if current picture reference is enabled) must never exceed the size of the DPB. This is a generalisation of the condition associated with num_long_term_pics in 7.4.7.1. We use this to apply tighter bounds to the number of long term pictures referred to in the slice header, and also to detect the invalid case where the second reference to the current picture would not fit in the DPB (this case can't be detected earlier because an STRPS with 15 pictures can still be valid in the same stream when used with a different PPS which does not require two DPB slots for the current picture).

* avcodec/cbs_sei: Fix leak of AVBufferRef on errorAndreas Rheinhardt2021-03-121-8/+8
| | | | | | | | | | | | | | | An AVBufferRef (and the corresponding AVBuffer and the underlying actual buffer) would leak in ff_cbs_sei_add_message() on error in case an error happened after its creation and before it has been attached to more permanent storage. Fix this by only creating the AVBufferRef immediately before attaching it to its intended target position. (Given that no SEI message currently created is refcounted, the above can't happen at the moment. But Coverity already nevertheless noticed: This commit fixes Coverity issue #1473521.)

* avcodec/cbs: Remove redundant checks for CodedBitstreamContext.codecAndreas Rheinhardt2021-03-121-3/+3
| | | | | | | | | | | | | Setting this field happens immediately after the allocation in ff_cbs_init(), so the whole CBS code may presume that any CodedBitstreamContext has this set. Lots of code already presumed this, yet ff_cbs_close() did it inconsistently: It checked before checking whether the CodedBitstreamType has a close function; yet it simply unconditionally read ctx->codec->priv_class. Coverity complained about this in issue #1473564, which this commit fixes. Reviewed-by: Mark Thompson <sw@jkqxz.net> Signed-off-by: Andreas Rheinhardt <andreas.rheinhardt@gmail.com>
* avcodec/nvenc: base timestamps on frameIntervalPMartin Storsjö2021-03-121-1/+1
| | | | | | | | | | | | | If b-frames were enabled implicitly (if max_b_frames wasn't set by the caller at all, since a0949d0bcb0eee2f3fffcf9a4810c0295d14c0dc), we wouldn't offset dts at all, producing invalid pts/dts combinations (causing loud warnings by ffmpeg, or muxer errors if passed without an extra cleanup pass). Instead use frameIntervalP for offsetting, which should always be accurate. Signed-off-by: Timo Rothenpieler <timo@rothenpieler.org>
* avfilter/vf_uspp: Fix leak of packet side dataAndreas Rheinhardt2021-03-121-0/+1
| | | | | | | | | | | The uspp filter uses a special option ("no_bitstream") of the Snow encoder to suppress it from generating output. The filter therefore did not unref the packet after usage, believing it to be blank. But this is wrong, as the Snow encoder attaches quality stats side data to the packet.

* avformat/gopher: Add support for Gopher over TLSparazyd2021-03-118-5/+38
| | | | | | | | | | | | | | | | This commit adds a "gophers" handler to the gopher protocol. gophers is a community-adopted protocol that acts the same way like normal gopher with the added TLS encapsulation. The gophers protocol is supported by gopher servers like geomydae(8), and clients like curl(1), clic(1), and hurl(1). This commit also adds compilation guards to both gopher and gophers, since now there are two protocols in the file it makes sense to have this addition.
