* pthread_frame: merge the functionality for normal decoder init and ↵Anton Khirnov2020-04-101-3/+0
| | | | | | | | | | | | | | | | init_thread_copy The current design, where - proper init is called for the first per-thread context - first thread's private data is copied into private data for all the other threads - a "fixup" function is called for all the other threads to e.g. allocate dynamically allocated data is very fragile and hard to follow, so it is abandoned. Instead, the same init function is used to init each per-thread context. Where necessary, AVCodecInternal.is_copy can be used to differentiate between the first thread and the other ones (e.g. for decoding the extradata just once).

* avformat/matroskaenc: Don't fail if reserved Cues space doesn't sufficeAndreas Rheinhardt2020-04-021-2/+3
| | | | | | | | | | | | | | | | | | | | | | When the user opted to write the Cues at the beginning, the Cues were simply written without checking in advance whether enough space has been reserved for them. If it wasn't enough, the data following the space reserved for the Cues was simply overwritten, corrupting the file. This commit changes this by checking whether enough space has been reserved for the Cues before outputting anything. If it isn't enough, no Cues will be output at all and the file will be finalized normally, yet writing the trailer will nevertheless return an error to notify the user that his wish of having Cues at the front of the file hasn't been fulfilled. This change opens new usecases for this option: It is now safe to use this option to e.g. record live streams or to use it when muxing the output of an expensive encoding, because when the reserved space turns out to be insufficient, one ends up with a file that just lacks Cues but is otherwise fine.

* avformat/avformat: Update av_read_frame() documentationAndreas Rheinhardt2020-03-291-0/+4
| | | | | | | | | | | | | This commit updates the documentation of av_read_frame() to match its actual behaviour in several ways: 1. On success, av_read_frame() always returns refcounted packets. 2. It can handle uninitialized packets. 3. On error, it always returns blank packets. This will allow callers to not initialize or unref unnecessarily.

* avcodec/avcodec, avpacket: Return blank packet on av_packet_ref() failureAndreas Rheinhardt2020-03-281-0/+4
| | | | | | | | | | | | 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.
