* avformat/segafilmenc: Remove redundant checksAndreas Rheinhardt2020-02-22
| | | | | | | | | | | | | | | | | | If an audio stream is present, the Sega FILM muxer checks for its compability with the container during init, so that the very same check needn't be repeated during writing the trailer. Essentially the same is true for the presence of a video stream: It has already been checked during init. Furthermore, after the check for the presence of a video stream succeeded, a pointer is set to point to the video stream. Yet said pointer (which was NULL before) will be derefenced anyway regardless of the result of the check. Coverity thus complained about this in CID 1434155 and removing this pointless check will also fix this issue.

* avformat/spdifenc: fix TrueHD streams over 48kHzAnssi Hannula2020-02-20
| | | | | | | | Commit 36e156bef02 ("avformat/spdifenc: fix handling of large TrueHD frame") added an obviously incorrect bitshift that caused incorrect samples-per-frame calculation for TrueHD streams over 48kHz. Fix that.
* avformat/spdifenc: fix handling of large TrueHD framesAnssi Hannula2020-02-20
| | | | | | | | | | | | | | | | | | | | | The TrueHD IEC 61937 encapsulation code uses a very naive method of always inserting 24 TrueHD frames evenly in a MAT frame. This does not work for larger frames as they may exceed the size of 1/24th of a MAT frame. To fix that, use the input_timing field in the TrueHD frame to determine the proper position of the TrueHD frame in the MAT frame. That field is basically a dts field, telling the time to feed this frame to the decoder in sample count units. This can cause a TrueHD frame to be split between two MAT frames, so a second concatenation hd_buf is added, alternating with the first buffer. Large frames are preceded by smaller frames that have input_timing values that cause the frames to be sent out faster than the nominal rate (i.e. increasing decoder latency, long decoder buffer), allowing the larger frames to then be sent out slower than the nominal rate as the decoder has enough data buffered to keep it busy.
* avformat/spdifenc: make hd_buf an arrayAnssi Hannula2020-02-20
| | | | | | | | This is preparation for adding a second hd_buf in a followup commit. Also, slightly improve the comments for hd_buf_x members to clarify which ones are actually used and kept up-to-date depending on which codec is being muxed.

* avformat/wtvdec: Forward errors when reading packetAndreas Rheinhardt2020-02-19
| | | | | | | | | | | | | | | wtvfile_read_packet did not abide by the requirements of an AVIOContext's read_packet-function: If it did not read anything, it returned zero, which currently leads to a warning in read_packet_wrapper in aviobuf.c. Said warning will be an av_assert2 as soon as FF_API_OLD_AVIO_EOF_0 is zero (probably the next major version bump). So instead forward the error code from the underlying protocol. This error/assert is triggered in the wtv-demux FATE test.
