Split tst_qavplayer.cpp into multiple test files

[fedorkrivitskiy]

For now tst_qavplayer.cpp has more than 3600 lines of code with over 70 tests. The idea of this issue is to split this huge test file into multiple files. Each file could be responsible for different testcases e.g. audio tests, video tests, subtitle tests etc.

Proposed structure:
common/
core/
audio/
video/
seek/
files/
io/
filters/
multimedia/
conversion/
codecs/
muxer/
misc/
main/ - Entry point that runs all test suites

Thanks, it is correct that too many lines. Also it is true that on CI it is sometimes hard to see the output of the tests.

Just small note, invented 2 types of unittests, based on QAVDemuxer and QAVPlayer.
All tests that require only QAVDemuxer go to tst_qavdemuxer.cpp.
All tests that require QAVPlayer go to tst_qavplayer.cpp.

F.e. if there was a need to check the muxer, it is enough to use only QAVDemuxer + QAVMuxerFrames/QAVMuxerPackets, since the muxers require streams and frames returned from the QAVDemuxer.

But testing QAVPlayer::setOutput() or multisource and QAVMuxerFrames ofc goes to player's tst_qavplayer.cpp.

so doing subdirs could be redundant since it should be only one test file per module, and looks there are no so many modules to test.

oh. you meant to have one executable file but impl tests in different files? this still exposes the issue with CI and very long output and need to wait to long to restart if one small test failed.

need to wait to long to restart if one small test failed.

damn, it is not an issue, since entire job is restarted, not one test, so making many small executables, won't help there
