I confirm the distorted sound with this file. If I extract the .aac audio using the "-acodec copy" feature in ffmpeg, the resulting .aac audio plays in melt without the...

Here are the commands our CI system runs to execute the tests. Might save you a few seconds of googling: https://github.com/mltframework/mlt-scripts/blob/master/test/test_qtest.sh#L96 https://github.com/mltframework/mlt-scripts/blob/master/test/test_qtest.sh#L111

Modify this file to add a new test function: https://github.com/mltframework/mlt/blob/master/src/tests/test_playlist/test_playlist.cpp The function should create a playlist (add elements as necessary), read the current position, make modifications and then read the...

Through a series of trial-and-error tests, I have been able to reduce the test file significantly: [final-job_reduced.xml.txt](https://github.com/mltframework/mlt/files/6873072/final-job_reduced.xml.txt) Now it boils down to: * One clip with a fre0r filter applied...

> Out of curiosity, what is the name of the fre0r filter in Shotcut, so that I can get an better idea of what's happening? frei0r.IIRblur blur_gaussian It would be...

I would guess that the problem is probably not 10bit. it is probably the colorspace: bt2020nc/bt2020/smpte2084 I'm not sure if BT2020 colorspaces have been properly implemented in MLT

Also, what version of MLT are you using? There may have been some related improvements recently: https://github.com/mltframework/mlt/commit/adc5a2284b3a1073cb364c5f07d1d7c97e94c937#diff-40048f17cd89d43fba3be583ace3aa80 Regardless of whether MLT can correctly convert from BT2020, it for sure does...

I can confirm this behavior. This command illustrates the problem better by adding a background color to the text: ``` melt -profile hdv_720_25p \ -track qtext fgcolour=white text="1234567890 1234567890 1234567890...

A couple of comments for your consideration. I do not know how hard these would be to implement: 1) In the undo history, it would be helpful if the history...
