Bug ID: 511138
Summary: a
Classification: Applications
Product: kdenlive
Version First 25.08.2
Reported In:
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Title Clips & Subtitles
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
SUMMARY
Everytime after I add subtitles in anyway - either myself or using the speech
recognition feature I get an error in the UI saying `[filter avfilter.subtitles
] Unexpected return format` when I click on the play button or manipulate the
timeline in any way. And as a result the subtitles don't get rendered,
rendering them useless.
When I run kdenlive from the terminal and do the same action I get this
message:
```
[swscaler @ 0x7f35bc028680] Unsupported input (Operation not supported):
fmt:yuyv422 csp:bt709 prim:reserved trc:reserved -> fmt:yuv422p csp:unknown
prim:reserved trc:reserved
MLT: "[filter avfilter.subtitles ] Cannot get frame from buffer sink"
MLT: "[filter avfilter.subtitles ] Unexpected return format"
```
Also, when I try to render the project with the subtitles, the rendering
process crashes with the error log being just the following message on repeat:
```
[swscaler @ 0x7fdc341d3340] Unsupported input (Operation not supported):
fmt:yuyv422 csp:bt709 prim:reserved trc:reserved -> fmt:yuv422p csp:unknown
prim:reserved trc:reserved [filter avfilter.subtitles] Cannot get frame from
buffer sink [filter avfilter.subtitles] Unexpected return format
```
STEPS TO REPRODUCE
1. Create a new project
2. Add something to the timeline and ad
3.
