#9154: SVQ1 fourcc is wrong for AVI container
-------------------------------------+-------------------------------------
Reporter: cecodere | Type: defect
Status: new | Priority: normal
Component: | Version:
undetermined | unspecified
Keywords: SVQ1, | Blocked By:

-------------------------------------+-------------------------------------
Summary of the bug: When using the svq1 codec and using AVI as output
container, the fourcc output may be invalid, as it is in lower case while
in Qt it is in upper case, so it cannot be recognized by ffdshow. VLC does
accept both svq1 and SVQ1 as AVI fourcc.
How to reproduce:
{{{
% ffmpeg -y -benchmark -i foreman_cif.avi -codec:v svq1
foreman_cif_svq1_ffmpeg.avi 2>foreman_cif_svq1_ffmpeg.avi.txt
ffmpeg version : ffmpeg-4.4-2460-2c6f532-win32-static-xpmod-sse.7z
built on 2021-01-02
}}}
Workaround:
{{{
% ffmpeg -y -benchmark -i foreman_cif.avi -codec:v svq1 -vtag SVQ1
foreman_cif_svq1_ffmpeg2.avi
}}}
