Unexpected Error when appending webm files: mkvmerge throws error when width and height are different
Am trying to append two webm videos that have different width
and height
. Firefox implementation of W3C's MediaRecorder
is able to record input having variable width
and height
, Chromium does not record variable width
and height
input; the width and height remain the same even when input width changes during the course of recording https://bugs.chromium.org/p/chromium/issues/detail?id=972470. Both browsers are able to playback Firefox's recorded variable width
and height
.webm
video.
Was not expecting mkvmerge
to throw an error
Error: The track number 1 from the file '1.webm' cannot be appended to the track number 1 from the file '0.webm'. The width of the two tracks is different: 768 and 480
when merging videos having different width
and height
(both recorded at the same browser to avoid the issue of Firefox and Chromium webm files being dissimilar which also throws an error).
