Hello Miguel,

Take a look at the captures the workflow get form the video. In my case I
get a grey pattern captures in 90% of the cases, so the OCR was not able to
recognize almost anything. I solve it installing again ffmpeg and all the
dependent packages. Now the OCR works almost perfect. But I have some issue
with the ffmepg version, because recordings longer than 5 min I get errors
during the video and audio mux. (With version 1.2 I didn't get these
errors, only with 1.3. Maybe I install something in a different way).

So I am not sure if you have this problem with the OCR but it is possible.


Regards,

Fernando Hernández Esguevillas.

PD.- Si tienes alguna duda sobre como instalar la versión más reciente de
ffmpeg me lo comentas y te paso algún link. Aunque es fácil encontrar la
información en google. Un saludo.
