Ffmpeg : How to fix error "Please choose an encoder manually" ?
9 juillet 2023, par AlexI am trying to convert a x265 videofile to a x264 format so it can be played on a television. I am trying the following command


ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 test.mp4



to select videos stream 0:0 for video, stream 0:1 for audio and stream 0:2 for the subtitle. However I get an error


Automatic encoder selection failed Default encoder for format mp4 (codec none) is probably disabled. Please choose an encoder manually.
Error selecting an encoder



How to fix this command ?


P.S. I am not an expert in
ffmpeg
or videos conversion/formats/encodings/audio formats/subtitle formats.

I found EXACTLY ONE google search result with the exact error phrase HERE. And that is not helping as I do not even understand the first sentence.


Below is the output for the first three streams :

I found a related question HERE whose answer I do not fully understand. However, I tried the following command


ffmpeg -i input.mkv -f mp4 -vcodec libx264 -preset fast -profile:v main -acodec aac -map 0:0 -map 0:1 -map 0:2 -c:s mov_text test.mp4



but got a new error


Error initializing output stream: Error while opening encoder for output stream #0:0 - maybe incorrect parameters such as bit_rate, rate, width or height



I thought I am defining an "encoder" for output stream "#0:0" (which I think is video), namely libx264. So what else to do here ?


I tried
-acode copy
and also to use-qp 0
in the command line which all did not work.
