When running telxcc on the file, the subtitles are correctly extracted.

It seems that autodetection for video type fails in this case. It works if the parameter "in=ts" is added to the command line.

Probably just forcing ts as input type would work. Seems like it's
incorrectly detecting it as a MP4.

@workflowsguy can you provide the sample file (a small sample cut from the original should be enough)

It might be related to a broken header or transformed file from MP4 to TS, since in the file-detecting program, the MP4 detection procedure goes before TS detection procedure and it did detected a valid sync-code in box.

File-detecting program detect only "mfra" mp4 box in this video which is a trailer and it is assigned weight 3 in ccx_stream_mp4_boxes . So, program detects file as mp4. "mfra" box weight should be "1" so that other box too can confirm file is mp4.
