| Summary | 0000659: Long record with splitted MTS files | ||||
| Description | Due to FAT16/FAT32 limitation, camera using MTS files split it into chunks during long record. MTS files use frames for audio and video. On some camera, a frame can be divided between the two files. Cinelerra cannot recover this lost frame even if it have all data. A function to virtually join those chunks from a long record will be helpful. | ||||
| Steps To Reproduce | Use some video camera with AVCHD/MTS output (my case, panasonic camera) Make a long record to have 2 or 4Gb file. Try to assemble those files without and with a concatenation (using command lines from OS). | ||||

An possible option : make an assistant in order to create a virtual file with fuse and load it ( example : https://github.com/schlaile/concatfs ) |
|
|
well, I think I saw quite a lot of splitted hairs on ffmpeg-user when concatenation of two files for some reason go wrong ... So I am not sure this specific request easy to handle ... @Kabak Does ffmpeg (command line) works for your cases? |

The ffmpeg concat not seem to work. First track : Raw file Second track : files concatenated with linux "cat" or "fuse" command Third track : tried the "ffmpeg -i "concat:input1.ts|input2.ts|input3.ts" -c copy output.ts" command pattern but it seem to have some issue : - videos and audio are synced at the joint - video concatenated with ffmpeg at the end seem to have more frame - audio concatenated with ffmpeg is not synced at the start Using FUSE (like concatFS does) seem's to be the best way. It create a virtual file (no need to use disk space) and it can be used like an normal video file (already tested). To determine file which needed to be joined, i extract tags with the command ' ffprobe -loglevel 0 -print_format json -show_streams -show_streams "file.mts" ' (in the .txt) We can see the "start_time" is different between files so we can easily determine if two consecutive filename is from the same "shot" or not. (can be extracted with ' ffprobe -loglevel quiet -select_streams 0 -show_entries stream=start_time -i "01150.MTS" ' ) ffprobe tags.txt (6,431 bytes)
ffprobe -loglevel 0 -print_format json -show_streams -show_streams "01150.MTS"
