Hey - please send me the files (healthy+broken) and I might take a look at some point. |
|
I also have the same problem, can I help? |
|
@rattkin Feel free to send me your files too - once I get around looking into this, they might be very helpful. If the files are large, please check if the bug is already reproducible with shortened files ( |
|
@anthwlock the shortened file works! |
|
@rattkin You can specify the size in MB as optional parameter, e.g. |

@anthwlock Thank you, it works, I get almost half of the video. |
|
The link shows me a 404 page. Please also include the reference file - Thank you |
Sorry I had problems uploading. Here are the video files: |

Same case, but for file 56G. |
Hello,
Due to lack of space on the first SD card, the camera continued recording on the second SD card. The content on the first SD card was not saved correctly during the switch.
I tried recover the content, but it seems to detect a length of 0s for all audio and video streams. Using the
-soption throws an assertion (src/mp4.h:298: bool Mp4::currentChunkFinished(int): Assertion 'cur_track_idx == last_track_idx_' failed). Details of the logs can be found at the end. Do you have any idea what might be causing this?I have also tried changing the version of ffmpeg using 3.4.13 and 3.3.9, but the problem is still the same.
Thanks for your help!
