Title: Interesting Bug
Post by: naszdom on April 06, 2017, 12:33:04 PM
I am using Avidemux 2.6.19

If I use smartcutter to edit a TS file from a satellite recording and then use Avidemux for a simple conversion to mkv (copy video/copy audio) it always fails.  You get messages that the video has been saved but seems to be incomplete and has not saved correctly.

If I do a simple conversion to mp4 it always works and then a simple conversion from mp4 to mkv will then work.

What does happen if you leave out smartcutter? What is the reason you resort to it in the first place?

You can edit .ts sat recordings with avidemux.
See small video demo at our YouTube Avidemux Demo channel: Fast Edit with Copy Mode (https://www.youtube.com/watch?v=avs5AvlSq4Y&index=9&list=PLLGMi2RSm8sbiUG2tfv8mcCzJoEsK3JVN)

Actually, the log indicates that quite a lot of frames in the video have invalid decoding timestamps. The MKV muxer seems to treat this irregularity stricter than the MP4 one.

I use smartcutter because its one of few programmes that will let you cut and preserve dvb subtitles in the output.  Programmes like videoredo will only keep text based subtitles. I'll have a go with avidemux but does it keep subtitles?

Regarding eumagga0x2a's point - I think it is smartcutter introducing invalid decoding timestamps. If you demux the edited TS and then try to remux into a mkv container it never works although the audio files seem complete.

No, not for now, perhaps in (distant) future.
