Using ffmpeg to convert stream with delayed audio stream

Question

I am trying to use ffmpeg to convert this TS stream file to MP4. Note how there is no audio until around the 10-second mark. Whenever I try to convert (or copy) this TS file, I get no audio. I suspect this is because ffmpeg can't find an audio stream at the start of the file, but how do I get it to find the audio that begins later on?

For example, this is the output when I run this line ffmpeg -i beinold.ts -vf scale=1280:720 bein.mp4. I added the scale because otherwise, ffmpeg would return the whole MP4 as 270p, which is the resolution of the first few seconds. Note the lack of errors. Even running with -analyzeduration 15000000 does not work.

Answer 1

This works here:

ffmpeg -analyzeduration 15M -i beinold.ts -c copy bein.mp4

Audio starts around 9s. Resolution is preserved i.e. if the player supports decoder reinit, then you should see switch in resolution when that happens in the stream. VLC does, as does Potplayer (Windows).

Answer 2

Try winff video converter (graphical utility) to make this process easier.. It works fine there..
