Hoping for some help with converting Freeview recordings made on a Visione VE4000 set top box, a problem that is driving me to distraction.

I have a VE4000 Freeview box, that records Freeview shows to a USB HD in High Definition. As I have reviewed elsewhere, not great as a PVR but it works for the occasional recording. The recordings each seem to go in a separate directory under the \recordings folder, prefaced by a numbercal code that is clearly a timestamp. Within this directory I get a an .ifo file, and a further sub-directory with the actual recorded files. These files consist of a small (1MB) file with a .idx extension, and a series of files numbered sequentially (001, 002,003 etc) with .ts extension, that seem to be the recording broken into 1.46GB chunks. GSpot tells me that the files are MPEG-2 transport streams with video type mp2t.

I am trying to convert these into a more normal computer file (either XVID or MP4 would suffice) for storage, playback on other devices, removal of commercials etc.



  • My WD HD TV media player, which is supposed to play .ts files, won't play them.

  • Super (version 2010 build 37) won't convert them (error message as soon as I hit go)

  • MediaCoder (version 0.7.3) won't convert them (it gives error code 17, the explanation of which is in Japanese on the website http://wiki.mediacoderhq.com/index.php/Error_Codes#017)

  • Handbrake (version 0.9.4) won't convert them (it also crashes)



Do any of the gurus out there have any idea how these chunks can be combined and converted to a more normal file format?

Help and suggestions greatly appreciated.

I have never used the VE4000, but use the DSE/Zinwell 620HD (with the Olevia firmware) to record onto HDD.

This produces three files, probably analogous to yours. As I'm sure you've worked out, the only files you really need are the TS files. (The other files likely contain the programme titles, and indices to navigate quickly through the mpeg-ts.) These TS files are merely the relevant packets, as your recorder receives them, appended one after another to the TS file.

I have used ffmpeg (a command line utility, but if you ignore the complicated stuff can be easy enough to use) to convert these files. (Try: [i]ffmpeg -i VE400FILENAME.ts -target vcd test.mpg[/i]) I have also used handbrake, but have experienced crashes.

As far as I'm aware the video itself can be easily converted, the only problem is the audio. Freeview uses HE-AAC, which is (mistakenly?) interpreted as MP2, and can cause some programs to play it as a series of loud bleeps and clicks, or to crash when try to read the audio.

I'm not sure if anyone has found software that can use this audio format in a TS file natively without problem.

I'm developing software that can edit some of the Zinwell files ( http://code.google.com/p/zorve/ ). Are you able to send me an example copy of the .ifo file and the .idx file? I'm sure these have nothing in common with the Zinwell/Olevia version, but i'd be interested to see them.

Have a go with VideoReDo TVSuite V4 with H.264 (14 day free trial) and a good support forum. http://www.videoredo.net/msgBoard/showthread.php?t=15759

Thanks for the suggestion, but VideoReDo TVSuite also failed. It wouldn't join any of the 1.46GB "chunks" of .ts stream correctly. While it did display the video in individual chunks correctly, it choked on the sound - giving messages about unsupported audio formats.

The vendors of the box weren't that helpful. I corresponded with them and their response is -pretty much "we don't know how to do this either, you could try SUPER". Super, or course, doesn't work.

I think I am pretty much ready to give up on this one. I think consigning the Visione box to the rubbish (or the VCR in the spare room as a backup recorder) and moving to a laptop with a cheap USB tuner stick is the way I will probably go.

After forgetting it for a while I have returned to this problem (which is still bugging me), and have made some progress. Using a programme recorded from TV1 (the Pacific), I have found:

1.  The chunks can be combined using copy /b chunk1 chunk2 chunk3 ....  output file

2.  TSRemux can turn the output file into a properly formatted .ts stream. It comes out showing (according to mediashow) a 7,013 kbps video stream at 50FPS encoded in AVC, and MPEG Version 2 Layer 1 audio at 192kpbs, which is much more sensible than the output from the original file.

3. The remuxed file can be transcoded to Xvid etc, and it works using Super (and several other packages). The resulting video is superb. But, annoyingly, no matter what I do, it comes out with no audio, and mediainfo shows the transcoded file as having no audio. I have installed the Monogram AAC codec, which is what I thought was needed, but it makes no difference.

So, I am on the home straight, and have the files combined and the video working. If any of the gurus among you know how to deal with transcoding the audio stream I will be a happy man.

Thanks

NB: In case it helps, ull details of the audio stream (from mediainfo) are as folows:
