HI,
I am working on ISDB-1Seg..
I need to extract video PES from TS and give the same to decoder.
Since there is no PES length in the case of video data, i am storing the PES data from PUS(payload unit start indicator-1) and till the next PUS set.
Is the above methodology is proper? If not, please tell me how can i proceed?

Second problem is, in a single PES there are more than 1 video frame, in some cases its going upto, 6frames? as per spec, is this possible?

I collected the video data(per PES basis) and giving it to the decoder. Since there is a single PTS for all the frames, its displaying all of them at once which makes the output image speed and jerky. when i am playing the extracted data in VLC, its showing fast for few seconds and then freeze and again fast moving... How can this problem be rectified.
Thanks in advance.

Question 1:
You can use h264visa (http://h264visa.daydayup.info/) to analyze your isdb-t 1seg stream, both on mpeg2 ts level and h264 level, you can see the PES structure.

Question 2:
Yes, it is possible, please use SEI to interpolate missing PTS's。

NOTE BY MODERATION TEAM: This product is not free and is quite expensive.

What makes you say that? I just looked and it appears to still be free.

Well, when you run the program, you can either enter your registration key or you can run a 30-day trial. I'd call that none-free :p

it's free during 30 days. After, you need to buy it...

edit: too late.

You can download and trial it for 30 days. After that, you must buy license(s) if you want to continue using it.

And at $80 for the baseline version, $269 for the mobile solution version, and $450 for the standard version, nobody with just a passing interest in it is going to be getting it (well, legally).

I see. Well, they can answer specific queries, such as in this thread. But they cannot originate threads just to spam their products. They should also mention that the solution is not free when replying to queries. The signature is now spam and will be removed.
