Download from Univision (NeuLion)

[rubiohiguey]

Hello

I am trying to capture streams from Neulion (new streaming provider for Univision)
They service the file as downloadable 2-second MP4 (H264) chunks.

Example:
http://nldsvod.cdnak.neulion.com/nld...p4/00/0000.mp4
http://nldsvod.cdnak.neulion.com/nld...p4/00/0002.mp4

I AM able to download those chunks, and even join them fine with MP4Box.

The video can plays somewhat fine (there are some bad, fragmented or pixelated frames) but more or less it's fine. What concerns me, however, is that there are many "strange" chunks, which download as mp4 but I cannot open them in any audio/video program, even if I add them to Premiere Pro they "show" just as one frame no audio/video ... however, they have "full" size the same as other regular mp4 chunks do:

e.g. strange chunk (no video size, video cannot be seen, audio can be extracted)
http://nldsvod.cdnak.neulion.com/nld...p4/00/0034.mp4
http://nldsvod.cdnak.neulion.com/nld...p4/00/0042.mp4


QUESTION: Does anybody know what to do with these "strange" chunks?


EDITED Got this resolved through another forum, the issue with the "strange" chunks is that these chunks have no I frames. The solution is to join all chunks in sequence using ffmpeg, and while ffmpeg gives a truckload of errors, the video seems to play fine and also there seem to be no syncing issues.
