  1. Hi, not sure if this is the right forum - please advise a more suitable forum topic if known.



    I have a video from a client (dumped from an RTP stream, in MPEG2 format), which displays terribly in all video players I throw at it (VLC, FFPlay, Media Player Classic, MPC-HC).

    bbbb.raw

    The output from ffprobe,

    Code:
    .\ffprobe.exe -i .\bbbb.raw -hide_banner
    Input #0, mpegvideo, from '.\bbbb.raw':
      Duration: N/A, bitrate: N/A
      Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, top first), 720x480 [SAR 8:9 DAR 4:3], Closed Captions, 29.97 fps, 59.94 tbr, 1200k tbn
        Side data:
          cpb: bitrate max/min/avg: 3596000/0/0 buffer size: 1835008 vbv_delay: N/A
    The footage through ffplay looks like this,

    ffplay_01.png
    ffplay_02.png
    ffplay_03.png

    The footage through VLC looks like this,

    vlc_01.png

    ffplay generates the following logging,

    Code:

    Has anyone seen the visual artefacts in other videos, or might know what could be the cause of this?

    Are there any decoders or setting which might help in producing a clear decoding of the video?

    Is there anything clearly/obviously bad with the raw dump file?

    I've seen that from JVC DVD recorders.

    I'm not sure what's different about the Encoder they are using, but would love to understand it.

    It is "not" corrupt.

    Its not strictly a GOP issue.. its sort of like they are inserting additional "info packets" into the stream that have nothing to do with the video, but the vast majority of decoders attempt to decode it as video packets.

    I have never figured it out.. but I suspect if the nature of the extra info were stripped out.. or passed through a filter to remove them the video would be artifact free.

    I just don't understand enough about the data stream.

    I do know that playback through the JVC hardware decoder, automatically strips out these extra info packets and the video is artifact free.

    I don't have MainConcept.. but their software decoder is far more comprehensive than the "freebie" decoders in many free players.. it might be smart enough to strip these packets out or at least ignore them.

    "A wild guess" is it maybe some type of professional pseudo "timecode" but that is only a guess.
