Comment (by tmm1):

 I discovered that I can fix the ffprobe output by telling the mpegts
 demuxer not to parse H264 streams:

 {{{

          st->request_probe = AVPROBE_SCORE_STREAM_RETRY / 5;
      }
 +    if (st->codecpar->codec_id == AV_CODEC_ID_H264) {
 +        st->need_parsing = AVSTREAM_PARSE_HEADERS;
 +    }

      /* queue a context update if properties changed */
      if (old_codec_type != st->codecpar->codec_type ||
 }}}

 However, then there are problems decoding the video for some reason.
