Hi, now that I got working PS and PES from /dev/ost/dvr0 (thanks, Marcus!), I want to convert PES which is read from /dev/ost/demux0 to a TS and/or to a PS. The reason for this is, that it is not possible to view TV while reading from dvr0, as opposed to reading from demux0 (at least on the dbox2).
First I tried to write TS headers myself until I found write_ts_header(), which seems to do a good job. Now I have 2 main problems: If I filter for one pid, the result almost seems to be fine (e.g. about 400KB/s, but distorted video). If I filter for two pids, the data rate does not increase but instead drops to about 80KB/s. I am using poll() to see which demux file descriptor has data available. How large should the read buffer be for every PES? As far as I understood, a TS packet which contains the beginning of a PES packet must begin with the PES packet as the first data byte. If the size of the PES packet ist smaller than 184 bytes, then the missing bytes must be padded. But what to do when the PES_packet_length is set to zero? Do I have to search for the next PES packet manually? What is the maximum size of a PES packet? 0xFFFF?
