Hello, I've been using the Linux DVB API to grab DBV-S MPEG2 video packets using a TechniSat S2 card. But something seems odd about DMX_SET_PES_FILTER. It returns a TS packets for my pid just fine, but by MPEG2 frames have no PES headers! The raw compressed MPEG2 frames just immediately follow the TS/adapation-field headers directly. When I wrote my TS packet decoder, I was expecting to have to decode PES headers after the TS header. But instead I found the raw compressed frames. They decode fine (with ffmpeg's libavcodec mpeg2 decoder,) and they look fine when rendered using SDL. But besides my own program, I can't get vlc or mplayer to decode this stream. Both vlc and mplayer sense a TS stream, but then they never render anything because, I suspect, that they can't find PES headers. So, two questions: 1. Am I crazy or is DMX_SET_PES_FILTER returning a non-standard TS stream? 2. Is there a way to receive a compliant MPEG-TS (or MPEG2-PS,) stream? 3. Should I use DMX_SET_FILTER instead? 4. If so, what goes in the filter/mask members of the dmx_filter_t struct? Thanks, Bob PS: I use the following to filter on my video stream pid (0x1344): struct dmx_pes_filter_params f; memset(&f, 0, sizeof(f)); f.pid = (uint16_t) pid; f.input = DMX_IN_FRONTEND; f.output = DMX_OUT_TS_TAP; f.pes_type = DMX_PES_OTHER; f.flags = DMX_IMMEDIATE_START; -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
