Hello All, I have made dump of DTMB streams (digital TV standard in China, like DVB-T in Europe, etc).
Here is all files shared (50MB from each multiplex frequency): https://drive.google.com/drive/folders/1FOdZyQitKQXwBoyRlnRu34mP9fXcVBLn?usp=sharing Here is noted issues: * artifacts if we try to play: ffplay sands-754mhz.ts cavs video codec reported: Stream #0:13[0x17d]: Video: cavs (B[0][0][0] / 0x0042), yuv420p, 720x576, 25 fps, 25 tbr, 90k tbn, 25 tbc looks like it's implemented in ./libavcodec/cavsdec.c. Do we have here video stream not fully compatible with ffmpeg's implementation of cavs ? Should I create ticket in https://trac.ffmpeg.org ? * no resolution detected and no playback: ffmpeg -i sands-522mhz.ts looks like because it's scrambled: PID: 6201 (0x1839) [= ] transport_scrambling_control: 2 (0x02) [= TS packet scrambled with Even Key] adaptation_field_control: 1 (0x01) [= no adaptation_field, payload only] continuity_counter: 11 (0x0b) [= (sequence ok)] In this case it's ok, not a problem. May be someone seen CAM modules to descramble this streams ? Following CA system id's reported in PMT: CA_system_ID: 26882 (0x6902) [= >>ERROR: not (yet) defined... Report!<<] CA_system_ID: 19193 (0x4af9) [= >>ERROR: not (yet) defined... Report!<<] CA_system_ID: 19238 (0x4b26) [= >>ERROR: not (yet) defined... Report!<<] And one file is playing correctly (sands-722mhz.ts) - it looks "normal" (h264, mp2). -- Abylay Ospan, JokerSys http://jokersys.com _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-devel
