Hello, I use the testOnDemandRTSPServer to stream live video (captured using an analog camera and encoded to MPEG 4 ES using a co-processor). I use ByteFileStreamSource.cpp in (ASYNCHRONOUS mode) as a base model for my device. I have modified doReadFromFile in such a way that it reurns an MPEG 4 frame from the "codec engine"(capture device + mpeg 4 encoder).
I am having problems with the BANK_SIZE defined in StreamParser.cpp. Since I keep on reading from the codec engine and filling data untill BANK_SIZE (am I right ???) . When I reach the boundary (around BANK_SIZE) and I read X bytes and if adding X bytes would exceeed BANK_SIZE I end up with an error (and a visible glitch) at the decoder (mplayer compiled with LIVE555 support and MAX_RTP_FRAME_SIZE increased to 100000). Here is the output at the mplayer end: [mpeg4 @ 0x889a290]Error at MB: 89 [mpeg4 @ 0x889a290]concealing 1584 DC, 1584 AC, 1584 MV errors [mpeg4 @ 0x889a290]ac-tex damaged at 20 17 [mpeg4 @ 0x889a290]Error at MB: 802 [mpeg4 @ 0x889a290]concealing 884 DC, 884 AC, 884 MV errors [mpeg4 @ 0x889a290]ac-tex damaged at 12 22 Here is the debug output(newly added) at the Server end, ---------------------- ByteCount exceeded ---------------------- bufferSize = 79020 byteCount = 9954316 ---------------------- ByteCount exceeded ---------------------- bufferSize = 13086 byteCount = 999549 and the explanation: bufferSize - size of frame returned by the codec engine. byteCount - current amount of bytes I have filled into "fTo" buffer What should I do to ignore the last frames since they exceed BANK_SIZE ? or my understanding of the problem is flawed ?. I can stream videos with really low latency using live555 server. The only glitch I have now is there error happening once in 30 sec or so. Any suggestion on how to fix this would be of great help.
