[Live-devel] Conversion from H.264 to MPEG2 Transport Stream

[Dunling Li]

The demo program testH264VideoToTransportStream is stuck at the line
"(void)bv.get_expGolomb(); // frame_crop_right_offset" in
H264VideoStreamParser::analyze_seq_parameter_set_data, because get1Bit
always return 0 due to fCurBitIndex >= fTotNumBits.

The beginning bits of my video clip is 00 00 00 01 67 42 80 1e da 05 87
c4 00 00 00 0168 ce....
The video clip can be displayed in VLC player. Could you point me how to
fix this?

Thanks
Dunling

Dear Ross,

Thank you so much for releasing the new version  of LIVE555 so quick. I
tested the demo "testH264VideoToTransportStream" using 4 second h264
video clip, the program stucked at endless loop and didn't write any
data to the output file. When I stepped into the codes, it got into the
following conditions
1.  "return 0;  // the parsing got interrupted" in function
H264VideoStreamParser::parse()  
2. acquiredFrameSize=0 in MPEGVideoStreamFramer::continueReadProcessing

    // We were unable to parse a complete frame from the input, because:
    // - we had to read more data from the source stream, or
    // - the source stream has ended.
    This happened when I reduced BANK_SIZE to 15000 which is larger than
size of my video clip. 

Could you help me or guide me to fix this?

Many thanks

Yes, we can now convert H.264 video elementary stream files into 
Transport Stream files.  I have now released a new version 
(2011.01.20) of the "LIVE555 Streaming Media" code that now includes 
a new demo application (in the "testProgs" directory) named 
"testH264VideoToTransportStream".
