When the -out=raw option is used, the ccextractor jumped to spupng output
format, generating broken files in spupng format without CC data.
With this fix, now it generates CC data in McPoodle's Broadcast format.

line. Otherwise the EOL characted is absent causing garbage value to be
present in SRT.
* Exporting the encoding of the captions from CCExtractor to Python so
that the python SRT generator can generate proper SRT files.
* Modified the include statement in extractor.h
* added python_extract to encoders_srt and the captions are being
extracted in needed format. Search for an alternative to asprintf

* added -out=pythonapi support for bitmap
* Setting the messages_target to 0 for output = pythonapi
* Added wrapper for setting -out=pythonapi. Checking if -stdout value can be used in python.
* adding the cc_to_stdout=1 value for -out=pythonapi. Thus generation of output file has been avoided. May be needed to change in future.
* added extractor for g608 grid. removed sami extractor. need to work on overlap of -out=pythonapi and -out=g608
* Removed overlap of -out=pythonapi by adding -pythonapi and
signal_python_api global variable.
* added support for seperate c608 grid catching. Need to test the output
via python.
* added support for seperate printing of text font and color in CE608.
Need to make sure that the function is inbuilt.
* ADDED ce608 GRID SUPPORT FROM PYTHON
need to discuss whether to keep the print_cc_grid function specific to
the module or make it user accessible.
Mostly it would be better to make it user accessible.
* made changes in the call_from_python_api function such that only
api_options is needed to be passed.
An if statement before the call to g608_extractor has also been added.
Waiting for Carlos to comment on the output generated till this stage.
* added a signal_python_api check before calling every write function.
Thus basic writing output can be avoided.
* Commented all calls to python_extract_time_based.
making changes to python_extract_g608 to be called only from the point
when a g608 caption is detected.
* Added pass_cc_buffer_to_python in encoders_common.c temporarily
redefined get_*_encoded from static to normal
included the above functions in encoders_common.h
* Added if-else statement for switch in encode_sub function.
This is done mainly for making sure no output is generated in the api
call.
* Added ccx_encoders_python.c
Defined pass_cc_buffer_to_python in ccx_encoders_python.c
added if else statement in encode_sub's switch to make sure that the output is not generated in case of -pythonapi call
* Removed __wrap_write from the entire code base.
It's declaration and definition are only present in CCExtractor.*
* Commented out the /dev/null part in ccx_encoders_common.c.
Proceeding further on checking for file generation.
* Added output_filename in array global variable and is generated in
init_write function.
included ccextractor.h in output.c to access global variable
signal_python_api for avoiding output generation in init_write and
invalid free in dinit_write.
* Modified the definition of init_write function for accessing
signal_python_api.
* Deleted the commented part of /dev/null in ccx_encoders_common.c.
* Added target_message=0 in -pythonapi param parsing in param.c to avoid
the API from printing to STDOUT.
Deleted the commented part of -out=pythonapi.
Thinking of adding a different param for silencing the output when the
call is made from python api.
* Removed __wrap_write from ccextractor.c and ccextractor.h.
* Added ccx_to_python_g608 and modified api_support.py file.
added documentation in ccextractor.c.
* added the generate srt script. However, some random characters are
coming in first line. Need to talk about this.
* Added SRT generator for python.
Using string to remove the garbage value.
Add code for srt counter and also the start_time and end_time
conversion.
* removed the trash characters and added code to print the timings.
However, the last blank frame also results in a print. Need to take care
of this.
* rectified the mistake of writing only timings and not captions.
now next step is to just make the timings print properly
* some minor changes before diving into extracting srt_counter from the made codebase
* Added extraction of srt_counter in python_extract via fflush
srt_counter-value.
Need to modify the processing in python.
* Added the entire method to extract captions and generate srt files. Next, step would be a to define a concise function for writing the srt
* Processing into a srt working properly.
Next step is to add the information of font into the caption text.
* the data is getting generated for proper SRT counters.
* A turning point to the appraoch.
Added END OF FRAME line for printing the data for every particular
srt_counter.
Proceeding further with the generation of srt by data manipulation.
* some minor bugs but the output srt is being generated correctly. However, The font and colour encoding needs to be done.
* Taken care of random characters. Need to discuss this with Carlos. Moving further to font/color processing.
* Taken care of random characters. Need to discuss this with Carlos. Moving further to font/color processing.
* Added fflush and cleaned up the python code of srt generation
* Added <i> tag for italics.
Proceeding further with other types.
* Added the code to check for underline.
However, need to check how CCExtractor generates srt when both italics
and underline are present. For now a new line is added if both are
present.
* Shifting for making changes in th i/O work.
* Stable ouput for samples with italics is being generated.
* Added the PYTHONAPI macro definition and testing for its existence in the set_python_api function.
* build script for linux is working correctly.
Build_library is showing error of invalid def of set_pythonapi.
Moreover, extractor has some memory seg fault.
* Added mod to set a MACRO as my_python_api to set the callback function.
Till now all calls to the reporter are commented.
Working on getting the reporter to print the lines.
* Changes have been implemented to bring reporter in working state.
For now a constant string is passed from extractor. Need to make the
proper parsing possible.
* Changed the code in extractor such that entire grid is returned to the
callback function.
Need to provide this grid to the write function and also cleanup the
codebase.
* Writing the outputted srt in a file called "temp.srt".
Need to modify init_write to push filename that is to be created in
python using callback.
* Added code to get start and end time simultaneously.
entire SRT is getting generated.
* removed ccx_python_encoders.c
* Compiling and executing on Windows
* Moved definitions get_line_encoded, get_color_encoded, get_font_encoded from ccx_encoders_g608.c to ccx_encoders_common.c.
Also, deleted the static definition of get_font_encoded from
ccx_encoders_webvtt.c
* added a write statement in write_cc_bitmap_as_srt
* Rectified transfer of get_line_encoded, get_color_encoded and
get_font_encoded from ccx_decoders_common.c to ccx_encoders_common.c.
Segmenting now doesn't destroys the whole encoding context, just closes and reopens the output file
Correct a wrong function prototype for process_hex()
OCR: Attempt to correctly deal with TessBaseAPIRecognize returning an error
Changed output for parse PMT to CCX_DMT_PMT instead of CCX_DMT_VERBOSE
- TS: If we don't have pinfo don't pay attention to the current_next_indicator bit.
(fixes problem with The Lion Guard_20170321_09301000.ts). Not sure this fix is the correct one but that's what VLC does.
If no -o is suppled with stdin/network etc, the output name generated
was NULL, leading to creation of files like `.srt` which were in
category of hidden files.
* Use own SBS-context structure to store SBS-data (fixCCExtractor/ccextractor#639)
* Search for BEST match of new string and SBS-buffer (instead of first appropriate..)
* all tests are fixed and passed
