Re: [FFmpeg-devel] MpegTS contribution question
For now I'm just reading and storing EPG data, once this part is done I'd like to do what you said. But first we will have to think of an easy way to change/insert descriptors inside a specific table.

Re: [FFmpeg-devel] MpegTS contribution question
Hello Anthony, I'm not really the best to answer your questions, as I'm also a fairly new contributor (my patches seem to be languishing due to a lack of feedback and a lack of time on my part pushing the issue). I've been working on getting support into mpegts for ATSC compliant descriptors of which EIT tables are a glaring omission in large part due to the amount of work needed to support them. So to say the least, I'm excited about your patches! I'll take a look at your patches but one thing I would like to know if you've considered, is whether or not your code supports modifying the EIT tables, ie updating tables_version when the tables are modified?

[FFmpeg-devel] MpegTS contribution question
Hi, I'm currently doing my first contribution to ffmpeg by adding EPG support in the mpegts format. For now, i succeeded to add support for EIT table and majority of its descriptors and can read/export EPG events in a .csv file. But I don't know on how to organize it now. Do I make a new codec for epg and a data stream? Do I keep those information « hidden » and present them only in metadatas plus functions api to export them? For those who wants to see where I am at: https://github.com/spnngl/FFmpeg/tree/epg2 Some remarks: * For now I use linked list to store EPG events but I may change for something simpler. * I made separate descriptors code to be able to use it on others tables later. I want to add NIT table support and maybe others if i succeed to finish EPG. * EPG/descriptors files are all in libavformat for now, they need to be moved Thanks ___ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
