[FFmpeg-devel] [PATCH v3 0/1] Add-probe_streams-option

[Nicolas Gaullier]

>The main idea is to always trust the descriptors, even if it means crashing.
>Typically, an mpegts file having no PAT/PMT will not be supported at all. There is a clear use case for that, for example when using ffprobe in front of a transcoder that is not ffmpeg and not able to handle such files.

I am surprised there was no reaction to this patch: there is for sure things to discuss about what is a proposal for now.
This patch is required for me before rolling out my patch serie for s337m support in WAV files.
(This v3 is just a rebased version)

Thank you!
