 tiff enc: odd-sized yuv410p tiff image decodes in other apps with
 visible green dots

Comment:

 actually this issue is not fixed, because this ticket is not about how
 ffmpeg decodes "out.tif" file, but how other apps like tiff2rgba and gimp
 decodes it, and green dots are still visible there

Comment:

 it looks like something has fixed this issue, but

 there is now a green line with

 {{{
 ffmpeg -i yuv410p.avi -vcodec svq1 svq1.mov
 ffmpeg -i svq1.mov out.bmp
 }}}

 conversion

 oh well

Comment (by Juan Navarro):

 Bug reporter here. I'd just want to mention that for the internal project
 that needed it, I've been successfully using the patched branch provided
 in comment:4, without issues, for the last 2 years.

 My real-world use case has been a program that records incoming RTP, with
 a command that looks like this:

 {{{
 ffmpeg \
 -protocol_whitelist file,rtp,udp \
 -fflags +discardcorrupt+genpts \
 -use_wallclock_as_timestamps 1 \
 -i input.sdp \
 -map 0:a:0 -c:a copy \
 -map 0:v:0 -c:v copy \
 -f webm -flags +global_header \
 -y recording.webm
 }}}

 So I'd like to endorse the changes proposed in the mentioned branch.

 The issue seemed to be, from what I understood in the patchwork
 conversation (comment:8), that the current code design of FFmpeg around
 signal handling does make a difference between handling signals for the
 main loop, and handling them within nested loops (and that's where the
 need for ''two'' signals came from, and the motivation for this report)

 I'd agree that the user experience of requiring two signals is already
 strange, but requiring them ''only some times'', makes it even more
 confusing. IMO it's all due to an internal implementation detail, which
 should not leak to the user.

 There is no way to retrieve vmaf score from the resulting frame produced

 {{{
 char *entries = nullptr;
 av_dict_get_string(resultFrame->metadata, , ',', '|');
 std::cout << entries;
 }}}

 I use this filter:
 {{{
 const AVFilter *vmafFilter  = avfilter_get_by_name("libvmaf");
 }}}

 The same cannot be used for [https://ffmpeg.org/ffmpeg-
 filters.html#libvmaf libvmaf]. The metadata dictionary is empty. I

 source code]. Storing to the frame is visible in the

 in the code.

 The only workaround is to call the
