[FFmpeg-devel] [PATCH] avcodec/h264_mp4toannexb: fix missing SPS/PPS to IDR frames

[Zhao Zhili]

From: Zhao Zhili <zhilizhao at tencent.com>

If there is a single group of SPS/PPS before an IDR frame, but no
SPS/PPS after that, we will miss the chance to reset
idr_sps_seen/idr_pps_seen. The result is missing SPS/PPS for all
IDR frames except the first one.
